TreeView_GetVisibleCount

  • Article

This macro obtains the number of items that can be fully visible in the client window of a tree-view control. You can use this macro or send the TVM_GETVISIBLECOUNT message explicitly.

UINT TreeView_GetVisibleCount( hwnd);

Parameters

  • hwnd
    Handle to the tree view control.

Return Values

Returns 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.

Note that 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.
