在Qt For Python中，布局相关的类位于QtWidgets模块中，通过下面的代码，我们可以创建一个内为水平布局的主窗口： class LayoutApp(QtWidgets.QMainWindow...('按钮一') button_2 = QtWidgets.QPushButton('按钮二') button_3 = QtWidgets.QPushButton('按钮三...('按钮一') button_2 = QtWidgets.QPushButton('按钮二') button_3 = QtWidgets.QPushButton('按钮三...('按钮一') button_2 = QtWidgets.QPushButton('按钮二') button_3 = QtWidgets.QPushButton('按钮三...我们来看具体的例子： from PySide2 import QtWidgets import sys class LayoutApp(QtWidgets.QMainWindow): '''

下面两行是PyQt 截屏的关键代码： screen= QtWidgets.QApplication.primaryScreen()#PyQt5 screen.grabWindow(QtWidgets.QApplication.desktop.../usr/bin/env python from PyQt5 import QtCore, QtWidgets,QtGui class Screenshot(QtWidgets.QWidget):...__init__() self.screenshotLabel = QtWidgets.QLabel() self.screenshotLabel.setSizePolicy...(QtWidgets.QSizePolicy.Expanding, QtWidgets.QSizePolicy.Expanding) self.screenshotLabel.setAlignment...= 0: QtWidgets.qApp.beep() # Garbage collect any existing image first.
我们将其添加到上面创建的主窗口中，代码如下所示： # coding:utf-8 from PyQt5 import QtWidgets import sys class ButtonApp(QtWidgets.QMainWindow...) self.btn_1 = QtWidgets.QPushButton("按钮一") self.btn_2 = QtWidgets.QPushButton()...) self.btn_1 = QtWidgets.QPushButton("按钮一") self.btn_2 = QtWidgets.QPushButton()..._2 = QtWidgets.QPushButton() self.btn_2.setText("按钮二") self.btn_3 = QtWidgets.QPushButton..._2 = QtWidgets.QPushButton() self.btn_2.setText("按钮二") self.btn_3 = QtWidgets.QPushButton

桌面客户端的实现 首先，创建一个桌面主窗口和一个登录窗口： class LoginWindow(QtWidgets.QMainWindow): def __init__(self):...) self.username_input = QtWidgets.QLineEdit() # 用户名输入框 self.pwd_input = QtWidgets.QLineEdit...() # 密码输入框 self.pwd_input.setEchoMode(QtWidgets.QLineEdit.Password) # 密码输入框设置文本显示*号...下面，我们再创建一个主窗口，当登录成功之后，程序自动切换到这个主窗口上： class MainWindow(QtWidgets.QMainWindow): def __init__(self):...error_box.setIcon(QtWidgets.QMessageBox.Warning) error_box.setText("请输入用户名或密码")
