Layout issues after SlicerT UI update

master after and including 7d35d42

Bug Summary

There are some issues with the instrument layouts after 7d35d42

The ones I've noticed are LV2 instrument layouts. I'm unsure if the cut off FX chains in #7508 are also from this commit.

Steps To Reproduce

• Drag a Caps - C* Fractal into a project and open the instrument

Caps LV2 - C* Fractal (before and after)

Sorry, I don't have a machine to test with at the moment, but looking at the code this is probably caused by this line here, where it seems like height and width are in the wrong order.

subWin->setMaximumSize(m_instrumentView->maximumHeight() + 12, m_instrumentView->maximumWidth() + 208);

Could you maybe quickly change the line to this to test it? If you can't I'll do it in a few days.

// fixed line
subWin->setMaximumSize(m_instrumentView->maximumWidth() + 12, m_instrumentView->maximumHeight() + 208);

If this doesn't fix it I'll look trough the code a bit more later on.

I'm unsure if the cut off FX chains in #7508 are also from this commit.

From my investigation, I can confirm that it is. Reverting that PR fixed the bug.

I have rolled out a proper fix for the effect view glitch in #7511

[Rossmaxx]

I have pushed the fix for this bug too in my PR, but haven't tested that one because I don't have any lv2 plugins yet.

Just chiming in, the views of other tabs in the instrument view are also horribly stretched

[michaelgregorius]

IMO the instrument window is in dire need of an overhaul anyway. By default they are very small and crammed:

So it would be good if the instrument window had a larger default size so that the layouts of the different tabs have space to "breathe". The layouts should also be adjusted so that they have a reasonable resize behavior.

Having the envelope resizable is a good thing in my opinion as it allows for more precise editing. It just looks ugly because it uses pixmaps to render its background.

If we are planning on overhauling the instrument window and making it larger, we should consider adding space for a Pin Connector button, preferably near the Channel spinbox. (See: #7459)

Mentioning #7524 here, which might fix some of these issues.
