Hi,
I am using the class CombinedTemplateCreationEntry for adding items to =
the Palette.
I pass this class an ImageDescriptor to display the icon in the palette, =
which is resulting in a memory leak.
Is there a way to get a handle to the image created to dispose it ?
Here is a code snippet:
Image img =3D new Image(....);
ImageDescriptor desc =3D ImageDescriptor.createFromImage(img);
CombinedTemplateCreationEntry entry =3D new =
CombinedTemplateCreationEntry( p1,p2, obj, fact, desc,desc);
Even if I dispose "img" when the editor is closed, I still see a memory =
leak.=20
Adding the descriptor to an ImageRegistry and calling dispose on the =
registry doesnt help either.
Thanks,
Vikram

Hi,
The image is created dynamically from another image, not from a file.
I have tried to put this in a descriptor as well, but that doesnt help.
I am using the Sleak tool which shows the leak.
Thanks,
Vikram

This is a bug in GEF. ResourceManager support was added to =
EditPartViewer in 3.3. The PaletteViewer should not have its own =
ImageCache any more, it should use the ResourceManager instead. A =
bugzilla is probably open on this already. This permanent leak of =
Images was borrowed from ActionContributionItem way back when, but when =
it cleaned up its act, GEF didn't follow suit.
Are you interested in providing a patch to =
PaletteEditPart#setImageDescriptor(...)?
