how to stop it from closing in Modai Dialog (Enter key or ESC key )

[nishida_jp]

I am programming a c++ add-on using ArchiCAD27API + Visual Studio 2019 + Windows 10.

When I press the Enter key or ESC key in the Modai Dialog, the dialog closes.

Please tell me how to stop it from closing

Use the PanelCloseRequested of the PanelObserver.

See the AddRenameViewPointItemDialog.cpp of Navigator_Test example.

Thank you for your reply.
My program uses DGModalDialog() and I can't perform the processing you suggested.
If you know of any other ways, please let me know.

There is DG_MSG_CLOSEREQUEST message.
But unfortunately, it is not documetnted. I use C++ dialogs, and i dont know any details, sorry.
