element.height
Availability
Flash MX 2004.
Usage
element.height
Description
Property; a float value that specifies the height of the element in pixels.
Note: Do not use this property to resize a text field. Instead, select the text field and use
document.setTextRectangle(). Using this property with a text field scales the text.
Example
The following example sets the height of the specified element to 100:
fl.getDocumentDOM().getTimeline().layers[0].frames[0].elements[0].height =
100;
element.left
Availability
Flash MX 2004.
Usage
element.left
Description
Read-only property; a float value that represents the left side of the element. The value of
element.left is relative to the upper left of the Stage for elements that are in a scene, and is
relative to the symbol’s registration point if the element is stored within a symbol.Use
document.setSelectionBounds() or document.moveSelectionBy() to set this property.
Example
The following example illustrates how the value of this property changes when an element is
moved:
//Select an element on the stage and then run this script
var sel = fl.getDocumentDOM().selection[0];
