140 /* Types of modifiers.
144 * @GDK_SHIFT_MASK: the Shift key.
145 * @GDK_LOCK_MASK: a Lock key (depending on the modifier mapping of the
146 * X server this may either be CapsLock or ShiftLock).
147 * @GDK_CONTROL_MASK: the Control key.
148 * @GDK_MOD1_MASK: the fourth modifier key (it depends on the modifier
149 * mapping of the X server which key is interpreted as this modifier, but
150 * normally it is the Alt key).
151 * @GDK_MOD2_MASK: the fifth modifier key (it depends on the modifier
152 * mapping of the X server which key is interpreted as this modifier).
153 * @GDK_MOD3_MASK: the sixth modifier key (it depends on the modifier
154 * mapping of the X server which key is interpreted as this modifier).
155 * @GDK_MOD4_MASK: the seventh modifier key (it depends on the modifier
156 * mapping of the X server which key is interpreted as this modifier).
157 * @GDK_MOD5_MASK: the eighth modifier key (it depends on the modifier
158 * mapping of the X server which key is interpreted as this modifier).
159 * @GDK_BUTTON1_MASK: the first mouse button.
160 * @GDK_BUTTON2_MASK: the second mouse button.
161 * @GDK_BUTTON3_MASK: the third mouse button.
162 * @GDK_BUTTON4_MASK: the fourth mouse button.
163 * @GDK_BUTTON5_MASK: the fifth mouse button.
164 * @GDK_SUPER_MASK: the Super modifier. Since 2.10
165 * @GDK_HYPER_MASK: the Hyper modifier. Since 2.10
166 * @GDK_META_MASK: the Meta modifier. Since 2.10
167 * @GDK_RELEASE_MASK: not used in GDK itself. GTK+ uses it to differentiate
168 * between (keyval, modifiers) pairs from key press and release events.
169 * @GDK_MODIFIER_MASK: a mask covering all modifier types.
171 * A set of bit-flags to indicate the state of modifier keys and mouse buttons
172 * in various event types. Typical modifier keys are Shift, Control, Meta,
173 * Super, Hyper, Alt, Compose, Apple, CapsLock or ShiftLock.
175 * Like the X Window System, GDK supports 8 modifier keys and 5 mouse buttons.
177 * Since 2.10, GDK recognizes which of the Meta, Super or Hyper keys are mapped
178 * to Mod2 - Mod5, and indicates this by setting %GDK_SUPER_MASK,
179 * %GDK_HYPER_MASK or %GDK_META_MASK in the state field of key events.
