Hi Ian,
I built the resize example, and it works fine. But my example still doesn't!
I use resize() just like in the example, with a very simple window.
The only difference I see is that the window I'm resizing is not the
main window, but a popup window made on the fly. So in pseudo code
main {
MyOwnClass* main_obj = new MyOwnClass();
Window* main_win = new Window();
main_obj->add(main_win);
main_obj->main_win->show();
return run();
}
void cb_fromMenuItemInMainWin() {
Window* pop = new Window();
Button* resize_but = new Button();
resize_but->callback(cb_resize);
pop->add(resize_but);
pop->show();
}
void cb_resize() {
Window* pop = o->window();
pop->resize(pop->w(), pop->h() + 10);
}
Also, I would like the popup window to resize without the contents
resizing with it (I want to add more contents). Any hints on that?
Thanks!
VA
