L_LTANN_API L_INT L_AnnSetFontName(hObject, pFontName, uFlags)
Sets the font of one or more annotation objects. You specify the name of the font in a character string.
Handle to the annotation object.
The character string containing the name of the font to assign.
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 L_AnnGetSelected and L_AnnSetSelected 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_FONT menu item has been selected. |
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
This function applies to multiple and selected objects based on values of the uFlags
parameter.
This function does not affect objects that do not have this property or that do not let you change the property. For descriptions of the various types of objects and their properties, refer to Types of Annotations.
