如何在pyqt4的QTableWidget中增加header标签的行高和行项的字体大小

Question

这里我想增加 header 标签的行高和单元格项目的字体大小。在我的代码中，我使用了 self.table.setRowHeight() 方法，但它不起作用。所以请告诉我他们有什么方法可以增加 header 标签的行高和单元格项目的字体大小。

下面是我的代码：

import sys
from PyQt4 import QtGui, QtCore


ROUNDED_STYLE_SHEET1 = """QPushButton {
     background-color: green;
     color: white;
     border-style: outset;
     border-width: 4px;
     border-radius: 15px;
     border-color: none;
     font: bold 12px;
     min-width: 10em;
     padding: 10px;
 }
"""

OVAL = """QPushButton {

      position: relative;
      width: 50px;
      height: 30px;
      margin: 20px 0;
      background: blue;
      border-radius: 48% / 25%;
      color: white;
      font: bold 10px;
}
"""

如果你想增加水平的高度header你必须使用setFixedHeight()，例如：

self.table.horizontalHeader().setFixedHeight(60)

如果你想增加单元格的字体你必须设置QTableWidget的setFont()方法:

fnt = self.table.font()
fnt.setPointSize(40)
self.table.setFont(fnt)
