ActionScript 3.0 :: Trigger Event From Scrolling Textbox?

May 12, 2010

I'm using AS3, loading external text into a text box. Let's say the text box shows 20 lines of text. Is there a way to trigger some kind of action, for example, changing an image on the stage if the user scrolls the text and line 30 appears in the textbox? Kind of like a cue point for scrolling text.

ActionScript 3.0 :: Knowing When To Trigger Scrolling?

Oct 23, 2009

I have a dynamic input textfield and I have a scrollbar successfully scrolling the text. As soon as the textfield receives focus the scrollbar tweens into position. I would like to have the scrollbar tween in only when it is needed, which of course would be when the texfield has one more character than it can display in the viewable area. Is there some sort of event I should be listening for that would tell me that the textfield has grown past the viewable area?

ActionScript 1/2 :: Using Event Listener To Trigger Text

Feb 2, 2012

I am using the following code to create the quick word for a translator who is doing a live translation of a chat.

the word is succesfully generated, only problem is, it deletes all the other text in the text box as well. Is there a way of making a keyboard shortcut which just adds that text on the same row I am on? Otherwise I am also happy to settle for a button which generates this text as long as it does not delete the other text in the text box.

This might be an easy one for you DataGrid experts out there. I following an example for adding rows to a DataGrid dynamically from within a row

My tweak that I am trying to acoomlish, is to have a custom itemEditor that is a form with two TextInputs and an OK button. For the life of me I can't get that button to trigger the DataGrid's itemEditEnd event where I have some processing before I call destroyItemEditor. I tried dispatching the event myself directly but got a strange error in DataGrid's updateDisplayList saying editedItemPosition was null (editedItemPosition.rowIndex).
