So am I. Example code is any basic QD graphics call like:
SetRect r,left, top, right ,bottom
SetForeColor 205 ' red
FrameRect r
I decided to migrate my code from QD because the writing is on the wall...
So I ran into another problem (this concerns the classic "marching
ants" selection outlines used on the Mac since the beginning). Doing
this in QD was easy, with a pen pattern and a timer that shifted the
pattern and re-drew the outline every 1/4 second or so, simulating a
march.
Forget the march, all I want now is a dashed border for my rects: is
there a way to dash a figure border of RB's built-in Object2D's, like
a RectShape? Surely OpenGL (I gather this is what Object2D's are
based on?) can do this and much more, but I don't see how off-hand.
Any pointers?
Thanks!
