If you mean applet size as displayed on a web page, simply change the HTML invoking the applet.

Can we change the bound location of an operator using OMB?

Hi,
I'm trying to change the location of an table operator using the following code:
OMBALTER MAPPING 'MAP_NAME' MODIFY OPERATOR 'TABLE_TEST' SET PROPERTIES (database_link) VALUES ('PROJECT1/SOURCE1/TEMP_TABLE3')
OMBCOMMIT
OMBPlus tells me that the command ran successfully. But if i take a look on the design center, the change didn't occur. The old location for the operator remains.
Am i using the right property type? database_link?
Thank You!
Filipe

What you've run only change the link location. It doesn't change the bound location.
I've write an OMB scripts to automate the changing of bound location within different project .

Changing the bounding box size

When I go to print an image in Photoshop CC, a dialogue box appears and on the left-hand side is the image to be printed. Bordering the image are small diagonal lines which I'm assuming are the bounding box. The distance between the edge of the page varies from side to side and I want to center the photo. I can't see how to do that.
Thanks.

The print dialog preview area show basically three areas. The Paper size the printer is set to and the sizes are displayed with numeric unites. If you see small diagonal lines these are showing the areas the printer can not print on with the current settings. With different printer setting this area may change for example if the printer support borderless the side non printable may go way but there still be some top and bottom non printable area. The Bottom non printable area may go away if you switch from sheet feed to roll paper feed. Inside the diagonal line is the printable area and inside that a bounding box of the image. If You check scale for media the image will be scaled to fit within the print area.

Is it possible to change the bounds of a progressBar? (to a different shape

I want to draw the shape of a battery, and use it as a progress bar. Now I know I can do this from scratch, and I have done a test case, but it simply doesn't look as good as the JProgressBar does.
I have tried reading the JProgressBar class, to see where it draws the rect, and copy the class, only make it fill a <code>Shape</code> but I haven't had any luck.
anyone have any ideas?

I'm not sure I completely understand your response...what do you mean by aspect? also don't or cant?

Hyperlink panel disabled - So how do I change the appearance of a hyperlink?

I am at the final stages of layout and the only thing preventing me from publishing electronically is that the hyperlinks have bounding boxes around them. I have previously been able to use the hyperlink options to change the appearance of a hyperlink but my panel is completely greyed out > see below. I can only change the destination and that does not give any link options. The panel doesn't even register any hyperlinks although you can see many in my screen grab alone. I have modified the character style but since these are active links (which should remain active), the style does not change the bounding box. I even tried retyping links and linking them to their URL with InDesign but I cannot control any options after a link has been made. I also cannot afford to do this +100 times. Anyone have any tips? I'm using CS6 on a MacBook Pro. I've already rebooted the computer and InDesign to no avail. Am I doing something wrong? Is there a script I can use?
Thanks to anyone who can help!

Change AutoScroll Bounds in JTextPane

I cannot figure this out for the life of me. I would like to CHANGE the bounds for the autoscroll on a JTextPane that resides inside a JScrollPane when the user selects text and moves the mouse outside of the "autoscroll bounds".
The normal bounds for scrolling down a JTextPane (when inside a JScrollPane) are usually the bounds of the JTextPane itself. (You can verify this with my example by selecting some text with the mouse button held down, and moving your cursor outside the bottom of the window). I would like to move the bottom bounds up higher into the window (indicated by the black line that resides on the glasspane).
I have provided this example to use as a starting point. It doesn't do anything of use right now. I have tried about 20 things, but things have gotten so messed up, and the level of internal code that I started to mess around with got way over my head... so I'm just going to post this with a clean start, and hopefully we can move in a positive direction. I will relay my findings about a paticular route if we start moving down one i've already failed at.
Thanks for you time.

Can you change the colour of an 'image' bounding box?

This concerns bounding boxes not 'strokes'.
Is it possible to customise the default colour of a bounding box around an image?
I know that the default 'rectangle image frame' matches the Layer colour (eg: Layer 1 - Light Blue, with an the image bounded by a brown box) which is easily changed by moving it to another layer (eg: Layer 2 - Red, which displays an image bounding box of Cyan). What defines the colour of the bounding box of an image that is placed inside the 'rectangle image frame' and can it be changed?
I have no real necessity to change it, I just wondered if it was possible?
Steve

I'm not sure you understand the terminology.
The bounding box is an imaginary rectangle that encloses the shape of an object or group of objects. For a simple graphics frame this is the same size and shape as the frame and is poisitioned on the frame edge (and it's what you see when you select the frame). The bounding box is used for calculating object positioning. When dispalyed, it takes on the color assigned to the layer.
The frame edge is also fictitious. It's a screen display aid that can be tuned on or off to help you locate objects and also uses the color assigned to the layer. It corresponds to the path that describes the edge of the frame, so might not be rectangular (a bounding box is always rectangular).
The stroke is an attribute assigned to the path describing the perimeter of a closed object or the path itself of an open path. Stokes can be assigned a weight, color, and stroke style such as dotted or striped.
An image placed inside a frame has it's own bounding box, but not a frame edge or stroke. To see the image bounding box use the direct select tool to select the image inside the frame. If you crop an image so it is larger than the containing frame, or or enlarge the frame so the image does not completely fill it, you can see the differnce between the bounding boxes very easily. The color of the image bounding box is also tied to the layer color and is not editable by the user.

Preserving a field's value on changing the field access parameter?

I have a form that has a number of fields that are set to "protected" and have calculation scripts on them. If the user selects a specific radio button option elsewhere, the form sets the .access parameter to "open" and disables the calculation so that the user can enter whatever they want into those fields. The problem arises when the user imports XML data via Acrobat. The radio button choice is made (since it is bound to an element in the schema), but when the form changes the access parameter of the fields to "open", it fires the calculate event on the fields and we lose the value assigned to those fields from the imported XML.
Is there any way to preserve the fields value when it changes from "protected" to "open"? Here is an example PDF w/ XSD.
The more I dig into this the more I think this might be an issue with calculate.override not disabling the calculations on a field, even when it is set to "open" - at least until the user manually edits that field.

Ok, worked out a solution. It's specific to my application, but maybe someone else will get something out of it. What I did is moved the calculation script from the field I am changing the access parameter of (call it "Field A") to the fields that feed into that field (call them "Field B" and "Field C"). Now, when the user triggers the exit events on B and C, each one fires a script that updates the value of A. For my application, this works only because B and C are hidden from the use if they toggle the radio button allowing them to manually enter A.
Basically, instead of A pulling values from B and C to calculate it's value, B and C check each other and push values to A.

How to proceed with a requirement on changing the input type

I have a requirement that seems rather simple yet I am having a hard time achieving it. What I have is a table where there is a Data_Value field and a Data_Type field. The Data_Value is stored in the database as a VARCHAR2(100) and the Data_Type contains the following values: STRING, DATE, DATETIME, NUMBER.
The page I am working on is an update page, and what I am hoping to achieve through PPR is that whenever the user changes the Data_Type (I have these in a messageChoice) that the Data_Value will then be rendered with the correct settings.
Originally I thought that I could just programmetically change the DataType property in the messageTextInput I am using, but this was causing errors since I had it bound to that field in the view which is a Varchar. I then thought that I could create one field of each type and render the one I want based on the selection, but I am getting an error saying: Data Type - Attribute set for DataType in view object Xo2cCustAcctUpdateVO1 failed whenever a new value is picked from my picklist.
Does anyone have some suggestions on how I should tackle this issue? As a last resort I thought about just leaving that field as a String (which is how it is stored anyway) and do some validation in my controller to ensure it is formatted correctly.
Thanks,
Greg

Greg,
The simplest approach would be to define one field per data type and toggle them based on the data type selected from the choice bean. Use SPEL and PPR.

Getting the bounds of a drawn image on a panel

Hello, I have a problem with getting the bounds of a drawn image on a panel...Since it is drawn as graphics, i tried getClipBounds and since my class extends JPanel i tried to get the bounds from the panel but neither of them worked properly. It only gets the bounds of a jframe that contains the panel.Then i tried to put the panel in a layeredpane and then a container; but this time the image disappeared completely. Hope someone can help or tell me what I am doing wrong. Thanks in advance. Here is the code below:
By the way what I am trying to do in this code is basically zooming the image in and out by dragging or the mouse wheel. But I need to get the bounds so that I can use this.

You'll need a stable point in the component to track and orient to the scaling transform(s).
From this you can construct whatever you need in the way of image location and size.
Let's try a center–of–image tracking point:

 Point2D.Double origin = new Point2D.Double(0,0);
 public ZD(BufferedImage image) {
 this.image = image;
 center = new Point(image.getWidth()/2, image.getHeight()/2);
 protected void paintComponent(Graphics g) {
 super.paintComponent(g);
 Graphics2D g2 = (Graphics2D)g;
 g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION,

 g2.drawRenderedImage(image, at);
 g2.setPaint(Color.red);
 g2.fill(new Ellipse2D.Double(origin.x-1.5, origin.y-1.5, 4, 4));
 g2.setPaint(Color.blue);
 g2.fill(new Ellipse2D.Double(center.x-1.5, center.y-1.5, 4, 4));
 private void setTransform(double scale) {
 // keep image centered over Point "center"
 double x = center.x - scale*image.getWidth()/2;

 origin.setLocation(x, y);
 at.setToTranslation(x, y);
 at.scale(scale, scale);

How can i change the column label text in a alv table display

how can i change the column label text in a alv table display??
A similar kinda of question was posted previuosly where the requirement was the label text was needed and following below code was given as solution :
* declare column, settings, header object
DATA: lr_column TYPE REF TO cl_salv_wd_column.
DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings.
DATA: lr_column_header type ref to CL_SALV_WD_COLUMN_HEADER.
get column by specifying column name.
lr_column = lr_column_settings->get_column( 'COLUMN_NAME1' ).
set Header Text as null
lr_column_header = lr_column->get_header( ).
lr_column_header->set_text( ' ' ).
My specific requirement is i have an input field on the screen and i want reflect that value as the column label for one of the column in the alv table. I have used he above code with slight modification in the MODIFYVIEW method of the view since it is a process after input. The component gets activated without any errors but while run time i get an error stating
"The following error text was processed in the system CDV : Access via 'NULL' object reference not possible."
i have checked in debugging and the error occured at the statement :
lr_column = lr_column_settings->get_column( 'CURRENT_YEAR' ).Please can you provide me an alternative for my requirement or correct me if i have done it wrong.
Thanks,
Suri

I found it myself how to do it. The error says that it is not able to find the reference object i.e it is asking us to refer to the table. The following piece of code will solve this problem. Have to implement this in WDDOMODIFYVIEW method of the view. This thing works comrades enjoy...
DATA : lr_cmp_usage TYPE REF TO if_wd_component_usage,
 lr_if_controller TYPE REF TO iwci_salv_wd_table,
 lr_cmdl TYPE REF TO cl_salv_wd_config_table,
 lr_col TYPE REF TO cl_salv_wd_column.
DATA : node_year TYPE REF TO if_wd_context_node,
 elem_year TYPE REF TO if_wd_context_element,
 stru_year TYPE if_alv_layout=>element_importing,
 item_year LIKE stru_year-i_current_year,
 lf_string TYPE char(x),
DATA: lr_column TYPE REF TO cl_salv_wd_column.
DATA: lr_column_header TYPE REF TO cl_salv_wd_column_header.
DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings.
Get the entered value from the input field of the screen
node_year = wd_context->get_child_node( name = 'IMPORTING_NODE' ).
elem_year = node_year->get_element( ).
elem_year->get_attribute(
 EXPORTING
 name = 'IMPORT_NODE-PARAMETER'
 IMPORTING
 value = L_IMPORT_PARAM ).
WRITE L_IMPORT_PARAM TO lf_string.
Get the reference of the table
lr_cmp_usage = wd_this->wd_cpuse_alv( ).
IF lr_cmp_usage->has_active_component( ) IS INITIAL.
 lr_cmp_usage->create_component( ).
ENDIF.
lr_if_controller = wd_this->wd_cpifc_alv( ).
lr_column_settings = lr_if_controller->get_model( ).
get column by specifying column name.
IF lr_column_settings IS BOUND.
 lr_column = lr_column_settings->get_column( 'COLUMN_NAME').
set Header Text as null
 lr_column_header = lr_column->get_header( ).
 lr_column_header->set_text( lf_string ).
endif.

How to get the bound object of an external table with OMB

Hello,
I try to find it but without success. So may be one of you, know this secret information.
I want to synchronize with the help of an OMB script my external tables.
OMBSYNCHRONIZE FLAT_FILE '/MY_PROJECT/MY_FLAT_FILE_MODULE/MY_FLAT_FILE' RECORD 'MY_RECORD' TO EXTERNAL_TABLE 'MY_EXTERNAL_TABLE' \
USE (RECONCILE_STRATEGY 'REPLACE', MATCHING_STRATEGY 'MATCH_BY_OBJECT_ID')For this purpose, I need to know the bound object. When you synchronize with the help of the GUI, you see it easily.
Example:
/MY_PROJECT/MY_FLAT_FILE_MODULE/MY_FLAT_FILE/MY_RECORDI searched in the properties of the external table and I don't see a BOUND OBJECT property.

Change get the location by get the flat_file_module

Yes, Oleg. It's what's worried me.

How do I move an object from one photo to another and then change the scene, i.e. winter to sum?

How do I move an object from one photo to another and then change the scene, i.e. winter to summer?

OK.
Open the picture with the new scene. This will be your canvas.
Open the picture with object A, select it with one of the selection tools, go to Edit>copy
Go back to the new scene/canvas, Go to Edit>paste
Repeat for object B
Use the move tool to position A & B, each on its own layer. Use the corner handles of the bounding box to resize, if necessary
You should have 3 layers: Background layer, and the 2 layers with A & B
Note: It's best if the resolution of the 3 picture files is the same value.

Changing the size of a JComboBox

Greetings,
I am trying to build a mechanism to perform zooming on a JPanel with an arbitrary collection of components (including nested JPanels). I've tried a number of things with little success. The following is my most promising contraption. It can zoom labels, textfields, checkboxes, and buttons. However, for some reason, the combo box refuses to accept a changes to its size. I'm not sure why this is the case. Its font changes size appropriately.
Anyway, I'm running in JDK 1.4, and the following program lays out a palette of components. To change the size of the components, hit F1 to zoom in, and F2 to zoom out.
import java.awt.Component;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.Font;
import java.awt.KeyEventPostProcessor;
import java.awt.KeyboardFocusManager;
import java.awt.event.KeyEvent;
import java.awt.geom.AffineTransform;
import javax.swing.JButton;
import javax.swing.JCheckBox;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
public class Demo extends JPanel
 public class Zoomer
 private double m_zoom = 1;
 private JPanel m_panel;
 public Zoomer(JPanel panel)
 m_panel = panel;
 private AffineTransform getTransform()
 return AffineTransform.getScaleInstance(m_zoom, m_zoom);
 private Font transform(Font font)
 return font.deriveFont(getTransform());
 private Dimension transform(Dimension dimension)
 Dimension retval = new Dimension();
 retval.setSize(dimension.getWidth() * m_zoom, dimension.getHeight() * m_zoom);
 return retval;
 private void performZoom(Container container)
 Component[] components = container.getComponents();
 for(int i = 0; i < components.length; i++)
 Component component = (Component)components;
component.setFont(transform(component.getFont()));
component.setSize(transform(component.getSize()));
for(int i = 0; i < components.length; i++)
Component component = components[i];
if(component instanceof Container)
performZoom((Container)component);
public double getZoom()
return m_zoom;
public void setZoom(double zoom)
if(zoom > 8.0 || zoom < 0.125) return;
m_zoom = zoom;
performZoom(m_panel);
public void zoom(double factor)
setZoom(getZoom() * factor);
public Demo()
JPanel panel = new JPanel();
panel.add(buildPanel());
panel.add(buildPanel());
final Zoomer zoomer = new Zoomer(panel);
add(panel);
KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventPostProcessor(new KeyEventPostProcessor()
public boolean postProcessKeyEvent(KeyEvent e)
if(e.getID() != KeyEvent.KEY_PRESSED) return false;
if(e.getKeyCode() == KeyEvent.VK_F1)
zoomer.zoom(1.2);
if(e.getKeyCode() == KeyEvent.VK_F2)
zoomer.zoom(1/1.2);
return false;
private JPanel buildPanel()
JPanel panel = new JPanel();
panel.add(new JLabel("label: "));
panel.add(new JTextField("Hello World"));
panel.add(new JCheckBox("checkbox"));
panel.add(new JComboBox(new String[] { "Bread", "Milk", "Butter" }));
panel.add(new JButton("Hit Me!"));
return panel;
* Create the GUI and show it. For thread safety, this method should be
* invoked from the event-dispatching thread.
private static void createAndShowGUI()
// Create and set up the window.
JFrame frame = new JFrame("Demo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
// Create and set up the content pane.
Demo newContentPane = new Demo();
newContentPane.setOpaque(true); // content panes must be opaque
frame.setContentPane(newContentPane);
// Display the window.
frame.pack();
frame.setVisible(true);
public static void main(String[] args)
// Schedule a job for the event-dispatching thread:
// creating and showing this application's GUI.
javax.swing.SwingUtilities.invokeLater(new Runnable()
public void run()
createAndShowGUI();

component.setSize(transform(component.getSize()));First of all the above line is not needed. The LayoutManager will determine the bounds (size and location) of each component in the container based on the rules of the LayoutManager. The Flow Layout is the default layout manager for a panel and it simply uses the preferred size of the component as the size of the component.
So what happens is that when you change the font of the component you are changing the preferred size of the component.
So why doesn't the combo box work? Well I took a look at the preferred size calculation of the combo box (from the BasicComboBoxUI) and it actually caches the preferred size. The combo box uses a renderer, so the value is cached for performance one would assume. The method does recalculate the size when certain properties change. Note the isDisplaySizeDirty flag used in the code below:
 else if (propertyName.equals("prototypeDisplayValue")) {
 isMinimumSizeDirty = true;
 isDisplaySizeDirty = true;
 comboBox.revalidate();
 else if (propertyName.equals("renderer")) {
 isMinimumSizeDirty = true;
 isDisplaySizeDirty = true;
 comboBox.revalidate();
 }It also handles a Font property change as well:
 else if ( propertyName.equals( "font" ) ) {
 listBox.setFont( comboBox.getFont() );
 if ( editor != null ) {
 editor.setFont( comboBox.getFont() );
 isMinimumSizeDirty = true;
 comboBox.validate();
 }but notice that the isDisplaySizeDirty flag is missing. This would seem to be a bug (but I don't know why two flags are required).
Anyway, the following change to your code seems to work:
// component.setSize(transform(component.getSize()));
if (component instanceof JComponent)
 ((JComponent)component).updateUI();
}

Changing the bounds....
