(They are known as "internal frames" in the underlying Java windowing system that the Vision component uses). Internal frame events are fired by windows. InternalFrameActivated - fired when the window becomes the focused window internalFrameClosed - fired after the window is closed internalFrameClosing - fired just before the window is closed internalFrameDeactivated - fired when the window loses focus internalFrameOpened - fired the first time a window is opened after not being in the cache Properties in 'event' The most common event sets are as follows: Event SetsĮach component can have its own set of events, however most components share events, therefore, understanding the way one event works with one component will result in understanding how it works will all other components that have the same event. All of the events in an event set share the same properties for their event object. For example, the mouse event set includes mouseClicked, mousePressed, and mouseReleased. These are all of the event types that are fired by the various components in the Vision module.

The manual page for the event object covers this topic in more detail. getComponent("Name") finds a sibling component with a certain name. references the container that component is in. event.source references the component that fired whatever event you're responding to. When you have an event object, that object becomes your window into the entire component hierarchy. You'll need to reference various components on the window or on other windows, you'll need to reference and set properties of the component, you may even want to move components around on the screen. When you're writing component event handlers, you'll do a lot of work with components.
