the Python invoke function can then edit the properties based on the event, once its finished the properties are copied back to the operator.
python exec and invoke functions can now return RUNNING_MODAL, CANCELLED, FINISHED, PASS_THROUGH flags
Still need to look into how python operators can make use of invoke/exec for a practical case. (Need to bring back the popup menu's)
* Added 'set handle-type' operator. Currently, all possible handle types are all set using a menu and HKEY. This will need to be reviewed at some point, but I think it should be easier for users to remember 1 hotkey for this, rather than 4 scattered around the place.
* Added 'set interpolation' operator. This uses the Shift-T hotkey as before (for now). As in AnimSys2, this sets per-keyframe interpolation.
* Remapped toggle frames/time-codes operator to Ctrl-T key. This may still change, but the TKEY needs to be free for transform tool here.
* After several hours of manual dragging and typing the icon file is now
enlarged and completely reorganised logically, rather than scattered
throughout. This should provide a lot more room for growth, and is a
lot easier to work with (also allowing more space for toggle buttons
that require two icon slots next to each other). The icon grid has now
25 x 24 icons - hopefully this might last us for a couple more years :)
Some of the naming of icon defines is a bit ancient and can be cleaned
up a bit further. Other devs, if when bringing spaces back, it's
finding the wrong icon, or missing a define, try and look to see if
it's already existing in the new icon file, or drop me a note and I'll
fix it up.
Note: after these changes, older custom blender 2.4 icon
files won't work and will need to be updated to the new layout.
* Enlarged the icons themselves from 15x16 pixels to 16x16 pixels (icon
designer request). This is a more standard size, and is easier to fit
stuff in proportionally.
* Added a bunch more of jendrzych's icons that weren't added previously
since there wasn't space in the icon file (including a few more
modifier icons)
* Tweaked the outliner somewhat, so that instead of just showing a
generic 'object' icon for all objects, it shows 'object type' icons,
per object type. This makes the outliner a lot more useful for browsing
at a glance - a huge row of identical 'object' icons doesn't really
give much useful information. See here:

Ported object selection tools
- (de)select all
- invert selection (ctrl-i)
- select random ( numpad *)
each selection tool is own operator , mouse selection is seperated again to own operator
select random has the hard coded fac of 50 as there is no number popup developed yet
to be ported: select by layer and select by type
Anim playback part 1 (needs more test, will do after commit)
- added the update_for_new_frame() back
- proper evaluation of time change notifier in WM level
- fixed redraw flushes for menus while animation plays.
Notifier system upgrade, based on Brecht's doc.
Implementation notes:
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/DataNotifiers#Implementation
In short: let's try to strictly communicate in a notifier what happened.
The listeners then can act themselves. It also means that a frame-changed
notifier doesn't send out redraws, the editors themselves can decide.
This means you can define an operator in python that is called from C or Python - like any other operator.
Python functions for invoke and exec can be registered with an operator name.
keywords are read from the python exec() function, then used to create operator properties. The default python values are used to set the property type and defaults.
def exec(size=2.0, text="blah"): ...
is equivalent to...
prop = RNA_def_property(ot->srna, "size", PROP_FLOAT, PROP_NONE);
RNA_def_property_float_default(prop, 2.0f);
prop = RNA_def_property(ot->srna, "size", PROP_STRING, PROP_NONE);
RNA_def_property_string_default(prop, "blah");
TODO -
* make use of events
* return OPERATOR_CANCELLED/OPERATOR_FINISHED.. etc
* add support for array args
* more testing
* Started porting back keyframe editing tools for the Action Editor/Dopesheet. Currently, only Snap (Shift-S) and Mirror (Shift-M) are functional.
* Added keyframe-editing API method for ensuring that all IPO-curves are left in a valid state after modifiying the values of their keyframes.
* Added operator-register flags for most of the operators. Only mouse-select doesn't have it for now (as there's not much useful info stored, and no exec callback).
*******
Made the framework for selection operations ( invert selection, select random) to be handled by a single operator, atm only normal/mouse selection is possible
to be ported
- invert selection
- select random
- select by layer
- select by type
* when tracking a crasher I did svn update to specific revisions, updating back and forth somehow made some of my changes disappear in bitheaven. Bringing back aspect once again (rest of todays commit will follow soon).
* Added support for using pointers + collections as operator properties,
but with the restriction that they must point to other type derived from
ID property groups. The "add" function for these properties will allocate
a new ID property group and point to that.
* Added support for arrays with type IDP_GROUP in ID properties.
* Fix bug getting/setting float array values.
Example code for collections, note the "OperatorMousePath" type is defined
in rna_wm.c and has a float[2] property named "loc".
Defining the operator property:
prop= RNA_def_property(ot->srna, "path", PROP_COLLECTION, PROP_NONE);
RNA_def_property_struct_runtime(prop, &RNA_OperatorMousePath);
Adding values:
PointerRNA itemptr;
float loc[2] = {1, 1},
RNA_collection_add(op->ptr, "path", &itemptr);
RNA_float_set_array(&itemptr, "loc", loc);
Iterating:
RNA_BEGIN(op->ptr, itemptr, "path") {
float loc[2];
RNA_float_get_array(&itemptr, "loc", loc);
printf("Location: %f %f\n", loc[0], loc[1]);
}
RNA_END;
- Added 3d cursor operator (no exec, waiting for vector property!)
- Added default editor callbacks, for the poll() function.
Example:
ot->poll= ED_operator_view3d_active;
I'll add later more, per module, such as OBJECT_active, which
can be called without WM active
Brought back 'smooth view'. Took some hours to untangle it all,
code was spread all over, instead of localized in 1 call. Tsk!
Still not perfect, but at least more in control. For the hackers;
check void smooth_view() in view3d_view.c, here all 3d view
stuff should be handled, so it can optionally use animating.
For the users: 'smooth view' now plays at a maximum of 30 hz,
and doesn't block anymore. So even slow animated views remain
responsive if you press many numpad keys.
Timers: added extra 'event type' argument to call to add a timer:
WM_event_add_window_timer(win, event_type, interval)
This way other timer systems don't generate overhead on the queues.
(button timers were creating unused animation-playback operators)
* API and usage is basically the same still.
* Panels were moved to region level. I first thought of keeping them at area
level, but having them at region level it's simpler to handle events and do
drawing, and also to integrate with view2d. They can still become area level
overlapping regions, if we make a floating (or docked) region that can
contain panels.
* Added back a few panels from the scene buttons for testing.
Issues still:
* The view2d handling and alignment refresh of panels is not correct yet in the
buttons window.
* I did not yet bring back the block handlers system. It was basically a system
that stored which panel was open and where the events for that panel would go.
Just a few functions, but not sure how it fits in 2.5.
* There was a case where dragging panels would not properly remove the window
level handler, but could not redo anymore even though I don't think I fixed
it.
* Some text in the panels goes past the end of the button, that is due to the
checkmark button drawing, not related to this commit.
Other UI code changes:
* Renamed interface.h to interface_intern.h for consistency.
* Fixed some issues with freeing of blocks when they changed due to context.
* uiDrawBlock now takes a context pointer (mostly for block drawextra).
Operator calls: extended WM_operator_name_call() with options whether to
call the exec() (operate immediate) or invoke() (check user input) entry.
This will allow python to use it more efficiently, but also solves the
dreaded pulldown case that showed another menu for confirmation.
New names to learn: :)
WM_OP_EXEC_DEFAULT
WM_OP_INVOKE_DEFAULT
on todo still: allow hotkey definitions to do same.
User Notes (for using tools whose behaviour has changed):
* Mouse Selection Tools:
1) Click on keyframe to modify its selection. Holding the 'Shift' modifier when doing so, will result in keyframe selection being toggled instead of replacing existing selections.
2) Click on either side of the current frame indicator while holding the 'Alt' modifier. This will select only all the keyframes on the relevant side of the current frame indicator.
3) Click on a keyframe while holding the 'Ctrl' modifier. This will select all the keyframes that fall on that frame.
* Borderselect Tools
1) BKEY selects all the keyframes within the specified range (as per normal)
2) ALT-BKEY will select either all the keyframes in the frame-range specified or the channel range specified, depending on which axis of the select region was larger. This method is prejudiced towards frame-range selection.
Code Notes:
* Finished porting over all of the remaining keyframe selection tools, and recoded the ported ones to make them easier to use (after running into some technical limitations)
* Simplified the way to check if 'animation context' is valid by moving a necessary check into that function.
* Refactored internal keyframe-looping tools to reduce the amount of code needed per tool to edit keyframes, removing a lot of the unnecessary bulk. Now, the ipo/icu_keys_bezier_loop functions recieve a few more arguments (1st arg is pointer to generic customdata, and another defines a validation callback which makes it easier to reuse some of the select callbacks).
* Added 'totrect' adjustment for number of channels being shown in Action Editor, so that scrolling will be limited to where there is data (and also so that scroller displays more relevant context info).
For this to work, filtering channels now returns the number of channels extracted. This may come into use for other tools if there's such a need.
* I still need to port over some code for markers, which is required for some of the tools which use them. For now, those tools do nothing.
* Grease-Pencil editing mode in Action Editor is currently non-functional (code is commented out due to missing dependencies). This is currently pending the re-implementation of Grease Pencil in 2.5
* WM_operator_pystring to print the python func+args for an operator
* call WM_operator_print(op) in wm_operator_invoke(), simple echo mode should be moved later.
