Hello,
I want to draw a small button completely filled with a custom image.
The "bounding path" of the image is a circle and I want my button to
be circular and just a tad bigger than the custom image (radius of
button = radius of image + 2 pixels).
I set the button shape and image with the following sequence:
...
[button setButtonType:NSMomentaryPushInButton];
[button setBezelStyle:NSRecessedBezelStyle];
[button setImage:bImage];
...
and the image does show up.
However, it seems that the button is drawn of a middle component (a
rectangle, I think) and two semicircles on the left and right side.
If the button size is too small, then these two semi-circles overlay
the image in the middle and obscure part of the image. It seems that
the drawing algorithm for the button is: draw rectangular portion in
the middle, draw image on top, draw two semicircles on left and right
to complete button.
Is that the expected behavior or a bug? What would be the way to
go? This behavior seems to be persistent across all button styles I
experimented with. The only thing left to try I can think of is to
make the button transparent, then draw the actual button shape and
the image (not sure if possible and seems too difficult).
Any suggestions? Thanks,
-- ivan
