Is it possible to know when you double click a node? I tried the onCollapsing/onExpanding, but it doesn't work if the node doesn't have other nodes inside. I also tried to use onDblClick and detect what you've selected, but it doesn't work properly since if you press something then double click in the back of the TreeView, it will still trigger the event.

no, there is no method right now. For now demand that the user makes sure he doubleclicks on an entry

One dirty trick around it is to set the "HasChildren" property of every node to True(using code), even those with no childnodes

Thank you, but I have another question. How exactly do you set a multi-lined string to a Memo? The setText method from Strings class says :

setText() : Sets the strings of the given strings object to the given text (can be multiline)


But there doesn't seem to be any argument to that method. I don't know how to set the Memo's Lines to my specific string?
