Inherits:
Item
Imports:
org.kde.plasma.core
QtQuick 1.0
Description:
An item delegate for the primitive ListView component. It's intended to make all listview look coherent
Properties:
* bool checked:
If true makes the list item look as checked or pressed. It has to be set from the code, it won't change by itself.
* bool sectionDelegate:
If true the item will be a delegate for a section, so will look like a "title" for the otems under it.
* bool enabled:
Holds if the item emits signals related to mouse interaction.
The default value is false.
Signals:
* clicked():
This handler is called when there is a click.
This is disabled by default, use enable property to activate it.
* pressAndHold():
The user pressed the item with the mouse and didn't release it for a certain amount of time.
This is disabled by default, use enable property to activate it.
