* As a test, used by:
* Object buttons, tried to make it match the mockup.
* Text window header.
* Text window properties panel.
* Panel interaction with view2d is still problematic, need to make
this work properly still.
* Templates are very basic, the ones there are simple but already
can follow the object buttons mockup quite closely.
* It's based on a three level system: panels, templates and items.
To get an idea of what that means in practice, see:
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/UI_LayoutEngine#Panels.2C_Templates_and_Items
There was very little structure in this code, using many globals
and duplicated code. Now it should be better structured. Most
things should work, the main parts that are not back yet are the
python plugins and markers. Notes:
* Blenfont is used for drawing the text, nicely anti-aliased.
* A monospace truetype font was added, since that is needed for
the text editor. It's Bitstream Vera Sans Mono. This is the
default gnome terminal font, but it doesn't fit entirely well
with the other font I think, can be changed easily of course.
* Clipboard copy/cut/paste now always uses the system clipboard,
the code for the own cut buffer was removed.
* The interface buttons should support copy/cut/paste again now
as well.
* WM_clipboard_text_get/WM_clipboard_text_set were added to the
windowmanager code.
* Find panel is now a kind of second header, instead of a panel.
This needs especially a way to start editing the text field
immediately on open still.
* Operators are independent of the actual space when possible,
was a bit of puzzling but got it solved nice with notifiers,
and some lazy init for syntax highlight in the drawing code.
* RNA was created for the text editor space and used for buttons.
* Operators:
* New, Open, Reload, Save, Save As, Make Internal
* Run Script, Refresh Pyconstraints
* Copy, Cut, Paste
* Convert Whitespace, Uncomment, Comment, Indent, Unindent
* Line Break, Insert
* Next Marker, Previous Marker, Clear All Markers, Mark All
* Select Line, Select All
* Jump, Move, Move Select, Delete, Toggle Overwrite
* Scroll, Scroll Bar, Set Cursor, Line Number
* Find and Replace, Find, Replace, Find Set Selected,
Replace Set Selected
* To 3D Object
* Resolve Conflict
* Cleaned up UI_interface.h a bit, and added some comments to
organize things a bit and indicate what should be used when.
* uiMenu* functions can now be used to create menus for headers
too, this is done with a uiDefMenuBut, which takes a pointer
to a uiMenuCreateFunc, that will then call uiMenu* functions.
* Renamed uiMenuBegin/End to uiPupMenuBegin/End, as these are
specific to making popup menus. Will convert the other
conformation popup menu functions to use this too so we can
remove some code.
* Extended uiMenu functions, now there is is also:
BooleanO, FloatO, BooleanR, EnumR, LevelEnumR, Separator.
* Converted image window headers to use uiMenu functions, simplifies
menu code further here. Did not remove the uiDefMenu functions as
they are used in sequencer/view3d in some places now (will fix).
* Also tried to simplify and fix bounds computation a bit better
for popup menus. It tried to find out in advance what the size
of the menu was but this is difficult with keymap strings in
there, now uiPopupBoundsBlock can figure this out afterwards and
ensure the popup is within the window bounds. Will convert some
other functions to use this too.
Small cleanup in region-based cursor handling.
- callback was in spacetype, now in regiontype
- made screen listener catch ND_MODE notifier and
call the active region cursor callback, if it's there.
* API and usage is basically the same still.
* Panels were moved to region level. I first thought of keeping them at area
level, but having them at region level it's simpler to handle events and do
drawing, and also to integrate with view2d. They can still become area level
overlapping regions, if we make a floating (or docked) region that can
contain panels.
* Added back a few panels from the scene buttons for testing.
Issues still:
* The view2d handling and alignment refresh of panels is not correct yet in the
buttons window.
* I did not yet bring back the block handlers system. It was basically a system
that stored which panel was open and where the events for that panel would go.
Just a few functions, but not sure how it fits in 2.5.
* There was a case where dragging panels would not properly remove the window
level handler, but could not redo anymore even though I don't think I fixed
it.
* Some text in the panels goes past the end of the button, that is due to the
checkmark button drawing, not related to this commit.
Other UI code changes:
* Renamed interface.h to interface_intern.h for consistency.
* Fixed some issues with freeing of blocks when they changed due to context.
* uiDrawBlock now takes a context pointer (mostly for block drawextra).
Small area/space api fix: space->new() callbacks now require
Context pointer. Too many cases you want to initialize stuff...
Also: added dummy draw function for NLA channel region, was
too ugly.
Compile fix; MAXFLOAT is not defined uniformly on platforms.
Note for the coders:
ED_types.h: has editor wide defines and structs
ED_util.h: has editor wide functions
Both includes also are containing old cruft to get things
to compile (and work), for later cleanup.
Context API
This adds the context API as described here. The main practical change
now is that C is not longer directly accessible but has to be accessed
through accessor functions. This basically adds the implementation of
the API and adaption of existing code with some minor changes. The next
task of course is to actually use this design to cleanup of bad level
calls and global access, in blenkernel, blenloader.

Error, Warning and Debug Info Reporting
This adds the error reporting API as described here. It should help
clean up error() calls in non-ui code, but eventually can become used
for gathering messages for a console window, and throwing exceptions
in python scripts when an error happens executing something.

Now, preset view configurations are only to be used if they define all (scrollers not included) relevant settings for the view they are set for. This should be less confusing than in the previous situation with V2D_COMMONVIEW_TIMELINE stuff.
One implication of this though, is that all Animation Editors (for example), will have to define their own version of the relatively commonly shared info. However, given the great diversity in the range of settings each have, this should not be too much of an issue.
Also, added a 'standard' view config for main 'window' regions. At this stage, it is recommended that this view config should be used only as a placeholder template on which a set of custom settings could be based. I've put it into use for the buttons window/scripts window/info window so far.
Improved the View2D API so that initialising View2D data in init() callbacks (called on new regions and also on resizing regions) for regions is easier.
Added a few preset view configurations for use when initialising new views. Views with the V2D_IS_INITIALISED flag set will not be reinitialised in the init() callbacks. Currently, some of these configurations will set/override all settings (like V2D_COMMONVIEW_LIST and V2D_COMMONVIEW_HEADER), while other ones serve a more supplimentary role (i.e. V2D_COMMONVIEW_TIMELINE only sets the x-axis settings, relying on the region to have already set the relevant y-axis settings).
The future of such supplimentary configurations is yet to be seen, as I'm currently not sure whether they will cause the code to become too confusing, as you'd have to keep track of which settings belong/are set where. So far, only a few areas have been ported to use this. Tomorrow I'll check on a few more.
As this commit touches a lot of files, hopefully there aren't any critical bugs I've missed here.
Mouse cursors now work again
- centralized screen-level cursor changes, no more operator
running for it.
- spacetypes have callback to check/set individual cursor
types. Use notifier SCREEN_CHANGED to make sure it works
on mode changes etc.
- new calls WM_cursor_modal() and WM_cursor_restore() to
make temporarily cursor types during modes.
- used above for view2d cursors.
- depricated area "headbutofs" and "headbutlen", which is now fully
replaced with view2d handling.
- needed to add header default V2D_ALIGN_NO_NEG_Y, V2D_LOCKOFS_Y seems
to not do anything atm :)
- new: running blender in debug (blender -d) will print the current
handler and operator in use (not mousemove)
