How to set the width of one column in treeview to be fixed and the other colume to be auto fit while window resized?

[remember2015]

One problem in coding with treeview:
@public class ReportGrid extends QTreeWidget {
public ReportGrid (QWidget parent) {
super(parent);
this.setRootIsDecorated(false);
this.setAlternatingRowColors(true);
ArrayList<String> labels = new ArrayList<String>();
labels.add("Description");
labels.add("Requird");
this.setHeaderLabels(labels);
header().setResizeMode(QHeaderView.ResizeMode.Interactive);
//this.setModel(model);
this.setColumnWidth(0, 200);
this.setColumnWidth(1, 20);
}
}@
I want set the "Description" column 200px min width and "Required" column to be 20px width fixed(it contains an icon).
But while window resizing the column “Requird” expands.
Thanks.

use header().setStretchLastSection(true);
and remove header().setResizeMode(QHeaderView.ResizeMode.Interactive);
