158 * @GDK_CONTROL_MASK: the Control key.
159 * @GDK_MOD1_MASK: the fourth modifier key (it depends on the modifier
160 * mapping of the X server which key is interpreted as this modifier, but
161 * normally it is the Alt key).
162 * @GDK_MOD2_MASK: the fifth modifier key (it depends on the modifier

164 * @GDK_MOD3_MASK: the sixth modifier key (it depends on the modifier

176 * @GDK_SUPER_MASK: the Super modifier. Since 2.10
177 * @GDK_HYPER_MASK: the Hyper modifier. Since 2.10
178 * @GDK_META_MASK: the Meta modifier. Since 2.10
179 * @GDK_RELEASE_MASK: not used in GDK itself. GTK+ uses it to differentiate
180 * between (keyval, modifiers) pairs from key press and release events.
181 * @GDK_MODIFIER_MASK: a mask covering all modifier types.
183 * A set of bit-flags to indicate the state of modifier keys and mouse buttons
184 * in various event types. Typical modifier keys are Shift, Control, Meta,
185 * Super, Hyper, Alt, Compose, Apple, CapsLock or ShiftLock.
187 * Like the X Window System, GDK supports 8 modifier keys and 5 mouse buttons.
189 * Since 2.10, GDK recognizes which of the Meta, Super or Hyper keys are mapped
190 * to Mod2 - Mod5, and indicates this by setting %GDK_SUPER_MASK,
191 * %GDK_HYPER_MASK or %GDK_META_MASK in the state field of key events.
193 * Note that GDK may add internal values to events which include
194 * reserved values such as %GDK_MODIFIER_RESERVED_13_MASK. Your code
195 * should preserve and ignore them. You can use %GDK_MODIFIER_MASK to
196 * remove all reserved values.

324 * spends a lot of time processing the event (updating the display, for example),
325 * it can lag behind the position of the mouse. When using
326 * %GDK_POINTER_MOTION_HINT_MASK, fewer %GDK_MOTION_NOTIFY events will be sent,
327 * some of which are marked as a hint (the is_hint member is %TRUE).

329 * needs to asks for more, by calling gdk_event_request_motions().
