- Why is the per-application logbase being compiled out of MiNT for MTOS
- versions? I heard it had something to do with changing resolutions on
- a Falcon. Aren't all the apps closed anyway when the res is changed??
-
- I need a way to make VDI calls to a memory buffer, and it seems fitting
- that the multitasking system should be able to manage virtual screens.
- In fact, if logbase were inheritable, you could write a shell such as
- toswin for graphics apps (apps that normally write to the whole screen).
- Well, it would work if they just did VDI calls or just accessed the screen
- through the logbase pointer. It could work for some programs anyway, and
- it could allow developers to create apps that could work full-screen or
- in a window (maybe, I haven't though this through - I just want to be
- able to blit into a window from a buffer and write to this buffer via the
- VDI).
-
- MiNT makes Logbase per application, so I can do this without screwing up
- multitasking (although I wonder about MTOS toolbars, does MTOS use the logbase
- of the APP or the AES.SYS for its VDI ?? I assume a user-def object would
- use the app's logbase, but what about toolbars? Hmm ....
-
- Anyway, this feature is compiled out of MTOS since it can cause a problem
- if a Falcon changes resolutions. How does a Falcon change resolutions
- with applications still running?? I always thought the apps would have to
- be closed since the screen res is gonna change anyway!! There must be a
- solution to this problem. I just want the VDI to draw into my buffer!!
-
- Any help appreciated, here or by email.
