Method Detail

getSubmitNameValuePairs

public NameValuePair[] getSubmitNameValuePairs()

Returns an array of NameValuePairs that are the values that will be sent back to the server whenever this element's containing form is submitted.

THIS METHOD IS INTENDED FOR THE USE OF THE FRAMEWORK ONLY AND SHOULD NOT BE USED BY CONSUMERS OF HTMLUNIT. USE AT YOUR OWN RISK.

Specified by:

getSubmitNameValuePairs in interface SubmittableElement

Overrides:

getSubmitNameValuePairs in class HtmlInput

Returns:

the values that will be sent back to the server whenever this element's containing form is submitted

click

public Page click()
           throws IOException

Submit the form that contains this input. Only a couple of the inputs support this method so it is made protected here. Those subclasses that wish to expose it will override and make it public.

Overrides:

click in class DomElement

Returns:

the Page that is the result of submitting this page to the server

Throws:

IOException - If an IO error occurs

doClickStateUpdate

protected boolean doClickStateUpdate(boolean shiftKey,
                                     boolean ctrlKey)
                              throws IOException

This method implements the control state update part of the click action.

The default implementation only calls doClickStateUpdate on parent's DomElement (if any). Subclasses requiring different behavior (like HtmlSubmitInput) will override this method.

Overrides:

doClickStateUpdate in class DomElement

Parameters:

shiftKey - true if SHIFT is pressed

ctrlKey - true if CTRL is pressed

Returns:

true if doClickFireEvent method has to be called later on (to signal, that the value was changed)

Throws:

IOException - if an IO error occurred

click

public <P extends Page> P click(int x,
                                int y)
                         throws IOException,
                                ElementNotFoundException

Simulate clicking this input with a pointing device. The x and y coordinates of the pointing device will be sent to the server.

Type Parameters:

P - the page type

Parameters:

x - the x coordinate of the pointing device at the time of clicking

y - the y coordinate of the pointing device at the time of clicking

Returns:

the page that is loaded after the click has taken place

Throws:

IOException - If an IO error occurs

ElementNotFoundException - If a particular XML element could not be found in the DOM model

click

public <P extends Page> P click(Event event,
                                boolean shiftKey,
                                boolean ctrlKey,
                                boolean altKey,
                                boolean ignoreVisibility)
                         throws IOException

INTERNAL API - SUBJECT TO CHANGE AT ANY TIME - USE AT YOUR OWN RISK.
Simulates clicking on this element, returning the page in the window that has the focus after the element has been clicked. Note that the returned page may or may not be the same as the original page, depending on the type of element being clicked, the presence of JavaScript action listeners, etc.

Overrides:

click in class DomElement

Type Parameters:

P - the page type

Parameters:

event - the click event used

shiftKey - true if SHIFT is pressed during the click

ctrlKey - true if CTRL is pressed during the click

altKey - true if ALT is pressed during the click

ignoreVisibility - whether to ignore visibility or not

Returns:

the page contained in the current window as returned by WebClient.getCurrentWindow()

Throws:

IOException - if an IO error occurs

setValue

public void setValue(String newValue)

Sets the value.

Overrides:

setValue in class HtmlInput

Parameters:

newValue - the new value

setDefaultChecked

public void setDefaultChecked(boolean defaultChecked)

Sets the default checked state to use when this element gets reset, if applicable. The default implementation is empty; only checkboxes and radio buttons really care what the default checked value is.

Specified by:

setDefaultChecked in interface SubmittableElement

Parameters:

defaultChecked - the default checked state to use when this element gets reset, if applicable

See Also:

SubmittableElement.setDefaultChecked(boolean), HtmlRadioButtonInput.setDefaultChecked(boolean), HtmlCheckBoxInput.setDefaultChecked(boolean)

setDefaultValue

public void setDefaultValue(String defaultValue)

Sets the default value to use when this element gets reset, if applicable. Also sets the value to the new default value.

Specified by:

setDefaultValue in interface SubmittableElement

Overrides:

setDefaultValue in class HtmlInput

Parameters:

defaultValue - the default value to use when this element gets reset, if applicable

See Also:

SubmittableElement.setDefaultValue(String)

isRequiredSupported

protected boolean isRequiredSupported()

Returns whether this element supports the required constraint.

Overrides:

isRequiredSupported in class HtmlInput

Returns:

whether this element supports the required constraint

setSrcAttribute

public void setSrcAttribute(String src)

Sets the src attribute.

Overrides:

setSrcAttribute in class HtmlInput

Parameters:

src - the src attribute

saveAs

public void saveAs(File file)
            throws IOException

Saves this image as the specified file.

Parameters:

file - the file to save to

Throws:
