Customizing JPopupMenu's L&F

Hi all,
When removing all borders and overriding 'paintComponent(Graphics g)' methods there is still space at the bottom and top of a 'JPopupMenu' drop down menu. This space shrinks and grows as the menu size varies as well. How can I get at the space and remove it. I take it can't have anything to do with 'Insets' since it shrinks and grows so it must be a component.

Hi bbritta,
Thnx for looking into this. Tried, I have this for myPopupMenu. I have this for JMenu and JMenuItem as well as 'setBorder(null)' for either and all components associated I use for my menu. Still no change.

Custom JButton for JPopupMenu

I need to make a custom PopupMenu Button . This button needs to be added to the custom JPopupmenu . This custom button must have the look and feel of a typical menu item. Basically it should have a typical features of a checkboxmenuitem where I have an check.jpg for check and uncheck of the button. How do I reproduce the look and feel of a menuitem. What changes do i make in the below code. Basically no border, button press should not be there. It should not look like we are adding JButtons to the user
import javax.swing.Action;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.border.EmptyBorder;
public class XCheckedButton
 extends JButton {
 private boolean flag;
 private ImageIcon checkedIcon;
 public XCheckedButton() {
 super();
 public XCheckedButton(Action a) {
 this();
 setAction(a);
 public XCheckedButton(Icon icon) {
 super(icon);
 public XCheckedButton(String text, Icon icon) {
 super(text, icon);
 public XCheckedButton(String text) {
 super(text);
 public ImageIcon getCheckedIcon() {
 return checkedIcon;
 public void setCheckedIcon(boolean state) {
 this.checkedIcon = checkedIcon;
}

Thanks a lot. Here are my 2 java files and right below is the probelm I am facing when USing JMenuItems. Thats the reason why i switched over to JButtons.

Problem 1: Not able to Scroll down when frame is Large
My application is a large frame and when I invoke the JPopupMenu on it I am not able to scroll.
In the example application also I found the same problem when I maximize the frame. I am able to see the JPopupMenu but not able to scroll on it.

Focus problem when JPopupMenu is shown

I have compiled and ran the following 'JPopupTest.java' in JDK 1.4.1 on Windows. Kindly conduct the two tests as given below
First Test :
============
The class shows an editable JComboBox and a JButton when visible. Now click the down-arrow button of the JComboBox and make the drop-down popup visible. Then click on the "OK" button while the popup is visible. The popup gets hidden and a dialog is displayed as it should be.
Second Test :
=============
Run the appilcation again. This time type something in the editable textfield of the JComboBox. A custom JPopupMenu with the text "Hello World" would be visible. Then click on the "OK" button while the popup is visible. The expected dialog is not shown. The custom JPopupMenu gets hidden. Now click on "OK" button again. The dialog is visible now.
My Desire :
===========
When I click on the "OK" button in the "Second Test" the JPopupMenu should get hidden and the dialog gets displayed (as it happens for the "First Test") in one click.

JPopupMenu ignores setOpaque(false) near screen edges

Dear group
I try to paint a custom JPopupMenu with transparency, but this is ignored when the popup is opened so it overlaps near screen edges (bottom and right side). This is also the case if the popup overlaps the Microsoft Windows toolbar at the bottom.
I may be able to emulate JPopupMenus using custom components in a JLayeredPane, but can anyone explain the above behaviour?
Thanks and Best Regards,
Aksel, Denmark
Environment: j2sdk-se 1.6.0_10 and windows xp
Example:
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Font;
import java.awt.Rectangle;
import java.awt.Toolkit;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPopupMenu;
public class TransparencyPopupNearBorderTest {
public static void main(String[] args) {
final JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLocationRelativeTo(null);
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
frame.setBounds(new Rectangle(screenSize));
frame.setUndecorated(true);
frame.setPreferredSize(screenSize);
frame.addMouseListener(new MouseAdapter() {
@Override
public void mouseReleased(MouseEvent e) {
JPopupMenu popup = new JPopupMenu();
popup.setOpaque(false);
JLabel label = new JLabel("TRANSPARENT");
label.setFont(new Font("Helvetica", Font.PLAIN, 42));
popup.add(label);
popup.setLightWeightPopupEnabled(false);
popup.show(frame, e.getX(), e.getY());
frame.getContentPane().setBackground(Color.BLUE);
frame.pack();
frame.setVisible(true);
}

Don't forget to use the Code Formatting Tags so the posted code retains its original formatting. That is done by selecting the code and then clicking on the "Code" button above the question input area.
I don't know if transparency painting has changed in 1.6.0_10. Prior to that I believe transparency can only be achieved in lightweight components (ie. Swing does all the painting). JFrame, JWindow and JDialog are not lightweight because they use OS components.
In the case of a popup, it is lightweight when entirely contained within its parent frame. But a lightweight popup can not be painted outside the bounds of the frame so a JWindow (I believe) is used as the popup, which can't be transparent.

Disabled components: to popup or not to popup context menu?

Hi experts,
just noticed that Swing pops up a component menu on mouse click even if the component isn't enabled. Seems to contradict the general rule to not allow "active" interaction (vs. "passive" as f.i. still showing the tooltip, the distinction is probably freely invented but serves me well enough ;) with a disabled component.
Could half-way live with that - except that then all menu items need to be disabled individually. Another option would be to return a null componentPopup if disabled. Not generally applicable because requires subclassing. Yet another might be to force-inject a MouseListener into the rootPane: it would intercept and swallow the popup triggers if the target is disabled, otherwise delegate to the ui-installed listener.
Comments please?
Thanks
Jeanette

release is out (here's a screenshot: http://www.jyloo.com/news/?pubId=1297423104000 - commercial, though) - so have a bit more time right now to tackle this
What puzzled me most in your comments was:
>
(and set the show popup action enabled/disabled as well). because I expected that to be not a problem at all: RootPane's action in isEnabled(sender) first checks if the sender is the focusOwner and returns false if not. Disabled components cannot be focusOwner, so safe territory. Except ... they can, even if there are enabled focusable components around. Turns out that the KeyboardFocusManager isn't clever enough to keep transfering the focus when a whole bunch of components is disabled. Or maybe it's a timing issue, as focus transfers can be asynchronous, and/or are tricky anyway, don't know. Whatever, when disabling a bunch of components, it must be done in the inverse order of the focusTransferCycle ... and that's completely unmanageable except for most simple contexts, like focus cycle is the same as insertion order, than reversing disable loop is a brittle option
// before calling this, focus on parent.getComponent(0)
// the natural way of disabling the children
for (Component child: parent.getComponents()) {
     child.setEnabled(false);
// after the call, focus on parent.getComponent(1)
// inversing
for (int i = parent.getComponentCount() - 1; i >= 0; i--) {
   parent.getComponent(i).setEnabled(false);
// focus somewhere elseINCREDIBLE ...
overriding getComponentPopup to return null if disabled (as I did as a quick measure) is not really an option - don't want to override each and every component ;-) Another hook - not clean either, but at least manageable, might be a custom JPopupMenu: subclass and show only if enabled.
@override
public void show(Component invoker, int x, int y) {
    if (!invoker.isEnabled()) return;
    super.show(..)
}This still leaves the action enabled fooled - reports true because the invoker has a componentPopup - but then, a disable comp should be focusOwner anyway.
Cheers

Small issue with custom table cell editor and unwanted table row selection

I'm using a custom table cell editor to display a JTree. Thing i notice is that when i select a value in the tree pop-up, the pop-up closes (as it should) but then every table row, from the editing row to the row behind the pop-up when i selected the value becomes highlighted. I'm thinking this is a focus issue, but it thought i took care of that. To clairfy, look at this: Before . Notice how the "Straightening" tree item is roughly above the "Stock Thickness" table row? When i select Straightening, this is what happens to my table: After .

As I said, you have to have empty context elements before additional rows will be open for input.
For instance if you want to start with 5 rows available for input do the following to your internal table that you will bind:
data itab type standard table of sflight.
do 5 times.
append initial line to itab.
enddo.
context_node->bind_table( itab ).
The other option if you need n number of rows is to add a button to the table toolbar for adding more rows. When this button is pressed, you add a new context element to the node - thereby creating a new empty row in the table.

Overriding double click in JTable custom cell

I have a JTable where I reset the custom cells to become editable on a single click instead if a double using:
((DefaultCellEditor)table.getDefaultEditor(String.class)).setClickCountToStart(1);
Now what I need to do is display a JPopupMenu click a cell is double clicked. This works on cells that are not editable but the problem is that the user needs the popup dialog to display info for the cells that are editable.
I have used the basic way to implement a double click on a certain column (in this case my third column):
public void mouseClicked(MouseEvent e){
 if (e.getClickCount() == 2 && table.getSelectedColumn() == 2 ){
 popupMenu.show( e.getComponent(),
e.getX(), e.getY() );
But when double clicking, nothing happens.
Anyone have any idea to implement this or over-ride an editable cell?
Thanks,
Chris

This still says <identifier> expect, how can I resove this please? Then you still have something wrong with your code. Since you didn't post your code how are we supposed to help?
The proper way to ask a question is to include your demo code that trys to illustrate the problem. Something like the following:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class TableRightClick extends JFrame
 public TableRightClick()
 JTable table = new JTable(10, 5);
 table.addMouseListener( new MouseAdapter()
 public void mousePressed(MouseEvent e)
 if ( SwingUtilities.isRightMouseButton(e) )
// if (e.isPopupTrigger())
 JTable source = (JTable)e.getSource();
 int row = source.rowAtPoint( e.getPoint() );
 int column = source.columnAtPoint( e.getPoint() );
 System.out.println(column);
 source.changeSelection(row, column, false, false);
 table.setPreferredScrollableViewportSize(table.getPreferredSize());
 getContentPane().add( new JScrollPane(table) );
 public static void main(String[] args)
 TableRightClick frame = new TableRightClick();
 frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
 frame.pack();
 frame.setLocationRelativeTo( null );
 frame.setVisible( true );
}

A custom version of JOptionPane.showInputDialog();

I am trying to create a custom input dialog window so that I can have a right click event handler which lets me copy/cut/paste text using the mouse. However, after constructing the following code [as a standalone class, how I plan on using it], I lost the ability to finalize my selection with the 'Enter' key:
class CustomInputDialog {
 public static javax.swing.JLabel lbl;
 public static javax.swing.JTextField txt;
 public static javax.swing.JPopupMenu pop;
 public static String showInputDialog(String message, String guess) {
 lbl = new javax.swing.JLabel(message);
 txt = new javax.swing.JTextField(guess, 10);
 pop = new javax.swing.JPopupMenu();
 javax.swing.Action copyAction = new javax.swing.AbstractAction(javax.swing.text.DefaultEditorKit.copyAction) {
 public void actionPerformed(java.awt.event.ActionEvent e) {
 txt.copy();
 javax.swing.Action cutAction = new javax.swing.AbstractAction(javax.swing.text.DefaultEditorKit.cutAction) {
 public void actionPerformed(java.awt.event.ActionEvent e) {
 txt.cut();
 javax.swing.Action pasteAction = new javax.swing.AbstractAction(javax.swing.text.DefaultEditorKit.pasteAction) {
 public void actionPerformed(java.awt.event.ActionEvent e) {
 txt.paste();
 javax.swing.JMenuItem m1 = new javax.swing.JMenuItem(copyAction);
 javax.swing.JMenuItem m2 = new javax.swing.JMenuItem(cutAction);
 javax.swing.JMenuItem m3 = new javax.swing.JMenuItem(pasteAction);
 m1.setText("Copy"); m2.setText("Cut"); m3.setText("Paste");
 pop.add(m1); pop.add(m2); pop.add(m3);
 txt.setComponentPopupMenu(pop);
 java.awt.Container ct = new java.awt.Container();
 ct.setLayout(new java.awt.GridLayout(2,1));

 int responce = javax.swing.JOptionPane.showOptionDialog(null, ct, "TITLE.", javax.swing.JOptionPane.OK_CANCEL_OPTION, javax.swing.JOptionPane.QUESTION_MESSAGE, null, options, txt);
 if (responce == javax.swing.JOptionPane.OK_OPTION) {
 return txt.getText();
 return null;
}In an attempt to get the enter key working, I separated an instance of the JOptionPane class, so I could refer to it in a keyHandler event using the JTextField. In doing the following code adjustments, now not only does the enter key do nothing, but the method seems to always return null, even if the OK button is selected by the user via mouse:
class CustomInputDialog {
 public static javax.swing.JLabel lbl;
 public static javax.swing.JTextField txt;
 public static javax.swing.JPopupMenu pop;
 public static javax.swing.JOptionPane op;
 public static String showInputDialog(String message, String guess) {
 lbl = new javax.swing.JLabel(message);
 txt = new javax.swing.JTextField(guess, 10);
 pop = new javax.swing.JPopupMenu();
 javax.swing.Action copyAction = new javax.swing.AbstractAction(javax.swing.text.DefaultEditorKit.copyAction) {
 public void actionPerformed(java.awt.event.ActionEvent e) {
 txt.copy();
 javax.swing.Action cutAction = new javax.swing.AbstractAction(javax.swing.text.DefaultEditorKit.cutAction) {
 public void actionPerformed(java.awt.event.ActionEvent e) {
 txt.cut();
 javax.swing.Action pasteAction = new javax.swing.AbstractAction(javax.swing.text.DefaultEditorKit.pasteAction) {
 public void actionPerformed(java.awt.event.ActionEvent e) {
 txt.paste();
 javax.swing.JMenuItem m1 = new javax.swing.JMenuItem(copyAction);
 javax.swing.JMenuItem m2 = new javax.swing.JMenuItem(cutAction);
 javax.swing.JMenuItem m3 = new javax.swing.JMenuItem(pasteAction);
 m1.setText("Copy"); m2.setText("Cut"); m3.setText("Paste");
 pop.add(m1); pop.add(m2); pop.add(m3);
 txt.setComponentPopupMenu(pop);
 txt.addKeyListener(new java.awt.event.KeyListener() {
 @Override public void keyTyped(java.awt.event.KeyEvent e) {}
 @Override public void keyReleased(java.awt.event.KeyEvent e) {}
 @Override public void keyPressed(java.awt.event.KeyEvent e) {
 if (e.getKeyCode() == java.awt.event.KeyEvent.VK_ENTER) {
 op.setInitialValue(javax.swing.JOptionPane.OK_OPTION);
 op.selectInitialValue();
 java.awt.Container ct = new java.awt.Container();
 ct.setLayout(new java.awt.GridLayout(2,1));
 ct.add(lbl); ct.add(txt); txt.selectAll();
 Object[] options = {"OK", "Cancel"};
 op = new javax.swing.JOptionPane(ct, javax.swing.JOptionPane.QUESTION_MESSAGE, javax.swing.JOptionPane.OK_CANCEL_OPTION, null, options, txt);
 op.createDialog(null, "TITLE.").setVisible(true);
 int returnValue = (op.getValue() instanceof Integer) ? ((Integer)op.getValue()).intValue() : javax.swing.JOptionPane.CANCEL_OPTION;
 if (returnValue == javax.swing.JOptionPane.OK_OPTION) {
 return txt.getText();
 return null;
}I've been going through the javax.swing references on the APIs, but I cannot find anything that seems to make sense to me as to a way to work towards the solution, if anyone could give me some help or guidance, it would be much appreciated. Thanks!
Ps: I think the issue may be in "returnValue" getting set to JOptionPane.CANCEL_OPTION as it is being executed before the JOptionPane dialog is finally closed and a value is entered. However, on the examples I was looking at, it didn't seem like there was an onClosed event handler or something similar used.
Pps [note]: I originally posted this in the Java Programming area, and was directed to come here. Original Post: [http://forums.sun.com/thread.jspa?threadID=5445202|http://forums.sun.com/thread.jspa?threadID=5445202].

EDIT: I finally was able to get everything working the way I want it. Thanks for everyone's help. If anyone would like to use my code in the future, I'll attach it to this post. Note: For new lines, I had to use the <html> tag at the start of the msg and tags for new lines instead of using the \r\n characters.

Resize JComboBox dropdown doesn't work without customized ListCellRenderer

Based on the forum thread Horizontal scrollbar for JComboBox across multiple look and feel , the following code will work, if only I provide a customized ListCellRenderer (A JPanel with several JLabels).
FYI, here is my ListCellRenderer code [http://jstock.cvs.sourceforge.net/viewvc/jstock/jstock/src/org/yccheok/jstock/gui/ResultSetCellRenderer.java?view=markup]
Here is the code which adjust the drop down list width. The setup instruction is exactly same as the one mentioned in forum by Kleopatra
 private void adjustPopupWidth() {
 if (this.getItemCount() == 0) return;
 Object comp = this.getUI().getAccessibleChild(this, 0);
 if (!(comp instanceof JPopupMenu)) {
 return;
 JPopupMenu popup = (JPopupMenu) comp;
 JScrollPane scrollPane = (JScrollPane) popup.getComponent(0);
 Object value = this.getItemAt(0);
 Component rendererComp = this.getRenderer().getListCellRendererComponent(null, value, 0, false, false);
 if (rendererComp instanceof JXTable) {
 scrollPane.setColumnHeaderView(((JTable) rendererComp).getTableHeader());
 Dimension prefSize = rendererComp.getPreferredSize();
 Dimension size = scrollPane.getPreferredSize();
 size.width = Math.max(size.width, prefSize.width);
 scrollPane.setPreferredSize(size);
 scrollPane.setMaximumSize(size);
 scrollPane.revalidate();
 }However, when come to a JComboBox, without explicitly provided it a list cell renderer, the above code will have NPE being thrown at line
 Component rendererComp = this.getRenderer().getListCellRendererComponent(null, value, 0, false, false);
 // Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
 // at javax.swing.plaf.basic.BasicComboBoxRenderer.getListCellRendererComponent(BasicComboBoxRenderer.java:94)Hence, I modify the code as follow and hoping it will work.
 private void adjustPopupWidth() {
 if (this.getItemCount() == 0) return;
 Object comp = this.getUI().getAccessibleChild(this, 0);
 if (!(comp instanceof JPopupMenu)) {
 return;
 JPopupMenu popup = (JPopupMenu) comp;
 JScrollPane scrollPane = (JScrollPane) popup.getComponent(0);
 Object value = this.getItemAt(0);
 //Component rendererComp = this.getRenderer().getListCellRendererComponent(null, value, 0, false, false);
 Component rendererComp = this.getRenderer().getListCellRendererComponent((JList)scrollPane.getViewport().getView(), value, 0, false, false);
 if (rendererComp instanceof JXTable) {
 scrollPane.setColumnHeaderView(((JTable) rendererComp).getTableHeader());
 Dimension prefSize = rendererComp.getPreferredSize();
 Dimension size = scrollPane.getPreferredSize();
 size.width = Math.max(size.width, prefSize.width);
 scrollPane.setPreferredSize(size);
 scrollPane.setMaximumSize(size);
 scrollPane.revalidate();
 }No more exception being thrown this time. Just that my dropdown list doesn't resize at all when I have a long String. It remains normal size as usual, with horizontal scrollbar being shown to catter the long String.
Is there anything I had missed out?
Thanks

Yes. The problem solved. Out of curiosity, is it necessary to have statement? As I remove it, it just work as well.
scrollPane.revalidate();I include SSCCE for this problem.

Custom JComboBox -- MouseListener

Hi. I'm in the process of making a custom JComboBox (called TitledComboBox).
It's going to use a ComboBox as the component that is always visible, but when you click it instead of the standard dropdown, I'm creating a JPopupMenu to replace that. That way I want to avoid the first element (or the selected one) being repeated inside the list.
So I've created my class extending JComboBox, and implemented MouseListener, but I'm unable to make the listener work for the JComboBox layout manager. It works perfectly for the spots on the JComboBox where the LayoutManager doesnt paint (or whatever it does), so the "arrow" doesn't effect the MouseListener....
How can I extend the default JComboBox LayoutManager to have the same MouseListener??

package gui;
import java.awt.Color;
import java.awt.Component;
import java.awt.Graphics;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.*;
@SuppressWarnings("serial")
public class TitledComboBox extends JComboBox implements MouseListener
 @SuppressWarnings("serial")
 private class PopItem extends JMenuItem
 public PopItem(String text)
 setLayout(null);
 setText(text);
 setOpaque(false);
 setBackground(Color.BLACK);
 public void paint(Graphics g)
 super.paint(g);
 @SuppressWarnings("serial")
 private class PopMenu extends JPopupMenu
 public PopMenu()
 this.setLayout(null);
 this.setPopupSize(120, 23*this.getComponentCount());
 this.setOpaque(false);
 public PopMenu(String[] items)
 this();
 for(int i = 0; i < items.length; i++)
 this.add(new PopItem(items));
 updateSize();
 private void updateSize()
 this.setPopupSize(120, 23*this.getComponentCount());
 public void show(Component arg0, int arg1, int arg2)
 super.show(arg0, arg1, arg2);
 this.setVisible(true);
 public void paint(Graphics g)
 super.paint(g);
 public PopMenu dropdown;
 private TitledComboBox()
 super();
 this.addMouseListener(this);
 this.setVisible(true);
this.setEnabled(false);
 public TitledComboBox(String title)
 this();
 this.addItem(title);
 dropdown = new PopMenu();
 public TitledComboBox(String title, String[] items)
 this();
 this.addItem(title);
 dropdown = new PopMenu(items);
 public void addPopItem(String item)
 dropdown.add(new PopItem(item));
 dropdown.updateSize();
 public void removePopItem(int itemIndex)
 dropdown.remove(itemIndex);
 dropdown.updateSize();
 public void paint(Graphics g)
 this.setEnabled(true);
 super.paint(g);
 this.setEnabled(false);
 public void mouseClicked(MouseEvent m)
dropdown.show(this, 0, 20);
 public void mouseEntered(MouseEvent arg0)
 public void mouseExited(MouseEvent arg0)
 public void mousePressed(MouseEvent arg0)
 public void mouseReleased(MouseEvent arg0)
Using this now gives something very similar to a JComboBox, just without the top element showing. However, I STILL don't know how to get the LayoutManager to be a part of the MouseListener... Please help!

Implementing a dynamic Scrollable JPopupMenu

Hi,
I wanna make a scrollable JPopupMenu. What I am looking for is I am making a custom popup Menu which extends JPopupMenu. I would be overriding the add method.
I dont want to add a list or a combo box to my JPopupMenu. I want to change the layout itself .. i.e. there is a function in the Container.class which gets called when we try to add a menuitem dynamically to the JPopupMenu
Function Name:
protected void addImpl(Component comp, Object constraints, int index)Snippet which i am looking in the function
if (layoutMgr instanceof LayoutManager2) {
((LayoutManager2)layoutMgr).addLayoutComponent(comp, constraints);
 }Is there a way while addiing menu items dynamically that I can set the layout to scrollable and hence the menuitems when added are in a scrollpane automatically.. Hence I what i get also is a Scrollable JPopupMenu

well, this is implementation of PopupMenu with scroll
import java.awt.Component;

 public ScrollPopupMenu(GraphicsConfiguration gc) {
 super();
 scroll = new JScrollPane();
 panelMenus = new JPanel();
 panelMenus.setLayout(new GridLayout(0,1));
 scroll.setViewportView(panelMenus);
 scroll.setBorder(null);
 scroll.setMaximumSize(new Dimension(scroll.getMaximumSize().width,
 this.getToolkit().getScreenSize().height -
 this.getToolkit().getScreenInsets(gc).top -
 this.getToolkit().getScreenInsets(gc).bottom - 4));
 super.add(scroll);
 public void show(Component invoker, int x, int y) {
 this.pack();
 panelMenus.validate();
 int maxsize = scroll.getMaximumSize().height;
 int realsize = panelMenus.getPreferredSize().height;
 int sizescroll = 0;
 if (maxsize < realsize) {
 sizescroll = scroll.getVerticalScrollBar().getPreferredSize().width;
 scroll.setPreferredSize(new Dimension(
 scroll.getPreferredSize().width + sizescroll,
 scroll.getPreferredSize().height));
 super.show(invoker, x, y);
 public void add(JButton menuItem) {

We had a requirement to retrieve "aging of receiveables" by customer. Basically, it goes thru each record and depending on the due date places the amounts in the following buckets (example). 0-30 day Overdue, 31-60 days Overdue, 61-90 days overdue, 30+ days overdue, 60+ days overdue) etc all the way to 6+ years overdue.
There are also cooresponding buckets for coming due analysis. For example, what is: 0-30 days coming due, 31-60 days coming due, 30+ days coming due, etc...
To do this, first I needed to be able be able to produce an open items statement at any given time in the past. Now, this seems impossible because of how the items go from open to cleared all the time. And an item that was open one month ago, may not be open anymore.
What I did was first remove any selections on item status. Then compare the posting date with teh key date in the past, if the posting date is less than or equal to the key date, keep the record.
Then compare the clearing date with the key date. First, keep all that are #. (This keeps all records still open from that posting date/key date)
Then, add another check for all items that were cleared after the key date (GT Key Date). This gives you the open items on that date.
Hope that makes sense. Let me know if you want clarification.

Error in creation of custom PD infotype

Hi,
I have a task of creating a custom PD infotype(p9xxx). I created HRI9xxx structure with all the custom fields and when I try to create the infotype using tcode PPCI(selected 'field infotype' option and create button in the 'infotype' block was pressed), it gives an error message that p9xxx-begda is not in ABAP dictionary and then it gives me list of screens, module pools and tables created. This custom infotype entry does not exist in T777I. I have tried regenerating it and same problem persists. If anyone knows the solution, please do let me know.
Thanks in advance

Implementing BADI MD_ADD_COL_EZPS for MD04 custom column

Hi there,
I'm using BADI MD_ADD_COL_EZPS to display 3 new buttons and three new columns in MD04.
For each line item that is displayed, the custom column is filled, after the button is hit -This works fine.
My Question is:
Is there any way to limit the value that is filled into the new column so that it only appears on the FIRST line item/row?
(At the moment it is repeated all the way down the page - the new value is a material characteristic, so doesn't change, will always be the same for each line)
I've looked at all the available structures/tables in the FILL_ADD_COLUMNS method of the BADI, and none seem suitable
to determine the "first" row. (ie. something like the way SY-TABIX or SY-INDEX might be used)
Any help appreciated.
Thanks,
David.

Hi Shubhendu,
in the method 'ACTIVATE_ADD_COLUMNS', you can set the flag EZ1_MODE to '1' to make the first column visible always. (it's been a while, but I think setting it to '2' makes it visible when the button is pressed.)
Same applies to EZ2_MODE for second column, EZ3_MODE for third.
look at the flags/parameters in this method, and also in FILL_ADD_COLUMNS, to fill the data.
here you need to fill structure EMDEZX_USEX1 (for column 1) etc.
The code is hit for each record displayed in MD04
Hopefully this helps you.
Regards,
David
