NewQFileDialog2 SelectedFiles() method panics #1188
Description
I'm on MacOS Big Sur. Everything works great until the OK button is pressed and I try to print the file path. My example looks very similar to what you have in your example.
// OpenPDFInput opens the PDF that needs to be inverted.
func (gui *GUI) OpenPDFInput() {
fileDialog := widgets.NewQFileDialog2(gui.Window, "Open PDF", gui.UserInfo.HomeDir, "")
fileDialog.SetAcceptMode(widgets.QFileDialog__AcceptOpen)
fileDialog.SetFileMode(widgets.QFileDialog__ExistingFile)
fileDialog.SetMimeTypeFilters([]string{"application/pdf"})
if fileDialog.Exec() == int(widgets.QDialog__Accepted) {
fmt.Printf("%v\n", fileDialog.SelectedFiles()[0])
}
}
As soon as fileDialog.SelectedFiles() runs, I get a panic. I am not sure why though. I may possibly be doing something wrong, but my example is very similar to yours (and everything else in my program works fine). Here is the error:
panic: interface conversion: interface {} is []interface {}, not []string
