Juce 1.8 and treeview

[sylfeline]

Hello

The version 1.8 is good

but i have a problem with treeview. My treeview is link with a sorted string list, and when there is change in my list, i must close and open the parent node to see the change.

Is there another method ??

PS : sorry for my english, i’m french

Of course - you just remove all the sub-items and add them again when they change.

OK, it’s good

But now, i want to drag’n’Drop a item from a position to another position (like directory in windows explorer) What is the simplest method ?

i try several method, but i don’t succeed

Can somenone help me ??

That’s something that would be best if I built it into the treeview, though I’ve no time right now to do that.

You can use the drag-and-drop stuff to do it (like I do in tracktion’s project list). I’m going to post some new demo code soon with an example of drag-and-drop in it, so that might help.

I try the drag’n’drop functionnality in the 1.9 demo (openGL works fine !!). It’s very simple, but … i can’t do same things with my treeview

I create a class herited from TreeViewItem, but i can’t use “mouseDrag” … and when i try the “createItemComponent” function, i don’t suceed.
Is there a solution ??

Thanks for all

TreeViewItem can create custom components for each item in your tree, so you can use them to handle all the mouse dragging you need. Check out TreeViewItem::createItemComponent() for how to do it.
