Creates a new builder-pattern struct instance to construct FontButton objects.

This method returns an instance of FontButtonBuilder which can be used to create FontButton objects.

Gets whether the dialog is modal.

Returns

true if the dialog is modal

Retrieves the title of the font chooser dialog.

Returns

an internal copy of the title string which must not be freed.

Returns whether the selected font is used in the label.
