Retrieves the bounding rectangle of the drop-down component of the current split button control.

BOOL GetSplitSize(
     LPSIZE pSize
) const;



[out] pSize

Pointer to a SIZE structure that receives the description of a rectangle.

true if this method is successful; otherwise, false.

Use this method only with controls whose button style is BS_SPLITBUTTON or BS_DEFSPLITBUTTON.

When the split button control is expanded, it can display a drop-down component such as a list control or pager control. This method retrieves the bounding rectangle that contains the drop-down component.

This method initializes the mask member of a BUTTON_SPLITINFO structure with the BCSIF_SIZE flag, and then sends that structure in the BCM_GETSPLITINFO message that is described in the Windows SDK. When the message function returns, this method retrieves the bounding rectangle from the size member of the structure.
