commit 7a59b443eefac87354802c4e7117f9e61dbeee9d
Author: Carlos Garcia Campos <cgarcia igalia com>
Date: Mon Feb 14 12:44:17 2011 +0100
Add GtkWidget::press-and-hold signal
Press-and-hold signal is emitted when the mouse button is pressed for a
given amount of time, specified in the new "press-and-hold-timeout"
GtkSetting. It's commonly used in mobile platforms to emulate a right
click to show a context menu. This patch is based on previous patches by
Kristian Rietveld and Danielle Madeley.

+ * GtkSetting); during this time the mouse is only allowed to move a little
+ * bit (not past the drag threshold), else the press-and-hold operation will

+ *
+ * From the above passage we can distill three actions for which this
+ * signal will be emitted: query, emitted when the mouse button goes
+ * down; trigger, emitted if the mouse button has been kept down for the
+ * specified amount of time and movements did not pass the drag threshold;
+ * and cancel, emitted when the press-and-hold operation has been terminated
+ * before the trigger action has been emitted.
+ *
+ * For query, @action will be set to %GTK_PRESS_AND_HOLD_QUERY, @x and @y
+ * will be set to the cursor position.
+ * A return value of %FALSE means no press-and-hold action should occur
+ * for these coordinates on the given widget, when %TRUE is returned
+ * a trigger action may be emitted later on.
+ *
+ * The trigger action is emitted by setting @action to be
+ * %GTK_PRESS_AND_HOLD_TRIGGER, the @x and @y coordinates are set to the
+ * cursor's current location (this includes any movements made between
+ * the original query and this trigger) and @keyboard_mode is set to
+ * %TRUE if the trigger was initiated by a keyboard action, %FALSE
+ * otherwise. In this case the return value is ignored.
+ *
+ * When @action is %GTK_WIDGET_PRESS_AND_HOLD_CANCEL, @x and @y are both
+ * undefined. The return value is ignored too as
+ * this action is only there for informational purposes.
