• With the help of the police included in the tree control

  Hello

  I am trying to use embedded font to change the font family for a control tree but hopeless, I tested the police embedded with a label component and it worked well, but for the tree control, I couldn't succeed.

  Can anyone help with this, don't--what someone has any idea?

  You must embed the version "BOLD" to the police as well.

• Expand the tree after loading of dataProvider

  I need to develop all the item in the Tree control after data has been loaded using dataProvider.

  Here is the code

  public function loadTree (): void
  {
  cursorManager.setBusyCursor ();
  var conn: NetConnection = new NetConnection();
  conn.objectEncoding = ObjectEncoding.AMF3;
  Conn.Connect (this.) Meta.Gateway + ' web/gateway.php');
  conn.addEventListener (SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);
  var resp:Responder = new responder (onLoadTreeComplete, onFault);
  Conn.Call ("Client.Disk.GetTree", an RESP);
  }

  private void onLoadTreeComplete(e:*):void
  {
  trvTreeview.labelField = "label";
  trvTreeview.dataProvider = e;
  / / trvTreeview.expandChildrenOf(trvTreeview.dataProvider[0],true);
  cursorManager.removeBusyCursor ();
  }

  This only works if I call this function to any other event (such as a button click event) and not in the complete netconnection event.

  trvTreeview.expandChildrenOf(trvTreeview.dataProvider[0],true);

  How this could be done?

  Try to call validateNow before expandChildren or use callLater

  As I was mountain BIKING in the train a simple useful optimization appeared to me, saving a lot of redundant comparisons: use the iterator from the most to the loop as long as the start of the next loop index.  In addition, loop if the array is empty (you would think that it's automatic, but it turns out that an autoindexed for loop with an entry in a table of 4 x 0 will be still go 4 times, at least with the highlight performance enabled).  Here is an excerpt showing the change, which was not tested, but I think it's good:

  trurns that with a little change in the script and event that you expect, it works.

   
        function expandDiscloseNode(event){
                      var _tree = event.getSource();
                      rwKeySet = _tree.getSelectedRowKeys();

• Remote XML Dataprovider for the tree control

  Try to create a class of the tree instead of load application XML node list, to try to read from an external file called "nodes.xml". I tried to edit code snippets I've found from various sources and it's current iteration, I'm sure. Please advise on how to solve this problem!
  
  Note: In the XML itself I tried with and without the tags < mx:XMLList > wrapping, doesn't seem to work. Here is a link to a live demo: http://81.100.103.105/flex_dev/treeExample.html
  
  
  Thank you very much

  Alex, I was able to do the job of cleaning the XML file a little. Remove the XMLList and the? lines of xml, it looks like this:

  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  

  FWIW, if the XML is static (that is to say, won't come running), then you can consider using the tag mx: Model. It has fewer resources than the URLLoader and it cooked the XML code in the SWF at compile time.

• Tree control mode: Returns a validation event when the NORMAL value

  CVI 2013: I am writing a software to change the command tree modes based on the user's selection. I noticed that when the command is set to NORMAL, I got a "EVENT_COMMIT". Just for reference, I am using a custom control - group of Radio buttons, but the bug (I'm assuming that) is in the tree control are I forgot something?

  An application of Corrective Action (CAR) has been filed for this behavior. His number is 578618. You can monitor the condition of this CAR by checking the notes Readme or release new versions and checking the bug fixes section.

• How do you get the tag line in last-one click on a tree control?

  The API for tree controls is infuriatingly obtuse.

  In response to an event initiated by the tree control, I need to query the currently selected item in the tree and get his tag, so I can handle the element and its children. How this is done? I found the method of 'Set the tag', but there is no Tag «get» In fact, the only way to get the tag of any element seems to be through the 'Point to the column line' method, which takes a pair of coordinates entry component! It's confusing!

  Oh hell. Value of tree is the tag of the element currently selected. It's so easy that I never thought to look there for it, given the complexity of almost all other actions in the API.

• How do I open 'My Computer' with the tree of folders already signs?

  What I want, it's for when I open the application 'My Computer', to bbe able to see the the folder tree in the left pane, without having to click the Folders button on the toolbar. Some of our computers already do this because someone put in place, but the rest don't. We use Windows XP.

  TA, Paul

  Select the following automatically expand the trees:
  Go to the control panel in Windows XP

  Click on Start-Run-Control Panel and then double-click Folder Options.

  Select the view tab and under the Advanced settings: section.
  check the display Simple folder view in Explorer folders list and click OK.

  I think that's what you're looking for.
