This worked in LabVIEW 8.0 but does not work in LV8.2.

If you right-click on a control and select "fit control to pane" then you resize the panel, the control doesn't resize in real-time with the panel scaling. It only resizes after you have finished resizing the Panel. The proper behavior is to have the control resize dynamically as you resize the VI front panel.

This has been submitted to NI support.

Response back from NI support:


So, my request from the LAVA community: If you care to change this back to the 8.0 behavior then send a feature request to the indicated link. The best solution in my opinion is to be able to select between both behaviours.

I would argue that this is a bug. I have come to expect the behavior that Michael mentioned (fit as you drag) in LabVIEW 8.0x. If this this not a bug, then where was it documented that this was changed? I don't remember reading anything about it in the upgrades notes. If there are 2 possible behaviors, then I would expect to be able to access both programatically. In my opinion, resizing the windows content after you have finished resizing the Panel is the wrong behavior. I can not, on the top of my head, think on any applications that follow this behavior in windows.

I think I can see the logic about doing it the new way in order to avoid extensive UI redrawing during a window resize, but agree that the old behaviour was better. However it may have been a glitch in 8.0 because as far as I remember did earlier versions also not dynamically resize the front panel objects during window resize.

Unless I had only one control that needed to resize and nothing else that needed to move on the front panel I have always done this so far myself in the panel resize event case and that gives a very smooth effect, although I do need to test that this still works in LabVIEW 8.2.

The "funny" thing, is that all LabVIEW native window (read here: not build in G such as Error List, Profiler...) that can be resized express the expected behavior (Fit as you drag)...'
I also have tried to use the resize panel event, and while this work, this does not look as good as doing it natively. There is alway a small delay and your control size end up lagging behind and in my opinion this too does not look good.

I like the older behavior, but if you have several panes, locked controls to maintain proper GUI layout, etc, I can see where the redraw might cause flickering, etc, especially on slower machines.

Funny, but on one of my machines (LV 8.2.1, Win2K) I do not get this behavior, only a window outline, then eveything snaps into place on one resize. I'm obviously missing something simple here.

Just an FYI on this topic. Some good news. Here is some insider info which confirms that this will be resolved in a future release (don't ask where I got this from).

Sweeeet!

Nice note on the FYI Michael.

And as I suspected, my WinXP machine exhibits the exact behavior that Michael describes, it's only the Win2K that shows only the outline.
