public SafariReadOnlyKeyboardHandler()

Method Detail

onDelete

protected void onDelete(Event event,
                        Element element)

Deletes a read-only element when it is the only target of the given event.

WebKit browsers don't restore the selection after an element that contained or was touched by the selection is removed. Instead of manually removing the read-only element we select it and let the browser remove it.

Overrides:

onDelete in class ReadOnlyKeyboardHandler

Parameters:

event - the native event that was fired

element - the read-only element to be deleted

See Also:

ReadOnlyKeyboardHandler.onDelete(Event, Element)

onDelete

protected void onDelete(Event event,
                        Element element,
                        Range range,
                        boolean start)

Deletes a read-only element when it is not the only target of the given event.

WebKit browsers don't restore the selection after an element that contained or was touched by the selection is removed. Instead of manually removing the read-only element we extend the given range to include the element and let the browser remove it.

Overrides:

onDelete in class ReadOnlyKeyboardHandler

Parameters:

event - the native event that was fired

element - the read-only element to be deleted

range - the range that touches the read-only element

start - true if the start point of the given range is inside the read-only element, false if the end point is inside the read-only element

See Also:

ReadOnlyKeyboardHandler.onDelete(Event, Element, Range, boolean)

moveCaretOutside

protected void moveCaretOutside(com.google.gwt.dom.client.Node node,
                                boolean before)

Places the caret outside of the specified node, either before or after.

WebKit browsers don't keep the caret where we put it (before/after the macro container) so we have to add a text node and select it to be sure the caret remains outside of the macro.

Overrides:

moveCaretOutside in class ReadOnlyKeyboardHandler

Parameters:

node - a DOM node

before - true to place the caret before the given node, false to place it after
