1.2.3GA: "Edit Fame" in ScrolledComposite

[cebarne2]

Nothing happens when I click "Edit Frame" in my scrolled composite. The following exception occurs in the log:

Code: Select all

Here is a bit of code where I use my custom frames in the ScrolledComposites:

Code: Select all

{
            final TabItem tabBuildPaths = new TabItem(tabFolder, SWT.NONE);
            tabBuildPaths.setText("Build Paths");
            {
               final ScrolledComposite scrolledComposite = new ScrolledComposite(tabFolder, SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL);
               tabBuildPaths.setControl(scrolledComposite);
               {
                  pgBuildPaths = new buildPaths(scrolledComposite, SWT.NONE);
                  pgBuildPaths.setSize(735, 303);
                  scrolledComposite.setContent(pgBuildPaths);
               }
            }
         }
         {
            final TabItem tabPathsSymbols = new TabItem(tabFolder, SWT.NONE);
            tabPathsSymbols.setText("Paths && Symbols");
            {
               final ScrolledComposite scrolledComposite = new ScrolledComposite(tabFolder, SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL);
               tabPathsSymbols.setControl(scrolledComposite);
               {
                  final PathsAndSymbols pathsAndSymbols = new PathsAndSymbols(scrolledComposite, SWT.NONE);
                  pathsAndSymbols.setSize(735, 303);
                  scrolledComposite.setContent(pathsAndSymbols);
               }
            }
         }

Something wrong on my end, or yours?

Thanks

Hm...
I can not reproduce this. Can you provide separate test case and/or may be describe more specific your environment?

[cebarne2]

Here's the low-down on my environment:

-Windows XP
-Eclipse 2.1.2
-Java 1.4.1_05
-SWT Designer 1.2.3 GA

And, here is a list of plug-ins:

-cbg.editor
-net.sf.colorer
-com.rational.clearcase_2.2.36
-com.rational.cqresultset_2.2.7
-net.sf.versiontreee

I'll try to email the project directly to you.

Thanks,
Chad

Yes, we can reproduce it 2.1.2, we for 3.0 we don't have such
problem. We will try to fix it for 2.1.2, in mean time you could use
3.0, if this is possible in your project.

Our current installed-base is 2.1.x, so am very interested in a fix.

Thank you for your support on this issue.

Our current installed-base is 2.1.x, so am very interested in a fix.

With the sample code you sent, it seems to be working for me under both 2.1.2 and 3.0 (this may be due to another bug fix that we made recently). I will post a new build for you to try very soon. Watch this forum for the announcment.
