Pyqt5 and qt-designer

Pyqt5 and qt-designer

We installed the python3-pyqt5 package in Ubuntu can use pyqt5 programming, but only use pure code to write the form, very troublesome. We will use qt-designer to design the form.

Install PyQt 5 in Ubuntu

We can install the qt4-designer package through the new, or through the shell command apt-get install. The interface is as follows:

After the software design form is complete, it is saved as a ui file. We need to convert it to a py file. We need to use the command pyuic5 or pyuic4. we cannot use this command because the corresponding package is not installed.

This command is in the pyqt4-dev-tools package, we can install it through the new or shell command.

Conversion FILE command:

# Generate a. pypyuic4-o a. py a. ui

Let's take a look at the newly generated a. py:

A class Ui_Form is automatically generated, and the class has a method setupUi ()

Create a python file and import a. py

Import sys from PyQt5.QtWidgets import QApplication, QWidget # import the corresponding package from a import * if _ name _ = '_ main _': app = QApplication () w = QWidget () ui = Ui_Form () ui. setupUi (w) w. show () sys. exit (app.exe c _())
