Flags on a view.
| Enumerator | |
|---|---|
| F_none | everything for this view is static (the VESA-FB case) |
| F_set_buffer | buffer object for this view can be changed |
| F_set_buffer_offset | buffer offset can be set |
| F_set_bytes_per_line | bytes per line can be set |
| F_set_pixel | pixel type can be set |
| F_set_position | position on screen can be set |
| F_dyn_allocated | View is dynamically allocated. |
| F_set_background | Set view as background for session. |
| F_set_flags | Set view flags (.
|
| F_fully_dynamic | Flags for a fully dynamic view. |
Property flags of a view.
Such flags can be set or deleted with the F_set_flags operation using the set_info() method.
