I have an outline linked to a page in an editor. A click on the outline
causes the pages body to contain a single composite with a section header
and some questions for the user. When a different entry in the outline is
selected the composite is disposed and a new one created. I have one
composite (QuestionComposite) which creates a section with a twistie and
contains a browser element.

When this composite is disposed it triggers a paint event which eventually
throws a widget disposed error. The code runs fine under XP but errors
under Windows 7. Both machines are fully workspace synched to the same cvs
store.

The .ConfigPage.changeSelection disposes of the old composite containing
the section twistie with broswer data under the twistie. This happens even
when the twistie is not opened.

Any idea how I can workaround this and do I need to raise a bug for it.

Hi,

Yes, please log a report with SWT (
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Platform &component=SWT ),
and provide some means of reproducing the problem. Also be sure to mention
that it only happens as of Windows 7. The only workaround I can suggest
trying (may not work) is to first dispose each of the Composite's children
before disposing the Composite. Since WM_PAINT is coming for a Control that
is supposed to be disposed, perhaps it's actually coming from a contained
handle that is mapped to the SWT Control that is marked as disposed.

HTH,
Grant



<Phill_Perryman@Mitel.COM> wrote in message
news:hhsnth$qlt$1@build.eclipse.org...

I have an outline linked to a page in an editor. A click on the outline
causes the pages body to contain a single composite with a section header
and some questions for the user. When a different entry in the outline is
selected the composite is disposed and a new one created. I have one
composite (QuestionComposite) which creates a section with a twistie and
contains a browser element.

When this composite is disposed it triggers a paint event which eventually
throws a widget disposed error. The code runs fine under XP but errors under
Windows 7. Both machines are fully workspace synched to the same cvs store.

The .ConfigPage.changeSelection disposes of the old composite containing the
section twistie with broswer data under the twistie. This happens even when
the twistie is not opened.

Any idea how I can workaround this and do I need to raise a bug for it.
