I guess you mean your morph. #ClipsSubmorphs is implemented by
morphs, not by the canvas.<br>

You should not redefine this method. Your morph should only define
#clipsSubmorphs.<br>

Let's try a simple example in a Workspace.<br>
<br>
"Pull repo"<br>
ChangeSet installNewUpdates.<br>
Feature require: 'VectorGraphics'.<br>
m1 := M3Exp01Morph new.<br>
m2 := M3Exp02Morph new.<br>
m1 addMorph: m2.<br>
m1 openInWorld<br>
<br>
This opens a m1 happy face, covered by an unclipped round rectangle.
Zoom it with the halo handle. Then, using the middle button, open
the halo of the inner M3Exp02Morph. Make it smaller, so the round
rectangle partially covers the smiley. Now add this method to
M3Exp01Morph:<br>
<br>
clipsSubmorphs<br>
^true<br>
<br>
and Restore Display. You can see the red interior and green border
of the inner morph, clipped to the happy M3Exp01Morph.<br>
<br>
Vector canvas can clip morphs to the arbitrary shape of the outer
morph. But it has a limitation: In a containment branch, there can
be only one morph that clips submorphs. Do you need more than one
clipping morph? Can you provide an example showing the problem you
see, so I can reproduce it?<br>
<br>
Thanks,<br>
