Dynamic Context Menu

3 posts in this topic

#1 ·  Posted (edited)

Hi all,

I'm working on a toolbar that has a user-customizable number of buttons that each need to have their own context menu so I got help from people here and this is what I've come up with. It works totally fine except when a normal context menu pops up over a button that has a context menu it'll pop up the button's context menu when you click the menuitem.

It seems to be registering a right click over the menuitem that i select - which triggers the custom context menu... any help would be outstanding :o

is there way to query whether or not a context menu is popped up? could I disable the custom context menu? I'm at a loss :D

try this test code and you'll see what I mean. Try right clicking on the title label and click on a menuitem that pops up ontop of a button

Test:

#include <GUIConstantsEx.au3>
#include <ButtonConstants.au3>
#include <WindowsConstants.au3>

Opt("GUIResizeMode", $GUI_DOCKALL)

;try and change buttons to activate on buttonUP so that dragging and releasing ontop of a button will work
;what about using static ctrls for buttons?...regular buttons are a lot simpler

When the secondary mouse button is pressed and the mouse is not over a button the context menu for the gui is shown. Then the secondary button is released but this event is queued until the gui context menu is closed which happens when you left click. I think that's what happens at least.

So if you use $GUI_EVENT_SECONDARYDOWN instead of $GUI_EVENT_SECONDARYUP it might work.
