2025.30960 Creating COMPs with python

Bugs
1

Hi, here is an example on
2025.30690 Windows 10

b = op('/').create('baseCOMP')
cOp = b.create('buttonCOMP')
ui.panes.current.placeOPs([cOp])

As a result - buttonCOMP panel is not working + ‘layout dependency loop detected’ warning.

Best,
Alex

The slider does not update the position in the ui sladerCOMP

Noticed that triggering panel visibility + forcing cook solves it
For example, this works fine:

b = op('/').create('containerCOMP')
b.openViewer()
cOp = b.create('buttonCOMP')
b.cook(force = True, recurse = True)
b.closeViewer()
ui.panes.current.placeOPs([cOp])

I’ve noticed if even run the following from default project (from /project1/):

cOp = op('/').create('sliderCOMP')
cOp.openViewer()
cOp.cook(force = True, recurse = True)
cOp.closeViewer()
ui.panes.current.placeOPs([cOp])

Result - sliderCOMP panel is not updating on mouse events unless cut+paste sliderCOMP.

Also if you run:

cOp = op('/').create('sliderCOMP')
ui.panes.current.placeOPs([cOp])

The original bug is still - loop dependency error and broken panel.

Best,
Alex

Hi @snaut ,
Thanks for the fix in 32260 - that helps a lot.
Here are leftovers that still brake panels:

#slider handle even not visible:
b = op('/').create('containerCOMP')
cOp = b.create('sliderCOMP')
b.cook(force = True, recurse = True)
ui.panes.current.placeOPs([cOp])

#slider handle visible but not moving
b = op('/').create('containerCOMP')
b.openViewer()
cOp = b.create('sliderCOMP')
b.cook(force = True, recurse = True)
b.closeViewer()
ui.panes.current.placeOPs([cOp])

#created annotate panel will be scaled weiredly 
#when draggin corners
c = parent().create('annotateCOMP')
ui.panes.current.placeOPs([c])

Cheers,
Alex
