Value |
Meaning |
|
|
0 |
Process only the specified object. |

|
|
ANNFLAG_NOTTHIS |

[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 |

Returns
|
SUCCESS |
The function was successful. |
|
< 1 |

Comments
You use the Windows COLORREF data type to specify the color. For example, you can use the L_GetPixelColor function or the Windows RGB macro to get a color value.
This function applies to multiple and selected objects based on values of the uFlags parameter.
To see how the foreground color relates to the fill modes, refer to Illustration of Fill Options for Annotations.
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.
