panel.layout.spacer module#

Spacer components to add horizontal or vertical space to a layout.

class panel.layout.spacer.Divider(refs=None, **params)[source]#

Bases: Reactive

A Divider draws a horizontal rule (a <hr> tag in HTML) to separate multiple components in a layout. It automatically spans the full width of the container.

Reference: https://panel.holoviz.org/reference/layouts/Divider.html

Example:

>>> pn.Column(
...     '# Lorem Ipsum',
...     pn.layout.Divider(),
...     'A very long text... '
>>> )

Parameters inherited from:

panel.viewable.Layoutable: align, aspect_ratio, css_classes, design, height, min_width, min_height, max_width, max_height, margin, styles, stylesheets, tags, width, height_policy, sizing_mode, visible

panel.viewable.Viewable: loading

width_policy = Selector(constant=True, default='fit', label='Width policy', names={}, objects=['auto', 'fixed', 'fit', 'min', 'max'], readonly=True): Describes how the component should maintain its width. "auto" Use component’s preferred sizing policy. "fixed" Use exactly width pixels. Component will overflow if it can’t fit in the available horizontal space. "fit" Use component’s preferred width (if set) and allow it to fit into the available horizontal space within the minimum and maximum width bounds (if set). Component’s width neither will be aggressively minimized nor maximized. "min" Use as little horizontal space as possible, not less than the minimum width (if set). The starting point is the preferred width (if set). The width of the component may shrink or grow depending on the parent layout, aspect management and other factors. "max" Use as much horizontal space as possible, not more than the maximum width (if set). The starting point is the preferred width (if set). The width of the component may shrink or grow depending on the parent layout, aspect management and other factors.

class panel.layout.spacer.HSpacer(refs=None, **params)[source]#

Bases: Spacer

The HSpacer layout provides responsive horizontal spacing.

Using this component we can space objects equidistantly in a layout and allow the empty space to shrink when the browser is resized.

How-to: https://panel.holoviz.org/how_to/layout/spacing.html#spacer-components

Example:

>>> pn.Row(
...     pn.layout.HSpacer(), 'Item 1',
...     pn.layout.HSpacer(), 'Item 2',
...     pn.layout.HSpacer()
... )

Parameter Definitions

Parameters inherited from:

panel.viewable.Layoutable: align, aspect_ratio, css_classes, design, height, min_width, min_height, max_width, max_height, margin, styles, stylesheets, tags, width, width_policy, height_policy, visible

panel.viewable.Viewable: loading

sizing_mode = Parameter(constant=True, default='stretch_width', label='Sizing mode', readonly=True): How the component should size itself. This is a high-level setting for maintaining width and height of the component. To gain more fine grained control over sizing, use width_policy, height_policy and aspect_ratio instead (those take precedence over sizing_mode). "fixed" Component is not responsive. It will retain its original width and height regardless of any subsequent browser window resize events. "stretch_width" Component will responsively resize to stretch to the available width, without maintaining any aspect ratio. The height of the component depends on the type of the component and may be fixed or fit to component’s contents. "stretch_height" Component will responsively resize to stretch to the available height, without maintaining any aspect ratio. The width of the component depends on the type of the component and may be fixed or fit to component’s contents. "stretch_both" Component is completely responsive, independently in width and height, and will occupy all the available horizontal and vertical space, even if this changes the aspect ratio of the component. "scale_width" Component will responsively resize to stretch to the available width, while maintaining the original or provided aspect ratio. "scale_height" Component will responsively resize to stretch to the available height, while maintaining the original or provided aspect ratio. "scale_both" Component will responsively resize to both the available width and height, while maintaining the original or provided aspect ratio.

class panel.layout.spacer.Spacer(refs=None, **params)[source]#

Bases: Reactive

The Spacer layout is a very versatile component which makes it easy to put fixed or responsive spacing between objects.

Like all other components spacers support both absolute and responsive sizing modes.

How-to: https://panel.holoviz.org/how_to/layout/spacing.html#spacer-components

Example:

>>> pn.Row(
...    1, pn.Spacer(width=200),
...    2, pn.Spacer(width=100),
...    3
... )

Parameter Definitions

Parameters inherited from:

panel.viewable.Layoutable: align, aspect_ratio, css_classes, design, height, min_width, min_height, max_width, max_height, margin, styles, stylesheets, tags, width, width_policy, height_policy, sizing_mode, visible

panel.viewable.Viewable: loading

class panel.layout.spacer.VSpacer(refs=None, **params)[source]#

Bases: Spacer

The VSpacer layout provides responsive vertical spacing.

Using this component we can space objects equidistantly in a layout and allow the empty space to shrink when the browser is resized.

Reference: https://panel.holoviz.org/how_to/layout/spacing.html#spacer-components

Example:

>>> pn.Column(
...     pn.layout.VSpacer(), 'Item 1',
...     pn.layout.VSpacer(), 'Item 2',
...     pn.layout.VSpacer()
... )
