python tablewidget 颜色_【整理】PyQt如何修改QTableView中表格颜色即如何修改QModelIndex颜色 | 勤奋的小青蛙...

生活随笔收集整理的這篇文章主要介紹了 python tablewidget 颜色_【整理】PyQt如何修改QTableView中表格颜色即如何修改QModelIndex颜色 | 勤奋的小青蛙... 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

修改顏色，整理有兩種方法，其中第一中方法是對index設置role，另外一個方法是在data的函數里根據role進行返回顏色

第一種方法：對index設置role

參考鏈接：

示例代碼：

QModelIndex vIndex = model()->index(mLastIndex,0);

model->setData(vIndex, QBrush(Qt::red), Qt::ForegroundRole);

第二種方法：重寫data方法，根據role進行判斷，返回顏色

示例代碼：

QVariant MyModel::data ( const QModelIndex & item, int role ) const

{

//change the background color

if (role == Qt::BackgroundRole)

{

return QColor(255, 0, 0);

}

return QSortFilterProxyModel::data(item, role);

}

下面是根據這第二種方法，寫出來的一個PyQt的示例，所有代碼如下：

''' pqt_tableview3.py

using QAbstractTableModel to present tabular data

allow table sorting by clicking on the header title
