Arrows-move-cursor is back!
It now works for any running modal operator that doesn't handle own
arrow keys. Might need to become more restricted though, some modal
ops don't need it. Want to investigate that still where conflicts are.
"Modal cursors" now remain visible, until reset. These cursors
were reset already on edges. Example: 3d view toolbar, grease
pencil. Do note, only use WM_cursor_modal() on real modal tools,
and restore it at end.
- OpenGL still render failed when output format was set to Movie.
Now it just doesn't save a file and renders anyway.
- Bone heat weight was missing 'wait cursor'.
- Waitcursor for Mac Cocoa is back! Made all OS's use the same
nice hourglass cursor.
(Note: this violates Mac UI guidelines, we should rely on the
spinning wheel of death instead. Highly disputable that.)
The old blocking "time cursor" wasn't working anymore.
Commit 32798 overlooked that the initialization was
needed.
Now bakes show it again. Note to self: it seems to flash
slightly (like 2.49), need to check on it one day.
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.
This nice patch by Matt D. (matd in #blendercoders) adds three nice features that can be seen already in the other supported OSes:
* minimum window size: to prevent some bugs with the window manager of Blender, system windows cannot be resized smaller than the minimum size.
* Continuous Grab is finally in Windows! Default settings since alpha 0 already have the feature enabled by default, so grab a new build and enjoy :)
* GHOST support for drag and drop added. This prepares Blender for drag and drop from OS -> Blender. Currently not very useful, since wm needs to be readied for that. But it does work (do BF_GHOST_DEBUG=1 build and drag a file onto a Blender window).
Thanks Matt D.!
- when wrapping 2 mouse events were added.
- on release blender still had the last event (possibly outside the screen), where menus would fail to show. Add a mouse event by calling XWarpPointer with no movement when leaving grab.
- Use an enum for grab modes rather then boolean options.
-- GHOST_kGrabNormal: continuous grab userpref disabled
-- GHOST_kGrabWrap: wrap the mouse at the screen bounds *
-- GHOST_kGrabHide: hide the mouse while grabbing and restore the mouse where it was initially pressed *
GrabWrap is nice for transform and tools where you want some idea where the cursor is, previously I found both restoring the mouse at its original location and restoring at a clamped location was confusing with operators like transform, wrapping is not ideal but IMHO the best of a bad bunch of options.
GrabHide is for numbuts, where restoring the mouse at the initial location isnt so confusing.
- Useful for dragging buttons to the far right when theyd otherwise hit the screen edge.
- Useful for transform though probably NOT what you want when using the transform manipulator (should make an option).
- When enabled, number buttons use this as well as a different conversion of mouse movement
float numbuts: mouse 1px == 1-clickstep
int numbuts: 2px == 1 (tried 1:1 but its too jitter prone)
details...
- access as an option to GHOST_SetCursorGrab(grab, warp)
- Currently all operators that grab use this, could be made an operator flag
- only Ghost/X11 supported currently
* Image window only show game properties in game mode.
* Fix image window render info drawing wrong with alpha enabled.
* Win32 editmode cursor now uses a different one than the system
cursor, that one is barely visible, especially in the new theme
colors.
* Center text in operator header print.
* Fix sequencer unlock shortcut key.
* Fix uv layer / vertex color active render button now graying out.
* Workaround to get default zoom level 1:1 again for new buttons
(will try to fix properly later, is due to scrollbars).
* Pass on mouse location on window leave/enter too, fixing some
issues with button highlights and tooltips.
* When a modal operator runs, grab the mouse cursor so that for
example transform still works when you move your mouse outside
of the window, previously it would just stop then. This is
automatic now for all modal ops, perhaps not always needed?
* Fix for a trailing button highlight issue.
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD
Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.
* Add Area Swap: hold alt and drag with LMB from either actionzone. Release LMB on area you want to swap with. I added a matching cute cursor for this (and to make it a politically delicate issue, it's white on black).
Note, there are still some error totblocks that I haven't been able to track down properly yet, so that's still a bit WIP.
- Made WM_cursor_wait() work without context or pointers,
like old waitcursor(). Only use when operations entirely
block UI. It will set waitcursor for all open windows.
- Cleanup in mesh tools, removing old cruft, and prepare
for more goodies for shul to work on!
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.

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.
- first work on getting area/screen handling back
- added structure for where to put stuff, is still under
review, wait a bit for docs?
Campbell is working on removing every bad level include from
sources, so we can safely rebuild the src/ directory.
