TVM_SETITEMHEIGHT message

Sets the height of the tree-view items. You can send this message explicitly or by using the TreeView_SetItemHeight macro.

Parameters

wParam

New height of every item in the tree view, in pixels. Heights less than 1 will be set to 1. If this argument is not even and the tree-view control does not have the TVS_NONEVENHEIGHT style, this value will be rounded down to the nearest even value. If this argument is -1, the control will revert to using its default item height.

lParam
Must be zero.

Return value

Returns the previous height of the items, in pixels.

Remarks

The tree-view control uses this value for the height of all items. To modify the height of individual items, see the description of the iIntegral member of the TVITEMEX structure.
