Implementing TableView with one editable CheckBox

[scarleton]

I am missing something here. The best I can figure is in the data() method of the model, check to see if the column is the one that should be a check box, if so and if the role is Qt::CheckStateRole, return either Qt::Checked or Qt::Unchecked.

I did this and it is displaying a checkbox, but it is still to the far left and the original value (zero or one) is also being displayed. When I click on the cell, the number is editable.

What am I missing?

Ok, I found this other thread which enlightened me to enhancing the flag method, too. Since my model extends the QSqlQueryModel, here is what is being returned for the check box column:

Qt::ItemIsEditable | Qt::ItemIsUserCheckable | Qt::ItemIsSelectable | Qt::ItemIsEnabled

I also tweaked what the data method was returning:

if(index.column() == _isInSlideShowIdx)
{
	if (role == Qt::CheckStateRole)
		return QSqlQueryModel::data(index, Qt::DisplayRole).toBool() ? Qt::Checked : Qt::Unchecked;
	else if( role == Qt::DisplayRole)
		return QVariant();
}

if(index.column() == _isInSlideShowIdx)
{
	if (role == Qt::CheckStateRole)
		return QSqlQueryModel::data(index, Qt::DisplayRole).toBool() ? Qt::Checked : Qt::Unchecked;
	else if( role == Qt::DisplayRole)
		return QVariant();
}

To copy to clipboard, switch view to plain text mode 

But I still have issues:

1. The check box is always on the left
2. When I click on the check box cell, it makes the space to the right of the check box an editbox control
3. When I added a delegate to create a check box editor, I had to still double click on the space to the right to make the editor active, and the editor is offset to the left by a pixel or two.

Any thoughts on how to fix this?

Hi scarleton,

perhaps this will help

ui->tableWidget->setEditTriggers(QAbstractItemView::SelectedClicked);

ui->tableWidget->setEditTriggers(QAbstractItemView::SelectedClicked);

To copy to clipboard, switch view to plain text mode

Hello,

Try void QAbstractItemView:penPersistentEditor ( const QModelIndex & index ) !

I think this is what you want !
