使用 *QFileDialog.SelectedFiles() 时报错, "接口转换: 接口 {} 为 []interface {}, 而非 []string"

**The Issue** I'm trying to get the directories selected when using QFileDialog but I keep getting the following error: panic: interface conversion: interface{} is []interface{}, not []string goroutine 20 [running]: GitHub.com/therecipe/qt/widgets.(*QFileDialog).SelectedFiles(0x0?)
