Constructor Detail

DefaultInputHandler

public DefaultInputHandler(View view,
                           @Nonnull
                           java.util.Hashtable bindings)

Creates a new input handler with no key bindings defined.

Parameters:

view - The view

bindings - An explicitly-specified set of key bindings, must not be null.

Since:

jEdit 4.3pre1

DefaultInputHandler

public DefaultInputHandler(View view)

Creates a new input handler with no key bindings defined.

Parameters:

view - The view

DefaultInputHandler

public DefaultInputHandler(View view,
                           DefaultInputHandler copy)

Creates a new input handler with the same set of key bindings as the one specified. Note that both input handlers share a pointer to exactly the same key binding table; so adding a key binding in one will also add it to the other.

Parameters:

copy - The input handler to copy key bindings from

view - The view

Method Detail

isPrefixActive

public boolean isPrefixActive()

Returns if a prefix key has been pressed.

Overrides:

isPrefixActive in class AbstractInputHandler<EditAction>

setCurrentBindings

public void setCurrentBindings(java.util.Hashtable bindings)

Overrides:

setCurrentBindings in class AbstractInputHandler<EditAction>

handleKey

public boolean handleKey(KeyEventTranslator.Key keyStroke,
                         boolean dryRun)

Handles the given keystroke.

Specified by:

handleKey in class AbstractInputHandler<EditAction>

Parameters:

keyStroke - The key stroke

dryRun - only calculate the return value, do not have any other effect

Returns:

true if the input could be handled.

Since:

jEdit 4.2pre5

getSymbolicModifierName

public static char getSymbolicModifierName(int mod)

Returns a the symbolic modifier name for the specified Java modifier flag.
