Hi,
I'm trying to draw into an existing X11 window using fltk2.
I tried to modify the hello.cxx accordingly (see below).
It already draws a small border in the right window when I
pass it the (decimal) id of an existing window, but
not the whole content is rendered properly.
What am I missing?
Thanks,
Johannes
// hello.cxx (example1)
#include <stdlib.h>
#include <fltk/Window.h>
#include <fltk/Widget.h>
#include <fltk/run.h>
#include <fltk/x11.h>
using namespace fltk;
class ExtWindow : public Window {
private:
long id;
public:
ExtWindow(long id, int _w, int _h) : Window(_w, _h) {
this->id = id;
};
void create() { CreatedWindow::set_xid(this, id); };
};
int main(int argc, char **argv) {
Window *window = new ExtWindow(atol(argv[1]), 300, 180);
window->begin();
Widget *box = new Widget(20, 40, 260, 100, "Hello, World!");
box->box(UP_BOX);
box->labelfont(HELVETICA_BOLD_ITALIC);
box->labelsize(36);
box->labeltype(SHADOW_LABEL);
window->end();
window->show();
return run();
}
