How to add plugin icon to status bar using PyQGIS?

Question

I would like add my plugin icon to the status bar at the bottom of the screen. How would I do that? (QGIS API documentation on statusBar() seems to be leading to the QT docs and that site is down right now)

Answer 1

It's quite simple.

Create QToolButton class instance by calling (might be in init() section):

self.button = QToolButton()

Then in initGui() method put this lines:

#set default action for this button (I've chosen my second action, so that's why I put 1st index)
self.button.setDefaultAction(self.actions[1])

#add the button to statusbar
self.iface.mainWindow().statusBar().addPermanentWidget(self.button)

Last thing, that might be useful is adding this line to unload() method:

self.iface.mainWindow().statusBar().removeWidget(self.button)

It will prevent button to get multiple, e. g. after you reload a plugin.
