autorun application in flex

Question

I found an application that read the information about you webcam. The thing is that when the application start you need to click on it to view your stats.

I have now connected the application to a button that animate the mx:list i created, But anyhow I need to fist click on the list to generate the output on a mx:label.

Any Ideas how I should do to just click on my show button to autorun camera stats.

Thanks

Answer 1

First, I split your function in two:

private function list_change(evt:ListEvent):void {
    var tList:List = evt.currentTarget as List;
    populateCameraInfo(tList.selectedIndex.toString());
}
private function populateCameraInfo(cameraName:String):void {
    camera = Camera.getCamera(cameraName);
    textArea.text = ObjectUtil.toString(camera);
}

Next (and I'm assuming you want the list to be visible to start with):

<mx:List id="list"
         dataProvider="{Camera.names}"
         width="200"
         change="list_change(event);"
         hideEffect="{ZoomRotateHide}" 
         showEffect="{ZoomRotateShow}"
         selectedIndex="0"
         creationComplete="populateCameraInfo('0')"
         />

So that way the first item is always selected.
