Hi Tomek.
To receive keys, you need focus.
For focus, you need a visible layer.
If you do CreateSurface, you still do not see something.
If you create the surface of the primary layer, you are almost there.
Only when you do "flip()" the surface is actually shown on the layer.
This is to make sure that no garbage is shown when you do CreateSurface().

Compilation go ok.
In all cases no error while program runs.
If I write (1a) - I do not have to write (2) and everything is ok.
But if I write (1b) and I do not write (2) then program just hang up
on (3)-WaitForEvent(), if I press button program does not go further.
I need to write (2):
- I need to create _PRIMARY surface
- I need to flip this surface
( If I do not flip surface, or if it is not _PRIMARY surface then
program hang up. So I need to do both.)
And then everything goes ok.
I am toothless.
Any suggestions? Please.
Regards,
Tomek.
