EVENT_CUSTOM
EVENT_CUSTOM(pszName,pfnFire,vtsParams)
Parameters
pszName
The name of the event.
pfnFire
The name of the event firing function.
vtsParams
A space-separated list of one or more constants specifying the function’s parameter list.
Remarks
Use the EVENT_CUSTOM macro to define an event-map entry for a custom event.
The vtsParams parameter is a space-separated list of values from the VTS_ constants. One or more of these values separated by spaces (not commas) specifies the function’s parameter list. For example:
VTS_COLOR VTS_FONT
specifies a list containing a short integer followed by a BOOL.
The VTS_ constants and their meanings are as follows:
| Symbol | Parameter Type |
| VTS_I2 | short |
| VTS_I4 | long |
| VTS_R4 | float |
| VTS_R8 | double |
| VTS_COLOR | OLE_COLOR |
| VTS_CY | CURRENCY |
| VTS_DATE | DATE |
| VTS_BSTR | const char* |
| VTS_DISPATCH | LPDISPATCH |
| VTS_FONT | IFontDispatch* |
| VTS_HANDLE | HANDLE |
| VTS_SCODE | SCODE |
| VTS_BOOL | BOOL |
| VTS_VARIANT | const VARIANT* |
| VTS_PVARIANT | VARIANT* |
| VTS_UNKNOWN | LPUNKNOWN |
| VTS_OPTEXCLUSIVE | OLE_OPTEXCLUSIVE |
| VTS_PICTURE | IPictureDisp* |
| VTS_TRISTATE | OLE_TRISTATE |
| VTS_XPOS_PIXELS | OLE_XPOS_PIXELS |
| VTS_YPOS_PIXELS | OLE_YPOS_PIXELS |
| VTS_XSIZE_PIXELS | OLE_XSIZE_PIXELS |
| VTS_YSIZE_PIXELS | OLE_YSIZE_PIXELS |
| VTS_XPOS_HIMETRIC | OLE_XPOS_HIMETRIC |
| VTS_YPOS_HIMETRIC | OLE_YPOS_HIMETRIC |
| VTS_XSIZE_HIMETRIC | OLE_XSIZE_HIMETRIC |
| VTS_YSIZE_HIMETRIC | OLE_YSIZE_HIMETRIC |
Note Additional variant constants have been defined for all variant types, with the exception of VTS_FONT and VTS_PICTURE, that provide a pointer to the variant data constant. These constants are named using the VTS_Pconstantname convention. For example, VTS_PCOLOR is a pointer to a VTS_COLOR constant.
