Get reference to an image

[OnlyOne]

Hello,
i added a small jpg-iamge with cut&paste to the frontpanel.
How can i get a reference to this image to execute functions when someone clicks on this image?
I know the method of customizing a boolean-OK-button, but its to hard to make the image look like before when doing this.
Or is there an easy way?
Thx for your help

jpg dropped in the FP are just decorations and I can't remeber seeing any events for decorations.

But if you display the jpg in a picture control, that will give you mouse down, over, .... events.

While it's true that pictures come in as decorations, you could respond to the pane's Mouse Down, Over, etc. events, and interpret where the click occurred based on the coordinates. That would tell you if the click occurred in the picture, and if so, where in the picture.

Another option is to use a picture control. During the initialization of your VI load the image into the picture control programmatically. You can access the picture control's Mouse Down, Over, etc. events.

Sorry, Ben, missed your bit about the picture control.

"Sorry, Ben, missed your bit about the picture control."

No problem.

I thought about your approach first off but decided that by the time we find the proper decoration, get its bounds, etc, that it would be alot easier to just use a picure control. It does not have to be loaded dynamically. It could be asimple as making the jprg the default of the picture.

You can also use a Button with the picture as a decal and the button transparent.  Then use the buttons events.

Sorry didnt finish the read, ignore the button approach.  It would be nice if decorations had events and properties.

It would also be nice if you could right click a decoration, and create a
reference. And if you could give it a label.

Wiebe.


(For OnlyOne:
If you want to get a decorations reference, use the following properties:

Panel (returns a panel ref)
Decorrations (rturns a list of all decorrations)

Use an index array to get the right one
)

Yes without being able to name and reference decorations you are forced to use picture controls in labview.  Maybe a simple front picture build into the vi could allow users to decorate the front panel programatically.

I thought of Wiebe's, but was a bit afraid to post because I ve not done much with decorations programatically though.
