How to load and display ui created by qt designer in pyqt5 application?
Firstly, we should add ui python script files in our python project. Then, we can use them.
Here is an example:
# -*- coding: utf-8 -*- import sys import os from PyQt5.QtWidgets import QApplication, QMainWindow, QDialog from main_home import * if __name__ == '__main__': app = QApplication(sys.argv) # create a main window main = QMainWindow() main.setFixedSize(500, 320) main_win = Ui_PDFPageSpliter() main_win.setupUi(main) main.show() sys.exit(app.exec_())
In this example, Ui_PDFPageSpliter is a ui designed by qt designer. In order to display it in our application, we should set up a main window for it. Here is the core code:
main_win = Ui_PDFPageSpliter() main_win.setupUi(main)
Then we will display it as follows:
We also can use main_win to access ui elements in Ui_PDFPageSpliter. For exmaple:
In order to bind a click event for a button in Ui_PDFPageSpliter, we can do as follows:
