As Ian said, fltk2 is the same. Just call
windowMain->init_sizes();
at the end of cbXxxBarToggle(..).

There is a focus lost when switching back from fullscreen here.
I think you dont need to hide and show widgets/windows when changing
internal layout. eg.:
if(fullScrState) {
//~ windowMain->hide();
windowMain->fullscreen_off(windowX, windowY, windowW, windowH);
//~ windowMain->show();
everything works fine without that. Same for the other callbacks. If you
think something has to get redrawn, use redraw().
Some other things:
1. You may want to declare
static bool statusBarState = true;
inside your callback, since there is no need to modify them from outside
(This wont pollute the global namespace)
2. Doing
if (statusBarState) {
windowMain->statusBar->hide();
//windowMain->tabsGroup->hide();
windowMain->tabsGroup->h(windowMain->tabsGroup->h() + ...);
//windowMain->tabsGroup->show();
//statusBarState = false;
} else if(!statusBarState) {
is unneccesary code. The second if statement is always true (and might
get removed from optimizer) Just drop that.
3. Toggling boolean state has to be done for both branches:
statusBarState = !statusBarState;
will keep all sane.

You'll always come into trouble. But the source is with you.
