Dialog
Dialog is like a window, but it has buttons that are automatically laid out.
A Dialog should have one main element as child, that isn’t a button.
The dialog can have any number of StandardButton
widgets or other buttons
with the dialog-button-role
property.
The buttons will be placed in an order that depends on the target platform at run-time.
The kind
property of the StandardButton
s and the dialog-button-role
properties need to be set to a constant value, it can’t be an arbitrary variable expression.
There can’t be several StandardButton
s of the same kind.
A callback <kind>_clicked
is automatically added for each StandardButton
which doesn’t have an explicit
callback handler, so it can be handled from the native code: For example if there is a button of kind cancel
,
a cancel_clicked
callback will be added.
Each of these automatically-generated callbacks is an alias for the clicked
callback of the associated StandardButton
.
