This is intended to provide a flexible text storage mechanism The model is defined by the Document interface. a document may be shared by multiple components). The text document model may be shared by other views which act as observers Together the objects used to represent the model, view, and controller. The text components have a model-view split. removing content with the backspace and del.inserting content into the editor for the.That resolves to the default keymap for those bindings not found in theĭifferent keymap.

Typically a look-and-feel implementation will install a different keymap That is shared by all JTextComponent instances as the default keymap. Instead of in the input method event pipeline.īy default the component will create a keymap (named DEFAULT_KEYMAP) For theseĬomponents, the committed text is converted to keyTyped key eventsĪnd processed in the key event pipeline starting at stage 3 Method handling in stage 4 provides a compatibility mode forĬomponents that do not process input method events. To maintain compatibility with applications that listen to keyĮvents but are not aware of input method events, the input accelerators, component navigation, etc.) With each stage capable of consuming the event: Keyboard event and input method events are handled in the following stages, With listeners by giving the listeners a chance to steal an event Use of keymaps instead of listeners, but maintains compatibility The AWT listener model lets applications attach event listeners toĬomponents in order to bind events to actions.
KeyTyped key events and committed text in input method events. The complete text input is the combination of the characters in Reaches the text component as committed text within an InputMethodEvent instead of as a key event. As a consequence, some key events do not reach the textĬomponent because they are handled by an input method, and some text input The framework, so it implements the preferred user interface for interacting Lets text components interact with input methods, separate softwareĬomponents that preprocess events to let users enter thousands ofĭifferent characters using keyboards with far fewer keys. Sent to the action doesn't contain the target text component as its source).
The action (In the case that the ActionEvent Most recently has or had focus and therefore is the subject of TextAction can determine which JTextComponent In order to allow keymaps to be shared across multiple text components, they Keymaps and the input method framework, while maintaining compatibility with The text components support flexible and internationalized text input, using These actionsĬan be bound to key events, fired from buttons, etc. The set of commands supported by the text component can beįound with the getActions() method. The component expresses its capabilities. Text components provide a number of commands that can be used Note: Non-editable text components also have a caret though The default caretīehavior can be changed by the tUpdatePolicy(int) method. Tries to make itself visible which may lead to scrolling Or a removal occurs before the caret position. Performed on the Event Dispatching Thread and updates it's positionĪccordingly if an insertion occurs before or at the caret position The UI will install a default caret unless a customized caretīy default the caret tracks all the document changes Interface that have been registered with the text component. Notification of changes to the caret position and the selectionĪre sent to implementations of the CaretListener The caret is a pluggable object in swing text components.
