mouseDownScript
Usage
the mouseDownScript
Description
System property; specifies the Lingo that is executed when the mouse button is pressed. The
Lingo is written as a string, surrounded by quotation marks and can be a simple statement or a
calling script for a handler. The default value is
EMPTY, which means that the mouseDownScript
property has no Lingo assigned to it.
When the mouse button is pressed and the
mouseDownScript property is defined, Lingo executes
the instructions specified for the
mouseDownScript property first. No other on mouseDown
handlers are executed, unless the instructions include the
pass command so that the mouseDown
message can be passed to other objects in the movie.
Setting the
mouseDownScript property performs the same function as the when keyDown then
command in earlier versions of Director.
To turn off the instructions you’ve specified for the
mouseDownScript property, use the statement
set the mouseDownScript to empty.
This property can be tested and set.
Example
In this statement, when the user clicks the mouse button, the playhead always branches to the
next marker in the movie:
the mouseDownScript = "go next"
In this statement, when the user clicks anywhere on the Stage, the computer beeps:
the mouseDownScript = "if the clickOn = 0 then beep"
The following statement sets mouseDownScript to the custom handler myCustomHandler. A
Lingo custom handler must be enclosed in quotation marks when used with the
mouseDownScript property.
the mouseDownScript = "myCustomHandler"
