gtkmm provides four basic types of buttons:
Note that, due to GTK+'s theming system, the appearance of these widgets will vary. In the case of checkboxes and radio buttons, they may vary considerably. There are two ways to create a Button. You can specify a label string in the Gtk::Button constructor, or set it later with set_label(). To define an accelerator key for keyboard navigation, place an underscore before one of the label's characters and specify true for the optional mnemonic parameter. For instance: Gtk::Button* pButton = new Gtk::Button("_Something", true); Wherever possible you should use Stock items, to ensure consistency with other applications, and to improve the appearance of your applications by using icons. For instance, Gtk::Button* pButton = new Gtk::Button(Gtk::Stock::OK);This will use standard text, in all languages, with standard keyboard accelerators, with a standard icon. Gtk::Button is also a container so you could put any other widget, such as a Gtk::Image into it. This example creates a button with a picture and a label. File: buttons.h #ifndef GTKMM_EXAMPLE_BUTTONS_H #define GTKMM_EXAMPLE_BUTTONS_H #include <gtkmm/window.h> #include <gtkmm/button.h> class Buttons : public Gtk::Window { public: Buttons(); virtual ~Buttons(); protected: //Signal handlers: virtual void on_button_clicked(); //Child widgets: Gtk::Button m_button; }; #endif //GTKMM_EXAMPLE_BUTTONS_H File: buttons.cc #include "buttons.h" #include <iostream> Buttons::Buttons() { m_button.add_pixlabel("info.xpm", "cool button"); set_title("Pixmap'd buttons!"); set_border_width(10); m_button.signal_clicked().connect( SigC::slot(*this, &Buttons::on_button_clicked) ); add(m_button); show_all_children(); } Buttons::~Buttons() { } void Buttons::on_button_clicked() { std::cout << "The Button was clicked." << std::endl; } File: main.cc #include <gtkmm/main.h> #include "buttons.h" int main(int argc, char *argv[]) { Gtk::Main kit(argc, argv); Buttons buttons; Gtk::Main::run(buttons); //Shows the window and returns when it is closed. return 0; } Note that the XPMLabelBox class can be used to place XPMs and labels into any widget that can be a container. The Gtk::Button widget has the following signals, but most of the time you will just handle the clicked signal:
