QTreeWidget::setModel() - Changing the model of the QTreeWidget is not allowed.

[mochen]

Hi,

I wrote a simple Qt program, When I run the program, it told me:

QTreeWidget::setModel() - Changing the model of the QTreeWidget is not allowed.

The code just like below:

dir_model_ = new QDirModel(this);
 
// enable drag and drop
dir_model_->setReadOnly(false);
 
tree_view_ = new QTreeWidget(this);
tree_view_->setModel(dir_model_);

dir_model_ = new QDirModel(this);
 
// enable drag and drop
dir_model_->setReadOnly(false);

tree_view_ = new QTreeWidget(this);
tree_view_->setModel(dir_model_);

To copy to clipboard, switch view to plain text mode 

I try to search Qt document and google, but I can not find any clue. How to solve this issue ?

Thanks.
