setting columnWidth and column header dynamically

[adms]

hi every body,
in extjs3 we used the following functions to set proprieties:

var colMod = grid.getColumnModel();
colMod.setColumnHeader(1, 'new header');
colMod.setColumnWidth(1, 144);

but how to do it in extjs4 ?????????
thanks

Here's one way:

    var col = grid.headerCt.getHeaderAtIndex(1);
    col.setText('new header');
    col.setWidth(144);

thanks for reply,
the following code is working fine

var col = grid.headerCt.getHeaderAtIndex(2);
col.setText('new header');

but the statement:

col.setWidth(144);

sets the new width of the column only if the new width is grater than the old width,
but if the new width is smaller than the old width , no change in column width why??

Does the column have a flex config?

If it does you'll have to set it to 0 (zero) otherwise the width of the column can only be greater than the calculated width.

    var col = grid.headerCt.getHeaderAtIndex(1);
    col.setText('new header');
    col.flex = 0;
    col.setWidth(50);

sorry twaindev, I still have the same problem,
my column configuration is:

{
header : 'Name',
width:120,
dataIndex : 'name',
}

var col = grid.headerCt.getHeaderAtIndex(1);
col.setText('new header'); //works fine
col.flex = 0;
col.setWidth(50); // no result , can't be less than the old width(120)
