## Open file dialog ## Adding a file chooser
> :warning: This method is deprecaded, see next section!
Let's make that open button actually show an open file dialog
```python
self.open_dialog = Gtk.FileChooserNative.new(title="Choose a file",
parent=self, action=Gtk.FileChooserAction.OPEN)
self.open_dialog.connect("response", self.open_response)
self.open_button.connect("clicked", self.show_open_dialog)
def show_open_dialog(self, button):
self.open_dialog.show()
def open_response(self, dialog, response):
if response == Gtk.ResponseType.ACCEPT:
file = dialog.get_file()
filename = file.get_path()
print(filename) # Here you could handle opening or saving the file
```
The action type can also be **SAVE** and **SELECT_FOLDER**
If you wanted to restrict the file types shown, you could add a filter. For example:
```python
f = Gtk.FileFilter()
f.set_name("Image files")
f.add_mime_type("image/jpeg")
f.add_mime_type("image/png")
self.open_dialog.add_filter(f)
```
## Adding a file chooser (updated)
Here we use [***Gtk.FileDialog***](https://docs.gtk.org/gtk4/class.FileDialog.html) to present an open file dialog to the user. Here we use [***Gtk.FileDialog***](https://docs.gtk.org/gtk4/class.FileDialog.html) to present an open file dialog to the user.
