Hi All,
I need to develop a SEMI-TRIANGLE shaped of the custom button control. I
have successfully did it in full framework. However, when i'm about to do the
porting to CF, there are heaps of problems.
1. I can't find any GraphicsPath in CF
2. There is no region class which accept the graphics path datatype.
The accuracy of region is important because i need to locate the button in a
very close position with other image (otherwise, the two rectangle will
collide). I saw some example which draw the ellipse button in CF. However,
when i tried it out, it seems that it is not really ellipse because if we
click it somewhere outside the ellipse but inside the rectangle size (form),
it works.
Are there anyone have the workaround for these problems? Thank you in
advance for the helps. I would provide my code (full framework) just in case
my explanation
is confusing.
