Python win32gui 模块，PyMakeBuffer() 实例源码

我们从Python开源项目中，提取了以下14个代码示例，用于说明如何使用win32gui.PyMakeBuffer()。

def UnpackNMITEMACTIVATE(lparam):
    format = _nmhdr_fmt + _nmhdr_align_padding
    if is64bit:
        # the struct module doesn't handle this correctly as some of the items
        # are actually structs in structs, which get individually aligned.
        format = format + "iiiiiiixxxxP"
    else:
        format = format + "iiiiiiiP"
    buf = win32gui.PyMakeBuffer(struct.calcsize(format), lparam)
    return _MakeResult("NMITEMACTIVATE hwndFrom idFrom code iItem iSubItem uNewState uOldState uChanged actionx actiony lParam",
                       struct.unpack(format, buf))

# MENUITEMINFO struct
# http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/WinUI/WindowsUserInterface/Resources/Menus/MenuReference/MenuStructures/MENUITEMINFO.asp
# We use the struct module to pack and unpack strings as MENUITEMINFO
# structures.  We also have special handling for the 'fMask' item in that
# structure to avoid the caller needing to explicitly check validity
# (None is used if the mask excludes/should exclude the value)
