Applies To

fpSpreadPreview DLL control

Description

Set or return whether the user can use the mouse to zoom in or out while viewing pages.

Syntax

C

int SpvGetAllowUserZoom(HWND hWnd, BOOL FAR *lpValue);

int SpvSetAllowUserZoom(HWND hWnd, BOOL value);

C++

BOOL TPreview::GetAllowUserZoom(void);

int TPreview::SetAllowUserZoom(BOOL value);

Parameters

The following parameters are available:

Parameter Description
hWnd Window handle of the fpSpread control
value Specifies whether to allow the user to zoom

Remarks

By default, the fpSpreadPreview control lets users zoom in and out in the view of the sheet pages.

If you set the value parameter to FALSE for the SpvSetAllowUserZoom function, users cannot zoom in or out by clicking the mouse while the pointer is over a preview page. However, you can still provide other means in the interface to let users zoom, such as a button that changes the SpvSetZoomState function's value parameter.

Return Value

SpvGetAllowUserZoom: For C users, TRUE if the function completes successfully; FALSE otherwise. For C++ users, TRUE if the user can zoom in and out; FALSE otherwise.
SpvSetAllowUserZoom: TRUE if the function completes successfully; FALSE otherwise.
