After click on "reparse" everything seems to be ok. But if i place another TextField, Combobox, ... on the panel i get a npe.

Information about my system:
Product: Swing Designer Professional
Version: 7.5.0.r35x201006081432
Actual: Eclipse 3.5.0.v20090525
IDE Actual Version: 3.5.2.v201002111343
OS Name: Windows XP
OS Architecture: x86

cheers, michael

This problem should be fixed in latest build.
It was caused by optimizations which we did in Swing Designer, especially visible for Mac users.

Thanks, for the "normal" components it works now.
But for simple factory-methods i get also an NPE.

The factory-method is very simple.

Code: Select all

   public static JPanel createDefaultPanel() {
      JPanel pnl = new JPanel();
      pnl.setBorder(new EmptyBorder(2, 2, 2, 2));
      return pnl;
   }


If i click on "reparse" everything seems to be ok until i add the next factory-method.

cheers, michael

[Konstantin.Scheglov]

This is actually different problem, related with inheriting layout manager.
You can configure Swing Designer to use on new container same layout manager as its parent uses.
Unfortunately, there was bug in inheriting absolute/null layout.
This is fixed in latest build.

[mkornatzki]

thanks, this works now.

And here comes the next problem (works some versions before).

I have a JFrame with gridbaglayout and a JPanel also with gridbaglayout and some components.
Now i click on "choose component" and select my panel-class.

And i get...

Code: Select all

The same procedure as before...i click repase and it seems to be ok.

cheers, michael

[Konstantin.Scheglov]

Aha...
Problem here is that we create model for exposed component in AWT thread, and this was not expected by other part of SwingDesigner, which wanted to be run in SWT thread.
This should be fixed now in latest build.

[mkornatzki]

great, thank you.

Now it works )

cheers, michael

[Eric Clayberg]

Glad that works for you.
