My front panel blanks while I use the panel bounds property

[kc64]

When I execute the PanelBounds property of the front panel, the panel seems to blank for a brief moment allowing me to see the desktop and then reappears.  I am wondering how to prevent this behavior or approach the problem in a different way.  Any ideas?

Hey,

What version of LabVIEW do you have? Can you post the code? I will see if I can reproduce this.

Here is a demo version that demonstrates my issue.

Open the dummy user interface (UI.vi) and the main program (Main.vi).  Run Main.vi.  See how the UI flashes when changing areas of interest.  I can see the desktop during the transition since the front panel blanks.

Tip:  Close the front panel with Alt-F4 since it will be full screen.

Hey kc64,

This looks like a possible bug. I am trying to narrow down the code so I can submit it to R&D.

Any update on this issue?

Hi KC64,

I have filed a CAR to R&D for this issue. The CAR number is 176286. I will let you know if they have any suggestions for work arounds. You can also check future releases to see if this issue has been fixed. This would show up in the "bug fixes" section, under the CAR number.

Instead of using the Panel Size, try using the Pane Origin.  It effetcively does what you are doing and does not cause the screen to flash.  I modified your demo to show this.  Note, I didn't properly close all references in your modify code, which you will want to do.

Thanks, Matt!

This worked great.
