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.
Added GHOST_TUns16 numOfAASamples parameter to GHOST_CreateWindow to specify the number of AA samples (null if no AA wanted)
Implemented it in the cascade of GHOST classes.
Full implementation currently done for OSX/Cocoa, stubs for other OSes.
Moguri : it's ready for your win32 implementation !
Note that fallback to a non AA window (if gfx card doesn't support AA) is done inside GHOST OS specific layer, so that blender windowmanager still gets its window created properly.
- last commit, missed include for rna_object_api.c & bad args to find_basis_mball
- use enum for GHOST tablet type None/Stylus/Eraser, had duplicate definition for these in C. Only tested X11, may need to cast to an int for other OS's.
Bugfix in OSX ghost!
The GHOST_TWindowState was set to 'invisble' always... which is a
state now handled correctly in Blender. It caused the window to not
refresh when resizing.
Removed AUX buffer for OSX, was taking too much OGL memory,
and since AUX was not used for other platforms, its benefits
faded away in the course of the time (it was just drawing
always).
* made win32 ghost getClientBounds so that it returns area compatible with osx getClientBounds
- if a window is non-fullscreen, substract decoration, since that'll be added by GHOST_WindowWin32()
* use SetWindowLongPtr/GetWindowLongPtr (instead of SetWindowLong) as it is compatible with 64bit windows.
- Added GHOST_kEventWindowMove event, for sending event that the
window has moved
- Fixed GHOST_GetClientBounds() for OSX (get window rect)
Todos:
- add same event for X11 and Windows
- solve why ghost doesn't call client event-proc while scaling window
(at least, not in osx)
on OSX to have slow selection and mouse response.
Code from the previous commit is still there, but the #define that
triggers it has been commented out.
- GEdon't crash when attempting to add constraint on game objects without physics controller
- GEimproved some physics -> graphics synchronization issues
- small experiment with game engine timing to smooth framerate/reduce tearing
This is 'ported' from Nicholas Bishop's sculpting GSoC tree. I'm bringing it
over now so a) it can be there for when lukep does his GHOST refactor b) it's
something that GHOST should have anyway, particularly now there's interest in
painting tools and c) it's missing support in Windows, so hopefully now some
enterprising Windows coder can add that more easily in the main bf tree.
Right now X11 and Mac OS X are supported. I added and can maintain the Mac OS X
part, but I'm not familiar with the Xinput stuff, which Nicholas wrote. Both
X11 and Mac are collecting active device and pressure, and Mac is also
collecting x and y tilt data. Up to coders how they want to use this info! :)
Although the data's coming in, I haven't actually made this do anything. I
thought it best to leave it to brecht to figure out what he wants to do with the
painting stuff, and I wonder what other interesting uses there could be for it
(proportional edit?). I'll write implementation details in a separate mail to
the committers list.
"Swaps left and right bytes of small cursors for Carbon on Intel."
This fixes garbled cursors on Intel Mac builds. Tested on my G4 too and it works fine.
those who work with visible dock where experimenting slowdown of UI when
blender window was overlapping dock.
now :
- check available space excluding dock
- create window with a 10 pixels border
- maximised mode is only 1 click away
This code is fixing only. Will review that when consensus will be found
about how we should create the window.
if video card is open GL accelerated and has 16 Mo or more
start window in maximized mode wich is a full screen mode
but keeping access to other windows and sytem menu items
older comps start as usual
well... probably OK, got it from a python mailing list.
When starting from commandline, the window doesnt pop to the front. this
was really bad for the play function in blender, which opens a new blender
thread.
solved with SetFrontProcess()
I've mailed Maarten to verify it, this commit is for test at other
OSX platforms.
- this was the baddie:
setDrawingContextType(GHOST_kDrawingContextTypeNone);
it was called in the window destructor, for each window closed.
I've hacked in a temporal global var to store the mainwindow. When this
line is only called for mainwindow, it all works smoothly.
- next commit is needed too!
For some real idiot reason, osx only has the left-right arrow cursor builtin, and not an up-down arrowed one. The little hand cursor seems to be used in other apps, so let's stick with that!
