QTableView有corner button,占据水平和垂直标题之间的交集。单击此按钮将选择表格中的所有单元格。我想知道的是,是否可以设置此按钮的文本,如果可以,如何设置?

我已经使用PyQt 5.3实现了一个可行的解决方案,它的代码却少得惊人。我的解决方案基于Qt中心this question发布的代码。
from PyQt5 import QtWidgets, QtCore
class TableView(QtWidgets.QTableView):
"""QTableView specialization that can e.g. paint the top left corner header.
"""
def __init__(self, nw_heading, parent):
super(TableView, self).__init__(parent)
self.__nw_heading = nw_heading
btn = self.findChild(QtWidgets.QAbstractButton)
btn.setText(self.__nw_heading)
btn.setToolTip('Toggle selecting all table cells')
btn.installEventFilter(self)
opt = QtWidgets.QStyleOptionHeader()
opt.text = btn.text()
s = QtCore.QSize(btn.style().sizeFromContents(
QtWidgets.QStyle.CT_HeaderSection, opt, QtCore.QSize(), btn).
expandedTo(QtWidgets.QApplication.globalStrut()))
if s.isValid():
self.verticalHeader().setMinimumWidth(s.width())
def eventFilter(self, obj, event):
if event.type() != QtCore.QEvent.Paint or not isinstance(
obj, QtWidgets.QAbstractButton):
return False
# Paint by hand (borrowed from QTableCornerButton)
opt = QtWidgets.QStyleOptionHeader()
opt.initFrom(obj)
styleState = QtWidgets.QStyle.State_None
if obj.isEnabled():
styleState |= QtWidgets.QStyle.State_Enabled
if obj.isActiveWindow():
styleState |= QtWidgets.QStyle.State_Active
if obj.isDown():
styleState |= QtWidgets.QStyle.State_Sunken
opt.state = styleState
opt.rect = obj.rect()
# This line is the only difference to QTableCornerButton
opt.text = obj.text()
opt.position = QtWidgets.QStyleOptionHeader.OnlyOneSection
painter = QtWidgets.QStylePainter(obj)
painter.drawControl(QtWidgets.QStyle.CE_Header, opt)
return True

您可以通过从QTableWidget中找到一个孩子来在角落按钮上添加文本,并使用以下垂直布局向其添加QLabel。
QAbstractButton* button = qFindChild< QAbstractButton* >(TableWidget);
if (button)
{
QVBoxLayout* lay = new QVBoxLayout(button);
lay->setContentsMargins(0, 0, 0, 0);
QLabel* label = new QLabel("No");
label->setStyleSheet("QLabel {font-face: ArialMT; font-size: 10px; color: #FFFFFF; font-weight: bold; }""QToolTip { color: #ffffff; background-color: #000000; border: 1px #000000; }");
label->setAlignment(Qt::AlignCenter);
label->setToolTip("Text");
label->setContentsMargins(2, 2, 2, 2);
lay->addWidget(label);
}
