A ShinyDriver object.
A Widget object.
Name of a Shiny widget.
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 to set for the widget. Its interpretation depends on the type of the widget, see details below.
Keys to send to the widget. See the sendKeys
method of the Element class in the
webdriver package.
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.
