My driver IBMTTS launch a file dialog from the configuration settings,
it shows a category in the NVDA settings dialog.
You can use that add-on as reference.

But I have a personal add-on that launch a file dialog from a script,
I did not publish the add-on because is just for personal purposes,
but see the code I used here. This is the function called by the
script:

def setFile(self):	
		d = wx.FileDialog(gui.mainFrame, message= _("Select the text to show
in the document loader"),
			# Translators: the label for the text document extension (txt) file type
			wildcard=(_("text files (*.{ext})")+"|*.{ext}").format(ext="txt"))
		def callback(result):
			if result == wx.ID_OK:
				text = open(d.GetPath(),encoding="utf-8").read()
				self.document = SimpleTextResult(text)
				self.documentUi = CustomTextUi(result = self.document)
				self.documentUi.setFocus()
		gui.runScriptModalDialog(d, callback)

Hello.


Does anyone know why I can't use a wx.FileDialog in a globalPlugin
script? NVDA crashes. However, elsewhere, for example calling it from
the NVDA menu it works perfectly.


Thanks
