Method Detail

isSelected

public boolean isSelected()

Returns true if this option is currently selected.

Returns:

true if this option is currently selected

setSelected

public Page setSelected(boolean selected)

Sets the selected state of this option. This will possibly also change the selected properties of sibling option elements.

Parameters:

selected - true if this option should be selected

Returns:

the page that occupies this window after this change is made (may or may not be the same as the original page)

setSelectedFromJavaScript

public void setSelectedFromJavaScript(boolean selected)

INTERNAL API - SUBJECT TO CHANGE AT ANY TIME - USE AT YOUR OWN RISK.
Sets the selected state of this option. This will possibly also change the selected properties of sibling option elements.

Parameters:

selected - true if this option should be selected

insertBefore

public void insertBefore(DomNode newNode)

Inserts the specified node as a new child node before this node into the child relationship this node is a part of. If the specified node is this node, this method is a no-op.

Overrides:

insertBefore in class DomNode

Parameters:

newNode - the new node to insert

getEnclosingSelect

public HtmlSelect getEnclosingSelect()

Gets the enclosing select of this option.

Returns:

null if no select is found (for instance malformed HTML)

reset

public void reset()

Resets the option to its original selected state.

getSelectedAttribute

public final String getSelectedAttribute()

Returns the value of the attribute selected. Refer to the HTML 4.01 documentation for details on the use of this attribute.

Returns:

the value of the attribute selected or an empty string if that attribute isn't defined.

isDefaultSelected

public final boolean isDefaultSelected()

Returns whether this Option is selected by default. That is whether the "selected" attribute exists when the Option is constructed. This also determines the value of getSelectedAttribute() after a reset() on the form.

Returns:

whether the option is selected by default

isDisabled

public final boolean isDisabled()

Description copied from interface: DisabledElement

Returns true if the disabled attribute is set for this element.

Specified by:

isDisabled in interface DisabledElement

Returns:

true if the disabled attribute is set for this element

getDisabledAttribute

public final String getDisabledAttribute()

Returns the value of the attribute disabled. Refer to the HTML 4.01 documentation for details on the use of this attribute.

Specified by:

getDisabledAttribute in interface DisabledElement

Returns:

the value of the attribute disabled or an empty string if that attribute isn't defined

getLabelAttribute

public final String getLabelAttribute()

Returns the value of the attribute label. Refer to the HTML 4.01 documentation for details on the use of this attribute.

Returns:

the value of the attribute label or an empty string if that attribute isn't defined

Sets the value of the attribute label. Refer to the HTML 4.01 documentation for details on the use of this attribute.

Parameters:

newLabel - the value of the attribute label

getValueAttribute

public final String getValueAttribute()

Returns the value of the attribute value. Refer to the HTML 4.01 documentation for details on the use of this attribute.

Returns:

the value of the attribute value

See Also:

initial value if value attribute is not set

setValueAttribute

public final void setValueAttribute(String newValue)

Sets the value of the attribute value. Refer to the HTML 4.01 documentation for details on the use of this attribute.

Parameters:

newValue - the value of the attribute value

doClickStateUpdate

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

Selects the option if it's not already selected. 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 occurs

isStateUpdateFirst

protected boolean isStateUpdateFirst()

Returns true if state updates should be done before onclick event handling. This method returns false by default, and is expected to be overridden to return true by derived classes like HtmlCheckBoxInput.

Overrides:

isStateUpdateFirst in class DomElement

Returns:

true if state updates should be done before onclick event handling

printOpeningTagContentAsXml

protected void printOpeningTagContentAsXml(PrintWriter printWriter)

Prints the content between "<" and ">" (or "/>") in the output of the tag name and its attributes in XML format.

Overrides:

printOpeningTagContentAsXml in class DomElement

Parameters:

printWriter - the writer to print in

setText

public void setText(String text)

Sets the text for this HtmlOption.

Parameters:

text - the text

getText

public String getText()

Gets the text.

Returns:

the text of this option.

mouseOver

public Page mouseOver(boolean shiftKey,
                      boolean ctrlKey,
                      boolean altKey,
                      int button)

Simulates moving the mouse over this element, returning the page which this element's window contains after the mouse move. The returned page may or may not be the same as the original page, depending on JavaScript event handlers, etc.

Overrides:

mouseOver in class DomElement

Parameters:

shiftKey - true if SHIFT is pressed during the mouse move

ctrlKey - true if CTRL is pressed during the mouse move

altKey - true if ALT is pressed during the mouse move
