Is there any way to show our custom message in Qgis Status bar using python? Just like in arcgis IApplication.statusbar.message(0) = "Please wait..."

like that is there any option to show progressbar in Qgis like IApplication.progressbar.show()

StatusBar

There is iface.mainWindow().statusBar() which returns a QStatusBar

iface.mainWindow().statusBar().showMessage( u"Hello World" )

enter image description here

MessageBar

Starting from QGIS 2.0 there is also QgsMessageBar which is able to display unobtrusive messages 

iface.messageBar().pushInfo(u'My Plugin says', u'Hey there')

enter image description here

Advanced

The message bar can also show any QWidget (like a QProgressBar) with a close button and a timeout (5 seconds in the example).

from PyQt4.QtGui import QProgressBar
from qgis.gui import QgsMessageBar
msgBar = iface.messageBar()

pb = QProgressBar( msgBar )
msgBar.pushWidget( pb, QgsMessageBar.INFO, 5 )

msg = msgBar.createMessage( u'Hello World' )
msgBar.pushWidget( msg, QgsMessageBar.WARNING, 5 )

enter image description here

More info about QgsMessageBar can be found in this answer by NathanW How to address the new "Task-Completed" QgsMessageBar in Python? Thanks for pointing out Curlew

Legacy

In the python console for QGIS < 1.9 it would be:

qgis.utils.iface.mainWindow().statusBar().showMessage( u"Hello World" )

  • Thanks a lot Matthias..is there any option for progressbar? – venkat Apr 22 '13 at 11:33
  • In the QgsMessageBar you're able to display any kind of widget. I would not know that this is possible in the status bar. – Matthias Kuhn Apr 22 '13 at 11:36
  • I am very new to qgis and python.. could you please give me example for QgsMessageBar? and what is the meaning of using 'u' prefix in "Hello world" – venkat Apr 22 '13 at 11:40
  • The u prefix is for unicode strings. It will also work without this.

    For the QgsMessageBar you have to get the current development version of QGIS or wait for the release of 2.0.
