我希望能够在QPushButton
被点击时删除相应的行,我认为使用slots是合理的,但如何做到我不知道,如果您有任何想法,请分享一下,谢谢。
这是我的表格:
这是我向QTableWidget添加行的代码:
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
for(int i = 0; i<20;i++)
ui->tableWidget->insertRow(ui->tableWidget->rowCount());
QVector<QString>vec;
vec<<"first"<<"sec"<<"third"<<"for"<<"fif"<<"first"<<"sec"
<<"third"<<"for"<<"fif";
vec<<"first"<<"sec"<<"third"<<"for"<<"fif"<<"first"<<"sec"
<<"third"<<"for"<<"fif";
for(int i = 0; i<ui->tableWidget->rowCount();i++)
{
for(int j = 0; j<ui->tableWidget->columnCount();j++)
{
if(j == 0)
{
QWidget* pWidget = new QWidget();
QPushButton* btn_edit = new QPushButton();
btn_edit->setText("Remove");
QHBoxLayout* pLayout = new QHBoxLayout(pWidget);
pLayout->addWidget(btn_edit);
pLayout->setAlignment(Qt::AlignCenter);
pLayout->setContentsMargins(0, 0, 0, 0);
pWidget->setLayout(pLayout);
ui->tableWidget->setCellWidget(i, j, pWidget);
continue;
}
QTableWidgetItem*item = new QTableWidgetItem(vec[i]);
item->setFlags(item->flags() ^ Qt::ItemIsEditable);
ui->tableWidget->setItem(i, j, item);
}
}
}
