python tablewidget 颜色_更改QTableWidget的默认选择颜色，并使其半透明

我有几乎相同的场景，但在instead中，我在单元格中有文本，我想要完全透明的选择(所以不改变背景颜色)

如果设置透明颜色，它将是实心的(qt中的bug？)所以我将文本设置为粗体(=selected)并转换选择样式

这里的代码，也许会有帮助//.h

#include

class SelectionControlDelegate : public QStyledItemDelegate

{

public:

SelectionControlDelegate(QObject* parent = 0);

void initStyleOption(QStyleOptionViewItem* option, const QModelIndex& index) const override;

};

//.cpp

SelectionControlDelegate::SelectionControlDelegate(QObject* parent) : QStyledItemDelegate(parent)

{

}

void SelectionControlDelegate::initStyleOption(QStyleOptionViewItem* option, const QModelIndex& index) const

{

QStyledItemDelegate::initStyleOption(option, index);

const bool selected = option->state & QStyle::State_Selected;

option->font.setBold(selected); // this will represent selected state

if (selected)

{

option->state = option->state & ~QStyle::State_Selected; // this will block selection-style = no highlight

}

}

// in widget class

...

_ui->tableView->setItemDelegate(new SelectionControlDelegate(this));

...

// when setting cell background, i would change also text color

QColor textColor = backgroundColor.value() <= 120 ? Qt::white : Qt::black; // if it is dark, text would be white otherwise black

// or you can compute invert color...

这是我的设想：5%和25%的项目被选中
