Summary: in this tutorial, you’ll learn how to use the PyQt QStatusBar<\/code> class to create status bar widgets.<\/p>\n\n\n\n

Introduction to the PyQt QStatusBar class #<\/a><\/h2>\n\n\n\n

The QStatusBar<\/code> class allows you to create a status bar widget. The status bar widget is useful for presenting status information.<\/p>\n\n\n\n

Typically, you’ll use the statusBar()<\/code> method of the QMainWindow<\/code> object to create a status bar for the main window:<\/p>\n\n\n

self.status_bar = self.statusBar()<\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
The statusBar()<\/code> method returns the status bar of the main window. If the status bar doesn’t exist, the function creates and returns an empty status bar.<\/p>\n\n\n\n
So if you assign the status bar to the self.status_bar<\/code> variable, you can use the variable later in other methods of the class.<\/p>\n\n\n\n
Or you can directly call the self.statusBar<\/code>()<\/code> method to get the QStatusBar<\/code> object and call its method.<\/p>\n\n\n\n
To show a message on the status bar, you use the showMessage()<\/code> method of the QStatusBar<\/code> object.<\/p>\n\n\n
showMessage(text,timeout=0<\/span>)<\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
By default, the showMessage()<\/code><\/code> message will display the text until you call the clearMessage()<\/code> or the showMessage()<\/code><\/code> method again.<\/p>\n\n\n\n
The timeout specifies the number of milliseconds the message will display. The timeout defaults to zero which displays the text permanently.<\/p>\n\n\n\n
Each status on the status has one of the following categories:<\/p>\n\n\n\n
