        width = 'match_parent'
        Button:
            text = "Show snackbar"
            clicked :: sb.show = True
        TextView:

        TextView: tv:
            attr action = ""
            text << "Snackbar action: {}".format(self.action)
        Button:
            text = "Show snackbar with action"
            clicked :: sb2.show = True
    Snackbar: sb:
        duration = 4000
        text = "Cheers!"

    Snackbar: sb2:
        text = "Email deleted"
        action_text = "Undo"
        clicked :: app.show_toast("action clicked!")
        action :: tv.action = change['value']

Declaration¶

class enamlnative.widgets.snackbar.Snackbar(parent=None, **kwargs)[source]¶

Bases: enaml.widgets.toolkit_object.ToolkitObject

A toast is a view containing a quick little message for the user.

text¶

Text to display if this node has a child view this is ignored

action_text¶

Text to display in the action button

action_text_color¶

Color for the action text button

duration¶

Duration to display in ms or 0 for infinite

clicked¶

Alias for the action is clicked

action¶

When an action occurs such as swiped out, clicked, timed out, etc..

show¶

Show the snackbar for the given duration

proxy¶

A reference to the proxy object.

Android Implementation¶

class enamlnative.android.android_snackbar.AndroidSnackbar[source]¶

Bases: enamlnative.android.android_toolkit_object.AndroidToolkitObject, enamlnative.widgets.snackbar.ProxySnackbar

An Android implementation of an Enaml ProxySnackbar.

widget¶

A reference to the widget created by the proxy.

create_widget()[source]¶

Create the underlying widget.

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

init_widget()[source]¶

Our widget may not exist yet so we have to diverge from the normal way of doing initialization. See update_widget

on_widget_created(f: _asyncio.Future)[source]¶

Using Snackbar.make returns async so we have to initialize it later.

set_duration(duration)[source]¶

Android for whatever stupid reason doesn’t let you set the time it only allows 1-long or 0-short. So we have to repeatedly call show until the duration expires, hence this method does nothing see set_show.

No iOS implementation found.
