python3.x+pyqt5实现主窗口状态栏里(嵌入)显示进度条功能
1、代码1:
(1)进度条等显示在主窗口状态栏的右端,代码如下:
from PyQt5.QtWidgets import QMainWindow, QProgressBar, QApplication, QLabel import sys class SampleBar(QMainWindow): """Main Application""" def __init__(self, parent = None): print('Starting the main Application') super(SampleBar, self).__init__(parent) self.initUI() def initUI(self): # Pre Params: self.setMinimumSize(800, 600) # File Menus & Status Bar: self.statusBar().showMessage('准备中...') self.progressBar = QProgressBar() self.label = QLabel() self.label2 = QLabel() self.label.setText("正在计算: ") self.label2.setText("正在计算: ") self.statusBar().addPermanentWidget(self.label) self.statusBar().addPermanentWidget(self.label2) self.statusBar().addPermanentWidget(self.progressBar) # self.statusBar().addWidget(self.progressBar) # This is simply to show the bar self.progressBar.setGeometry(0, 0, 100, 5) self.progressBar.setRange(0, 500) # 设置进度条的范围 self.progressBar.setValue(100) if __name__ == '__main__': app = QApplication(sys.argv) main2 = SampleBar() main2.show() sys.exit(app.exec_())

2、代码2:
(1)进度条等显示在主窗口状态栏的左端,代码如下:
from PyQt5.QtWidgets import QMainWindow, QProgressBar, QApplication, QLabel, \ QStatusBar, QPushButton import sys class SampleBar(QMainWindow): """Main Application""" def __init__(self, parent = None): # print('Starting the main Application') super(SampleBar, self).__init__(parent) self.initUI() def initUI(self): # Pre Params: self.setMinimumSize(800, 600) # File Menus & Status Bar: self.statusBar = QStatusBar() self.statusBar.setStyleSheet('QStatusBar::item {border: none;}') self.setStatusBar(self.statusBar) self.statusBar.showMessage('准备') self.progressBar = QProgressBar() self.pushbutton = QPushButton("点这里") self.label = QLabel() self.label2 = QLabel() self.label.setText("开始计算 ") self.label2.setText("正在计算: ") # self.statusBar.addWidget(self.label, 0) self.statusBar.addPermanentWidget(self.label, stretch=2) self.statusBar.addPermanentWidget(self.label2, stretch=0) self.statusBar.addPermanentWidget(self.progressBar, stretch=4) # self.statusBar().addWidget(self.progressBar) # This is simply to show the bar # self.progressBar.setGeometry(0, 0, 100, 5) self.progressBar.setRange(0, 500) # 设置进度条的范围 self.progressBar.setValue(20) if __name__ == '__main__': app = QApplication(sys.argv) main2 = SampleBar() main2.show() sys.exit(app.exec_())
