How to disable filtering option for a QTreeView or Model?

[NIXIN]

I am having a piece of code which deals with two QTreeView, where the items are added from left tree view to the right tree view. Here is a part of code:

MasterModel *model = new MasterModel;
LeftProxyFilterModel *leftModel = new LeftProxyFilterModel;
RightSelectedRowsFiletrModel *rightModel = new RightSelectedRowsFilterModel;

QTreeView *leftTreeView;
QTreeView *rightTreeView;

leftModel->setSourceModel(model);
rightModel->setSourceModel(leftModel);

leftTreeView->setModel(leftModel);
rightTreeView->setModel(rightModel);

Now for filtering some strings are set like this:

leftModel->setFilterWildcard(LineEdit->text());

This line is Filtering the contents of both the tree views, what I want is filtering option should be applicable only for left tree view. Can someone help me to achieve this???

@NIXIN
simply add a method to enable/disable filtering (bool).
In the filterAcceptsRow() method "return true" when filtering was disabled with your method.

@raven-worx How to implement enable/disable filtering(bool)

@NIXIN

class MySortFilterProxyModel : public QSortFilterProxyModel
{
    Q_OBJECT
    Q_PROPERTY(bool FilterEnabled READ isFilterEnabled WRITE setFilterEnabled )

public:
virtual bool filterAcceptsRow(int source_row, const QModelIndex & source_parent) const
{
      if( !m_IsFilterEnabled )
          return true;

      // your filtering code here
}

bool isFilterEnabled() const { return m_IsFilterEnabled };
void setFilterEnabled( bool enabled ) {
     if( m_IsFilterEnabled != enabled )
     {
           m_IsFilterEnabled = enabled;
           this->invalidate();
     }
}

private:
     bool m_IsFilterEnabled;
