将QPushButton添加到QTableWidget中的QTableWidgetItem中,如何使其成为Qt :: AlignHCenter

Question

for(int i=0; i<page.size(); i++){
    User user= Poco::AnyCast<User>(*it);
    ui.table->setItem(i,0,new QTableWidgetItem(user.userName)); 
    ui.table->setItem(i,1,new QTableWidgetItem(user.sex));
    ui.table->setItem(i,2,new QTableWidgetItem(user.age));

    QPushButton* btn_edit = new QPushButton();
    btn_edit = new QPushButton();
    btn_edit->setText("Edit");
    ui.table->setCellWidget(i,3,(QWidget*)btn_edit);

    ++it;
}

我使用函数setCellWidget()将QPushButton添加到单元格中,我知道,如果它是QTableWidgetItem,我可以使用:

ui.table->item(0,3)->setTextAlignment(QT::AlignHCenter)

但它是一个小工具,

QTableWidgetItem item = ui.table->item(0,3); 

该项为null.

我可以通过使用获得细胞

ui.table->cellWidget(0,3).

如何使按钮在单元格中居中？

试试这个:

QWidget* pWidget = new QWidget();
QPushButton* btn_edit = new QPushButton();
btn_edit->setText("Edit");
QHBoxLayout* pLayout = new QHBoxLayout(pWidget);
pLayout->addWidget(btn_edit);
pLayout->setAlignment(Qt::AlignCenter);
pLayout->setContentsMargins(0, 0, 0, 0);
pWidget->setLayout(pLayout);
ui.table->setCellWidget(i, 3, pWidget);
