JTabbedPane,JTable in JPopupMenu

Hai,
In my applet, I have added JTabbedPane and JTable in JPopupmenu just like JPanel using Java 1.3. It works fine. Now when I run this applet using Java 1.5 plugin, if I click on that JTable or JTabbedPane over JPopupmenu it closed automatically. It works fine in Java 1.4 also.
Any ideas...?

Hai,
Finally I got solution for this. If I use
show(Component invoker, int x, int y) method it gives problem. So
I have changed my code using setLocation(int x,int x) and then
setVisible(true). It works fine.
But Now I have got another problem. If I add JTextField over JPopupMenu, I couldn't edit that textfield.
Anybody having solution for this?

JTable And JPopupMenu

Hello, In a JTable i want when the user press the right button of the mouse to chose an action on JPopupMenu it automaticly select the row where the Press The Right Button.

In your MouseListener you use table.getRowAtPoint(...) to get the row, then you can use table.setRowSelectionInverval(...) to select the row.

Jtable in Jpopupmenu

is it posoble to put a table in a jpopupmenu?

no.well, it is possible, but...
why on earth would one want to do a thing like this!exactly....
Actually, in 1.5, support for any components other than MenuElement implementations is broken - at least with regard to mouse events, which is pretty important. But in 1.4, I believe this would work fine.

Java Package/Class Dependency

Hi, friends,
I would like to get a list of packages that a given package depends on. If it is possible, I would also know which class of the given package depends on which classes.
Is there any software to do this?
If I would like to write a Java utility for that purpose, how can I proceed?
Best regards,
Youbin

in the HTML fles of the java doc, you can know the class hierarchy and antecedents of each class. For example, class JComponent :
java.lang.Object
|
--java.awt.Component
|
--java.awt.Container
|
--javax.swing.JComponent
Moreover, the java doc also show the inner classes, fields and methods inherited from those super classes...
you may also know which classes extends this one. For example JComponent :
All Implemented Interfaces:
ImageObserver, MenuContainer, Serializable
Direct Known Subclasses:
AbstractButton, BasicInternalFrameTitlePane, Box, Box.Filler, JColorChooser,
JComboBox, JFileChooser, JInternalFrame, JInternalFrame.JDesktopIcon, JLabel,
JLayeredPane, JList, JMenuBar, JOptionPane, JPanel, JPopupMenu, JProgressBar,
JRootPane, JScrollBar, JScrollPane, JSeparator, JSlider, JSpinner, JSplitPane,
JTabbedPane, JTable, JTableHeader, JTextComponent, JToolBar, JToolTip, JTree,
JViewport

Converting Swing to Applets

Hello
I have a swing GUI and my employer asked me to convert the whole thing into applets. I just wonder if there is a simpler way of doing it. My GUI now contains only basic swing components like JTabbedPane, JTable etc...,
Thanks.

There may also be resource and security issues associated with the conversion. On the whole modifying the entry point is fairly simple ... convert to JApplet, make sure you have an init method to replace the main method as your entry point. You will need HTML to start the applet.

Resize JTable in JTabbedPane

Given the FileTableDemo from the Java Foundation Class in a Nutshell book.(O'Reilly) Chapter 3 page 51 in my addition.
I have modified the example to place the JTable in a JTabbedPane. Now when the window (JFrame) is resized by the user the JTable no longer resizes. How do I passing the "resizing" into the component (JTable) placed in the JTabbedPane?
Here is the code: My deviation from the example is enclosed in "///////////KBS" and of course the line frame.getContentPane().add(myTP, "Center"); where "pane" has been replaced with "myTP"
Thanks Brad

else
dir = new File(System.getProperty("user.home"));
// Create a TableModel object to represent the contents of the directory
FileTableModel model = new FileTableModel(dir);
// Create a JTable and tell it to display our model
JTable table = new JTable(model);
JScrollPane pane = new JScrollPane(table);
pane.setBorder(BorderFactory.createEmptyBorder(60,20,20,20));
////////KBS

}

Well, I didn't find an answer but I did find a solution.
The JPanel is the problem. I use it to help with layout which is not obvious in this example.
As you can see in the code the JTable is placed in a JScrollPane which is place in a JPanel which is placed in a JTabbedPane.
If I use Box instead of JPanel the JTable in the JScrollPane in the Box in the TabbedPane in the JFrame resizes correclty.
So although JPanel is resizable with setSize it does not get resized when it's JFrame gets resized.
I would still like to know why?
////////KBS
JTabbedPane myTP = new JTabbedPane();
Box myOne = Box.createHorizontalBox();
Box myTwo = Box.createHorizontalBox();
myOne.add(pane);
myTP.add("One", myOne);

Issue with re-sizing JTable Headers, JTabbedPane and JSplit pane

Ok, hopefully I'll explain this well enough.
In my Swing application I have a split pane, on the left hand side is a JTable and on the right hand is a JTabbedPane. In the tabs of the JTabbedPane there are other JTables.
In order to make the rows in the JTable on the left and the JTable(s) on the right line up, the Table Header of all the tables is set to the size of the tallest (deepest?) table header.
Hopefully so far I'm making sense. Now to get to the issue. One of the tables has a number of columns equal to the value on a NumberSpinner (it represents a number of weeks). When this value is changed the table is modified so that it contains the correct number of columns. As the table is re-drawn the table header goes back to its default size so I call my header-resize method to ensure it lines up.
The problem is this: if I change the number of weeks when selecting a tab other than the one containing my table then everything is fine, the table header is re-sized and everything lines up. If I change the number of weeks with the tab containing the table selected, the column headers stay at their standard size and nothing lines up.
To make things more complicated, I also put System.out.println's in as every method called in the process to obtain the size of the table header. And every println returned the same height, the height the table header should be.. So I'm really confused.
Could anyone shed any light on this?
Thanks.

Okay I managed to solve the problem by explicitly revalidating and repainting the table header.
Not sure why it wasnt doing it properly for that table when all the others where fine.
Oh well...

JTable in JPanel in JTabbedPane in JScrollPane in JSplitPane problem

I have a JSplitPane with a divider in the center; of which the top is a JPanel and the bottom is a JScrollPane that contains a JTabbedPane, for which each tab contains a JPanel which contains a JTable.
When I move the divider up, so that it now takes up 75% of the JSplitPane, the JScrollPane and the JTabbedPane expand with the JSplitPane, but the JPanel that contains the JTable remains the same size that it had at the beginning.
What I would like to see is more rows of the JTable as I move the divider to give the JScrollPane more room.
Is there an easy way to keep all of the J components sizes in sync as the JSplitPane gets larger or smaller ? (JDK 1.3.1)

Hi,
The JPanels which you have inside each tab of the JTabbedPanes should have BorderLayout and the JScrollPanes which hold the JTables should be added with the BorderLayout.CENTER constraint. This will make sure that the JScrollPanes that contain the JTables occupy as much space as possible.
Hope this helps,
Ranga.

JTable in JTabbedPane

Hello
I have a little GUI problem. I created a dialog with a JTabbedPane in the center that contains some JPanel with labels, fields etc. (nothing heavy). The Dialog has a size about 100px*200px.
Now I put a JTable (with no sizing information) in a JScrollPane and add it to the JTabbedPane and the Dialog gets a size of about 200px*200px.
Why? I tried a lot, but nothing helped?
Thankful for every help.

Oh sorry,
I want that the JTable (and the JScrollPane) adopts the size of the Dialog (before I added the table). I don't set any size in my code for the dialog and the panels. I set only size for some JFields in the panels and pack() the dialog.
First everything is wonderfull aligned, but when I add the scrollpane with the table the whole dialog becomes wider.
Is there a chance that the new tab gets the old size?

Ctrl PgUp / CtrlPgDown in JTables vs JTabbedPanes

Hi there, another wee JTable problem.
I want Ctrl PageUp and Ctrl PageDown to move between JTabbedPanes. This normally works, except when the focus is currently in a JTable. I want it to also work if the focus is in a JTable.
I have tried to stop the JTable from handling the keys by setting the inputmap to "none" but this has no effect (you can see my code for this below).

          // Turn off Ctrl PgUp and Ctrl PgDown handling so tab navigation works.
          InputMap inputs = getInputMap(JTable.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);

JTabbedPane modifying a JTable

Can a JTabbedPane change the internal layout of a component ?.
I have a pane with some labels and a JTable inside with a layout. It looks fine when setting it as the content pane of a frame, but when I add it to a JtabbedPane in a new tab the JTable looks wrong.
I am using a TableLayout, i don't know if it has something todo with the problem.
Any idea what i'm doing wrong ?

Any idea what i'm doing wrong ? Absolutely none.

Adding JPopupMenu to JTable cell

Hi,
I am just wondering if I can add a JPopup menu to each cell in a JTable, so that a user can perform some tasks.For example , a user should be able to delete a table cell by choosing the delete menu item in the popup menu
many thanks
Ramesh

Hi,
Add JPopupmenu and add JMenuItems on that according to your requirement. Add MouseListener to your table and on mouseReleased event check whether you have clicked the right mouse. If right mouse is clicked, then show the popup menu that you have already created. I think the following code will help you.
JPopupMenu lJPopupMenu = new JPopupMenu();
JMenuItem lJMenuItem1 = new lJMenuItem();
lJPopupMenu.add(lJMenuItem1);
lJTable.addMouseListener(this);
MouseReleased(java.awt.event.MouseEvent mouseEvent) {
if(mouseEvent.isPopupTrigger()){
lJPopupMenu.show(lJTable, mouseEvent.getX(), mouseEvent.getY());
ActionPerformed of the JMenuItem, you write the code based on the requirement.

JTable and JTabbedPane questions

I have an application which has some JTabbedPanes setup, one of which has a table on it.
What i'm after is a way of having a user select a row from the table and in doing so this will send them to another tabbedpane.
So what i need is a way of assigning each row an ID number, then being able to extract this ID, and being able to switch to a new tab without having to click on the tab itself.
I hope someone can point me in the right direction.
One more question as well.
I'm designing a networked bulletinboard application (using javaspaces) and i'm having an implementation issue.
At the moment I can list all the topics in a table which just contains |the author, topic title and date created|.
I'm having trouble thinking of a good way of displaying the actuall topic itself (and multiple follow-up posts).
I was thinking of doing this in another table, but i couldnt find a way of customizing the layout enough to display formatted text. So i thought I would just do a loop of JTextAreas for each topic.
Something along the lines of:
while (i < number_of_posts)
Create_JTextArea(post[i]);
Do you think this would be a suitable way of implementing this? Or is there a better way that i'm missing?

So what i need is a way of assigning each row an ID numberStore the ID number in the TableModel. You then just remove the TableColumn from the TableColumnModel and the ID will not be displayed in the table. You then simply use model.getValueAt(...) to reference the ID.
