[pyqt5]pyqt5设置窗口背景图片后上面所有图片都会变成和背景图片一样

article 2024/9/26 1:15:10

pyqt5的控件所有都是集成widget，窗体设置背景图片后控件背景也会跟着改变，此时有2个办法。第一个办法显然我们可以换成其他方式设置窗口背景图片，而不是使用styleSheet样式表，网上有很多其他方法。还有个办法就是仍然用styleSheet样式表，但是我们设计designer时候暂时不管拖放控件，然后转成py文件时候重新设置控件styleSheet。下面是我设计窗体时候出现情况

上面拖了一个控件pushButton就这样了。转成py文件后改下代码如下：

from PyQt5 import QtCore, QtGui, QtWidgets
import image_rc

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(844, 663)
        MainWindow.setStyleSheet("border-image: url(:/1/example.jpg);")
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.pushButton = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton.setGeometry(QtCore.QRect(290, 300, 401, 201))
        self.pushButton.setObjectName("pushButton")
        self.pushButton.setStyleSheet('border-image: url(test.png);')
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 844, 30))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.pushButton.setText(_translate("MainWindow", "PushButton"))
import image_rc


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())
