virtual L_INT LAnnRuler::SetShowFlags(uShowFlags=0, uFlags=0)
Determines how the Rulers, PolyRulers, Cross-Products, and Protractors created by the automation object will be displayed.
Flag that indicates how to display the rulers. Possible values are:
|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.|
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:
|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.|
|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.
The default value for uShowFlags is:
|Ruler, PolyRuler, and Cross-Product||ANNSHOW_LENGTH | ANNSHOW_TICMARKS|
For an example, refer to LAnnRuler::GetDistance.
