QGridLayout不同的列宽 [英] QGridLayout different column width

问题描述

我正在尝试创建如下所示的布局:

I am trying to create a layout looking like this:

 _________
|  |      |
|1 |   2  |
|__|______|
|  3 | 4  |
|____|____|

基本上，我希望第一行的单元格比单元格2薄，但是第二行的3和4号单元格应该具有相等的宽度.

Basically, I want cell number 1 the first row to be thinner that cell 2, but cells number 3 and 4 on the second row should have equal widths.

是否甚至可以在PyQt4中使用QGridLayout创建这样的布局?

Is it even possible to create a layout like this using QGridLayout in PyQt4?

推荐答案

QGridLayout的任务是创建该类型的结构，为此您必须使用以下函数:

The task of QGridLayout is to create that type of structure, for this you must use the function:

无效QGridLayout :: addWidget(QWidget *小部件，int fromRow，int fromColumn，int rowSpan，int columnSpan，Qt :: Alignment alignment = 0)

void QGridLayout::addWidget(QWidget * widget, int fromRow, int fromColumn, int rowSpan, int columnSpan, Qt::Alignment alignment = 0)

这是一个重载函数.

此版本将给定的小部件添加到单元格网格，跨多个 行/列.该单元格将从fromRow开始，fromColumn跨越 rowSpan行和columnSpan列.小部件将具有给定的 对齐.

This version adds the given widget to the cell grid, spanning multiple rows/columns. The cell will start at fromRow, fromColumn spanning rowSpan rows and columnSpan columns. The widget will have the given alignment.

如果rowSpan和/或columnSpan为-1，则小部件将扩展到 底部和/或右边缘.

If rowSpan and/or columnSpan is -1, then the widget will extend to the bottom and/or right edge, respectively.

示例:

import sys

from PyQt4.QtCore import *
from PyQt4.QtGui import *

app = QApplication(sys.argv)
w = QWidget()
glay = QGridLayout(w)
glay.addWidget(QLabel("1"), 0, 0)
glay.addWidget(QLabel("2"), 0, 1, 1, 3)
glay.addWidget(QLabel("3"), 1, 0, 1, 2)
glay.addWidget(QLabel("4"), 1, 2, 1, 2)

qsrand(QTime.currentTime().msec())

for label in w.findChildren(QLabel):
    color = QColor(qrand() % 256, qrand() % 256, qrand() % 256)
    label.setStyleSheet('.QLabel{{background: rgb({}, {}, {});}}'.format(color.red(), color.green(), color.blue()))

w.show()
sys.exit(app.exec_())
