Eclispe 2.1.2 with GEF for 2.1.2
I am using draw2d to do some layered rectangle drawing in a canvas in one
page of a multi-page editor. The outer control in the page is a
ScrolledComposite, and inside that down a level or two is the Canvas with
the LightweightSystem inside it.
On linux/gtk, the draw2d figures only render if the whole enclosing canvas
is visible. i.e. if the page size is limited so the outer scrolledcomposite
is clipping, the canvas, then the canvas is blank. If I resize the page so
the canvas is fully visible, then all the draw2d content is rendered. Make
it smaller ... and poof it all vanishes again.
On win32, all behaves as I would expect - it clips and renders nicely.
Is this an SWT/GTK problem? or am I just "lucky" on win32 and need to recode
some other way to make it portable
TIA

Just tested on solaris/motif : also works fine.
So, an swt/gtk bug maybe? Any suggestions of a workaround I can try?
TIA
