Flex :: Get The XML Parent Of A Selected Tree Item?

Jan 27, 2010

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.

Jan 11, 2010

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?

Flex :: Toggling States - When Other Item Is Selected The First Item Does Not Change Its State?

Apr 26, 2011

I have used states in my application.The thing is I have made the first item in my list to be selected. so I gave like this,

if(itemIndex == 0)
this.currentState="selected";

this works fine.The problem is when other item is selected the first item does not change its state,it remains in the selected state until its clicked.My code looks like this,

<s:BorderContainer id="outerCont" width="275" height="100" borderVisible="false"
backgroundColor.normal="#3D3C3C" backgroundAlpha.selected="0.1"
backgroundColor.selected="{data.color}">

My states are like this,

<s:states>
<s:State name="normal" />
<s:State name="hovered" />[code]........

Flex :: How To Drop Something Into A Tree Item

Jan 15, 2010

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.

Flex :: Get Item By Index In A Tree Control?

Jan 20, 2010

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.

Flex - OS Like Behavior When Edditing A Tree Item?

Jan 20, 2010

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

Mar 9, 2010

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?

Flex :: Access ItemRenderer Of A Selected Item?

Feb 3, 2010

I have a TileList with thumbnail images. Under each thumbnail images I display the name of the image. I want to build rename functionality. So under the TileList is a "Rename selected image" button.

When this button is clicked, I would like to change the state of the itemRenderer component. The label underneath the image will change into a TextInput so that the user can type a new name. This is much like the Windows rename file functionality.

How can I access the itemRenderer of the selected image? How can I make it happen that it listens to the click event of the Rename button?[code]...
