python - bpy.ops.sequencer.view_all() 轮询失败

Question

我寻求帮助，因为我真的不知道我必须为此做什么。我绞尽脑汁两天了，我不得不承认我就是不明白......

我需要一个脚本来将定序器中的 View 设置为 bpy.ops.sequencer.view_all() (或类似:bpy.ops.sequencer.view_selected())

为此，我需要覆盖上下文并告诉脚本它必须在定序器区域中运行该命令，如果没有，它将给出:

Python: Traceback (most recent call last):
  File "\Text", line 4, in <module>
  File "F:\MEDIA\GAMES\Steam\steamapps\common\Blender\3.4\scripts\modules\bpy\ops.py", line 113, in __call__
    ret = _op_call(self.idname_py(), None, kw)
RuntimeError: Operator bpy.ops.sequencer.view_all.poll() failed, context is incorrect

..当然只是设置:

bpy.context.area.ui_type = 'SEQUENCE_EDITOR'

..什么也不做 但我再次完全不知道该怎么做，任何帮助将不胜感激..

Answer 1

这是正确的上下文覆盖:

import bpy

# go through all areas until sequence editor is found
for area in bpy.context.screen.areas:
    if area.type == "SEQUENCE_EDITOR":
        override = bpy.context.copy()
        # change context to the sequencer
        override["area"] = area
        override["region"] = area.regions[-1]
        # run the command with the correct context
        with bpy.context.temp_override(**override):
            bpy.ops.sequencer.view_all()
        break
