createEditor back to summary

createEditor	back to summary
protected JComponent createEditor() This method is called by installUI to get the editor component of the `JSpinner`. By default it just returns `JSpinner.getEditor()`. Subclasses can override `createEditor` to return a component that contains the spinner's editor or null, if they're going to handle adding the editor to the `JSpinner` in an `installUI` override. Typically this method would be overridden to wrap the editor with a container with a custom border, since one can't assume that the editors border can be set directly. The `replaceEditor` method is called when the spinners editor is changed with `JSpinner.setEditor`. If you've overridden this method, then you'll probably want to override `replaceEditor` as well. Returns:JComponent the JSpinners editor JComponent, spinner.getEditor() by default See Also `installUI`, `replaceEditor`, `JSpinner#getEditor`

protected JComponent createEditor()

Typically this method would be overridden to wrap the editor with a container with a custom border, since one can't assume that the editors border can be set directly.

The replaceEditor method is called when the spinners editor is changed with JSpinner.setEditor. If you've overridden this method, then you'll probably want to override replaceEditor as well.

Annotations

@SuppressWarnings:serial

A handler for spinner arrow button mouse and action events. When a left mouse pressed event occurs we look up the (enabled) spinner that's the source of the event and start the autorepeat timer. The timer fires action events until any button is released at which point the timer is stopped and the reference to the spinner cleared. The timer doesn't start until after a 300ms delay, so often the source of the initial (and final) action event is just the button logic for mouse released - which means that we're relying on the fact that our mouse listener runs after the buttons mouse listener.

Note that one instance of this handler is shared by all slider previous arrow buttons and likewise for all of the next buttons, so it doesn't have any state that persists beyond the limits of a single button pressed/released gesture.
