- cleaned up join and split operations. Most noticable is operator callback
design, which should make a design based on user-less exec() first, then
wrap invoke() and modal() around it. The exec() should be callable with
only Context and properties.
- split now works again; and inversed as previously, if you drag from a
triangle (action zone) inside area it subdivides area as expected.
- dragging from triangle outside area, over an edge, joins areas
- split has been simplified, it had too many options... it could just work
simpler (now)
- 'action zone' now is an operator itself, a widget sending an ACTIONZONE event,
which can be handled by others (so other gestures can be added in action zone
too)
Still evaluating:
- context gets set where?
- code structure confuses... what are proper functions for operators?
- what is WM... should low level screen stuff more there?
- when do you send event, notifier?
- files grow to large, will clean
Oh yeah and docs, docs, docs. Coming! :)
==========
* Changed wmOperatorType, removing init/exit callbacks and adding cancel
callback, removed default storage in favor of properties. Defined return
values for exec/invoke/modal/cancel.
* Don't allocate operator on the stack, and removed operator copy for
handlers. Now it frees based on return values from callbacks, and just
keeps a wmOperator on the heap. Also it now registers after the operator
is fully finished, to get the correct final properties.
* Changed OP_get_* functions to return 1 if the property is found and 0
otherwise, gives more readable code in my opinion. Added OP_verify_*
functions to quickly check if the property is available and set if it's
not, that's common for exec/invoke.
* Removed WM_operatortypelist_append in favor of WM_operatortype_append
which takes a function pointer instead of a list, avoids macro's and
duplicating code.
* Fix a crash where the handler would still be used while it was freed by
the operator.
* Spacetypes now have operatortypes() and keymap() callbacks to abstract
them a bit more.
* Renamed C->curarea to C->area for consistency. Removed View3D/View2D/
SpaceIpo from bContext, seems bad to keep these.
* Set context variables like window/screen/area/region to NULL again when
leaving that context, instead of leaving the pointers there.
* Added if(G.f & G_DEBUG) for many of the prints, makes output a bit
cleaner and easier to debug.
* Fixed priority of the editors/interface module in scons, would otherwise
give link errors.
* Added start of generic view2d api.
* Added space_time with some basic drawing and a single operator to change
the frame.
add split area to screen manager
- RMB+ALT down on area edge activates
- mouse move interactively to area that is to be removed
- LMB to confirm, ESC to cancel
TODO:
- notifications for interactive drawing to mark area to remove
Some fixes
- uninitialized var warning.
- exit function of operators need to run before modal handler is removed if operator is used there.
- replaced MEM_mallocN with MEM_callocN to get rid of uninitialized mem for wmOperator.
- respect return value of wm_handler_operator_call() and break out of operator handling.
This commit adds split area to the window/screen manager.
- RMB down on area edge activates
- mouse move interactively moves areas through new edge.
- RMB up to confirm action
- ESCKEY or LMB to cancel.
This still crashes in some situations, but I'm on it!
Also will start using new operator property system by bdiego
- on mouse-over edge, you can drag area borders around.
- note it's a handerized system now, so it updates UI while you
move mouse.
Feedback needed:
- read bottom part of the screen_edit.c file. It's the proposed
method for adding tools and handlers. I think it's close, but
might need some tweaks.
- removed editors/area and put this all in screen
- added first python calls (note, a new c file for scriptlinks)
- added view3d editor callbacks (no drawing yet)
- added files in editors/interface
(Cmake and Scons has to be fixed, help welcome!)
- now areas/headers are being converted on file read
- note: previously saved 2.50 files will crash!!! (.B.blend)
- area regions are being drawn, first handler for cursor added (on edge)
- window duplicate and scale works correct for screen subdiv
Todos for me:
- need to fix things in syntax (function names) a bit still
- more operators for screen
- define how Context will work... still unresolved when it gets set
- docs!
Reviews of code structure is welcome!
There are also more todos now for others, but it can wait a couple of days
