Problems with Mouse Down event for a picture control embedded in tab.

[tuck]

I noticed that when trying to get a Mouse Down event for a picture control that the Mouse Down will not be 'fired' if the picture is embedded in a tab control. It also appears that this problem exists for other controls (I only tested a slider in addition to the picture). It isn't much of an issue for me now as I can just poll the mouse property of the picture control, but the Mouse Down event has information that I may want access to in my next software revision (button pressed, and Alt mod). I could do that by handling the Mouse Down event for the tab itself and checking to see if the the mouse property isn't -1, -1 for the picture, but that seems a little bit too kludgy (sp?) to me and wouldn
't address the issue with other control types. Any chance of this being addressed by a patch sometime in the next couple of months???

Hi Tuck,

This is devistating! Your example demonstrates the issue well on the machine I am using.

I have NI support looking into this issue as I write.

Service request # 468881.

As soon as I hear more I will share.

Thank you for sharing this example.

This "feature" has been confirmed by NI.

I will post more when I am able.

I am having the same problem, any chance there is an answer to this problem yet (since it is now 8/2004)?!?

The problem I reported above was in LV 6.1.

As a work-around, I used the mouse down on the tab control and did the math to decide if the picture was clicked.

I have been told that this was fixed in LV 7.0. I can not confirm.

You could call NI and ask about the service request number I cited above.

I hope this helps,

Ben
