- Theme color for the brush popup was not correctly coded. Now it follows menu item
style correctly, which also allows all the themes we have to give readable text.
- RMB cancel also added for slider buttons and the color picker.
In text editor, the CTRL+F find now opens property region (or keeps it) and
activates the search button for input.
That's already nice! But next step should be to do a search on exit of
the button (or while typing). That's stuff I need Campbell to help with though.
Notes:
- Probably Py api for property buttons could get an "operator=" arg?
- The warning menu "not found" should go away
- I also suggest to make "wrap" search default for new editors
PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements.
=== Dynamic node type registration ===
Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes.
Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2].
=== Node group improvements ===
Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3].
The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel. Further details such as the socket name can also be changed there.

Curves widget error: after deleting a point, and click to add a new point, on dragging
it the point flipped up 20 pixels. Was caused by changed layout and region view matrix.
Solved by storing actual mousecoords instead of mapped ones.
Alt+Mouse Wheel events depended on the button under the mouse being active, else it would change the current frame.
Button re-activation wasn't 100% reliable since it depends on fake mousemove events.
Now keep button active when its executed if the mouse stays over it.
Dragging on toggle buttons can now be used to press multiple buttons at once, especially useful for layer and outliner buttons.
notes:
- automatically enabled for all toggle buttons
(may change this if it becomes a problem).
- only buttons of the same type are pressed
(helps avoid annoyances eg; dragging past layer buttons onto other 3d header buttons and pressing by accident).
- automatic axis locking - dragging will lock to X/Y depending on the initial drag direction,
makes swipe motions work better, especially with the outliner.
implementation details:
- may re-implement as a region handler (currently its a modal operator).
- checking buttons in-between cursor motion events could be more efficient (but currently works ok).
- button execution needs to be improved
(currently executing a button thats not under the mouse needed a workaround for passing uiHandleButtonData),
requires further changes to UI code, will do next.
As per discussion and analysis of all trackpad usage, we now
follow this convention:
- Blender follows system setting for trackpad direction preference.
- If you set your system to "natural" scroll, we need to invert a couple
of cases in Blender we do "natural" already. Like:
- view rotate (the inversed option just never feels ok)
- scroll active items in list or pulldown menu (up/down is absolute)
- ALT+scroll values in buttons (up/down is absolute)
The new User Preference setting "Trackpad Natural" handles this.
For 2.66 we only have trackpad handling for OS X... so this isn't
affecting trackpad usage in Windows and Linux, which stick to be mapped
to Scroll Wheel still.
(Note: viewrotate now is "natural" always, changing how it worked in the
past weeks).
if you moved your mouse fast over a button the event would get converted to a wheel, even if the input event wasnt a MOUSEPAN event.
When Alt was held this was noticable because Alt+Wheel changes button values.
added an assert to avoid this happening again.
53132 which changed the RNA index to -1 for these. Also made it so that these
buttons no longer display "Insert Single Keyframe" and only "Insert Keyframe"
as you can't edit individual components here so it's only confusing.
previous commit (54102) actually reintroduces an old bug where Blender sigfaults when
the sensor and controllers are not from the active object.
The real fix for report #33746 is to clear the "object" property after the operator ran.
I'm not sure why when I call the operator from command line the property is cleared, but not
when I called it from C. Either way all should be working now.
Blender's data link button (typically with menu and searching options)
now has a X icon to clear its contents.
Before you had to click, delete text, enter.
For example:
- Object Parent
- Modifier objects or vertexgroups
This fix saves each user 100 clicks per day, with 100k users
that's 3 billion clicks per year!
- Old issue: on scrolling button views, tooltips could open or stayed open.
- New fix: alt+swipe now changes button values again
- Removed test print, from WIP code project.
- Trackpad swipes now behave same as scrollwheel for listview scrolls
(disabling 2d view scroll when mouse over)
- Added back 2.4 debug print for glGetError()
Only useful for developers - to check what goes on when ogl messes up.
- Made more clear print for read factory default. It's not error :)
When trackpad swipes don't convert to ScrollWheel steps anymore, several hardcoded
wheel events need to support swipe too.
This adds swipe support to:
- Menu item scroll
- Search item scroll
- ALT + number/slider/swatch values
The amount of old style scroll "clicks" is calculated based on how trackad is
being mapped to move a mouse pointer. Move it one widget unit = 1 click.
The swatch option applies trackpad swipe motion in analog way.
It introduces a new (py-extendable and registrable) RNA type, UIList (roughly similar to Panel one), which currently contains only "standard" list's scroll pos and size (but may be expended to include e.g. some filtering data, etc.). This now makes lists completely independent from Panels!
This UIList has a draw_item callback which allows to customize items' drawing from python, that all addons can now use. Incidentally, this also greatly simplifies the C code of this widget, as we do not code any "special case" here anymore!
To make all this work, other changes were also necessary:
* Now all buttons (uiBut struct) have a 'custom_data' void pointer, used currently to store the uiList struct associated with a given uiLayoutListBox.
* DynamicPaintSurface now exposes a new bool, use_color_preview (readonly), saying whether that surface has some 3D view preview data or not.
* UILayout class has now four new (static) functions, to get the actual icon of any RNA object (important e.g. with materials or textures), and to get an enum item's UI name, description and icon.
* UILayout's label() func now takes an optional 'icon_value' integer parameter, which if not zero will override the 'icon' one (mandatory to use "custom" icons as generated for material/texture/... previews).
Note: not sure whether we should add that one to all UILayout's prop funcs?
Note: will update addons using template list asap.
Now scrollbars correctly hide and show, making space for the actual contents
in a region. It solves several old hacks, and puts view2d code a bit more
back in control as well.
Implementation notes:
- The view2d mask feature is working again
- The #define V2D_SCROLL_HORIZONTAL_HIDE means: "turn on hiding".
- Code for UI_view2d_region_reinit() is enforcing better standard view settings
But... two hack/patches needed to be added:
- Region panel drawing: if after generating the button panels it appears
a scroller hides or reveils, it calls all the generating code again.
(a simple scale doesn't work due to rounding differences in layout code)
- View2d code that maps 'tot' and 'cur' rects: if this code detects that
the mask changes, it calcs the map code again.
Also a bugfix (issue in 2.65)
- The left/bottom area split widget was drawing 1 pixel too large sometimes,
leaving bad trails on moving area dividers.
