rightButtonDown + popupmenu

[tsh73]

Set popupmenu to open on rightButtonDown

Menu opens, but selection doesn't trigger menu event.
As I checked,
leftButtonDown
leftButtonUp
rightButtonUp
works OK.

Found on Win10 in really big program.
It made me scratch my head for a while.

Try holding down the Right Mouse Button and Left clicking the Popup, that works for me.
Does not work if you release the right button then hold it down again to left click. Only goes to the label if held from original click.

I'm assuming this is the way LB is understanding/interpreting the rightButtonDown command, as is only firing if the right button is still down. Even though it works correctly for the Left button.

[tsh73]

Interesting. It does work as you describe.
Thought I not ready to jump thouhg hoops - just put that menu on rightButtonUp.

Still think it's a bug in LB

[Brandon Parker]

It definitely seems like a bug in LB...

It works when you step it through the debugger.

Well, it seems like some sort of race condition. I guess you can call it a bug, but popupmenus typically are opened on a mouse up event, not a mouse down event so that's a pretty slight bug.

[tsh73]

I don't really mind if
1) I indeed could use popup menu (it happens I could, just on buttonUp event)
2) it really should be documented (so I did't spend time banging on a wall)

FYI, I used it for this (can't help boasting):
Here LMB used to drag existing pieces, RMB - to add/delete piece

Indeed...

I think taking action on MouseUp is mostly desired because you can then just move away from something if you clicked on it inadvertently. Then the MouseUp event will not be triggered for the control you accidentally clicked.

Sorry, but it isn't documented because it isn't working as intended.
