Description

As I alluded to in this comment, my colleague did not notice that the QDoubleSpinBox in the GroupPresetTableWidget could be edited. It'd be great to provide some visual clue (e.g. spin buttons) to indicate that it's editable, and not just a label.

that's a widget from superqt.
I'm a little bit conflicted on that one actually. Those are ugly and take up valuable space; and once you notice they're editable, you know it forever.
I can show you how to enable them via private methods (and we might want to add a public feature for that at superqt); I can see that someone might want it as an option; but I'm not immediately sure I want to make it the default appearance for everyone.

That's a fair point. There are a couple other things I can think of that could be helpful:

• Add a tooltip to the SpinBox that somehow implies editability
• Edit the border style of the SpinBox - that could be done within my UI, no change needed here, right?

I was thinking the same things. A tooltip on the combined slider-box widget could indicate which property it controls (as with the regular config groups), plus mention "click the number to enter a value".
Also, we should probably watch more people use it before concluding that we absolutely need to emphasize editability here.

yeah, i think this is something that the app-builder should do with style sheets. superqt does currently setStyleSheet on the slider label, but it shouldn't... and after pyapp-kit/superqt#254, you could do this yourself with a stylesheet:

from qtpy.QtWidgets import QApplication
from superqt import QLabeledSlider

app = QApplication([])
app.setStyleSheet(
    "SliderLabel { border: 2px solid black; background-color: yellow; }"
)
sld = QLabeledSlider()
sld.show()
app.exec()
