I'm working on a tree component using a XMLLIST as a data provider.
<list>
<menuItem label="Home" menuItemId="1" >
<menuItem label="Info 1" menuItemId ="4"></menuItem>
[Code]....
I need to select a nested node by the property 'menuItemId' without knowing the index.For example, select the item with the menuItemId 4.
I have this datagrid:
<mx:DataGrid id="dgCompetenteN" includeIn="Test" left="10" right="472" top="69" bottom="149"
dataProvider="{colCompetente}" editable="false">
<mx:columns>
[Code]....
What I want to do is, when I select an item in the datagrid, the selected item of the dropdown should be the correct one (the one which has the field idCompSuperioara equal to the third element in the selected datagrid row).
I want to be able to select an item from my list component and fire a function directly related to selecting that item. list is called "tidlist" function is "selecttid(n)" the "n" needs to be replaced with the index number... so if run my swf and the list component displays my items... when i select one (the third one for example)... i want to fire "selectTid(3)".... cant seem to grasp.

I'm using a flex combobox component in Flex builder 3 with sdk 3.4 and I'm trying to use it to expand and select the tree node that the user selected in the combobox component on the change event. However, I'm getting an error when I go to assign the combobox seletedItem to the tree selectedItem. Can you please help? What am I doing wrong?

I'm trying to modifty the Flex Tree control to allow a user to select multiple items by just clicking each of the desired elements (ie I don't want them to have to press Ctrl or Shift). If the user clicks a selected item a 2nd time, it will deselect it.
View 2 Repliesi have a Flex tree control and im trying to select a tree node 3 levels down right after the dataProvider is assigned with a collection object like the following.basically treeItem1, treeItem2, treeItem3 are the nodes in the tree and treeitem3 is a child of treeItem2 which is a child of treeItem1. Assume these treeItem(1,2,3) are referenced correctly from the collection items.
my problem is that if i wait for the whole component to load completely then select the nodes, it open/select/scrolltoIndex correctly. However, if i were to select the node right after the dataProvider is assigned, then it doesn't even open or select (basically the this.treeService.selectedItem is always null).
this.treeService.dataProvider = oPricingHelper.getCurrentPricingSercicesTreeSource();
this.treeService.expandItem(treeItem1, true);
this.treeService.expandItem(treeItem2, true);
this.treeService.selectedItem = treeItem3;
this.treeService.scrollToIndex(this.treeService.selectedIndex);
I just read a comment at FlexExamples: One thing to note about the tree is that it is really just a list in which items are displayed. What that means is, you can't really drop somthing "into" folder unless the folder is open. Even in that case the user experience isn't quite right. So try moving everything out of one of the folders and then collapse that empty folder. If you drop something "on" the folder, it actually winds up between the target folder and the one below or above. This is indicated by the black line showing up as you move the mouse over the folders. If you "open" the folder (the only way to tell it is open is by the arrow) and then try it, you end up with an additional drop zone that is basically the bottom half of the opened, empty folder. This is also indicated by the black lines position.
It would be better if the middle section of any item could always be the drop zone for "add to this folder" and the top and bottom edges could be for dropping above or below respectively.I've just come to the same problem. Has somebody already managed this problem? In my case, I have dragMoveEnabled in the tree and offer the ability of dragging the tree items. But it is impossible to drag an item into another item that is empty. You can only drop the dragged item above or underneath an empty item.
How can I use multiple item renderers in mx:Tree depending on item's depth/level in tree?For example. For the first level items I want to use label with button and for second level items combobox
View 2 RepliesI'm using the tree component for a little Windows Parody I'm making. In my .fla, There's a tree component that loads an external XML file. I can't figure out how to add custom icons to my component, though.I know it's possible to set the icons for just the default folder and file icons, but since it's a Windows Parody, there'll be different icons for different file types, folder types, etc.In other words, I'd like to have a different icon for every item in my Tree component.
Here are the contents of my XML file:
<node>
<node label="Desktop">
</node>
<node label="Documents">
[code]....
Also, I don't need to have an XML file loaded. If there's an easy way that does it all within Flash, please tell me. I just need to be able to handle events from the Tree.
I have created a MyTreeItemrenderer extending TreeItemrenderer.
However, I do not want any label, folder, disclosure icon nor icon. I want to dispaly every node of the tree with my own graphic like eg: a line, round image etc.,
I'm doing a drag and drop operation on a tree using some help from Adobe's quick Starts:[URL]
The code suggested is roughly this:
var dropTarget:Tree = Tree(evt.currentTarget);
var i:int = dropTarget.calculateDropIndex(evt);
myTree.selectedIndex = i;
[Code].....
EDIT: I forgot to post that my current workaround is setting the selectedIndex = -1 after I get my node:XML. I'm afraid that if something bogs on the processor the user may see it select then deselect.
I have a Tree Control inside my Flex Application which I want to edit on a doubleclick on a tree item. I found the properties doubleClickEnabled="true", doubleClick="startEditMode()", and editable="true". With these functions I can detect a double click and I can change the editable property to true based on a double click. The problem is that after I double clicked on a Item i have to click once more to really enter the edit mode. That doesn't seem to be intuitive at all

I have a XML based Tree Control. The XML Structure is recursive, so the children's can have the same Element as the parent. I now want to let the user add and remove the elements. Do do so I need to get the parent element of the selected Item. Following code I already collected together:
var selected:XML = treeControl.selectedItem;
parent.insertChildAfter(selected:XML, newElement);
I just don't know how to get to the selected parents node as there is no such method like treeControl.selectedItem.parent.
I have a tree control and I want to give the user the ability that he can move up and down the element he just selected with a up and a downbutton. The tree gets generated from XML. I managed to insert the selected item a second time at a other place, with the following code:
var parentXML:XML = XML(containerTree.selectedItem).parent();
var upperItem:XML = topContainer.source[containerTree.selectedIndex-1];
parentXML.insertChildBefore(upperItem,XML(containerTree.selectedItem));
but then I have the item there twice in the List. How can I remove to reinsert it?
my renderer contains a canvas in it, i add some title-window, every time i see my tree previously added Title-Windows are visible, i want to access each n every item in tree and remove previosly added all windows from the rendere. how access all the item renderer in AS3 ?
View 1 RepliesI have an mx:tree with with TreeItemRenderer as below.
Parent1 (Delete | Rename)
Child1
Child2
Parent2 (Delete | Rename)
Child3
Child4
Delete and Rename are link buttons
Now when i click Rename a popUp should be shown like
OldName : Parent1(Text Input showning present Name)
Enter New Name: Parent1NewName(Text Input for entering New name)
OK | CANCEL Buttons
Afetr Entering the new name,click OK,popup should be closed and need to get the value in the treeItemRenderer.
I have the logic to rename the Parent1 in TreeItemRenderer and also I m able to get the Parent1 in the popup OldName TextInput.But after entering the new name i m not able to get that new name in the TreeItemRenderer.
How would i go about randomly selecting an array item?
View 3 Repliesi was in situation that tree is re-using my custom item-renderer.. is there any method or way around we can stop tree to reuse.. and always create a new item-renderer for new item..
View 1 RepliesI have created a custom item renderer for the tree, i have added some children in create children function, my problem is that sometimes i need to show these children and sometimes i don't, depending on clicking on a button which also i have added at create children, the problem is that i had to create the item even if i don't want it to be visible, and removed it by making visible false, and this costs a lot of memory, i have tried to create it at buttons click listener but when scrolling the child disappears, and it may appear again if i keep scrolling up and down.. i am trying to add the child just when i need it to be visible, is this possible or i have to create it on child creation method?
View 1 RepliesI have a Flex (3.5) Tree with drag & drop support, but the problem is that after I drag an item (node) and drop it, it's supposed to be the selected item in the tree, but for some reason it's not highlighted.
View 1 RepliesI've got a tree component which works great, but I'm trying to add an item at a particular location (immediately after the item they select) into the tree. The problem is that I'm trying to add an item within a branch. I'm using myTree.getDisplayIndex(myNode) to get the position within the tree, but it gives the location relative to the entire list, but I need to get the position relative to the parent (which is what myNode.parentNode.addTreeNodeAt is trying to write to)...
View 2 RepliesI'm working on an 8-user app that runs over a wi-fi network using an XML socket. All of the hardware is located inside a medium sized room in a school building.At the start of the app, each user can select 1 role from a pool of 8. However, the socket connection runs at less than realtime, probably because of latency from the wi-fi, so it's possible for two users to make the same selection at the same time. How would I prevent this?

In Flex 4, I have a Spark List component with item renderers. I would like to select an item in the List by clicking on it, and deselect it also, by clicking on the same selected item. Like an on/off switch.
My item renderer has the following states:
<s:states>
<s:State name="normal"/>
<s:State name="hovered"/>
<s:State name="selected"/>
</s:states>
so I tried to add a click event listener to the item renderer with:
private function selectUnSelect():void {
if (currentState == 'selected') currentState = 'normal';
else currentState = 'selected';
}
with an awkward behaviour... where the item stay selected even after clicking it again in the selected state.
Think of using the List component without the Command (on mac) or the Control button on windows.

I have a Flex tree with an ArrayCollection as data provider. The collection holds an array of CategoryVO objects. Each object can have another array of CategoryVO objects inside it's "child" attribute. This way the tree displays the data correctly. Now I want to get the parent of a specific item, e.g. tree.selectedItem. Using XML as data provider the item parent is avaiable thorugh the parent() method. But I can't convert my data to XML. How can I get an item's parent? Perphaps using the tree's dataDescriptor?
