Examples

>>> enamldef AlertDialog(Dialog): dialog:
      attr result: lambda text: None
      TextView:
        text = "Are you sure you want to delete?"
      Button:
        text = "Yes"
        clicked ::
          dialog.show = False
          dialog.result(self.text)
      Button:
        text = "No"
        clicked ::
          dialog.show = False
          dialog.result(self.text)
    def on_result(value):
      print("User clicked: {}".format(value))
    AlertDialog(result=on_result).popup()

Notes

This does NOT block. Callbacks should be used to handle click events or the show state should be observed to know when it is closed.

Android Implementation¶

class enamlnative.android.android_dialog.AndroidDialog[source]¶

Bases: enamlnative.android.android_toolkit_object.AndroidToolkitObject, enamlnative.widgets.dialog.ProxyDialog

An Android implementation of an Enaml ProxyDialog.

dialog¶

A reference to the widget created by the proxy.

create_widget()[source]¶

Create the underlying widget.

A dialog is not a subclass of view, hence we don’t set name as widget or children will try to use it as their parent.

init_widget()[source]¶

Set the listeners

init_layout()[source]¶

If a view is given show it

child_added(child)[source]¶

Overwrite the content view

destroy()[source]¶

A reimplemented destructor that cancels the dialog before destroying.

on_key(dialog, key, event)[source]¶

Trigger the key event

Parameters

• view (int) – The ID of the view that sent this event

• key (int) – The code of the key that was pressed

• data (bytes) – The msgpack encoded key event
