OO.ui.ProgressBarWidget

Extends

Constructor

new OO.ui.ProgressBarWidget([config]) #

Progress bars visually display the status of an operation, such as a download, and can be either determinate or indeterminate:

  • determinate process bars show the percent of an operation that is complete.

  • indeterminate process bars use a visual display of motion to indicate that an operation is taking place. Because the extent of an indeterminate operation is unknown, the bar does not use percentages.

The value of the progress configuration determines whether the bar is determinate or indeterminate.

Example

// Examples of determinate and indeterminate progress bars.
    const progressBar1 = new OO.ui.ProgressBarWidget( {
        progress: 33
    } );
    const progressBar2 = new OO.ui.ProgressBarWidget();

    // Create a FieldsetLayout to layout progress bars.
    const fieldset = new OO.ui.FieldsetLayout;
    fieldset.addItems( [
        new OO.ui.FieldLayout( progressBar1, {
            label: 'Determinate',
            align: 'top'
        } ),
        new OO.ui.FieldLayout( progressBar2, {
            label: 'Indeterminate',
            align: 'top'
        } )
    ] );
    $( document.body ).append( fieldset.$element );

Parameters:

Name Type Attributes Description
config Object optional

Configuration options

Properties:
Name Type Attributes Default Description
progress number | boolean optional
 false

The type of progress bar (determinate or indeterminate). To create a determinate progress bar, specify a number that reflects the initial percent complete. By default, the progress bar is indeterminate.

simulateLabelClick() #

Simulate the behavior of clicking on a label (a HTML <label> element) bound to this input. HTML only allows <label> to act on specific "labelable" elements; complex widgets might need to override this method to provide intuitive, accessible behavior.

By default, this does nothing. OO.ui.mixin.TabIndexedElement overrides it for focusable widgets. Individual widgets may override it too.

This method is called by OO.ui.LabelWidget and OO.ui.FieldLayout. It should not be called directly.

Inherited from:
Source:
Simulate the behavior of clicking on a label (a HTML <label> element) bound to this input.

Update the disabled state, in case of changes in parent widget.

The widget, for chaining

Type
OO.ui.Widget
Update the disabled state, in case of changes in parent widget.

updateThemeClasses() #

Update the theme-provided classes.

This is called in element mixins and widget classes any time state changes. Updating is debounced, minimizing overhead of changing multiple attributes and guaranteeing that theme updates do not occur within an element's constructor

Inherited from:
Source:
Update the theme-provided classes.
