[Gambas-user] Reading pen pressure from wacom tablets

[Ricardo Díaz Martín]

Ok, this is the information I got:

- When I said crash in the IDE too, it means after the crash in the
project, if you still moving the pen in the tablet, the IDE got the crash
with no information (IDE disappear)
- With gtk+ components the tablet is not detected. Tablet is detected as
normal mouse. No crash in the project. No crash in the IDE.
- The event Move, Down, Up are right fired. Work as expected with the pen
and with the mouse.
- If you set Tracking property to true in the drawing area control you you
got the MouseDown event and MouseUp event some times is fired and some
times no.
- I got the same crash by compiling gambas with no qt4 optimizations

gdb with gambas3 qt4 no optimizations compiled was:
Starting program: /usr/local/bin/gbx3
