Examples of javax.swing.text.NavigationFilter

javax.swing.text.NavigationFilter
NavigationFilter can be used to restrict where the cursor can be positioned. When the default cursor positioning actions attempt to reposition the cursor they will call into the NavigationFilter, assuming the JTextComponent has a non-null NavigationFilter set. In this manner the NavigationFilter can effectively restrict where the cursor can be positioned. Similarly DefaultCaret will call into the NavigationFilter when the user is changing the selection to further restrict where the cursor can be positioned.
Subclasses can conditionally call into supers implementation to restrict where the cursor can be placed, or call directly into the FilterBypass. @see javax.swing.text.Caret @see javax.swing.text.DefaultCaret @see javax.swing.text.View @since 1.4
