ComboBox drop down size with alternate fonts

[rubixcuber]

Normally the drop down portion of the combo box is sized to fit the choices, but when changing the font it seems to still use the size for the base font as shown below.



Is there any way to make this work without changing the engine? Or is there something I'm missing?

I'll have to check, but that sounds like a bug. I try to find some time next week to look into it. Thanks for the report.

edit: Did you try to call setMaxSelectionRows after changing the font? That could be a workaround.

[rubixcuber]

Looks like calling setMaxSelectionRows will change the size, but still based on the the base font and will not make it any larger than the number of entries so it still ends up cut off with a larger font.

OK, took me a while until I got this. This only happened when the font changed while that list was open. It's fixed in svn trunk r5009.
