Your ::handle() method is attempting to process window events as if
they were keyboard events, which will not work, so you need to do
something a bit more elaborate here:
Here's the example I worked up - although it seems to be broadly
equivalent to Albrecht's version, so probably you already have the
answers... Tested on OSX with your first example code, works as
expected.
/* handle the event */
int Canvas::handle(int event)
{
int result = Fl_Box::handle(event);
switch(event)
{
case FL_KEYBOARD:
switch(Fl::event_key())
{
case FL_Right:
XC = XC + 1;
redraw();
return 1;
case FL_Left:
XC = XC - 1;
redraw();
return 1;
case FL_Up:
YC = YC - 1;
redraw();
return 1;
case FL_Down:
YC = YC + 1;
redraw();
return 1;
default:
return result;
}
case FL_FOCUS:
case FL_PUSH:
return 1;
default:
return result;
}
} // Canvas::handle
