TreeView Select Item On Right and Left Click

[Yonekura]

Hello, I pretty sure this is a simple question. I have a treeveiw with a context menu. When I left click to select an item and then right click to pull up my context menu everything works fine. However, when I right click on different item, it appears to be selected, but it is not. If I let off the right click button without choosing on option in my context menu it springs back to the previously selected item. If I choose an option from my context menu it acts as if the previously selected item is currently selected. It's like focusing on the item, but not really selecting the item when I right click.

So how can select the item on a right click instead of just focusing? I am not using and event loop but GUICtrlSetOnEvent to determine when and item clicked or changed.

Or is there a way to disable a focus change on a right click because that would work too.

Post your code or a reproducer.

Okay here is some code I quickly wrote up that reproduces the problem.

Well after reading around I think I found a solution. I did not find any functions that did what wanted at  GuiTreeView Management. So I looked around and ended up Creating an event with GUIRegisterMsg of type $WM_NOTIFY. After finding similar problems and their solution code.  However, it does seem a bit hacky to me though? Any other better solutions?

I have waited a few days, and I have not heard anything back. Is what I have a fine solution?

[careca]

The issue is that the right click is not detected, tried many functions, but they all depend on the LEFT click first to work.

[Yonekura]

Okay well if that case. I guess I will stick with what I have. Unless someone has some major improvements.
