GridLayout with span

标签：

Widgets can span multiple columns or rows in a grid. In the next example we illustrate this.

ZetCode PyQt4 tutorial 

In this example, we create a bit
more complicated window layout using
the QtGui.QGridLayout manager.

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()

We create a window in which we have three labels, two line edits, and one text edit widget. The layout is done with the QtGui.QGridLayout.

grid = QtGui.QGridLayout()
grid.setSpacing(10)

We create a grid layout and set spacing between widgets.

grid.addWidget(reviewEdit, 3, 1, 5, 1)

If we add a widget to a grid, we can provide row span and column span of the widget. In our case, we make the reviewEdit widget span 5 rows.
