Changing the order of columns in QTreeView

Hello,

I was just wondering how to change the order of columns as they appear in QTreeView when using QDirModel. Here is a snippet of code:

Qt Code:

Switch view

// Declare the new objects.
	Directory_Model = new QDirModel;
	File_Path = new QString;
 
	// Set the file system structure parameters.
	Directory_Model->setFilter(QDir::AllDirs);
	Directory_Model->setSorting(QDir::Time);
 
	// Set the tree model (visual) parameters.
	this->QTreeView::setModel(Directory_Model);
	this->setColumnHidden(1,1);
	this->setColumnHidden(2,1);
	//this->setColumnHidden(3,1); //This crashes the widget.  Why does this happen?

// Declare the new objects.
	Directory_Model = new QDirModel;
	File_Path = new QString;

	// Set the file system structure parameters.
	Directory_Model->setFilter(QDir::AllDirs);
	Directory_Model->setSorting(QDir::Time);

	// Set the tree model (visual) parameters.
	this->QTreeView::setModel(Directory_Model);
	this->setColumnHidden(1,1);
	this->setColumnHidden(2,1);
	//this->setColumnHidden(3,1); //This crashes the widget.  Why does this happen?

To copy to clipboard, switch view to plain text mode

As it stands, I can see the directory tree, and then the modification time - in that order from left to right. I want this order reversed... how can this be done?

JS.
