PyQt5直接加载UI文件，而不是将其转化为.py文件。

PySide2直接加载UI文件

通过Qt Creator新建Qt for Python项目

自动生成直接加载UI文件代码：

# This Python file uses the following encoding: utf-8
import os
from pathlib import Path
import sys

from PySide2.QtWidgets import QApplication, QWidget
from PySide2.QtCore import QFile
from PySide2.QtUiTools import QUiLoader


class UITest(QWidget):
    def __init__(self):
        super(UITest, self).__init__()
        self.load_ui()

    def load_ui(self):
        loader = QUiLoader()
        path = os.fspath(Path(__file__).resolve().parent / "form.ui")
        ui_file = QFile(path)
        ui_file.open(QFile.ReadOnly)
        loader.load(ui_file, self)
        ui_file.close()


if __name__ == "__main__":
    app = QApplication([])
    widget = UITest()
    widget.show()
    sys.exit(app.exec_())

PyQt5直接加载UI文件

仿造上述代码

```python

This Python file uses the following encoding: utf-8

import sys

from PyQt5.QtWidgets import QApplication, QWidget
from PyQt5.uic import loadUi

class UITest(QWidget):
def init(self, parent=None):
super().init()
loadUi(‘form.ui’, self)
self.setFixedSize(600, 400)
self.pushButton.clicked.connect(self.onButtonClicked)#可直接self.pushButton,该QPushButton变量在UI中定义

def onButtonClicked(self):
    x = random.randint(self.pushButton.width(), self.width() - self.pushButton.width())
    y = random.randint(self.pushButton.height(), self.height() - self.pushButton.height())
    self.pushButton.move(x, y)

if name == “main“:
app = QApplication([])
widget = UITest()
widget.show()
sys.exit(app.exec_())
