Meaning of 'Draw Action'

[HoangDuyTran]

There listed in the rna_userdef.c this section of code:

prop = RNA_def_property(srna, “draw_action”, PROP_FLOAT, PROP_COLOR_GAMMA);

  RNA_def_property_float_sdna(prop, NULL, "bone_pose");
  RNA_def_property_array(prop, 3);
  RNA_def_property_ui_text(prop, "Draw Action", "");
  RNA_def_property_update(prop, 0, "rna_userdef_theme_update");

and this ‘Draw Action’ can be seen in the ‘Themes → Video Sequencer’

I have been playing with video sequencer for a while, importing a sequence of images, doing some basic visual transforms, and even adding a sequence.0001 from an animation sequence of a crankshaft, using bones, through a camera as well, I could not locate this ‘Draw Action’ and where this colour could be used. This is the file I’m using:

20230420_vse_effect_strip_transform_keying_scene_0001_crankshaft_anim_0002.blend (3.3 MB)

Could someone familiar of what it is tell me what is is applying to, please? The reason I’m asking is because I don’t know if the developer meant to say

- ‘Draw(ing) Action’

or the

‘Action of Drawing’.

I’m translating the Interface into Vietnamese and obviously the two meant different things.

Draw over a timeline region in respect to its frame numbers

Hi all, Using the following snippet I can attach a bgl draw handler to the timeline to draw over it, but I have only been able to get this to work using the POST_PIXEL callback. I was wondering if there is something like a POST_VIEW context for this callback as well, in which coordinates would relate to frame numbers? Alternatively is there another way of relating the pixel coordinates to actual frame numbers, eg by somehow detecting the amount of zoom and pan in the timeline? Thanks! i…

Thank you for answering, but this change has been done over 14 years ago, as reported by git history:

and it should be related to ‘bone_pose’ as well. This ‘bone_pose’ really puzzled me as I don’t see any relation, even that far back. I was back to use version 2.78c yesterday and could not locate anything relating either.
