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.
