Setting Window Class Hints

The "class hint" is a property of GtkWindow window managers can read to decide how to treat the window. Most window managers allow you to set icons and other properties based on the class hint. Two elements make up the hint. The wmclass_name field should be unique for each kind of toplevel window in an application (such as the main window or a tools dialog). The wmclass_class field is conventionally set to the name of the application, capitalized. For example: xterm windows set these properties to xterm (name) and XTerm (class). The GIMP toolbox sets its name to toolbox and its class to Gimp. The gtk_window_set_wmclass() function sets these hints for GtkWindow.

#include <gtk/gtkwindow.h>

void gtk_window_set_wmclass(GtkWindow* window, const gchar* wmclass_name, const gchar* wmclass_class);
