TreeWidget column width
Message 1 in thread
Hi,
I have three columns in my QTreeWidget. I want width of first one to
keep expanding, whereas width of 2nd and 3rd to be fixed. The header in
my Tree Widget is hidden so user can never change the width.
I write following code:
_ui->treeWidget->header()->setResizeMode(0,QHeaderView::Stretch);
_ui->treeWidget->header()->setResizeMode(1,QHeaderView::Interactive);
_ui->treeWidget->header()->setResizeMode(2,QHeaderView::Interactive);
_ui->treeWidget->header()->resizeSection(1, 40);
_ui->treeWidget->header()->resizeSection(2, 40);
What I expect is the First column take all extra space except 40+40 from
the Column 2 and Column3, but the result is not so.
Can any one please tell me how to "make width of first column to keep
expanding, whereas width of 2nd and 3rd to be fixed"
Thanks.

Hi
You should try overloading the forms resizeEvent() and set the column
widths there.
Doing that works for me anyway...
