TextField._quality
Availability
Flash Player 6.
Usage
my_txt._quality:String
Description
Property (global); sets or retrieves the rendering quality used for a SWF file. Device fonts are
always aliased and, therefore, are unaffected by the
_quality property.
Note: Although you can specify this property for a TextField object, it is actually a global property,
and you can specify its value simply as
_quality.
TextField.removeListener()
Availability
Flash Player 6.
Usage
my_txt.removeListener(listener:Object)
Parameters
listener
The object that will no longer receive notifications from TextField.onChanged or
TextField.onScroller.
Returns
If listener was successfully removed, the method returns a true value. If listener was not
successfully removed (for example, if
listener was not on the TextField object’s listener list), the
method returns a value of
false.
Description
Method; removes a listener object previously registered to a text field instance with
TextField.addListener().
Example
The following example creates an input text field called my_txt. When the user types into the
field, information about the number of characters in the text field writes to the log file. If the user
clicks the
removeListener_btn instance, then the listener is removed and information no longer
writes to the log file.
this.createTextField("my_txt", this.getNextHighestDepth(), 10, 10, 160, 20);
my_txt.border = true;
my_txt.type = "input";
var txtListener:Object = new Object();
