render of objects could slow things down when redrawing the view each time a new
sample is displayed.
Now it does a partial redraw of the viewport with only the render border area,
skipping OpenGL object drawing while the render is refining.
Tiny tweak.
Dragging option (cursor change) for region dividers in editors was having an
un-even sensitivity hotspot. This conflicted with header buttons for example,
where the hotspot and bottons overlapped.
Now the hotspot is around the region-edge evenly.
in user preferences in place.
New scroller code made user pref scroller jump back on activating add-ons,
because that causes a full blender system refresh.
- The main window has sliders, which was drawn behind the region
- If property region had slider too, it got even worse.
Basically the node editor is UI view, so drawing another UI on top isn't
functioning well in general.
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.
Recoded the (2.65.1 version) region scale, which happened on loading files with
different saved size windows. Also scaling window itself was affected.
Old method: scaled region widths based on area/editor scaling factors.
That was leading to too small or too large button regions easily.
New method: region width/height now are in DPI control. Much nicer!
- On changing dpi, buttons remain visually same widths.
- On changing window sizes, the button views and zooms stick to exactly same.
Caveat: people who were using Blender with 'extreme' dpi setting, might find
the layouts slightly differ. Not sure if this is worth version patching...
Todo: overlapping regions that overlap together draw badly. Fix underway.
ED_region_visible_rect(ar, rect)
Returns the visible rect inside a region, subtracting the overlapping UI regions.
Added with minimal overhead, only called once per region draw.
Also fixes the 'Auto Key' warning print in 3d window (was behind properties)
- on setting lower DPI, the regions that were scrolled down would start moving down
1 pixel on every draw. Caused by rounding error. (int + 0.1 vs int -0.1)
(Ancient bug)
- circles used in outliner - to denote selection/active - now draw bigger, and better
centered. (2.66 fix only)
With larger header sizes (via DPI setting), splitting an area horizontally (using
left-bottom corner widget, move up) stopped immediate after split, not allowing
to drag it to a position.
Culprit was code to check minimum header size, and area operator using the same
flags. Now ScrVert has two flags - one for internal use, one for the tools to set.
Overlapping regions, when you both want them on the same side they should not overlap
each other! (Try F5 on a region to flip position).
Code for subdivision is in need for some cleanup - a branching recursion is needed.
Nice formatted version (pictures soon):
http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.66/Usability
Short list of main changes:
- Transparent region option (over main region), added code to blend in/out such panels.
- Min size window now 640 x 480
- Fixed DPI for ui - lots of cleanup and changes everywhere. Icon image need correct size still, layer-in-use icon needs remake.
- Macbook retina support, use command line --no-native-pixels to disable it
- Timeline Marker label was drawing wrong
- Trackpad and magic mouse: supports zoom (hold ctrl)
- Fix for splash position: removed ghost function and made window size update after creation immediate
- Fast undo buffer save now adds UI as well. Could be checked for regular file save even...
Quit.blend and temp file saving use this now.
- Dixed filename in window on reading quit.blend or temp saves, and they now add a warning in window title: "(Recovered)"
- New Userpref option "Keep Session" - this always saves quit.blend, and loads on start.
This allows keeping UI and data without actual saves, until you actually save.
When you load startup.blend and quit, it recognises the quit.blend as a startup (no file name in header)
- Added 3D view copy/paste buffers (selected objects). Shortcuts ctrl-c, ctrl-v (OSX, cmd-c, cmd-v).
Coded partial file saving for it. Could be used for other purposes. Todo: use OS clipboards.
- User preferences (themes, keymaps, user settings) now can be saved as a separate file.
Old option is called "Save Startup File" the new one "Save User Settings".
To visualise this difference, the 'save startup file' button has been removed from user preferences window. That option is available as CTRL+U and in File menu still.
- OSX: fixed bug that stopped giving mouse events outside window.
This also fixes "Continuous Grab" for OSX. (error since 2009)
"Area prev space" was setting areas to "Info" - in case no previous editor
could be found. That goes wrong for cases like:
- goto composite screen
- make image editor full
- render
- esc
Ancient 2.5 UI issue:
The button views in Property Editor have an internal storage, to ensure the view
on the buttons stays same when you switch contextes or select objects.
Bug was that - in case buttons were all scrolled invisible - sometimes no slider
was drawn to indicate that.
Discussion on whether this is a good feature or not: the only improvement would
be to store such settings even per object... but that's a feature creep I think.
When I added DPI support in the UI, I added code that refreshes views for 2d
regions. These refreshes also happened on screen switches or file select, causing
header views (horizontal scrolled) to clear.
Now the code less intrusive, changing header views in fewer cases.
This is a patch provided by Anthony Edlin. Thanks dude!
