Meego Panel Reference Manual | |
|---|
Meego Panel is an application that inserts a button into the Meego Shell Toolbar, optionally associated with a drop-down panel shown when the users clicks on the button. The Panel controls the styling of the Toolbar button (provided by the Shell), and the associated tooltip. The drop down panel itself is a window provided by the Panel application.
Communication between the Panel and the Toolbar is done over D-Bus: the Panel application is required to implement the org.meego.UX.Shell.Panelinterface through which the Toolbar manipulates the Panel; libmeego-panel encapsulates implementation of this interface in the MplPanelClient class, with subclasses for specific panel use-cases and toolkit choice MplPanelClutter, MplPanelGtk, MplPanelWindowless. These classes mean that a panel application can be created with minimal development overhead.
The position of a panel on the Toolbar is determined by a list stored
in GConf under the key /desktop/meego/toolbar/panels/order
; this can be altered by the user using the Toolbar settings
applet.
In general, panels are lazy-loaded by the Toolbar first time the user clicks the associated button. In order to facilitate this, each Panel must provide a desktop file containing the information necessary to construct the Toolbar button and to start the Panel.
