Subject: Fixed min and max label values not being swapped when using wxSL_INVERSE in a horizon... 
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/cac008ad62d1e4f10f22e25f599990e3db69b355?ds=inline

Fixed min and max label values not being swapped when using wxSL_INVERSE in a horizontal MSW slider.

Changed wxSlider::GetLabelsSize to let the widthMin and widthMax values contain the width of what the minimum (always on the left/top) and maximum (always on the right/bottom) _label_ will contain. This is not the same as the minimum and maximum _value_ in case of using wxSL_INVERSE.

Also don't swap the position of the min/max labels in a horizontal slider with wxSL_INVERSE (just how the labels already stay in place in a vertical slider, regardless of wxSL_INVERSE usage), nor their width.

Regression since r65941.

Fixes #13416.
