dev_unmap_prog — 隐藏主窗口。
dev_unmap_prog 已过时,仅出于向后兼容性考虑而保留。 New applications should use
dev_close_tool with ToolId set to
'program_window' instead.
dev_unmap_prog( : : : )
dev_unmap_prog hides in MDI mode the main window and in SDI mode the
program window so that it is no longer visible.
It can be shown again by dev_map_prog。
Attention: after hiding the main window there is no opportunity to enter
and execute the dev_map_prog operator.
So take care that dev_unmap_prog is only executed in continuous mode
with a reachable dev_map_prog operator.
此算子不支持代码导出。
dev_unmap_prog 始终返回 2 ( H_MSG_TRUE )。
