有没有办法在 PyQT4 中使用循环创建按钮网格?
Is there a way to create a grid of buttons using a loop in PyQT4?
例如,具有以下效果的东西:
So for example, something that has the effect of:
for j in range(0, 10):
for k in range(0, 10):
grid.addbutton(j, k)
谢谢.
当然有.QGridLayout
可能有用在这种情况下.
Sure there is. QGridLayout
might be useful in this case.
这是一个最小的例子:
import sys
from PyQt4 import QtGui
app = QtGui.QApplication(sys.argv)
widget = QtGui.QWidget()
layout = QtGui.QGridLayout()
buttons = {}
for i in range(10):
for j in range(10):
# keep a reference to the buttons
buttons[(i, j)] = QtGui.QPushButton('row %d, col %d' % (i, j))
# add to the layout
layout.addWidget(buttons[(i, j)], i, j)
widget.setLayout(layout)
widget.show()
sys.exit(app.exec_())
结果:
