Value | Meaning |
---|---|
PAINT_GROUP_BRUSH | Gets the Paintbrush properties. pProperty points to a PAINTBRUSH structure. |
PAINT_GROUP_SHAPE | Gets the Paint shape properties. pProperty points to a PAINTSHAPE structure. |
PAINT_GROUP_REGION | Gets the Paint region properties. pProperty points to a PAINTREGION structure. |
PAINT_GROUP_FILL | Gets the Paint fill properties. pProperty points to a PAINTFILL structure. |
PAINT_GROUP_TEXT | Gets the Paint fill properties. pProperty points to a PAINTTEXT structure. |
Pointer to a PAINTXXX structure to be updated with the specified property values. The type of structure that this parameter points to is indicated by the nGroup parameter.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes |
If this function is called after the class object handle is initialized, the default values will be returned. For more information about the default property values, refer to:
This example shows the minimum requirements for painting a rectangle shape
using some user defined properties.
