Hi,
I tried to change the text of the buttons in
org.eclipse.jface.dialogs.InputDialog. I made own InputDialog class that
had jface InputDialog as superclass and did a methods that should of
return the buttons. I tried both InputDialog class getOkButton() and
Dialog class getButton(id), but bot returns null. Here's what I tried:
------------------------------------------------------------ ---------
import org.eclipse.jface.dialogs.IInputValidator;
import org.eclipse.jface.dialogs.InputDialog;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Shell;
public class myInputDialog extends InputDialog {
public myInputDialog(Shell arg0, String arg1,
String arg2, String arg3, IInputValidator arg4) {
super(arg0, arg1, arg2, arg3, arg4);
}
public Button getMyOkButton(){
return getOkButton();
}
public Button getMyButton(int id){
return super.getButton(id);
}
}
------------------------------------------------------------ ---------
getMyButton method is called with: getMyButton(IDialogConstants.OK_ID);
but they both return null. Should it work this way?
I also tried to override the createButtonsForButtonBar method in
InputDialog and created the buttons my self like this:
------------------------------------------------------------ ---------
protected void createButtonsForButtonBar(Composite parent) {
okButton = createButton(parent, IDialogConstants.OK_ID,
IDialogConstants.OK_LABEL, true);
cancelButton = createButton(parent, IDialogConstants.CANCEL_ID,
IDialogConstants.CANCEL_LABEL, false);
}
------------------------------------------------------------ ---------
But by overriding the createButtonsForButtonBar method broke the
InputValidator of the InputDialog. I guess the text widget did not get
created when doing this, atleast the stacktraces pointed that way.
Anyways, any help on this would be much appreciated!

You call these methods in wrong time.
Until open() (or create()) buttons are not created.
