Qt - Access a checkbox in a table - c++

Question

I have a table and each row in the table has a checkbox in it's first column. I need to make it so I can detect which checkboxes are checked and delete those rows when a button is pressed.
QWidget * chkWidget = new QWidget();
QHBoxLayout *center = new QHBoxLayout();
center->setAlignment( Qt::AlignCenter );
center->addWidget( new QCheckBox );
chkWidget->setLayout( center );
ui->data_table->setCellWidget(rowCount,0, chkWidget);
Was this done right? If so how do I access the checkboxes at each row?

Answer 1

I talk about a QTableWidget. You can use a QList.You save your QCheckBox into this QList and use it, when there is some change
Maybe you should check out the documentation
QTableWidget: Link
QList: Link
Here is a solution. I cannot run it at the moment, so please tell me if it works. Please validate the row value. I am not sure if it's possible, that row can have the value -1 when you delete the last row ;)
#include "TestTableWidget.h"
#include "ui_TestTableWidget.h"
TestTableWidget::TestTableWidget(QWidget *parent) : QMainWindow(parent), ui(new Ui::TestTableWidget)
{
ui->setupUi(this);
tableWidget = new QTableWidget(this);
tableWidget->setColumnCount(1); // Just an example
ui->gridLayout->addWidget(tableWidget);
connect(tableWidget, SIGNAL(itemSelectionChanged()), this, SLOT(slotChange()));
for(int i = 1; i < 10; i++)
{
addRow("Row " + QString::number(i));
}
}
TestTableWidget::~TestTableWidget()
{
delete ui;
}
void TestTableWidget::addRow(QString text)
{
int row = tableWidget->rowCount();
qDebug() << "Current row count is " + QString::number(row);
// Add new one
QTableWidgetItem *item = new QTableWidgetItem(text);
tableWidget->insertRow(row);
tableWidget->setItem(row, 0, item);
// Add item to our list
}
void TestTableWidget::slotChange()
{
int row = tableWidget->currentRow();
qDebug() << "Change in table. Current row-index: " + QString::number(row);
// This value is zero-based, so you can use it in our list
}
