Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
There are calls to define drag-able images, ID blocks, RNA paths,
file paths, and so on. By default you drag an icon, exceptionally
an ImBuf
- Drag items are registered centrally in the WM, it allows more drag
items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts
the mouse event to an EVT_DROP type. This event then gets the full
drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps
you can make a "drop map" this way, which become 'drop map handlers'
in the queues.
- next to that the UI kit handles some common button types (like
accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
- poll() = check if the event drag data is relevant for this box
- copy() = fill in custom properties in the dropbox to initialize
an operator
- The dropbox handler then calls its standard Operator with its
dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit
on mouse-over. In case the icon is a button or UI element too (most
cases), the drag-able feature will make the item react to
mouse-release instead of mouse-press.
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works
too. I've added code that passes on mousemoves and clicks to other
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an
Image ID... keep this in mind. Sequencer for example wants paths to
be dropped, textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're
part of the UI and editor design (= how we want an editor to work), and
not default offered configurable like keymaps.
- At the moment only one item can be dragged at a time. This is for
several reasons.... For one, Blender doesn't have a well defined
uniform way to define "what is selected" (files, outliner items, etc).
Secondly there's potential conflicts on what todo when you drop mixed
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip,
should be represented in filewindow as a single sequence anyway.
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it
could show the operator as a sort of menu, allowing arrow or scrollwheel
to choose. For time being I'd prefer to try to design a singular drop
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that
detects an object (type) under cursor, so a drag item's option can be
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled,
while WM event code tried same. Added new OPERATOR_HANDLED flag for this.
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
(for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review...
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS
into Blender window. I've noticed this code is unfinished for Macs, but
seems to be complete for Windows. Needs test... currently, an external
drop event will print in console when succesfully delivered to Blender's WM.
Made preview range be turned on/off using a proper flag instead of just relying on checking for start-frame = 0. It is no longer satisfactory to do that since we can have negative frame numbers, and also having it as a proper flag means that the range can be toggled on/off non-destructively.
When 'Only Selected' is ON, or the Active Object is in PoseMode, only the keyframes for the active Object are drawn (*).
Otherwise, the keyframes for the scene (sequence+nodes+world), and the selected Objects (including the Active Object) are drawn.
(*) I've also made some changes here to try and get only the selected bones showing here, but some further changes are still needed for that to be able to work.
---
Also, fixed bug in makesrna caused by missing newlines for error prints. This resulted in all error-output from makesrna appearing on a single line.
* Moved 'change shortcut' (previously directly RMB on menu items) to a context-menu item, and added Remove Shortcut and Add Shortcut. This is all available now in a RMB context menu for operator buttons and menu entries.
* Renamed a bunch of key maps to be consistent with UI names, and human-readable. Since these key map names are now being directly used in the UI for people to find things, they should be understandable and in plain language.
This renaming may break some older saved key map setups - though previously saved .b25.blends should convert over ok. Exported .py files may need some find/replacing - in this commit check the changes in resources.c to see what's changed.
* Made the TimeLine current frame indicator get drawn using the standard frame-indicator code. Also, it is now possible to show the frame indicator box beside the line as in the other animation editors, although this is disabled in the timeline due to the closeness of the frame number field.
* Removed some old (unnecessary) code
-> "Continue Physics" option in TimeLine, which is now obsolete with the current physics options. Feel free to restore if this is not the case.
-> Already commented out hacks to create "speed ipo" for curves. There are easy alternatives that are better integrated.
-> Unused init/exit callbacks for scrubbing time, since those were only used to set an obsolete flag for timeline drawing that is now used for the indicator.
* Switched long-keyframe optimisation code to use constants instead of some magic numbers + fancy trickery...
This contains two entries - one which calls the region flip operator, and one which calls the maxmize area operator.
Unfortunately, there seem to be some context issues which are causing the wrong region to get activated for use by the region flipping, meaning that nothing happens.
Also, fixed own typo in 3d-view header/menu code...
Keymaps are now saveable and configurable from the user preferences, note
that editing one item in a keymap means the whole keymap is now defined by
the user and will not be updated by Blender, an option for syncing might be
added later. The outliner interface is still there, but I will probably
remove it.
There's actually 3 levels now:
* Default builtin key configuration.
* Key configuration loaded from .py file, for configs like Blender 2.4x
or other 3D applications.
* Keymaps edited by the user and saved in .B.blend. These can be saved
to .py files as well to make creating distributable configurations
easier.
Also, user preferences sections were reorganized a bit, now there is:
Interface, Editing, Input, Files and System.
Implementation notes:
* wmKeyConfig was added which represents a key configuration containing
keymaps.
* wmKeymapItem was renamed to wmKeyMapItem for consistency with wmKeyMap.
* Modal maps are not wrapped yet.
* User preferences DNA file reading did not support newdataadr() yet,
added this now for reading keymaps.
* Key configuration related settings are now RNA wrapped.
* is_property_set and is_property_hidden python methods were added.
their handlers based on notifiers, which is simpler and more
reliable.
This fixes for example editmode or uv edit keymaps not working
when creating a new 3dview or image space.
Notifiers
---------
Various fixes for wrong use of notifiers, and some new notifiers
to make things a bit more clear and consistent, with two notable
changes:
* Geometry changes are now done with NC_GEOM, rather than
NC_OBJECT|ND_GEOM_, so an object does need to be available.
* Space data now use NC_SPACE|ND_SPACE_*, instead of data
notifiers or even NC_WINDOW in some cases. Note that NC_SPACE
should only be used for notifying about changes in space data,
we don't want to go back to allqueue(REDRAW..).
Depsgraph
---------
The dependency graph now has a different flush call:
DAG_object_flush_update(scene, ob, flag)
is replaced by:
DAG_id_flush_update(id, flag)
It still works basically the same, one difference is that it now
also accepts object data (e.g. Mesh), again to avoid requiring an
Object to be available. Other ID types will simply do nothing at
the moment.
Docs
----
I made some guidelines for how/when to do which kinds of updates
and notifiers. I can't specify totally exact how to make these
decisions, but these are basically the guidelines I use. So, new
and updated docs are here:
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/NotifiersUpdateshttp://wiki.blender.org/index.php/BlenderDev/Blender2.5/DataNotifiers
* Use scene->r.audio instead of scene->audio everywhere, was using both still.
* Fix time_top_left_3dwindow link error, not sure why this happens, somehow
with scons building it seems that files (like time_header.c) wich are not
called from the same .a module get stripped?
* Finally the header and menus are done via python.
* Added RNA for sync audio.
Note: This is just a basic working version in python. It needs more work and some layout changes.
Joshua: Feel free to adjust this further :)
* Move sound_init to make sure it gets called everytime user
preferences is reloaded.
* Merged sound_reinit and sound_init. One used user preferences
while the other did not, don't see the point of this, so just
made it always use user preferences now.
* Timeline header audio sync option now controls scene flag
rather than timeline flag. Since it uses the same playback
operator now, there is no distinction anymore.
* Added boolean property sync to animation play operator, to sync
with audio or not. Uses scene setting if property is not set.
* Playback stop button in info header now calls operator, so sounds
stop playing too.
* Fixed padding for Graph Editor visibility toggles
* Reverted many of the tweaks to Timeline UI for now (for the reasons outlined in earlier mail)
* NLA Editor now (mostly) uses the new channel-drawing API
-Made the 'PR' button not align itself to the start/end frame fields, as this makes for a nicer visual rounding of those two numbers.
-Made current frame indicator longer, to allow for display of higher frame numbers
-Removed the auto-keyframe dropdown menu. This exists as a preference, and doesn't need to take up space here. This is not something you're likely to change much after all.
-Made the keying sets menu stay put in the UI. It was moving about depending on what options are selected to the left of it. This sort of moving around should be avoided as much as possible.
-Swapped Add/Delete keyframe buttons. It's more intuitive to have the add key button first.
* Added some optimisations to avoid having to try evaluating some data that won't have any effect.
* Converted playback buttons in timeline header to use operators too
* New NLA Tracks/Strips are now only created if the 'layered' button (visible in the timeline header when autokeying is on, and the playback is running) is enabled. This multiple bones to be able to be animated in the same action, but done in multiple passes.
* Made Alt-A work in timeline header too.
* Buttons header: made tab buttons bigger, remove view menu,
replaced by RMB menu in main region.
* Timeline header: tweak button placement and alignment, added
a play reverse icon.
* Window type chooser menu: removed audio and scripts windows,
change console and logic icons.
* Node space: disable the channel region until it is used.
Animations can now be played back in reverse, by clicking on the reversed-playback button in the TimeLine header beside the play button (NEW ICON NEEDED HERE).
I'm not sure how well this works with sound, but from what I gather, this can be quite useful for animators to use.
This commit is quite experimental, and might have to be reverted, but in quite a few places, the cleanups from this commit were already necessary.
* I've left most of the image-handling functions alone, since I'm not sure how well they cope with negative indices.
* Start/End frames cannot be negative for now... any specific reasons why they should be negative?
* Moved proportional edit, snap, autokey mode, and a few others
from Scene to ToolSettings.
* RNA wrapped properties in ToolSettings for the UV editor:
proportional edit, snap settings, selection modes.
Animation playback back in control. And non-blocking still!
- Play follows the "Playback" options in TimeLine menu.
Only the region 'windows' are drawn, not headers, toolbars,
channel views, etc.
The option "Buttons Window" also redraws property regions.
- The Timeline header always redraws, this to denote at least
progressing frame numbers
- For now: if you choose to play 3D views, it also redraws
the TimeLine. Seems to be good convention, but probably
better to add menu option for it?
- Fun test: while playback, change Playback options, works OK!
- New: top header button shows animation play status, and allows
to stop playback
- New: Animation stop/start operator. Assigned to ALT+A. It has
no options yet; just plays active region + all 3D windows now.
Options will follow, based on reviews.
Also ESC won't work for now, just press ALT+A again.
- Fun for testers: Added "Redo Operator" Panel in view3d 'nkey' region.
It's going to be part of tools UI I know, but this will give good
tests of what goes on with operators. I had to add small fixes in
Transform for it already. :)
One important issue to note is that it lists every operator, also from
non-3D-window ops. Needs checked or classified somehow.
- Fix: removed bad 2.4x hack from how pulldown menus were defined. Made
widget code cleaner, and will show menus like SHIFT+A correct now.
More cleanup!
- removed old UI font completely, including from uiBeginBlock
- emboss hints for uiBlock only have three types now;
Regular, Pulldown, or "Nothing" (only icon/text)
- removed old font path from Userdef
- removed all old button theme hinting
- removed old "auto block" to merge buttons in groups
(was only in use for radiosity buttons)
And went over all warnings. One hooray for make giving clean output :)
Well, we need uniform definitions for warnings, so people at least fix
them... here's the real bad bugs I found:
- in mesh code, a call to editmesh mixed *em and *me
- in armature, ED_util.h was not included, so no warnings for wrong call
to ED_undo_push()
- The extern Py api .h was not included in the bpy_interface.c, showing
a several calls using different args.
Further just added the missing includes, and removed unused vars.
Various ui fixes:
- panel drawing now correctly follows scaled view
- made imagewindow buttons using TH_PANEL color back (was too dark)
- click on open/close panel was wrong
- menu items disabling now draws correct
- curve/hsv widgets didn't draw on right locations
- numsliders have nicer interior slider decoration
- new type TOGBUT to enforce old style toggle button (not new type
'option button' with checkmark
- (temp) disabled live updating while using Curve widget, was
too slow to be fun. Needs general solution :)
* Insert/Delete keyframe buttons in the TimeLine work again. These now use two new operators which only insert keyframes for the active Keying Set.
* Renamed the old insert/delete keyframe operators. These now have the "*_old" postfix on their names. What happens with these temp operators is yet to be seen.
* Added insert/delete keyframe buttons beside the operator buttons for Keying Sets in the Outliner->Datablocks view
When fully implemented, these will be the clearest demonstration of 'Everything is Animateable', as they will allow users to define an arbitary group of settings through selecting items in the Datablocks (RNA-Viewer) View of the Outliner to define custom 'sets'. Such Keying Sets are known as the 'absolute' ones, which are created for a custom purpose.
Of course, 'builtin' Keying Sets will still be provided. Such built-in ones will not work on any particular paths, but will use context info to maintain the legacy method of inserting keyframes (via IKEY menu).
Currently, KeyingSets cannot be created/edited through the UI, though the backend code is in place to do this.
* Removed Sequencer's own 'border zoom' tool. There is a generic one in View2D that should be used instead.
* Changed the hotkey for View2D's version of borderzoom to Shift-B
* Fixed a few hotkey mentions entries in old menus
* Added set start/end frame operators for TimeLine. (SKEY and EKEY)
* Fixed various issues in Graph Editor
- channels area is now drawn wide enough to show the 'protect' toggles without needing to scroll
- new Graph Editors have 'auto-snap' enabled by default
* 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.
Font object + editing back.
Was quite some work due to a myriad of globals all over!
Works nicely 100% local now.
To enable a single textedit operator, I've added a new
keymap entry KM_TEXTEDIT, which gives all keyboard events
to the handler. Also had to add a new keymap-add function
to force a keymap handler in beginning of region handlers.
In future this can be used to prioritize handlers.
Also: split off the arrow keys (frame change) to a separate
region level handler. Can be set with default flag in
regiontype->keymapflag ED_KEYMAP_FRAMES
