Abstract methods

def makePic: Pic

Returns a Pic that graphically represents the current state of the view’s model object. This method is automatically invoked by the view after GUI events and clock ticks. Left abstract by this class so any concrete view needs to add a custom implementation.

Returns a Pic that graphically represents the current state of the view’s model object. This method is automatically invoked by the view after GUI events and clock ticks. Left abstract by this class so any concrete view needs to add a custom implementation.

For best results, all invocations of this method on a single view object should return Pics of equal dimensions.

Attributes

def refresh(): Unit

Programmatically requests an update to the graphics of the view (even though no clock tick or triggering GUI event occurred).

Programmatically requests an update to the graphics of the view (even though no clock tick or triggering GUI event occurred).

Concrete methods

Determines if the given state is a “done state” for the view. By default, this is never the case, but that behavior can be overridden.

Determines if the given state is a “done state” for the view. By default, this is never the case, but that behavior can be overridden.

Once done, the view stops reacting to events and updating its graphics and may close its GUI window, depending on the constructor parameters of the view.

Attributes

override def isPaused: Boolean

Indicates whether the view is paused. By default, always returns false.

final def traced: Traced[String]
