Modifying Pane Origin doesn't affect scrolling.

[ShockHouse]

I'm trying to make an application that allows a user to modify the screen size and still be able to control everything. Most of this is done by having a main vi that has subpanels that get filled up with vi's. All of this is built upon actor framework.

I don't want any elements on the front panel of all the vi's to change size. The only thing I want is for the position of the vi within the subpanel to change so that it is always centered. I've achieved this by taking the size of a Pane, and setting the origin to the center based on the rectangular area of all the controls. This part works great. I programmatically turn on the scroll bars if the vi won't fit in the subpanel so the user can still get to everything.

The problem comes when a user uses the scrollbar on a subpanel. Since the inserted vi is centered, because of the origin change, I would hope the scroll bar would take that modified origin and change it. Instead it seems like whenever I use the scrollbar it takes the default origin, instead of the one I set. This causes my vi's within subpanels to be thrown to one side of the window, instead of remaining center. You can see that behavior in the gif I attached.

Anybody ever ran into this issue and know a way around it?

I've look up some methods in property nodes that could help you:

-Property nodes: VI server class

                              >Keep window proportions 

                              >Panel Bounds

                              >Window Bounds

                              >Resizable

If you are not going to set other controls or indicators in your front panel you could set a specific window size to prevent the reference problem. By the way, you can always look up for the functions of these methods on the web.

Hope this help you.
