我有一个表格视图,其中每个单元格都有自定义文本颜色。选择行时,颜色将更改为默认的 highlightText 值(白色)。当行也被选中时,如何保持定义的 ForegroundRole 分配颜色?谢谢你的帮助。

您可能可以使用自定义委托来实现此目的。
试试这里的提示。
from PyQt4 import QtGui, QtCore
import sys
class CustomSelectColorDelegate(QtGui.QStyledItemDelegate):
def __init__(self, parent = None):
super(CustomSelectColorDelegate, self).__init__(parent)
def paint(self, painter, option, index):
painter.save()
# set background color
if option.state & QtGui.QStyle.State_Selected:
painter.setBrush(QtGui.QBrush(QtCore.Qt.white))
else:
painter.setBrush(QtGui.QBrush(QtCore.Qt.red))
painter.drawRect(option.rect)
# set text color
if option.state & QtGui.QStyle.State_Selected:
painter.setPen(QtGui.QPen(QtCore.Qt.red))
else:
painter.setPen(QtGui.QPen(QtCore.Qt.white))
value = index.data(QtCore.Qt.DisplayRole)
if value.isValid():
text = value.toString()
painter.drawText(option.rect, QtCore.Qt.AlignLeft | QtCore.Qt.AlignCenter, text)
painter.restore()
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
mw = QtGui.QWidget()
tableViewer0 = QtGui.QTableWidget()
newitem1 = QtGui.QTableWidgetItem('this is standard text')
newitem2 = QtGui.QTableWidgetItem('this is custom text')
tableViewer0.setColumnCount(2)
tableViewer0.insertRow(0)
tableViewer0.setItem(0, 0, newitem1)
tableViewer0.setItem(0, 1, newitem2)
customSelectColorDelegate = CustomSelectColorDelegate()
tableViewer0.setItemDelegateForColumn(1, customSelectColorDelegate)
vbox = QtGui.QVBoxLayout()
vbox.addWidget(tableViewer0)
mw.setLayout(vbox)
mw.show()
sys.exit(app.exec_())
