QTreeView middle column fill width space instead of last column

Question

How can do this:

I already tried this way:

view->header()->setResizeMode(INDEX_COLUMN_SKU, QHeaderView::Interactive);
view->header()->setResizeMode(INDEX_COLUMN_NAME, QHeaderView::Stretch);
view->header()->setResizeMode(INDEX_COLUMN_QUANTITY, QHeaderView::Interactive);
view->header()->setResizeMode(INDEX_COLUMN_PRICE, QHeaderView::Interactive);

but does not work.

Answer 1

Did you remember to view->header()->setStretchLastSection(false)?

Here are some examples:

Default Behavior

Just disabling stretch on the last column:

treeView->header()->setStretchLastSection(false); 

Both attributes combined:

treeView->header()->setStretchLastSection(false); treeView->header()->setResizeMode(1, QHeaderView::Stretch);    

From QT5 onwards:

treeView->header()->setStretchLastSection(false); treeView->header()->setSectionResizeMode(1, QHeaderView::Stretch); //! qt5 api change
