| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: dialog-item
Returns the value of the on-mouse-out event handler for the
argument control. The value of the on-mouse-out property should be a
function object or a function name (a symbol naming a function). This
function is called when the mouse cursor is moved out of the control's
rectangular area. on-mouse-out may be nil
if no function need be run.
If an on-mouse-out function is supplied, it should take three arguments, which are (1) the control and (2) the mouse-button-state at the time the mouse moved into the control, and (3) the window that the mouse moved into from this control. The return value does not matter.
Many functions take a mouse-button-state argument. This argument is a
single integer that tells what combination of mouse buttons and shift
keys when the message that is being handled occurred. Each mouse
button or shift key is represented by a constant that has a single bit
flagged, and so bit tests on the button-state argument can be used to
tell whether particular mouse buttons or shift keys were down. The
particular constants are left-mouse-button
, middle-mouse-button
,
right-mouse-button
,
first-x-button
(see *ignore-mouse-x-buttons*
),
second-x-button
(see *ignore-mouse-x-buttons*
),
shift-key
,
control-key
, and
alt-key
.
