FontDialog.chooseFont

void chooseFont(gtk.window.Window parent =  null,  pango.font_description.FontDescription initialValue =  null,  gio.cancellable.Cancellable cancellable =  null,  gio.types.AsyncReadyCallback callback =  null)

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 [gtk.font_dialog.FontDialog.chooseFontFinish] to obtain the result.

If you want to let the user select font features as well, use [gtk.font_dialog.FontDialog.chooseFontAndFeatures] instead.

Parameters

`parent`	the parent [gtk.window.Window]
`initialValue`	the font to select initially
`cancellable`	a [gio.cancellable.Cancellable] to cancel the operation
`callback`	a callback to call when the operation is complete
