QTreeWidget and column width

[Luigi Ferraris]

Hi to everyone.

I'm using QTreeWidget with more then one column and I want set column width.
As first solution I have used setColumnWidth(), but without solution; then....

I read Qt docs ( take a look here http://qt-project.org/doc/qt-4.8/qheaderview.html#ResizeMode-enum ) and I try this solution:

         oQtHorizontalHeader:setResizeMode( nCol-1, QHeaderView_Fixed )
         oQtHorizontalHeader:resizeSection ( nCol-1, 150 )

where oQtHorizontalHeader is QTreeWidget:header().

But this doesn't works: aaaarghhh!

In disagree with Qt docs I have used

         oQtHorizontalHeader:setResizeMode( nCol-1, QHeaderView_Custom )
         oQtHorizontalHeader:resizeSection ( nCol-1, 150 )


and I have settle QHeaderView_Custom to 4; and it works fine!!!??? Can be introduced this defined value? Or is there something problem somewhere?

I'm using Qt 4.8.4 lib, last qtcontribs and last harbour.

Cheers

Hi to everyone.
I have done another test using
         oQtHorizontalHeader:setResizeMode( nCol-1, QHeaderView_Interactive )

         oQtHorizontalHeader:resizeSection ( nCol-1, 150 )

But it doesn't works too....

About my previous message: is not the solution; using QHeaderView_Custom it set default section size (I think 100) :-(

Hi

I have done another test using
         oQtHorizontalHeader:setResizeMode( nCol-1, QHeaderView_Interactive )
         oQtHorizontalHeader:resizeSection ( nCol-1, 150 )
But it doesn't works too....

   WITH OBJECT oTree:Header()

      :resizeSection( 0, 150 )

      :resizeSection( 1, 250 )

      :resizeSection( 2, 150 )

   ENDWITH

Hi Pritpal, many thanks for your answer. Your code is (more or less) like mine. I think problem is related with the moment: at creation time works fine after perhaps not, but I'm not sure I must do more test.

Anyway, many thanks
