Re: [wxperl-users] DCPaint Widget Question

[Mark D. <mar...@zn...>]

Hi,

I was trying to explain a lot of steps and concepts when really some
example code would have been better.

As I want to complete something myself where I have to move drawn
objects about a canvas, I made sure what I was proposing actually works
with an example which I've posted at:

http://www.wxperl.co.uk/example3.pl.txt

I'm not sure if it would work with the wxGDI interface, but if I had a
lot of objects to draw I could speed up the user experience by doing the
actual drawing to a separate memoryDC only when the drawing objects
actually changed. Then for screen updates, I'd use the built-in fast
bitmap BitBit function ($dc->Blit() ) to just copy the region of the
bitmap I needed to update to the screen.

But with fewer objects to draw, the approach in the example should work
just fine.

Regards

Mark
