gtk:font-dialog-choose-font (dialog parent desc cancellable func)

dialog -- a gtk:font-dialog object
parent -- a parent gtk:window widget
desc -- a pango:font-description object
cancellable -- a g:cancellable object to cancel the operation
func -- a g:async-ready-callback callback function to call when the operation is complete

This function initiates a font selection operation by presenting a dialog to the user for selecting a font. The callback will be called when the dialog is dismissed. It should call the gtk:font-dialog-choose-font-finish function to obtain the result.

If you want to let the user select font features as well, use the gtk:font-dialog-choose-font-and-features function instead.
