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_())
