eg, layout.operator_context = 'INVOKE_REGION_WIN'
Needed to set the context that menu item operators are executed in.
fixed missing NULL check with anim system debug printing.
Preview renders:
- Added proper button type (BUT_EXTRA) for preview buttons, to
handle drawing better. It now first draws an alpha mask, to
ensure the preview is correctly fitting inside the widget style.
It then draws the outline.
- Added protection for executing preview renders while regular
rendering, that's not going to work...
Example sequencer menu
self.layout.column()
self.layout.item_enumO("SEQUENCER_OT_effect_strip_add", property='type', value='ADD', text="Effect Strip (Add)")
* layout.split() now takes a percentage argument to control
the split position.
* ID template now works for more than just the Text ID type,
includes and icon, and some other fixes.
Nice goodie: Preview renders!
- Added new preview.blend, allowing super wide cinemascope previews
- Draws nicely blended inside widget type, rounded corners
- Preview now renders using all available cpus/cores.
- Uses - hopefully rock stable - method, which doesn't copy or
allocate anything for previews, but just uses render API calls.
- Multiple previews are possible! But, added provision in Jobs
manager to only render one preview job at a time. If you start
more preview jobs, they're suspended until it's their turn.
Bugfix: new buttons context code crashed when going full-window.
Tweaks are still needed for notifiers. I have to figure out still
how to retrieve SpaceButs button view types...
Search menu:
- Made nicer drawing for popup version of search. It now uses
entire backdrop like pulldowns.
Search boxes for text buttons will use different style still;
if we use this option all over it shouldn't look too intrusive.
- Search menu allows scroll, to view all items. It doesn't cycle
anymore.
- Click outside search menu now cancels
- If a match is in search button, it highlights it. This also
allows ALT+CTRL+F - Enter to redo last op.
- Search popup draws higher when no no space below. No order
flipping!
In this commit, I've introduced the mechanism by which actions already referenced by strips used in the NLA can be edited (or 'tweaked'). To use, simply select a strip you wish to edit, and hit that TAB key to start tweaking that strip's action, and hit TAB again once you're done.
What happens when you enter 'tweak mode':
1) The action of the active strip temporarily becomes the 'active action' of the AnimData block. You are now able to edit this in one of the Animation Editors (DopeSheet/Action, Graph Editors) as per normal (i.e. sliding keyframes around, inserting keyframes, etc.). The 'action-line' will therefore get drawn immediately above the active track containing the active strip, so that it's clear that that's what we're editing.
2) All the NLA-tracks (and all the strips within them) that occur after the track that the active strip lived in get disabled while you're in tweakmode. This is equivalent to travelling back to an earlier state in a construction history stack.
3) The active NLA track also gets disabled while in tweakmode, since it would otherwise interfere with the correct functioning of the tweaking for the action of interest.
4) The 'real' active action (i.e. the one displaced by the active strip's action) gets put into temp storage, and will be restored after you exit tweakmode.
5) Any strips which also reference the action being tweaked will get highlighted in red shading to indicate that you may be making some changes to the action which you don't really want to make for the other users too.
Please note though, that this is only a rough prototype of this functionality, with some niceties still to come. i.e.:
* NLA-tracks after the active track should still get drawn above the 'tweaking action line', but perhaps with different appearance?
* Various tools will still need awareness of this to prevent corrupting operations from taking place. How to proceed is still undecided...
* When exiting tweak-mode, the strip the action came from still needs some form of syncing with the modified action... there are a few tricky issues here that will need to be solved
* Evaluation code doesn't totally take this into account yet...
---
Also, fixed a number of bugs with various code (notably selection, and also a few drawing bugs)
Further work on new "text search" button.
- Now allows to browse items (mouse, arrow key)
- Assigns active value
- Uses different backdrop to distinguish from popup menus
- Cleaned API for it, so it can be used nicely generic
Also added a search menu, which shows all currently working
operators: CTRL+ALT+F. (mind the looks, it needs some tweaks!)
To make a menu activating a button I've added a new event...
could use some tweaks.
Important note: the callback to pass on "old string" for text
button (bone rename) couldn't work yet, added first code for new
callback, but has to be worked on further. When bone rename gets
added it can be tested.
* Make modifier and constraint templates use left/right alignment for
buttons in the header.
* Added mdef bind operator as an example of how to use local context
for a modifier, and add some code I forgot to commit last time to
make this system actually work.
Part one of new text button type: SEARCH_MENU
This opens a popup showing all matches for a typed string, nice
for object names, materials, operators, and so on.
Warning: Currently menu doesn't function yet! Only draws choices.
As test I've added an operator search button in top bar. It only
shows operators that can be used in this context now. Also that
is part of the WIP, tomorrow more fun :)
- Fix: text draw in fonts was slightly too low; it didn't calculate offset
correctly. Now it is aligned to have number characters in center.
- Fix: text clip was too wide, giving errors on extreme zoom in.
- Added boundbox-clipped default text drawing for view2d:
void UI_view2d_text_cache_rectf(View2D *v2d, rctf *rect, char *str)
(Note; also for previous commit, this cache immediately projects, so if
you change view2d while drawing, text is still on correct positions)
Added support for cached text drawing in View2D. Cache is needed to
prevent the viewmatrix being set/restored on each text drawing.
Adding a string:
void UI_view2d_text_cache_add(View2D *v2d, float x, float y, char *str)
Drawing:
void UI_view2d_text_cache_draw(ARegion *ar)
Nothing else needed; just make sure cache-draw is always called at end
of a view2d drawing function, to clear cache memory.
On todo for next: a version with a rectf boundary to clip text within.
* Added click-select/left-right select and deselect all/invert all selection operators. For now, these basic operators will suffice (more advanced selection operators will be coded at a later stage).
* Fixed a few bugs in DopeSheet found while coding the relevant tools for NLA.
* Added custom border-select operator for NLA channels (since the standard one assumes negative direction channel order)
* Added new API-method for NLA strips to check if the strip occurs within a given range, since this test needed to be performed in a few places...
* Tweaked the NLA Editor View2D ranges a bit to give saner default sizing. This still isn't right yet though.
* Added some properties of uiLayout that can be set. I've added
some API code for more than the two I've implementeds, so
ignore those for now.
* layout.active = False will gray out buttons inside a layout.
* layout.enabled = False will gray out and completely disable
the buttons inside a layout.
* Also some function renames.
Added a system for adding a "local" context in a UI layout.
This way you can define for example within a modifier panel
all operators to get the modifier in the context.
In the layout code:
uiLayoutSetContextPointer(layout, "modifier", &ptr)
layout.set_context_pointer("modifier", md)
In the operator:
ptr = CTX_data_pointer_get(C, "modifier")
md = context.modifier
BMO_ITER macros to make defining iterator
loops easier. Moved some files around.
And also made the editmesh conversion functions
tesselate ngons to triangle fans, since it's
more stable for conversion, and editmeshes are
never displayed to the user anyway. And ported
akey to bmesh.
Next up I plan on adding face iterators to DerivedMesh,
since that's the last major chunk of major refactoring
left, I think, except perhaps the uv editor (at the
moment it's probably close to working, but it's still
converting to editmeshes for everything, which is very
bad).
* Added Constraints template and Add Constraint operator.
* Added toggle=True/False parameter to uiItemR, to get a
toggle button (actual button) rather than an "option"
button (checkbox)
* Added OPTION/OPTIONN button type, to distinguish with
TOG/TOGN.
RNA:
* Make all modifier pointers editable, including correct updates.
* Added notifiers and updates to constraints.
* Fix a stack corruption, pointed out by Andrea, and potentially
causing crashes.
First version of region-scaling. WIP commit, so bear with me a while!
- All fixed sized regions have a small 'drag' widget, on the left or top.
(not yet for free-sized regions, like 4-split).
- Mouse-over on widget changes cursor and allows drag.
- Click on widget hides/reveals.
- Fun for test; 3d view header, if high enough, draws more rows of
buttons when width is too small.
The WIP stuff;
- It doesn't save yet in files, using the "minsize" variable of region
definitions, also means other similar areas show same sizes now.
- Definitions for pref size, min/max will be added.
- Properties panel in Fcurve window draws widget on wrong place when
hidden (subdiv system needs tweak)
- Widgets don't draw perfect yet, also needs further tweaks.
But, in general it's quite fun and usable. :) Many variatians are possible,
like for real tabs, or little icons, or just click-drag on edge.
The reason to first try the widget/tab variation:
- it re-uses the "Area Action Zone" code, widgets for layouting Screens
- it's visible, hotkey-only options for screen layouts are not preferred.
- distinguish clearly area-edges from region-edges this way. Having the
cursor change shape on every edge (and block input) is probably annoying
too... but that can be tested.
Later more!
This includes a bunch of new object primitive icons
which would be great to get into the 'add object' menus,
they're not there yet. The specific lamp data type icons
are now used in the outliner though, which is very helpful.
- Added new popup menu type, which can be used to pass on a
running operator too. Needed it for debug menu, allowing to
set variables outside of operator "first do then tweak" system. :)
void uiPupBlockOperator()
Don't forget to tell invoke() return that operator now runs modal!
- Test menu: alt+ctrl+d gives the G.rt debug value.
Values of 0-16 now can be used to shrink areas, stuff like this
then happens (rt==4):
http://download.blender.org/institute/rt5.jpg
Was looking at ways to visually distinguish areas and regions
better. Yes I know, cute rounded corners, etc. Just testing!
* template_modifier creates the modifier box, and returns a layout
to put the buttons in.
* Only the armature modifier is now done with python code, all other
modifiers use C code. To convert a modifier to python, remove the
corresponding C code and create a function in DATA_PT_modifiers.
* Some modifiers still require some RNA work to get it working well,
especially to make pointers editable. Mostly that is a matter of
defining an own _set callback and put some of the modifier C code
into it.
* Still various buttons that don't work, like for hooks or mesh
deform binding.
* Fix for crashing decimate modifier (still disabled).
* Removed UI_BUT_NO_HILITE, HMENU.
* Make uiLayoutBox work with align.
Animation playback back in control. And non-blocking still!
- Play follows the "Playback" options in TimeLine menu.
Only the region 'windows' are drawn, not headers, toolbars,
channel views, etc.
The option "Buttons Window" also redraws property regions.
- The Timeline header always redraws, this to denote at least
progressing frame numbers
- For now: if you choose to play 3D views, it also redraws
the TimeLine. Seems to be good convention, but probably
better to add menu option for it?
- Fun test: while playback, change Playback options, works OK!
- New: top header button shows animation play status, and allows
to stop playback
- New: Animation stop/start operator. Assigned to ALT+A. It has
no options yet; just plays active region + all 3D windows now.
Options will follow, based on reviews.
Also ESC won't work for now, just press ALT+A again.
* Fix buttons jumping around when resizing and zoom. Part of this was
adding a tiny a 0.001f offset in UI_view2d_view_ortho, otherwise the
rounding is unpredictable (used to be 0.375f, but that was disabled).
* Fix various issues with zooming, panning panels. V2D_LOCKOFS_X/Y is
now taken into account in more places in the view2d code, to avoid
zooming into the center or panning out of the view.
* Remove "Free" align mode in buttons window (it's not really useful).
* View3D/Graph/Image editors now use the same PanelType system as the
buttons window, means some deprecated panel code could be removed.
* Some small visual tweaks for panels.
* View 2D Reset operator (Home key), to reset zoom and panning for panels.
* Added argument to set number buttons as sliders (slider=True for itemR).
* Ignore labels for button alignment (doesn't look right).
* Fix some use of context.main in py scripts, should get data from active
object instead.
* Fix autotexspace -> auto_texspace in py script.
Text drawing in 3D window fixed, using BLF default font (yes, nice AA'ed
fonts too :)
Solved it by gathering all strings that needs to be drawn for an object,
and then draw in end of object drawing, in pixelspace. Also cleaned up
some of the code for projecting 3d coords, much nicer now (mat stored in
region-view3d)
* Buttons are now created first, and after that the layout is computed.
This means the layout engine now works at button level, and makes it
easier to write templates. Otherwise you had to store all info and
create the buttons later.
* Added interface_templates.c as a separate file to put templates in.
These can contain regular buttons, and can be put in a Free layout,
which means you can specify manual coordinates, but still get nested
correct inside other layouts.
* API was changed to allow better nesting. Previously items were added
in the last added layout specifier, i.e. one level up in the layout
hierarchy. This doesn't work well in always, so now when creating things
like rows or columns it always returns a layout which you have to add
the items in. All py scripts were updated to follow this.
* Computing the layout now goes in two passes, first estimating the
required width/height of all nested layouts, and then in the second
pass using the results of that to decide on the actual locations.
* Enum and array buttons now follow the direction of the layout, i.e.
they are vertical or horizontal depending if they are in a column or row.
* Color properties now get a color picker, and only get the additional
RGB sliders with Expand=True.
* File/directory string properties now get a button next to them for
opening the file browse, though this is not implemented yet.
* Layout items can now be aligned, set align=True when creating a column,
row, etc.
* Buttons now get a minimum width of one icon (avoids squashing icon
buttons).
* Moved some more space variables into Style.
- drawing code cleanup
- use of BLF_font in own string drawing, needs to be aligned with uiStyles still.
- thumbnail scaling now done on graphics card via new glaDrawPixelsTexScaled (slightly modified glaDrawPixelsTex)
Cleanup of conventions for icon placement in menus.
Old code only allowed 1 icon per menu, forcing to pass on the sublevel
menu icon with exception handling.
Now sublevel icons are drawn automatically, allowing to add an icon
before name too. (Check shift+a menu)
