Inheritance diagram of panel.template.fast.grid

The Fast GridTemplate provides a grid layout based on React Grid Layout similar to the Panel ReactTemplate but in the Fast.design style and enabling the use of Fast components.

class panel.template.fast.grid.FastGridDarkTheme(*, fig, holomap, widgets, fps, max_frames, size, dpi, filename, info, css, widget_location)[source]

Bases: panel.template.fast.theme.FastDarkTheme

The Dark Theme of the FastGridTemplate

Parameters inherited from:

css = param.Filename(default=PosixPath(‘/home/runner/work/panel/panel/panel/template/fast/grid/dark.css’), label=’Css’, search_paths=[])

property bokeh_theme

Provide new default values for Bokeh models.

Bokeh Model properties all have some built-in default value. If a property has not been explicitly set (e.g. m.foo = 10), accessing the property will return the default value. It may be useful for users to be able to specify a different set of default values than the built-in default. The Theme class allows collections of custom default values to be easily applied to Bokeh documents.

The Theme class can be constructed either from a YAML file or from a JSON dict (but not both). Examples of both formats are shown below.

The plotting API’s defaults override some theme properties. Namely: fill_alpha, fill_color, line_alpha, line_color, text_alpha and text_color. Those properties should therefore be set explicitly when using the plotting API.

Parameters
  • filename (str, optional) – path to a YAML theme file

  • json (str, optional) – a JSON dictionary specifying theme values

Raises

ValueError – If neither filename or json is supplied.

Examples

Themes are specified by providing a top-level key attrs which has blocks for Model types to be themed. Each block has keys and values that specify the new property defaults for that type.

Take note of the fact that YAML interprets the value None as a string, which is not usually what you want. To give None as a value in YAML, use !!null. To give ‘None’ as a value in json, use null.

Here is an example theme in YAML format that sets various visual properties for all figures, grids, and titles:

attrs:
    Figure:
        background_fill_color: '#2F2F2F'
        border_fill_color: '#2F2F2F'
        outline_line_color: '#444444'
    Axis:
        axis_line_color: !!null
    Grid:
        grid_line_dash: [6, 4]
        grid_line_alpha: .3
    Title:
        text_color: "white"

Here is the same theme, in JSON format:

{
'attrs' : {
    'Figure' : {
        'background_fill_color': '#2F2F2F',
        'border_fill_color': '#2F2F2F',
        'outline_line_color': '#444444',
    },
    'Axis': {
        'axis_line_color': null,
    },
    'Grid': {
        'grid_line_dash': [6, 4]',
        'grid_line_alpha': .3,
    },
    'Title': {
        'text_color': 'white'
    }
}

select(selector=None)

Iterates over the Template and any potential children in the applying the Selector.

Parameters

selector (type or callable or None) – The selector allows selecting a subset of Viewables by declaring a type or callable function to filter by.

Returns

viewables

Return type

list(Viewable)

servable(title=None, location=True, area='main')

Serves the object if in a panel serve context and returns the Panel object to allow it to display itself in a notebook context. :param title: A string title to give the Document (if served as an app) :type title: str :param location: Whether to create a Location component to observe and

set the URL location.

Parameters

area (str) – The area of a template to add the component too. Only has an effect if pn.config.template has been set.

Returns

Return type

The Panel object itself

server_doc(doc=None, title=None, location=True)

Returns a servable bokeh Document with the panel attached

Parameters
  • doc (bokeh.Document (optional)) – The Bokeh Document to attach the panel to as a root, defaults to bokeh.io.curdoc()

  • title (str) – A string title to give the Document

  • location (boolean or panel.io.location.Location) – Whether to create a Location component to observe and set the URL location.

show(title=None, port=0, address=None, websocket_origin=None, threaded=False, verbose=True, open=True, location=True, **kwargs)

Starts a Bokeh server and displays the Viewable in a new tab.
