Info

A reference to the text field instance is passed as a parameter to the onScroller and onChanged handlers by the event source. You can capture this data by putting a parameter in the event handler method. For example, the following code uses txt as the parameter that is passed to the onScroller event handler. The parameter is then used in a trace statement to send the instance name of the text field to the Output panel.The parameter is then used in a trace() method to write the instance name of the text field to the log file. my_txt.onScroller = function(textfield_txt:TextField) { trace(textfield_txt._name+" scrolled"); }; Parameters listener:Object - An object with an onChanged or onScroller event handler. Returns Boolean - Example The following example defines an onChanged handler for the input text field my_txt. It then defines a new listener object, txtListener, and defines an onChanged handler for that object. This handler will be invoked when the text field my_txt is changed. The final line of code calls TextField.addListener to register the listener object txtListener with the text field my_txt so that it will be notified when my_txt changes. this.createTextField("my_txt", this.getNextHighestDepth(), 10, 10, 100, 22); my_txt.border = true; my_txt.type = "input"; my_txt.onChanged = function(textfield_(xt:TextField) { trace(textfield_txt._name+" changed"); }; var txtListener:Object = new Object(); txtListener.onChanged = function(textfield_txt:TextField) { trace(textfield_txt._name+" changed and notified myListener"); }; my_txt.addListener(txtListener); See also onChanged (TextField.onChanged handler), onScroller (TextField.onScroller handler), removeListener (TextField.removeListener method) 614 ActionScript classes
_alpha (TextField._alpha property) public _alpha : Number Sets or retrieves the alpha transparency value of the text field. Valid values are 0 (fully transparent) to 100 (fully opaque). The default value is 100. Transparency values are not supported for text fields that use device fonts. You must use embedded fonts to use the _alpha transparency property with a text field. Note: This property is not supported for Arabic, Hebrew, and Thai. Example The following code sets the _alpha property of a text field named my_txt to 20%. Create a new font symbol in the library by selecting New Font from the Library options menu. Then set the linkage of the font to my font.Set the linkage for a font symbol to my font. Add the following ActionScript to your FLA or ActionScript file: var my_fmt:TextFormat = new TextFormat(); my_fmt.font = "my font"; // where 'my font' is the linkage name of a font in the Library this.createTextField("my_txt", this.getNextHighestDepth(), 10, 10, 100, 22); my_txt.border = true; my_txt.embedFonts = true; my_txt.text = "Hello World"; my_txt.setTextFormat(my_fmt); my_txt._alpha = 20; See also _alpha (Button._alpha property), _alpha (MovieClip._alpha property) autoSize (TextField.autoSize property) public autoSize : Object Controls automatic sizing and alignment of text fields. Acceptable values for autoSize are "none" (the default), "left", "right", and "center". When you set the autoSize property, true is a synonym for "left" and false is a synonym for "none". The values of autoSize and TextField.wordWrap determine whether a text field expands or contracts to the left side, right side, or bottom side. The default value for each of these properties is false. If autoSize is set to "none" (the default) or false, then no resizing will occur. TextField 615
