Some people asked about changing the default editing behavior of a Flex 3 Tree control so that item editing starts on a double-click event instead of the default single click.
- a new name: DragController
- drag and drop multiple items at once if multipleSelection is set to true for a component
- added the following methods to the DragEvent Object:
- the methods were renamed to fit Macromedias naming conventions for methods
- i lowered the addReference restriction that both components have to be UIComponents. Now only the source has to be an UIComponent and the target suffices to be a MovieClip.
- added a veto method for the “drag_start” event. So user can decide on this Event if he would like to allow dragging of this specific item.
- added an onDropData method besides the Event handlers. So you can assign this method directly to a defined target component.
- added flags similar to DragAndDropTree component. These are:
- DENYDRAGFOLDER (only tree component)
- DENYDRAGITEM (only tree component, as i makes no sense for other components)
- DENYDROPINTOITEM (only tree component)
- DENYDROPINTOFOLDER (only tree component)
- DENYDROPINTO (only tree component)
- DENYDROPINBETWEEN this option disallows setting a specific target index position and will add the item at the end of the List, DataGrid, Tree
- removed some bugs concerning Focus on Component and selectedItems. But i am not sure if there aren’t some left due to Flash’s strange Focus mechanisms. (sure, I still haven’t understood the focus mechnism of MM components)
There’s also a very comprehensive help of the component (just look in the F1 flash help panel)
Yes, this is another drag and drop tree component 🙂
It was a log I wanted to extends the built-in Flash mx 2004 Tree component in order to allow drag and drop operations.. but time was always my enemy.
I was lucky that i need one for work.. i look around and i founded some cool other similar components, but i wanted to be able to do it by myself 😉
It just extends the base Tree component and you can set some drag and drop rules, just costants..
for example, i set these costants to be used:
they can be used in combinations:
myDnd.dragRules = TreeDnd.DENYDRAGFOLDER | TreeDnd.DENYDROPITEM
in this way you cannot drag a folder, only leaf nodes, and you cannt drop the dragged item into a leaf node, only into a folder or before/after another leaf node…
