This is done by adding a new button type, GRIP, similar to other numbuttons
(scroll, slider, ...), which here controls the preview height.
Then, we add a new DNA struct to be able to save that height in Blend files
(note I choose not to use Panel struct for this, because we would then have the
same limitation we used to have with uiLists, only one preview per panel
and no preview outside panel).
This implies a change to template_preview UI RNA/py API (each preview needs an ID),
but this is backward compatible, as by default datablock type will be used if no ID is
given (which means e.g. all material previews with no ID will have same height).

- works by defining panel categories, currently restricted to the toolbar.
- no panels define bl_categories yet, so no user visible changes since tabs only show when there are multiple.
- panel pinning is available in rmb menu or alt+lmb.
Thanks to Brecht for the reviews. :)
This commit adds a show/hide extension below each uiList, containing by default an option to filter and/or reorder items by name (and to reverse those filtering and reordering).
Each derived uiList class in Python can define more specific filtering by implementing callbacks: the draw_filter() function to draw options in UI, and the filter_items() function to effectively filter/reorder items.
Note: the advanced options for vgroups shown as "proof od concept" in patches do not go in trunk for now, we have to find a better way to get those vgroups info for UI code, we can't afford to loop over each vertex here!
And doc (release notes and uiList example) is still to be updated, will do this in next days.
Many thanks to Brecht for the review!
* You can now drag-resize uiLists (in default or grid layouts).
** Note about "default" size: when you drag below minimal size of the uiList, it will automatically reset to automatic sizing (i.e. size between rows and maxrows, depending on the number of items to show). This often means (e.g. in Materials list with many mat slots) that the list will grow again to maxrows!
* Grid uiLists now have a customizable number of columns (previously it was a fixed value of 9), and they will respect the rows/maxrows settings as well (i.e. show a scrollbar when needed), instead of growing indefinitly!
They were caused by not having a free_windowmanager_cb set and by not having registered SpaceTypes, which meant data allocated for thosse SpaceTypes could not be freed. These were solved by defining a free_windowmanager_cb for the player that just frees wmWindows, and by making sure we only allocate memory for registered SpaceTypes.
This means you can for example, uv unwrap in quad-view and change settings in the toolbar without defaulting back to the first quad-view region available.
This may be displayed to the user later, for now this is set on executing registrable operators.
Otherwise it'll be nasty crashes when, say, adding and removing
screens with lists visible on the screen.
Thanks Ton for assisting looking into this issue :)
When rendering, during processing scene data, drawing in 3d window
is now locked. Can get extended to more areas in UI easily.
At least this solves all crashes with conflicting memory access in
render && 3d drawing. Deleting objects via operators or delete
modifiers isn't locked yet.
Also fixed: crash on quitting a renderwindow when it was rendering.
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.
This commit adds a few more execution contexts for operators, given the increasing tendency for some special regiontypes to exist within areas that must have their own set of special operators.
Examples of these include the "channel" operators in the Animation Editors (i.e. those in the 'Channels' menu), and the "Fit to Preview Window" operator for the Sequencer.
Previously, operators such as these would not function when clicked on from the menus, and they would not show the hotkeys they were mapped to.
Also, fixed a few operator definitions in the Animation Editors which were missing ot->prop defines. This meant that some hotkeys (mainly selection) were shown incorrectly in the menus.
This calls a registered menu as a popup so we can reuse header menus , currently used for Node editor and Sequencer add menu (Shift+A), can be used for toolbox too.
* Move function to compute visible screen layers to BKE.
* Use this now in the depsgraph, was still using this all layers
to flush. Still missing a way to get the current scene in
background mode..
* Also two more function to not require a scene pointer anymore:
* DAG_object_update_flags is now DAG_id_update_flags.
* DAG_ids_flush_update is now available next to DAG_scene_flush_update.
* When resizing the window, the top position is now preserved,
instead of the center position.
* Fix zoom level not being preserved in various cases, when
changing both with and height. This replaces some earlier code
which did this at screen level but wasn't very reliable.
* Different tabs now each preserve their own scroll.
* When switching between tabs, it now scrolls to show as many
buttons as possible, instead of possibly showing empty space.
There is a trade-off here between doing that keeping the
buttons in the same place, no ideal solution exists I think.
* Change zooming in/out to be symmetric, for example doing
numpad + then - did not give the original zoom level back.
* Added some calls to avoid hanging tooltips when manipulating
the view.
Internals:
* Added V2D_KEEPOFS_X and V2D_KEEPOFS_Y to keep the top/bottom
rather than the center.
* Renamed V2D_KEEPZOOM to V2D_LIMITZOOM (seems more appropriate),
and make V2D_KEEPZOOM preserve the zoom level.
- running a script from a file now uses the PyRun_File(FILE *, ...) rather then PyRun_String("exec(open(r'/somepath.py').read())"...), aparently FILE struct on windows could not ensured to be the same between blender and python, since we use our own python on windows now it should be ok.
- generating docs works again (operator update for py style syntax broke them)
- python operator doc strings was being overwritten
- added rna property attribute "default" to get the default value of a property, not working on arrays currently because variable length arrays are not supported.
* ID blocks can now get RNA properties defined from python, e.g.:
bpy.types.Scene.BoolProperty(..)
* RNA structs/functions/properties can now get pointers duplicated
(mostly strings), since we can't point to some static string then.
* Added ExtensionRNA struct to add into *Type structs for subclassing,
is a bit more compact than defining the 4 variables each time.
Only disadvantage is it requires including RNA in more places.
More toolbar functionality for workflow review.
- Split the region in two parts, bottom has the Tool Properties, the
top part shows 2 panels, one for python defined tools, other for a
"tool shelf" which (later) will get saved in files.
- Added a full context driven framework for this toolbar, showing
the tools depending on 3D window 'mode'. Both python defined tools
as the shelf respect this. So - for example - you will see different
tools in editmode mesh, as in vertex paint mode, etc.
- First template for the python tools will be committed after this commit;
it has placeholder tools to just show/test functioning.
NOTE: if you had saved a layout that shows tools region, open/close it
once to get the new region created for properties.
TODO:
- Moving paint properties to tool settings
- Test a layout with horizontal toolbar (without properties)
- Bring back floating panels, and put tool-properties here. (as option)
* Headers and menus can now be created in python.
* Replaced the uiMenuItem functions to create menus with equivalent
uiItem functions using a layout, removing duplicated code.
* More uiItem functions are now exposed to python.
* The text editor header, panels and one of its menus are now created
in space_text.py.
* Buttons window data context icon new changes depending on active
object.
Issues
* Icons are not wrapped yet, hardcoded ints at the moment.
* The ID browse template is unfinished.
The Python API to define Panels and Operators is based on subclassing,
this makes that system more generic, and based on RNA. Hopefully that
will make it easy to make various parts of Blender more extensible.
* The system simply uses RNA properties and functions and marks them
with REGISTER to make them part of the type registration process.
Additionally, the struct must provide a register/unregister callback
to create/free the PanelType or similar.
* From the python side there were some small changes, mainly that
registration now goes trough bpy.types.register instead of
bpy.ui.addPanel.
* Only Panels have been wrapped this way now. Check rna_ui.c to see
how this code works. There's still some rough edges and possibilities
to make it cleaner, though it works without any manual python code.
* Started some docs here:
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/RNATypeRegistration
* Also changed some RNA_property and RNA_struct functions to not
require a PointerRNA anymore, where they were not required (which
is actually the cause of most changed files).
- Register python panels
- Added a generic class checking function BPY_class_validate() for panels/operators.
- No button drawing yet
Brecht, Added RNA_enum_value_from_id() and RNA_enum_id_from_value() to rna_access.c to do lookups between identifiers and values of EnumPropertyItem's, Not sure if these should go here.
* Added a PanelType and HeaderType for registering panels
and headers in regions. When the region draws, it will
then automatically draw the ones that were registerd with
poll and draw callbacks.
Used for text header, properties and object buttons now.
