I simply want to know which size a widget has. I need this info to set a
ScrolledWindow to a maximum size if the size of the widget is bigger
than the screen.
But all functions I know give a constant value of 1.
#include <iostream>
#include <gtkmm.h>
#include <gtkmm/window.h>
class ExampleWindow: public Gtk::Window
{
Gtk::Button button;
public:
ExampleWindow(): button("Hallo")
{
add(button);
GetSize();
}
void GetSize()
{
std::cout << button.get_width() << " " << button.get_height()
<< std::endl;
std::cout << button.get_allocated_width() << " " <<
button.get_allocated_height() << std::endl;
}
};
int main(int argc, char* argv[])
{
Gtk::Main kit(argc, argv);
ExampleWindow window;
window.GetSize();
window.show_all_children();
window.GetSize();
Gtk::Main::run(window);
return 0;
}
