Statusbar Interface

The StatusbarInterface can be used by plugins to send messages to OpenFlippers statusbar. The statusbar is located below the GL viewer.

Messages can be controlled via StatusbarInterface::setStatus(),StatusbarInterface::clearStatusMessage()

Additionally it is possible to add small widgets to it ( StatusbarInterface::addWidgetToStatusbar).

A small icon can be controlled to indicate OpenFlippers status via StatusbarInterface::setStatus().

To use the StatusbarInterface:

- include StatusbarInterface.hh in your plugins header file
- derive your plugin from the class StatusbarInterface
- add Q_INTERFACES(StatusbarInterface) to your plugin class
- And add the signals or slots you want to use to your plugin class (You don't need to implement all of them)

The following code shows a simple example to send a message to the statusbar.

void ExamplePlugin::function()
{
...
// Print the text "Your Status Message" for 4 seconds in the statusBar
emit showStatusMessage( tr("Your Status Message"), 4000 );
...
}

The following code shows a simple example to add a widget to the statusbar. Usually you should implement the BaseInterface::pluginsInitialized() function from BaseInterface. In this function you can setup your widget for the status bar.

void ExamplePlugin::pluginsInitialized()
{
// Create the widget
QWidget* infoBar = new QWidget();
// Setup buttons or anything else in your widget
...
// Add the new widget to the statusBar
emit addWidgetToStatusbar(infoBar);
}
