Hi,
In VE 1.0M2, setting the owner Frame of a JDialog prevents VE from
displaying the dialog.
If I create a JDialog in my GUI, VE creates a method like this...
private JDialog getJDialog() {
if(jDialog == null) {
jDialog = new JDialog();
jDialog.setContentPane(getJContentPane());
}
return jDialog;
}
The only way I know of setting the owner Frame of this JDialog is to
pass it in the ctor, like this...
private JDialog getJDialog() {
if(jDialog == null) {
jDialog = new JDialog(this);
jDialog.setContentPane(getJContentPane());
}
return jDialog;
}
....where 'this' is the top level JFrame subclass also created in VE.
This worked in VE in eclipse2, but in eclipse3 the JDialog will not
display due to the following error...
java.lang.IllegalArgumentException (IWAV0001E Currently "this" is not
supported)
Is there a work-around?
Chris.

Opps. I thought there was a way to set the owner. So until I fix the
defect with "this" in CTORs there is no workaround. Sorry. :-(

I have an open defect to allow more support of the "this". The problem
we have is that we try to do exactly what you state in the code, but
there is no "this" during design time. That is because we are in the
process of creating/modifying "this" and we can't run a real "this"
because it is constantly changing. The old VE code had some special
checks in it for JDialog and "this" and understood it, but we revamped
completely how this works to give us more flexibilty, but we lost the
"this" capability.
One workaround for the moment may be to add a jDialog.setParent(this);
right after the constructor. You'll probably get a warning on the
setParent() from the VE but it won't stop the JDialog from being created
and seeing the dialog in the VE.

Perhaps VE could try calling a no-args ctor if the ctor in the code fails.

This won't work as JDialog doesn't have a setParent() method, or any
other way of setting the parent other than in the ctor.
The only work-around is to remove the ctor args while designing and
remember to put them back for running.
Frankly, I'm amazed that VE works at all without any source annotations.
It's cool stuff!
Chris.
