Class: ProgressBarWidget

.ui.ProgressBarWidget(configopt)

new ProgressBarWidget(configopt)

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.

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.

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

    // Create a FieldsetLayout to layout progress bars
    var 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'})
    ] );
    $( 'body' ).append( fieldset.$element );

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.
