• correct spelling of method name so Qt will use it!

This typo appears to have come in via b7d1d59 in 2007 and been carried forward through all of the Qt refactors

This typo appears to have come in via b7d1d59 in 2007 and been carried forward through all of the Qt refactors

I can't even tell what the effect is, given that the intended minimum size of width=10, height=10 appears to be too small (to me) anyway.

We had a number of issues where we would end up with 0 pixel sized widgets that lead to crashes in the rasterizer. I suspect that the intent of the minimumSizeHint is to make sure Qt never squashes the widget all they way to 0 so the figure is always technically render able (if useless).

Given it has never worked, and we have other fixes for the issues it being missing caused, just removing it is also an option. However, I still lean towards "fix it".

Fixed by #28732.
