Janak,
Thank you for your answer, it was very helpful and I am now able to
position the dialog where I want it.
I have a different problem now though with the dialog text field.
About 1/8 of the time when the dialog pops-up the text fields does not
have focus (the cursor is not in the text field) and most frustratingly
I can not enter any text into the text field. I must close the dialog
and re-open it, sometimes 3 or 4 times before I can enter text in the
field.
Following is the dialog code:
private void showModalDialog(ULCTable table, String col, Point location)
{
ULCFrame parent = new ULCFrame();
final ULCDialog dialog = new ULCDialog(parent, "Search " + col);
ULCBoxPane dialogPane = new ULCBoxPane(1, 2);
final ULCTextField text = new ULCTextField(25);
text.setText(col);
text.select(0,col.length());
text.setBackground(Color.lightGray);
text.requestFocus();
dialogPane.add(ULCBoxPane.BOX_LEFT_CENTER, text);
ULCButton closeButton = new ULCButton("Search");
closeButton.addActionListener(new IActionListener() {
public void actionPerformed(ActionEvent actionEvent) {
dialog.setVisible(false);
searchTableData(searchColumn, text.getValue());
}
});
dialogPane.add(ULCBoxPane.BOX_RIGHT_BOTTOM, closeButton);
dialog.add(dialogPane);
dialog.setDefaultButton(closeButton);
dialog.setSize(250, 150);
dialog.setResizable(false);
dialog.setLocation(location);
dialog.setVisible(true);
text.setVisible(true);
}
