Gimp Undo System

Hello,

I'm changing the content of an image using pixel_region_set_row(). After that, I want to introduce my changes in the Undo Stack.

So, I start an undogroup with gimp_image_undo_group_start (image, GIMP_UNDO_GROUP_PAINT, "test").
After, I call the function gimp_drawable_push_undo(drawable, NULL, x1, y1, x2,y2,tilemanager , TRUE).
I finish the undo group with gimp_image_undo_group_end(image).

When I start to draw, "test" is added to the stack (I see it in the undo window).
But when I do ctrl+z, nothing happens.

With gdb and backtrace, I see that when I draw, after the group is created, gimp_image_undo_push is called is called before gimp_drawable_push_undo. I add it but there is no changes.

Does anybody have an idea of what is wrong?

Kind Regards,

Radhwan
