This message retrieves the number of items that can be fully visible in the client window of the tree-view control. You can send this message explicitly or by using the TreeView_GetVisibleCountmacro.

Syntax

lParam = 0;

Return Value

The return value indicates the number of items that can be fully visible in the client window of the tree view control.

Remarks

The number of items that can be fully visible may be greater than the number of items in the control. The control calculates this value by dividing the height of the client window by the height of an item.

The return value is the number of items that can be fully visible. If you can see all of 20 items and part of one more item, the return value is 20.
