Editor to share with you how the PyQt in Python displays permanent messages, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

1. Add a persistent message to the status bar and use the QLabel object to save the message.

2. Add the label to the status bar through the call. AddPermanentWidget ().

This method permanently adds the given widget to the current status bar. The parent of the widget is set to the status bar.

.addPermanentWidget () takes the following two parameters:

Add the widget save widget object to the status bar. Some common widgets such as QLabel, QToolButton, QProgressBar, etc.

As the status bar grows and shrinks, stretch is used to calculate the appropriate size of the widget. It defaults to 0, which means that the widget will take up the least space.

Keep in mind that permanent widgets are not blocked or replaced by temporary messages. On the right side of the status bar, addPermanentWidget () locates the widget.

Example

Class Window (QMainWindow): # Snip... Def _ createStatusBar (self): self.statusbar = self.statusBar () # Adding a temporary message self.statusbar.showMessage ("Ready", 3000) # Adding a permanent message self.wcLabel = QLabel (f "{self.getWordCount ()} Words") self.statusbar.addPermanentWidget (self.wcLabel) these are all the contents of the article "how PyQt displays permanent messages in Python".
