TVM_SETINDENT message

Sets the width of indentation for a tree-view control and redraws the control to reflect the new width. You can send this message explicitly or by using the TreeView_SetIndent macro.

Parameters

wParam

Width, in pixels, of the indentation. If this parameter is less than the system-defined minimum width, the new width is set to the system-defined minimum.

lParam

Must be zero.

Return value

No return value.

Remarks

The system-defined minimum indent value is typically five pixels, but it is not fixed. To retrieve the exact value of the minimum indent on a particular system, send a TVM_SETINDENT message with wParam set to zero. Then send a TVM_GETINDENT message to retrieve the minimum indent value.
