QComboBox下拉框放一个QTableWidget后，addItem无效，具体代码如下：

复制代码

cbBox = new QComboBox(this);
cbBox->setStyleSheet("QComboBox{border-image:url(:/image/drive/bgk_combobox.png);color:#003CA6;border:none;}"
"QComboBox QAbstractItemView{background-color:#FAFAFA; border:2px solid #003CA6; border-radius:5px; color:#003CA6; height:25px;outline: 0px;}"
"QComboBox QAbstractItemView::item{background-color:#FAFAFA; color:#003CA6; height:25px;}"
"QComboBox QAbstractItemView::item:hover{background-color:#003CA6; color:white; height:25px;}"
"QComboBox QAbstractItemView::item:selected{background-color:#003CA6; color:white; height:25px;}"
"QComboBox::drop-down {border: none;}"
"QComboBox::down-arrow {image:url(:/res/down_arrow.png);padding: 0 14 0 0;}");
cbBox->addItem(QString("Values")); //此处在QComboBox上未显示
QStyledItemDelegate *itemDelegate = new QStyledItemDelegate();
cbBox->setItemDelegate(itemDelegate);
cbBox->resize(200, 30);
QTableWidget *tableWidget = new QTableWidget(1,2);
tableWidget->verticalHeader()->setVisible(false);
tableWidget->horizontalHeader()->setVisible(false);
tableWidget->setShowGrid(false);
for(int i = 0; i < 1; ++i)
{
//tableWidget->setRowHeight(i, comboBox->width()/2);
tableWidget->setColumnWidth(i, cbBox->width()/2);
for(int j = 0; j < 2; ++j)
{
if(j == 0)
{
btn1 = new QPushButton;
btn1->setFixedSize(cbBox->width()/2, cbBox->height());
btn1->setText(QString("Hex"));
connect(btn1, &QPushButton::clicked, this, &combobox::onClickedBtn1);
tableWidget->setCellWidget(i, j, btn1);
btn1->installEventFilter(this);
}
else
{
btn2 = new QPushButton;
btn2->setFixedSize(cbBox->width()/2, cbBox->height());
btn2->setText(QString("Dec"));
connect(btn2, &QPushButton::clicked, this, &combobox::onClickedBtn2);
tableWidget->setCellWidget(i, j, btn2);
btn2->installEventFilter(this);
}
}
}
cbBox->setModel(tableWidget->model());
cbBox->setView(tableWidget);
