I know the message can be set by opts in answer = questdlg(quest,dlgtitle,btn1,btn2,btn3,opts).
But is it possible to also change the font size of the buttons?
This page default-property-values gives some infomations. I checked the result of get(groot, 'factory'). There are factoryTextFontSize, factoryUibuttongroupFontSize, and factoryUicontrolFontSize.
But the command set(groot, 'factoryTextFontSize', 12) didn't work. Apparently get(groot, 'default) gives only 5 properties.
So how to deal with the default settings above?
