How to make a column in QTableWidget read only?
I would like to have one column in QTableWidget
NOT editable.
flags
but could not manage to implement.Insert into the QTableWidget following kind of items:
QTableWidgetItem *item = new QTableWidgetItem();
item->setFlags(Qt::ItemIsSelectable|Qt::ItemIsEnabled);
Works fine!
EDIT:
QTableWidgetItem *item = new QTableWidgetItem();
item->setFlags(item->flags() ^ Qt::ItemIsEditable);
This is a better solution. Thanks to @priomsrb.
The result of using XOR depends on what the current state is. I'd suggest using
item->setFlags(item->flags() & ~Qt::ItemIsEditable);
to make sure editing is turned off regardless of the current setting.
I came to a better suggestion, just overwrite the cellDoubleClicked signal with a new SLOT. This is, if you want none of the cells to be modified
To apply @Narek's code to rows or columns, simply use a simple for loop and put a condition in to include the flags for rows/columns you do not want to be editable.
The following code reads a csv file into a QTableWidget:
if(!rowOfData.isEmpty()){
for (int x = 0; x < rowOfData.size(); x++)
{
rowData = rowOfData.at(x).split(",");
if(ui->table_Data->rowCount() <= x) ui->table_Data->insertRow(x);
for (int y = 0; y < rowData.size(); y++)
{
QTableWidgetItem *item = new QTableWidgetItem(rowData[y],QTableWidgetItem::Type);
if( y < 3 ) item->setFlags(item->flags() ^ Qt::ItemIsEditable); // Only disables the first three columns for editing, but allows the rest of the columns to be edited
ui->table_Data->setItem(x,y,item);
ui->table_Data->repaint();
}
}
}
