Ancient annoying thing for zooming in 2d views: when a view was restricted to keep
aspect ratio, it only allowed vertical or horizontal MMB-drag zooms, depending
portrait or landscape size of editors. Same for trackpad and magic mouse.
Now vertical zoom drag always works for editors like buttons, nodes.
Post 2.65a issue
Now scrollbars appear/disappear correctly, a bug in checking if mouse clicks
where on panel headers popped up. That disabled using scrollers next to a
panel header.
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!
This was difficult to do because we group theme colours and display them
together in user preferences. To make the background options more
presentable and keep them grouped and separate, I needed to group the
two gradient colours somehow. I added a separate ThemeSpaceGradient RNA
struct as opposed to ThemeSpaceGeneric. This struct is the same as
ThemeSpaceGeneric but it lacks the window background option (which does
nothing now) and includes the UiGradient struct which now has both
gradient colours. I modified the clear functions to use a new high
colour from the gradient. Now all options appear grouped and any other
editor that may use a gradient for the window background may do so.
Also corrected incorrect MAIN_VERSION_ATLEAST macro, it would not detect
versions correctly
- 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 zoom (swipe + CTRL) direction was inverted compared to MMB-drag
or scrollwheel usage. In the 3D viewport it was OK, in all others not.
Now the same physical gesture maps identical to zooming everywhere. Or to
recap (with blender factory settings)
Zooming in:
- MMB-drag, move mouse towards screen
- Scroll wheel, move finger towards screen
- Magic Mouse, move finger towards screen
- Trackpad 2-finger swipe: move fingers toward screen.
To make this extra confusing: this is only consistent if you set your system
to inperpret trackpad swipes as "inverted" (pan view left = swipe to right).
This is a typical default, although Apple wants you to call this "Unnatural" :)
Next commit will be testing on laptop if all pinch gestures zoom consistent.
And following to that, a sensible user preference to map trackpad use for
Blender yourself, to invert system defaults again. :)
Blame and thanks goes to Sebastian Koenig, for his perseverance on getting this
solved :)
- 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.
from Patrick Boelens (senshi). with modifications to split it into its own function.
also added C style multi-line comment support /* ... */
I've left out the part of this patch that sets the language in the space, since I think this might be better stored in the text block.
For now it simply uses OSL syntax highlighting when the extension is '.osl'.
- UV Image editor and other 2d views didn't zoom for CTRL+swipe yet.
(2 finger trackpad, 1 finger mighty mouse)
- Switched defaults for 3D window swiping...
- default rotate view
- SHIFT for translate
- CTRL for zooms
This makes all editors use 'swipe' like 'middle mouse', and not
like scrollwheel (as in releases).
This is nice for consistancy, but it still feels a bit weird...
Of course users can config this in keymaps. We need a sensible
default though, and to make a 2D input input device behave like
middle mouse seeems more sensible than like a 1D wheel...
Proposal therefore for defaults:
- 1D scrollwheels: zoom in 3d, zoom in 2d, but scroll for list views.
- 2D trackpads: pan for all 2d views, rotate for 3D
I'll check with frequent trackpad users about this and we can freeze it
before release. Give it a try :)
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.
This two things were using the same DNA and RNA structures because
internally they're completely the same. However, that was confusing
from the interface point of view.
Now it should be much more clear what's going on there.
Icons in search menus were not drawing on the right location when UI panels were zoomed in large.
Not very common, but annoying. (DPI setting worked fine)
- use DummyRNA_NULL_items to replace empty enums.
- replace calloc with malloc in copy_dverts since its copied over after.
- add wmGesture->userdata, so operators that use gestures have somewhere to store their own data (not used yet).
- Button panel animation didn't work for 3D View properties and similar regions.
- Akey on View3d overlapping panel: was accidentally passed on as event to the main window.
Notes in code:
- This has to become a decent handler
- Actually "A" should open/close all?
Currently, Enter key does open/close too, but only on headers.
This because Enter on a button gets handled by buttons... that's
why the Akey was proposed :)
- Recoded soft shadow drawing for menus, giving better predictable results
(and round off nicer on top side, was looking bad still)
- Brought it under DPI control
- Added Theme setting to control size and strength for it.
