I've been confused by the fullscreen() function. What is the rationale for a
different process for X11 than for Windows and Mac? Here is the function:
void Fl_Window::fullscreen() {
#ifndef WIN32
//this would clobber the fake wm, since it relies on the border flags to
//determine its thickness
border(0);
#endif
#if defined(__APPLE__) || defined(WIN32)
int sx, sy, sw, sh;
Fl::screen_xywh(sx, sy, sw, sh, x()+w()/2, y()+h()/2);
// if we are on the main screen, we will leave the system menu bar
unobstructed
if (Fl::x()>=sx && Fl::y()>=sy && Fl::x()+Fl::w()<=sx+sw &&
Fl::y()+Fl::h()<=sy+sh) {
sx = Fl::x(); sy = Fl::y();
sw = Fl::w(); sh = Fl::h();
}
if (x()==sx) x(sx+1); // make sure that we actually execute the resize
resize(sx, sy, sw, sh);
#else
if (!x()) x(1); // force it to call XResizeWindow()
resize(0,0,Fl::w(),Fl::h());
#endif
}
I find that the fullscreen behaves incorrectly relative to the GNOME taskbar
and multiple displays, but if I just make all the different platforms use the
same process:
void Fl_Window::fullscreen() {
#ifndef WIN32
//this would clobber the fake wm, since it relies on the border flags to
//determine its thickness
border(0);
#endif
int sx, sy, sw, sh;
Fl::screen_xywh(sx, sy, sw, sh, x()+w()/2, y()+h()/2);
// if we are on the main screen, we will leave the system menu bar
unobstructed
if (Fl::x()>=sx && Fl::y()>=sy && Fl::x()+Fl::w()<=sx+sw &&
Fl::y()+Fl::h()<=sy+sh) {
sx = Fl::x(); sy = Fl::y();
sw = Fl::w(); sh = Fl::h();
}
if (x()==sx) x(sx+1); // make sure that we actually execute the resize
resize(sx, sy, sw, sh);
}
The fullscreen() function behaves as I would expect.
