jdialog

I Have the following code: import java.awt.AWTEvent; import java.awt.ActiveEvent; import java.awt.Component; import java.awt.EventQueue; import java.awt.MenuComponent; import java.awt.event.MouseEvent; import javax.swing.JInternalFrame; import javax.swing.SwingUtilities; public class modalInternalFrame extends JInternalFrame { // indica si aquest es modal o no. boolean modal = false; @Override public void show() { super.show(); if (this.modal) { startModal(); } } @Override public void setVisible(boolean value) { super.setVisible(value); if (modal) { if (value) { startModal(); } else {

We need a CellEditor for a JTable for editing a large multiline-text. We tried using a popup visually extending the TableCell , which was overlapping the cells to the right and bottom. This led to various problems if the cell was in the right bottom corner, near the screen-boundaries, etc. Then we decided to use a modal JDialog for editing the cell-value. So the users could move the dialog around, and we could persist its size and position. Now the problems started ;-) We are not able to "forward" the first typed character to the Dialog. There are many examples on stack overflow, where this

After reading through all the Dialog tutorials for a while, there seems to be no apparent way to do this. The closest thing seems to be JOptionPane.showOptionDialog , but I am limited by the optionType parameter here. EDIT: I figured out the problem, but have a new one. It seems that the options parameter being specified in showOptionDialog needs to be fairly simple objects (strings or just 'objects', not JButton or the like). I was trying to put an array of custom-factory-created JButtons here, because they have a special rollover icon that I want to be using. What happens, though, is that

I have created a JDialog which contains a JLabel. Because the length of text, which changes based on users' input, can contain a large number of characters, there is the need to dynamically change the length of the JDialog based on the size of length of the JDialog. I have tried the pack() method but it's not the case for it. Can anyone give me some tips? Thanks in advance! mKorbel getPreferredSize for JLabel - basically you have to get textLength from JLabel in pixels, there are 3 correct ways, but I love: SwingUtilities.computeStringWidth(FontMetrics fm, String str) Now you are able to

When researching the problem, it seems most people are wanting to do the opposite (i.e remove the minimize/close button). I've had no success using the reoccurrent setUndecorated and setDefaultCloseOperation Here is my code: private class TestDialog extends JDialog { public static final String title_ = "Test Dialog"; public TestDialog(JFrame parent) { super(parent,title_,true); setMinimumSize(new Dimension(500,500)); setLocationRelativeTo(null); setUndecorated(false); setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE); } } When I display the dialog I get the following: Other info: OS:

I used JOptionPane.showOptionDialog(null, new MyPanel(), "Import", JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE, null, new Object[]{}, null); because I don't want the default buttons provided by the OptionDialog and I created my buttons inside the MyPanel extends JPanel So my problem is now how can I close that OptionDialog from inside the MyPanel fired by an ActionEvent ? I don't care the return value, as long as that dialog disappears. And I realize this might not be the best design but I've been working on this for a lot of times so I'd prefer a fix that involves as little change
