Arguments

app

A ShinyDriver object.

A Widget object.

name

Name of a Shiny widget.

iotype

Character scalar, whether the widget is ‘input’ or ‘output’. The default ‘auto’ value works well, provided that widgets have unique names. (Shiny allows an input and an output widget with the same name.)

value

Value to set for the widget. Its interpretation depends on the type of the widget, see details below.

keys

Keys to send to the widget. See the sendKeys method of the Element class in the webdriver package.

Details

A Widget object represents a Shiny input or output widget. app$findWidget creates a widget object from a ShinyDriver object.

w$getName() returns the name of the widget.

w$getElement() returns an HTML element. This is an Element object from the webdriver package.

w$getType() returns the type of the widget, possible values are textInput, selectInput, etc.

w$getIoType() returns ‘input’ or ‘output’, whether the widget is an input or output widget.

w$isInput() returns TRUE for input widgets, FALSE otherwise.

w$isOutput() returns TRUE for output widgets, FALSE otherwise.

w$getValue() returns the value of the widget. The exact type returned depends on the type of the widget. TODO: list widgets and their return types.

w$setValue() sets the value of the widget, through the web browser. Different widget types expect different different value arguments. TODO: list widgets and types.

w$sendKeys sends the specified keys to the HTML element of the widget.

w$listTabs lists the tab names of a tabsetPanel widget. It fails for other types of widgets.
