Something like this may work (untested code follows):
class MainWindow : public Fl_Double_Window {
public:
MainWindow(int w, int h, char const* label = 0)
: Fl_Double_Window(w, h, label)
, visible_(false)
{;}
void show()
{
Fl_Double_Window::show();
visible_ = true;
while(visible_) {
Fl::wait();
}
}
void hide()
{
Fl_Double_Window::hide();
visible_ = false;
}
private:
bool visible_;
};
void main_thread()
{
MainWindow window(300, 300); // Create main window (hidden)
window.end();
// Create pipe thread
bool done = false;
do {
// Pipe thread Fl::awake()'s the main thread
if(whatever) window.show(); // perhaps show/hide the main window
// display what we're told to via the pipe
if(something) done = true;
} while(!done); // repeat until told to quit
}
