COMPROPSHEETUI structure (compstui.h)

Artikel
11/24/2022

The COMPROPSHEETUI structure is used as an input parameter to CPSUI's ComPropSheet function, if the function code is CPSFUNC_ADD_PCOMPROPSHEETUI. All structure members must be supplied by the caller of ComPropSheet.

Syntax

typedef struct _COMPROPSHEETUI {
  WORD           cbSize;
  WORD           Flags;
  HINSTANCE      hInstCaller;
  LPTSTR         pCallerName;
  ULONG_PTR      UserData;
  LPTSTR         pHelpFile;
  _CPSUICALLBACK pfnCallBack;
  POPTITEM       pOptItem;
  PDLGPAGE       pDlgPage;
  WORD           cOptItem;
  WORD           cDlgPage;
  ULONG_PTR      IconID;
  LPTSTR         pOptItemName;
  WORD           CallerVersion;
  WORD           OptItemVersion;
  ULONG_PTR      dwReserved[4];
} COMPROPSHEETUI, *PCOMPROPSHEETUI;

Members

cbSize

Caller-supplied size, in bytes, of the COMPROPSHEETUI structure.

Flags

Optional caller-supplied bit flags, as described in the following list:

CPSUIF_ABOUT_CALLBACK

If set, the page's callback function (pointed to by the structure's pfnCallback member), supports CPSUICB_REASON_ABOUT, so CPSUI will call the callback function if the user clicks on the page's About button. (CPSUI supplies an About button for each treeview root node.)

CPSUIF_ICONID_AS_HICON

If set, the structure's IconID member contains an icon handle.

If not set, the IconID member contains an icon resource identifier.

CPSUIF_UPDATE_PERMISSION

If set, the page's option values can be modified by the user.

hInstCaller

Caller-supplied module instance handle, received by the DLL's entry point function.

pCallerName

Caller-supplied pointer to a NULL-terminated text string representing the application's name. (For a printer interface DLL, this should be the driver's name, such as "PostScript Driver".)

UserData

Optional caller-supplied value, which CPSUI places in a CPSUICBPARAM structure's UserData member when calling the function pointed to by pfnCallBack.

pHelpFile

Caller-supplied pointer to a NULL-terminated text string representing a path to a help file. For printer interface DLLs, this is typically the help file path obtained by calling GetPrinterDriver.

The help file is indexed by values contained in the HelpIndex member of OPTITEM structures.

pfnCallBack

Caller-supplied pointer to a _CPSUICALLBACK-typed callback function, which CPSUI calls when a user modifies the page's option values.

Can be used only if pDlgPage identifies a CPSUI-supplied DLGPAGE structure, or if the DlgProc member of an application-supplied DLGPAGE structure is NULL.

pOptItem

Caller-supplied pointer to an array of OPTITEM structures describing the page's options.

pDlgPage

This member specifies DLGPAGE structures that describe pages to be added to the property sheet. It can be either of the following:

A pointer to an array of DLGPAGE structures.
One of the pointers that is described in the following list. These pointers reference predefined DLGPAGE structures, supplied by CPSUI for use by printer interface DLLs.
- CPSUI_PDLGPAGE_ADVDOCPROP
  
  Defines one treeview page whose tab reads Advanced. For use only by a DrvDocumentPropertySheets function.
- CPSUI_PDLGPAGE_DOCPROP
  
  Defines three pages, whose tabs are Layout, Paper/Quality, and Advanced. The Advanced page is a treeview. For use only by a DrvDocumentPropertySheets function.
- CPSUI_PDLGPAGE_PRINTERPROP
  
  Defines one treeview page whose tab reads Device Settings. For use only by a DrvDevicePropertySheets function.
- CPSUI_PDLGPAGE_TREEVIEWONLY
  
  Defines one treeview page.

cOptItem

Caller-supplied number of OPTITEM structures pointed to by pOptItem.

cDlgPage

Caller-supplied number of DLGPAGE structures pointed to by pDlgPage. Not used if pDlgPage specifies a predefined CPSUI_PDLGPAGE-prefixed structure.

IconID

Caller-supplied, can be one of the following:

An icon resource identifier. This can be application-defined, or it can be one of the CPSUI-supplied, IDI_CPSUI-prefixed icon resource identifiers.
An icon handle. If a handle is specified, CPSUIF_ICONID_AS_HICON must be set in the Flags member.

The specified icon is displayed in the root node of the property sheet page's treeview.

pOptItemName

Caller-supplied pointer to a NULL-terminated string to be displayed in the root node of the property sheet page's treeview. For printer interface DLLs, this string typically represents a printer device type, such as "HP 4si".

CallerVersion

Caller-supplied version number, representing the calling application's current version. The high byte identifies the major version, and the low byte is the minor version. For example, a CallerVersion value of 0x310 specifies a caller version number of 3.16. The version number is displayed when a user clicks on a page's About button.

OptItemVersion

Caller-supplied version number, representing the root-level option item's current version. For printer interface DLLs, this typically represents a printer device version. The high byte identifies the major version, and the low byte is the minor version. For example, an OptItemVersion value of 0x3ff specifies a caller version number of 3.255. The version number is displayed when a user clicks on a page's About button.

dwReserved[4]

Reserved. This array must be set to zero.
