问题 I have an AdvancedDataGrid which Im attemping to update with data from a web service that I poll once very 10 seconds. Im using a HierarchicalData object to provide data to the grid. The update seems to work fine, except that on each update, any nodes that were expanded are collapsed when the grid is refreshed. Stranger still, when I dig down into the bowels of the thing and look at the contents of the HierarchicalCollectionView that backs the grid, I can see that the openNodes property

问题 The Flex 3 docs are fairly basic. Can someone post a more complete example that uses the control's events? I'm still trying to get my head around ActionScript events. 回答1: You could find an interesting article concerning stateChange & playheadUpdate events on http://blog.flexexamples.com/2008/01/01/determining-a-videodisplay-controls-current-playback-state-using-the-state-property-and-statechange-event/ For a more complex example, take a look at the FXVideo component source code (in main unit

问题 I have a Canvas which has many components inside it and those again, have many components inside them. getChildren() returns only the top level children. What is the best way to retrieve all the children (children of children of children and so on). Well, I sorta know how to do this by iterating through the children, but the code is really messy. I'd prefer to use a nice recursive function. Has anyone written this before? Or is there a Util class to do this? 回答1: private function recuse

问题 I've found it's often useful to special case the first item in a drop-down menu (ie, an instance of Menu). For example, if I want to pick a color from the list provided by a web service: <mx:PopUpMenuButton id="colorSelelector" dataProvider="{colorsService.lastResult}" /> I might also want a special-case, which is "enter a new color", allowing the user to enter the RGB values for a new color which isn't in the list. For example: var newColor = { label: "Enter a new color", rgb: null }; Then
