The Mouse Pointer

The mouse pointer is represented on the screen by a small bitmap called the cursor. The cursor is normally an arrow shape, but it can be changed on a window-by-window basis. As the pointer moves, it generates motion events and moves the cursor on the screen to give the user feedback.

Pointer Location

You can query the pointer's location with gdk_window_get_pointer() (Figure 7). This function requests the X and Y coordinates of the pointer relative to the window passed as its first argument. It also requests the currently active modifiers (including modifier keys and buttons; this field is identical to the state field in several events, such as button events). If NULL is passed for the x, y, or state arguments, that argument will be ignored.

#include <gdk/gdk.h>

GdkWindow* gdk_window_get_pointer(GdkWindow* window, gint* x, gint* y, GdkModifierMask* state);
