New: Custom region draw callbacks.
For Martin: an example is now in space_view3d/view3d_edit.c
On middlemouse rotate view, it draws a small square in center.
It works likes this:
#include "ED_space_api.h"
handle= ED_region_draw_cb_activate(region->type, drawfunc, type)
and to stop it:
ED_region_draw_cb_exit(region->type, handle)
drawfunc is of type (const bContext *C, ARegion *ar)
currently it gets called only as type REGION_DRAW_POST, later we
can add more (PRE, POST_XRAY, POST_2D, etc).
For correct usage, these calls should return leaving view transform
unaltered.
- basic drawing of list and thumbnail view (switchable through 'favourits' icon in header)
- selection of files and directories (bookmarks) works with the RMB (right mouse button)
- load operator for files still unstable (no check for correct file type) and incomplete. (WM_operator_free missing)
immediate TODOS:
- fix load file operator
- finish drawing of buttons in header
- drawing of detailed list with all file info.
- finish selection and execute operators (LMB and MMB execute)
later todos:
- parent dir
- keymap for all the shortcuts
- append/link and databrowse
- ...
The basics for InfoSpace.
Also added InfoSpace data to area by default, older files allowed to
have nothing here (space empty). (prevents reported crasher in switching
space info to others).
Also: added ifdeffed code in readfile.c to debug missing memory frees
from data read from files. (instead of "data from SCR" it will print
the actual struct names).
