..and just to clarify, by that I mean when creating the second window
"new Fl_Window(w,h)" makes a separate window, whereas
"new Fl_Window(x,y,w,h)" makes it a subwindow (widget inside outer window)
So in other words this should work:
#include <FL/Fl_Double_Window.H>
#include <FL/Fl.H>
#include <iostream>
class MyWindow : public Fl_Double_Window {
public:
MyWindow(int w, int h, char const* label = 0)
: Fl_Double_Window(w, h, label)
{;}
MyWindow(int x, int y, int w, int h, char const* label = 0) // ADDED
: Fl_Double_Window(x, y, w, h, label) // ADDED
{;} // ADDED
~MyWindow() { std::cout << "Deleted " << label() << std::endl; }
};
int main()
{
MyWindow* win1 = new MyWindow(300, 300, "Window 1");
MyWindow* win2 = new MyWindow(0,0,300, 300, "Window 2"); // CHANGED
win2->end();
// win2->parent(0);
win1->end();
delete win1;
return(Fl::run());
}
