每当我点击APP GUI中的任何地方时，打印困难（“ok”）

问题描述 投票：1回答：1

我使用QT Designer设计GUI，然后通过以下方式将.ui文件导入我的python代码：

ui_file = QFile(ui_file)
        ui_file.open(QFile.ReadOnly)
        loader = QUiLoader()
        self.window = loader.load(ui_file)
        ui_file.close()

当一切运行python代码时，GUI确实出现并且功能正常但是我在实现功能方面遇到了困难：“每当我点击GUI上的任何一点时，我都要打印（”确定“）。这是我的代码：

import sys
from PySide2.QtUiTools import QUiLoader
from PySide2.QtWidgets import QApplication, QComboBox, QCheckBox, QLabel, QPushButton, QFrame, QAction, QDesktopWidget, QTabWidget, QMainWindow, QWidget
from PySide2.QtCore import QFile, QObject,Qt, QPoint
from PySide2 import QtCore, QtGui

class MyApp(QObject):
    def __init__(self, ui_file, parent=None):
        super(MyApp, self).__init__(parent)
        ui_file = QFile(ui_file)
        ui_file.open(QFile.ReadOnly)
        loader = QUiLoader()
        self.window = loader.load(ui_file)
        ui_file.close()
        self.window.setWindowFlags(QtCore.Qt.FramelessWindowHint)
        self.window.show()

    def mousePressEvent(self, event):    
        print("ok")

if __name__ == '__main__':
    app = QApplication(sys.argv)
    form = MyApp('GUI.ui')
    sys.exit(app.exec_())

这是UI文件：PS。制作一个新的GUI.ui文件并用记事本编辑它并添加以下代码，你将获得我的GUI.ui文件：

MyApp不是小部件，因此mousePressEvent不存在，窗口越少。所以在这些情况下你应该使用一个事件过滤器：

import sys
from PySide2 import QtCore, QtWidgets, QtUiTools

class MyApp(QtCore.QObject):
    def __init__(self, ui_file, parent=None):
        super(MyApp, self).__init__(parent)
        ui_file = QtCore.QFile(ui_file)
        if ui_file.open(QtCore.QFile.ReadOnly):
            loader = QtUiTools.QUiLoader()
            self.window = loader.load(ui_file)
            self.window.installEventFilter(self)
            self.window.setWindowFlags(QtCore.Qt.FramelessWindowHint)
            self.window.show()

    def eventFilter(self, obj, event):
        if obj is self.window:
            if event.type() == QtCore.QEvent.MouseButtonPress:
                print("ok")
        return super(MyApp, self).eventFilter(obj, event)

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    form = MyApp('GUI.ui')
    sys.exit(app.exec_())
