Consider adding QSpinBox API to QLabeledSlider

[gselzer]

Consider a slider wrapping a percentage value. If you want to add % as a suffix on the label, you have to access the private _label field.

Of course, for something like a QLabeledDoubleRangeSlider, there are 4 different labels that then have to be edited.

I think it'd be great if the QLabeledSlider had the API for this.

Happy to file a PR if people like the idea.

Definitely 👍

Rather than passing through all the methods though, maybe we follow the same thing that complex qt widgets do (like QComboBox.lineedit https://doc.qt.io/qt-6/qcombobox.html#lineEdit) and add a method that returns the full widget like .spinBox() and/or .label()?

Not sure if setters would be appropriate, but maybe those too

Yeah, that was my first thought, but like I mentioned with QLabeledDoubleRangeSlider, there are then two labels (and arguably we'd also want e.g. the suffix on the handles, too) - I think the extensibility required warrants passthrough...

Ahh I see. Ok so the pass through would update all of them?

In any case, I’m supportive of the general goal of making that publicly accessible and open to whatever PR you come up with!
