バージョン 1.4.0 で追加.

The ModalView widget is used to create modal views. By default, the view will cover the whole “parent” window.

Remember that the default size of a Widget is size_hint=(1, 1). If you don’t want your view to be fullscreen, either use size hints with values lower than 1 (for instance size_hint=(.8, .8)) or deactivate the size_hint and use fixed size attributes.


Example of a simple 400x400 Hello world view:

view = ModalView(size_hint=(None, None), size=(400, 400))
view.add_widget(Label(text='Hello world'))

By default, any click outside the view will dismiss it. If you don’t want that, you can set ModalView.auto_dismiss to False:

view = ModalView(auto_dismiss=False)
view.add_widget(Label(text='Hello world'))

To manually dismiss/close the view, use the ModalView.dismiss() method of the ModalView instance:


Both ModalView.open() and ModalView.dismiss() are bindable. That means you can directly bind the function to an action, e.g. to a button’s on_press

# create content and add it to the view
content = Button(text='Close me!')
view = ModalView(auto_dismiss=False)

# bind the on_press event of the button to the dismiss function

# open the view

ModalView Events

There are two events available: on_open which is raised when the view is opening, and on_dismiss which is raised when the view is closed. For on_dismiss, you can prevent the view from closing by explictly returning True from your callback.

def my_callback(instance):
    print('ModalView', instance, 'is being dismissed, but is prevented!')
    return True
view = ModalView()
view.add_widget(Label(text='Hello world'))

バージョン 1.5.0 で変更: The ModalView can be closed by hitting the escape key on the keyboard if the ModalView.auto_dismiss property is True (the default).

dismiss(*largs, **kwargs)[ソース]

Close the view if it is open. If you really want to close the view, whatever the on_dismiss event returns, you can use the force argument:

view = ModalView()

When the view is dismissed, it will be faded out before being removed from the parent. If you don’t want animation, use:


Show the view window from the attach_to widget. If set, it will attach to the nearest window. If the widget is not attached to any window, the view will attach to the global Window.
