Member Function Documentation

virtual int KrPushButton::IsMouseListener   [inline, virtual]
 

IsMouseListener returns whether this is a mouse listener or not, and which buttons are listened to.

A return value of 0 is no listening. Else it can return an OR mask of the buttons ( LEFT_MOUSE, RIGHT_MOUSE, MIDDLE_MOUSE ) it wants to listen for mouse clicks.

The simple case is to only listen to the left mouse, in which case return LEFT_MOUSE (1). The click messages can then be treated like a boolean for the left mouse (1 is down, 0 is up.)

Currently, with version 2.0, only the LEFT_MOUSE is supported.

MouseIn is called when a mouse moves in to the widget. The 'down' parameter reflects the state of the left mouse button. The 'in' reflects whether it is moving to the widget (true) or away from the widget (false).

MouseMove reports when the mouse moves over this widget.

MouseClick is called when the mouse is clicked on this widget. The 'click' param will have a single value (not OR mask) of LEFT_UP, LEFT_DOWN, RIGHT_UP, etc. with x and y coordinates of the action.

In the simple case that you are only listening to the left mouse, the parameter will be essentially a boolean: 1 for the left mouse down, 0 for the left mouse up.
