Pyqt5 rapid development and practice 3.6 packaging resource files

PyQt5 Rapid development and actual combat

3. The first 3 Chapter Qt Designer Use

3.6 Package resource files

Use PyQt5 There are two main ways for the generated application to reference image resources ：

• Convert the resource file to Python file , Then the reference Python file
• Reference external image resources through relative paths in the program

3.6.1 Use Qt Designer Load resource file

New resource file apprcc.qrc

Create a new simple form

Resource editing

Add resources

apprcc.qrc The file automatically adds code

3.6.2 Use resource files in forms

Add one label label , change pixmap attribute

ui turn py

Call module CallMainWin02.py

Here we have to put .qrc The document is also changed to py file

And then call

import sys
from PyQt5.QtWidgets import QApplication,QMainWindow
from MainWin02 import Ui_Form

class MyMainWindow(QMainWindow,Ui_Form):
    def __init__(self,parent = None):
        super(MyMainWindow,self).__init__(parent)
        self.setupUi(self)

if __name__ == '__main__':
    
    from pyqt5_plugins.examples.exampleqmlitem import QtCore
    QtCore.QCoreApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling)
    
    app = QApplication(sys.argv)
    myWin = MyMainWindow()
    myWin.show()
    sys.exit(app.exec_())

function

3.6.3 Convert resource files

3.6.4 Import .py Resource file

It has been operated in advance here .

Finally, everything in the script is normal , You can see the imported image resources in the window .
