Widget description
|
|
------------------
|
|
|
|
A Multibuttonentry is a widget to allow a user enter text and manage
|
|
it as a number of buttons. Each text button is inserted by pressing the
|
|
"return" key. If there is no space in the current row, a new button is
|
|
added to the next row. When a text button is pressed, it will become
|
|
focused. Backspace removes the focus. When the Multibuttonentry loses
|
|
focus items longer than one line are shrunk to one line.
|
|
|
|
Typical use case of multibuttonentry is, composing emails/messages to a
|
|
group of addresses, each of which is an item that can be clicked for
|
|
further actions.
|
|
|
|
This widget emits the following signals, besides the ones sent from
|
|
:py:class:`LayoutClass<efl.elementary.layout_class.LayoutClass>`:
|
|
|
|
- ``item,selected`` - this is called when an item is selected by
|
|
api, user interaction, and etc. this is also called when a
|
|
user press back space while cursor is on the first field of
|
|
entry.
|
|
- ``item,added`` - when a new multi-button entry item is added.
|
|
- ``item,deleted`` - when a multi-button entry item is deleted.
|
|
- ``item,clicked`` - this is called when an item is clicked by user
|
|
interaction. Both "item,selected" and "item,clicked" are needed.
|
|
- ``clicked`` - when multi-button entry is clicked.
|
|
- ``focused`` - when multi-button entry is focused.
|
|
- ``unfocused`` - when multi-button entry is unfocused.
|
|
- ``expanded`` - when multi-button entry is expanded.
|
|
- ``contracted`` - when multi-button entry is contracted.
|
|
- ``expand,state,changed`` - when shrink mode state of
|
|
multi-button entry is changed.
|
|
|
|
Default text parts of the multibuttonentry widget that you can use for are:
|
|
- "default" - A label of the multibuttonentry
|
|
|
|
Default text parts of the multibuttonentry items that you can use for are:
|
|
- "default" - A label of the multibuttonentry item
