1. move方法
html
import sys from PyQt4 import QtGui class 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方法移动建立对象的位置。能够看到在使用Qlabel方法建立了一个label以后,使用期其move方法讲这个label移动到了特定的位置python
2. 窗口的layout方法app
import sys from PyQt4 import QtGui class 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 分别表明横向和纵向的位置。布局
3. 经过坐标直接放置窗口ui
import sys from PyQt4 import QtGui class 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,直接经过坐标来定义Button的位置。注意(i,j)中数字的大小是用来表示前后顺序的,其自己并无特殊意义。咱们稍微修改一下代码:spa
import sys from PyQt4 import QtGui class 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 sys from PyQt4 import QtGui class 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()
在运行以后咱们获得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。。。)code
(关于Zip,新手可参见 http://www.cnblogs.com/BeginMan/archive/2013/03/14/2959447.html) htm
import sys from PyQt4 import QtGui class 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方法对象
