Get width context menu before displaying [SOLVED]

[nend]

Is it possible to get the width of a context menu before showing it.
I need it to aligned right widht the end of the window.
The text in the menu is multi language and there for not possible to set the width in the code.

The first image is how I get it and the second is how I want it to have it.
I think It is possible but I can't find a way to do it, I've search more than 40 min on google but no luck


I hoop some one has a good idea.

Create it outside the monitor ( say, -100,-100 ) and measure it. Then, any time you call it, since is going to be the same size, and the size is already known, position it accordingly.
( just an idea but w/o coding it I would not know. Just an idea )

Or find a way to change the style to allow aligning the context menu to the "Right" side (from button) depending what the main window has their

Better yet Post a reproducer to tell what option are available

@Deye

Thanks when you mention to change the style that made me to find the solution.
I'd use _GUICtrlMenu_TrackPopupMenu with $iAlignX set to "2"
