Lines Matching defs:state
28 * This base class encapsulates the behavior for tracking the state of
29 * meta keys such as SHIFT, ALT and SYM as well as the pseudo-meta state of selecting text.
31 * Key listeners that care about meta state should inherit from this class;
34 * This class provides two mechanisms for tracking meta state that can be used
39 * {@link #getMetaState(long)} operate on a meta key state bit mask.</li>
41 * {@link #getMetaState(CharSequence, int)} operate on meta key state flags stored
43 * meta key state of the text editor; they do not carry any positional information.</li>
51 * When key modifiers are toggled into a latched or locked state, the state
53 * meta state integer managed by the client. These latched or locked modifiers
56 * In other words, the {@link MetaKeyKeyListener} augments the meta state
139 * Resets all meta state to inactive.
149 * Gets the state of the meta keys.
164 * Gets the state of a particular meta key.
210 * state will be reset to unshifted (if it is not still down)
221 * keep track of any meta state in the specified text.
230 * keep track of the selecting meta state in the specified text.
246 * Call this if you are a method that ignores the locked meta state
