Usage

The Trame Tutorial is the place to go to learn how to use the library and start building your own application.

The API Reference documentation provides API-level documentation.

The Dockview website is very well made for exploring capabilities that the library is providing.

DockView Widget

First you need to import the dockview module so you can instantiate the layout manager like illustrated below.

from trame.app import TrameApp
from trame.ui.html import DivLayout
from trame.ui.vuetify3 import SinglePageLayout
from trame.widgets import dockview, html
from trame.widgets import vtk as vtk_widgets
from trame.widgets import vuetify3 as v3

THEMES = [
    "Abyss",
    "AbyssSpaced",
    "Dark",
    "Dracula",
    "Light",
    "LightSpaced",
    "Replit",
    "VisualStudio",
]


class Demo(TrameApp):
    def __init__(self, server=None):
        super().__init__(server)
        self._panel_count = 0
        self._build_ui()

        # init vtk.js
        vtk_widgets.VtkView(trame_server=server)

    def _build_ui(self):
        with SinglePageLayout(self.server, full_height=True) as self.ui:
            with self.ui.toolbar:
                v3.VSpacer()
                v3.VSelect(
                    v_model=("theme", "Abyss"),
                    items=("themes", THEMES),
                    hide_details=True,
                    density="compact",
                    style="max-width:200px;",
                )
                v3.VBtn(icon="mdi-plus", click=self.add_panel, density="compact")

            with self.ui.content:
                with v3.VContainer(classes="pa-0 ma-0 fill-height", fluid=True):
                    dockview.DockView(
                        ctx_name="dock_view",
                        theme=("theme",),
                    )

    def add_panel(self):
        self._panel_count += 1
        panel_id = f"panel_{self._panel_count}"
        title = f"Panel {self._panel_count}"
        template_name = f"dock_{panel_id}"
        resolution_key = f"{template_name}_resolution"

        with DivLayout(self.server, template_name) as layout:
            layout.root.style = "height:100%;position:relative;"
            with vtk_widgets.VtkView() as view:
                with html.Div(
                    style="position:absolute;top:1rem;right:1rem;z-index:1;display:flex;flex-align:center;"
                ):
                    html.Input(
                        type="range",
                        v_model_number=(resolution_key, 6),
                        min=3,
                        max=60,
                        step=1,
                    )
                    html.Button(
                        "Reset",
                        style="padding:0 5px;margin:10px;background:white;",
                        click=view.reset_camera,
                    )

                with vtk_widgets.VtkGeometryRepresentation():
                    vtk_widgets.VtkAlgorithm(
                        vtk_class="vtkConeSource",
                        state=(f"{{ resolution: {resolution_key} }}",),
                    )

        self.ctx.dock_view.add_panel(panel_id, title, template_name)

    app = Demo()
    app.server.start()


if __name__ == "__main__":
    main()
