Determines how the Rulers, PolyRulers, Cross-Products, and Protractors created by the automation object will be displayed.


#include "ltwrappr.h"

virtual L_INT LAnnAutomation::SetShowFlags(uShowFlags=0, uFlags=0)


L_UINT uShowFlags

Flag that indicates how to display the rulers. Possible values are:

Value Meaning
0 Display neither the ruler length or the ruler gauge.
ANNSHOW_LENGTH Display the ruler length.
ANNSHOW_GAUGE Display the ruler gauge.
ANNSHOW_TICMARKS Display the tic marks.

L_UINT uFlags

Flags that determine which objects to process. Most of the flags apply only to container objects. You can combine values when appropriate by using a bitwise OR ( | ). The following are valid values:

Value Meaning
0 Process only the specified object.
ANNFLAG_SELECTED [0x0001] Process only objects that have the selected property set to TRUE. For getting and setting the selected property, use the LAnnContainer::GetSelectItems and LAnnotation::SetSelected functions.
ANNFLAG_NOTTHIS [0x0004] Process only one level of objects within the specified container, not the container itself. If there are containers within the container, they are modified, but the objects within them are not.
ANNFLAG_RECURSE [0x0008] Process objects within a container, and within any subcontainers, down to any level.
ANNFLAG_NOTCONTAINER [0x0002] (Used with ANNFLAG_RECURSE) Process objects within containers, not the containers themselves.
ANNFLAG_NOINVALIDATE [0x0010] Do not invalidate the affected rectangle in the window. Use this to avoid generating unwanted paint messages.
ANNFLAG_CHECKMENU [0x0020] Process objects only if the ANNAUTOTEXT_MENU_SHOWRULER menu item has been selected.


Value Meaning
SUCCESS The function was successful.
< 1 An error occurred. Refer to Return Codes.


This function determines whether the length and gauge will be shown for the next Ruler, PolyRuler, Cross-Product, or Protractor object created in automated mode.

For Protractor objects, the default value for uShowFlags is 0. For the Ruler, PolyRuler, and Cross-Product objects the default value for uShowFlags is ANNSHOW_LENGTH | ANNSHOW_TICMARKS.
