void CSftTree::SetResizeHeader(BOOL fSet = TRUE);
BOOL CSftTreeSplit::GetResizeHeader() const;
void CSftTreeSplit::SetResizeHeader(BOOL fSet = TRUE);

Parameters

hwndCtl

The window handle of the tree control.

fSet

Set to TRUE to enable header and column resizing, otherwise set to FALSE.

Returns

GetResizeHeader returns TRUE if headers are resizable using the mouse, otherwise FALSE is returned.

Comments

The GetResizeHeader and SetResizeHeader functions define whether columns are resizable by the user.

Columns can only be resized by the user if column headers are visible (see SetShowHeader).
