MonthCal_GetMinReqRect macro
Retrieves the minimum size required to display a full month in a month calendar control. Size information is presented in the form of a RECT structure. You can use this macro or send the MCM_GETMINREQRECT message explicitly.
Syntax
BOOL MonthCal_GetMinReqRect( HWND hwndMC, LPRECT lpRectInfo );
Parameters
- hwndMC
-
Type: HWND
Handle to a month calendar control.
- lpRectInfo
-
Type: LPRECT
Pointer to a RECT structure that will receive bounding rectangle information. This parameter must be a valid address and cannot be NULL.
Return value
Returns nonzero and MonthCal_GetMinReqRect receives the applicable bounding information if successful. Otherwise, the return is zero.
Remarks
The minimum required window size for a month calendar control depends on the currently selected font, control styles, system metrics, and regional settings. When an application changes anything that affects the minimum window size, or processes a WM_SETTINGCHANGE message, it should call MonthCal_GetMinReqRect to determine the new minimum size.
The top and left members of lpRectInfo will always be zero. The right and bottom members represent the minimum cx and cy required for the control.
