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]:

I don't even know if this library is recieving maintenance anymore, but if it is I'd like to know if it's an issue with my code or the library itself

The code

	widget := widgets.NewQWidget(nil, 0)
	widget.SetLayout(widgets.NewQHBoxLayout())
	mw.MainWin.SetCentralWidget(widget)

	input := widgets.NewQLineEdit(nil)
	input.SetPlaceholderText("Insert path...")
	widget.Layout().AddWidget(input)

	fileDialog := widgets.NewQFileDialog2(nil, "Select file", ".", "")
	fileDialog.SetFileMode(widgets.QFileDialog__Directory)

	button := widgets.NewQPushButton2("Search folders", nil)
	button.SetMaximumSize2(50, 50)
	button.ConnectClicked(func(bool) {
		widgets.QMessageBox_Information(nil, "OK", input.Text(), widgets.QMessageBox__Ok, widgets.QMessageBox__Ok)
		if fileDialog.Exec() == 1 {
			files := fileDialog.SelectedFiles()
			fmt.Printf("V: %v", files)
		}
	})
	widget.Layout().AddWidget(button)

The error always happens at when .SelectedFiles() is called.
