Now, when trying to insert a keyframe on a driven property (using IKEY, or with
autokeying enabled), the keyframes will get created on the Driver's F-Curve
(instead of creating a new FCurve that goes into the active action, but will never
do anything). Furthermore, the x-value of the new keyframe will be the current
result of the driver expression.
Why/Motivations:
This way, it becomes easier to create corrective drivers, as you can position all
the targets the driver depends on, then adjust the driver value until it does what
you need, and then you keyframe that value to bake it into the Driver F-Curve
(in effect, "training" the computer how to behave in that case).
Usage Notes:
* In practice, that particular workflow is still quite clunky to achieve, due to some
quirks of how the driver system and the UI widgets interact. Specifically, you'll
need to disable/mute the driver before trying to edit the setting (to prevent the
driver from immediately resetting the value - before even autokey fires!). However,
if you're using the Graph Editor to preview/monitor/manage the keying process, you'll
then want to re-enable the driver before changing the targets, so that you can see
how much of a change you'll want to be applying!
* The warning about editing driver values may need to be disabled or selectively
knocked out. I had it disabled while testing this functionality, but it's actually
harmless in its current state (if just a bit annoying).
The new "default keyframe type" dropdown on the timeline header
(and also the "Keyframe Type" operator/properties in other places)
now has procedurally generated icons which reflect what that keyframe
type will look like when rendered in the Dope Sheet.
This was achieved using the ancient "VICON" (vector icon) stuff
that's lurking around in the dark parts of UI code. From memory,
the only other things that use (or used to use) this stuff included
some of the triangle icons for some dropdown buttons, or something
like that.
Notes:
* Theme colour changes are reflected immediately by these icons.
This is possible because they are all drawn procedurally
* These icons scale with the DPI setting. I manually guessed the size of
these icons. They can be adjusted further if needed.
* I've documented the steps for adding voodoo icons like this on the wiki
(http://wiki.blender.org/index.php/Dev:2.7/Source/Checklists/Vector_Icon)
* It's true that the rendering of these keyframes doesn't quite fit the rest
of the icons in the UI. However, since we're just leveraging the standard
keyframe drawing methods (to avoid discreptancies between the two), we'll
leave it as such for now. Maybe later we can consider blending in a bit of
the glossy keyframe icons in the Icon Sheet?
To make it easier for animators working in a multipass pose-to-pose workflow
when inserting breakdown keyframes and so forth, it is now possible to specify
the "type" of keyframe being created (i.e. the colour of the keyframe, when drawn
in the Dope Sheet).
Usage:
1) Choose the type of keyframe ("Keyframe", "Breakdown", "Extreme", etc.) from
the new dropdown located between the AutoKeying and KeyingSet widgets on the
timeline header.
2) Insert keyframes
3) Rejoyce that your newly created keyframes have now been coloured for you already
in the DopeSheet.
Todo:
* Look into a way of using the actual keyframe colours (from the theme) for the icons
of these types.
Only applied in a really few cases actually.
To reproduce:
* Open User Preferences *in own window*
* Search for node wrangler add-on (it's one of the few cases where this happens)
* Enable and open details
* Click on one of the menues in the add-on preferences
Actually this was reproducable in any window, user preference area just had to take up most/all of the width.
Note: I'm not totally sure if just disabling these lines is correct, but I didn't find any issues or any information why this was needed. So it seems to be redundant.
Needed to allow modal UI keymaps, but I'm sure we'll need this more often in future.
First item will be modal eyedropper keymap coming in a following commit.
With continuous grab disabled, non-linear mapping for int buttons
wasn't working usefully with small mouse movements.
Now 2x pixels motion adjusts by at least 1 w/ int buttons.
Displaying a button would clamp the value if the button was outside the range.
This could be OK in some cases,
however it's problematic with object dimensions which would re-scale objects on showing the panel.
Add `ui_but_update_edited` when its OK to modify the value.
Now a 'More' item is added to the pie when there are too many items. It opens a sub-pie that contains the remaining items.
Note that this only touches operator-enum pies (like the object mode pie is), it is not a complete support for pies with more than 8 items. For this further design and code work would be needed, but this is too urgent to wait for that.
This is a better fix for T46973, should definitely be applied for 2.77 release.
Patch D1800 by myself with some edits by @campbellbarton, thanks!
Each LINES draw call is now responsible for its own line width. No need
to set it back to its 1.0 default after every draw.
This eliminates half our calls to glLineWidth , similar to last week’s
work on glPointSize.
UI_panel_category_draw_all was setting PolygonMode to LINES before
drawing LINES.
stitch_draw was setting PolygonMode to its default FILL value — any
function that deviates from the default should’ve changed it back to
FILL.
