GUICtrlTreeView Right Click Event

[dexto]

Trying to display a right click menu for an item in the Tree View.

Is there a way to detect what item in the TreeView was right clicked?

I am using GUIOnEventMode and closest I got to the goal was using:

GUISetOnEvent($GUI_EVENT_SECONDARYDOWN, "rclick")

in combination with

_GUICtrlTreeView_HitTestItem()

It didn't work since _GUICtrlTreeView_HitTestItem returned 0x000000

Thank you for any tips or just tell me that this is not going to work.

Thanks for looking into this. I did try it that way. With that method there is no way to find out what item was clicked unfortunately.

    $Char = Chr(64+$i)

    $myArray[$i][0] = "This element contains " & $Char

How about something like this?

That is what I thought at first. What it is doing for me is returning the last item selected with the left click.

Right, so if your right click generated a left click at the mouse position, then did what you want, you'd have the info and be able to use it however you want

Wow... To think I looked at it before you did mod it a bit by hardcoding the TreeView Handle and it works!!!

Thank you!!!

The only way to use mouse position to get handle of the item clicked that I know of is _GUICtrlTreeView_HitTestItem() that takes coordinates and get the handle. Only this it returned for me was 0x000000 that is nothing...

You're welcome, on a side note I believe credit belongs to rasim for the original concept:

Now that is think about it I might have not used _GUICtrlTreeView_HitTestItem(). I'll post if I find any easier solution for this. Thank you for the help!
