how to hide checkbox of QStandardItem

[Scarab]

Hello,

is it possible to hide the checkbox of a QStandardItem if it was checkable in the past?

I create my items with item->setCheckable(false); and there is no checkbox visible.
Once i set item->setCheckable(true); the checkbox becomes visible... ok so far.
The problem is when i try to set an Item to be uncheckable again the checkbox keeps being visible.

I tried this:

item->pq_tree_item->setCheckable(false);
item->pq_tree_item->setTristate(false);
item->pq_tree_item->setUserTristate(false);
item->pq_tree_item->setEditable(false);

and this:

item->pq_tree_item->setFlags(0);

but it doesn't work.

item->pq_tree_item->setData(QVariant(),Qt::CheckStateRole);

Looks kinda pulled out of the hat and probably should be documented better but it's quite clear if you look at the source

Thank you! It works like a charm.

this is the code i am using to backup the previous check state:

Init:

tmp->setData( QVariant(Qt::Checked), ROLE_TREE_BACKUP_CHECKSTATE);
tmp->setData( QVariant(),Qt::CheckStateRole);
tmp->setFlags( Qt::ItemIsEnabled | Qt::ItemIsSelectable );

Hide:

QVariant backup = item->data(Qt::CheckStateRole);
if( backup.isValid() && !backup.isNull() ) item->setData( backup , ROLE_TREE_BACKUP_CHECKSTATE);
item->setData( QVariant(),Qt::CheckStateRole);
item->setFlags( Qt::ItemIsEnabled | Qt::ItemIsSelectable );

Show:

item->setData(  item->data(ROLE_TREE_BACKUP_CHECKSTATE), Qt::CheckStateRole);
item->setFlags( Qt::ItemIsEnabled | Qt::ItemIsSelectable | Qt::ItemIsUserCheckable );
