1. move方法
import sysfrom PyQt4 import QtGuiclass Example(QtGui.QWidget): def __init__(self): super(Example, self).__init__() self.initUI() def initUI(self): lbl1 = QtGui.QLabel('ZetCode', self) lbl1.move(15, 10) lbl2 = QtGui.QLabel('tutorials', self) lbl2.move(35, 40) lbl3 = QtGui.QLabel('for programmers', self) lbl3.move(55, 70) self.setGeometry(300, 300, 250, 150) self.setWindowTitle('Absolute') self.show()
使用move方法移动创建对象的位置。可以看到在使用Qlabel方法创建了一个label之后，使用期其move方法讲这个label移动到了特定的位置
2. 窗口的layout方法
import sysfrom PyQt4 import QtGuiclass Example(QtGui.QWidget): def __init__(self): super(Example, self).__init__() self.initUI() def initUI(self): okButton = QtGui.QPushButton("OK") cancelButton = QtGui.QPushButton("Cancel") hbox = QtGui.QHBoxLayout() hbox.addStretch(1) hbox.addWidget(okButton) hbox.addWidget(cancelButton) vbox = QtGui.QVBoxLayout() vbox.addStretch(1) vbox.addLayout(hbox) self.setLayout(vbox) self.setGeometry(300, 300, 300, 150) self.setWindowTitle('Buttons') self.show() def main(): app = QtGui.QApplication(sys.argv) ex = Example() sys.exit(app.exec_())if __name__ == '__main__': main() 使用addStretch方法来表示按钮在窗口上的位置 QHBoxLayout 和 QVBoxLayout 分别代表横向和纵向的位置。
3. 通过坐标直接放置窗口
import sysfrom PyQt4 import QtGuiclass Example(QtGui.QWidget): def __init__(self): super(Example, self).__init__() self.initUI() def initUI(self): grid = QtGui.QGridLayout() self.setLayout(grid) names = ['Cls', 'Bck', '', 'Close', '7', '8', '9', '/', '4', '5', '6', '*', '1', '2', '3', '-', '0', '.', '=', '+'] positions = [(i,j) for i in range(5) for j in range(4)] for position, name in zip(positions, names): if name == '': continue button = QtGui.QPushButton(name) grid.addWidget(button, *position) self.move(300, 150) self.setWindowTitle('Calculator') self.show() def main(): app = QtGui.QApplication(sys.argv) ex = Example() sys.exit(app.exec_())if __name__ == '__main__': main() 使用QGridLayout的方法，直接通过坐标来定义Button的位置。注意（i,j）中数字的大小是用来表示先后顺序的，其本身并没有特殊意义。我们稍微修改一下代码：
import sysfrom PyQt4 import QtGuiclass Example(QtGui.QWidget): def __init__(self): super(Example, self).__init__() self.initUI() def initUI(self): grid = QtGui.QGridLayout() self.setLayout(grid) name_1 = 'Open' position_1 = (1,1) name_2 = 'Close' position_2 = (2,2) self.move(300, 150) self.setWindowTitle('Calculator') self.show() def main(): app = QtGui.QApplication(sys.argv) ex = Example() sys.exit(app.exec_())if __name__ == '__main__': main() import sysfrom PyQt4 import QtGuiclass Example(QtGui.QWidget): def __init__(self): super(Example, self).__init__() self.initUI() def initUI(self): grid = QtGui.QGridLayout() self.setLayout(grid) name_1 = 'Open' position_1 = (1,1) name_2 = 'Close' position_2 = (3,3) self.move(300, 150) self.setWindowTitle('Calculator') self.show() def main(): app = QtGui.QApplication(sys.argv) ex = Example() sys.exit(app.exec_())if __name__ == '__main__': main() 在运行之后我们得到了相同的窗口按钮布局，这说明，数字式排序用，而不是直接定位（太麻烦了。。。）
（关于Zip，新手可参见 http://www.cnblogs.com/BeginMan/archive/2013/03/14/2959447.html）
import sysfrom PyQt4 import QtGuiclass Example(QtGui.QWidget): def __init__(self): super(Example, self).__init__() self.initUI() def initUI(self): title = QtGui.QLabel('Title') author = QtGui.QLabel('Author') review = QtGui.QLabel('Review') titleEdit = QtGui.QLineEdit() authorEdit = QtGui.QLineEdit() reviewEdit = QtGui.QTextEdit() grid = QtGui.QGridLayout() grid.setSpacing(10) grid.addWidget(title, 1, 0) grid.addWidget(titleEdit, 1, 1) grid.addWidget(author, 2, 0) grid.addWidget(authorEdit, 2, 1) grid.addWidget(review, 3, 0) grid.addWidget(reviewEdit, 3, 1, 5, 1) self.setLayout(grid) self.setGeometry(300, 300, 350, 300) self.setWindowTitle('Review') self.show() def main(): app = QtGui.QApplication(sys.argv) ex = Example() sys.exit(app.exec_())if __name__ == '__main__': main()
依然是使用了Grid方法
