fiftyone.operators.types.FrameLoaderView

Utility for animating panel state based on the given timeline_name.

Examples:

def on_load(self, ctx):
    panel.state.plot = {
        "type": "scatter",
        "x": [1, 2, 3],
        "y": [1, 2, 3],
    }

def render(self, ctx):
    panel.obj(
        "frame_data",
        view=types.FrameLoaderView(
            on_load_range=self.on_load_range,
            target="plot.selectedpoints",
        ),
    )
    panel.plot("plot")

def load_range(self, ctx, range_to_load):
    r = ctx.params.get("range")

    chunk = {}
    for i in range(r[0], r[1]):
        rendered_frame = [i]
        chunk[f"frame_data.frames[{i}]"] = rendered_frame

    ctx.panel.set_data(chunk)
    current_field = ctx.panel.state.selected_field or "default_field"
    ctx.panel.set_state("frame_data.signature", current_field + str(r))
