HeaderClickedEvent

This is emitted by the TableView when a user clicks on a column header.

Its member columnIndex has the zero-based index of the column that was clicked.

The default behavior of this event is to do nothing, so preventDefault has no effect.

class HeaderClickedEvent : Event {
enum EventString;
}

Implementations for the ReflectableProperties interface/

propagates
bool propagates()

Events should generally follow the propagation model, but there's some exceptions to that rule. If so, they should override this to return false. In that case, only bubbling event handlers on the target itself and capturing event handlers on the containing window will be called. (That is, dispatch will call sendDirectly instead of doing the normal capture -> target -> bubble process.)

cancelable
bool cancelable()

hints as to whether preventDefault will actually do anything. not entirely reliable.

Register
mixintemplate Register()

You can mix this into child class to register some boilerplate. It includes the EventString member, a constructor, and implementations of the dynamic get data interfaces.

source
Widget source;
target
alias target = source
srcElement
alias srcElement = source

This is the widget that emitted the event.

relatedTarget
Widget relatedTarget;

Note: likely to be deprecated at some point.

preventDefault
void preventDefault()

Prevents the default event handler (if there is one) from being called

stopPropagation
void stopPropagation()

Stops the event propagation immediately.

adjustScrolling
void adjustScrolling()
adjustClientCoordinates
void adjustClientCoordinates(int deltaX, int deltaY)

This is an internal implementation detail you should not use. It would be private if the language allowed it and it may be removed without notice.

sendDirectly
void sendDirectly()

this sends it only to the target. If you want propagation, use dispatch() instead.

dispatch
void dispatch()

this dispatches the element using the capture -> target -> bubble process
