Tab Sizing <> Controls size with tab

[Norm Kirchner]

*Disclaimer* So far from a full implementation, but I wanted to get this into the wild to let you all have fun with it.

I ran into a situation that pissed me off recently.

I had a tab control that had a different graph on each tab. This tab was in a pane that I wanted to be re-size-able.

Since LabVIEW does such a shitty job at helping us with this, I made a 'Brat VI' to help me with the process.

Attached you will find the Brat and a piece of demo code.

Basic assumption and requirements

*Tab is not set to auto-grow (I don't handle shrinking tab and auto grown will cause tab to not maintain size w/ pane)

*Tab is set to size with pane

* Types of controls that are resized are currently limited, string, graphs, sub-panels, decorations, boolean (because I use the 'Many Cast' design pattern, adding more is not a difficult task)

* Because this maintained sizing will only work while the VI is running, the Brat is bi-modal in a "Use cached Margins" or "use Saved margins" mode (see video for rational)

Well, we discussed it here in the past, although I have to admit I never had the need to use something exactly like this in a production app, so all the stuff there is just quick and dirty experiments.

I haven't looked at the entire discussion there now, but if memory serves, the two interesting points you can find there are the basic difference in calculation (it was the ratio of the control relative to the panel as opposed to constant margins, although I'm not sure what the implications of each are) and that there is an example of a generic (but undocumented) resizing method (which is probably the same code LV uses when the user manually resizes a control).
