public synchronized Object getInputMethodControlObject() Overrides java.awt.im.InputContext.getInputMethodControlObject. Doc from java.awt.im.InputContext.getInputMethodControlObject. Returns a control object from the current input method, or null. A control object provides methods that control the behavior of the input method or obtain information from the input method. The type of the object is an input method specific class. Clients have to compare the result against known input method control object classes and cast to the appropriate class to invoke the methods provided.

getLocale back to summary

public Locale getLocale()

Overrides java.awt.im.InputContext.getLocale.

Doc from java.awt.im.InputContext.getLocale.

Returns the current locale of the current input method or keyboard layout. Returns null if the input context does not have a current input method or keyboard layout or if the current input method's java.awt.im.spi.InputMethod#getLocale() method returns null.

Not all host operating systems provide API to determine the locale of the currently selected native input method or keyboard layout. For host operating systems that don't provide such API, getLocale assumes that the current locale of all native input methods or keyboard layouts provided by the host operating system is the system's default locale.

Returns:Locale: the current locale of the current input method or keyboard layout
See Also: java.awt.im.InputContext#getLocale

isCompositionEnabled back to summary

public boolean isCompositionEnabled()

Overrides java.awt.im.InputContext.isCompositionEnabled.

Doc from java.awt.im.InputContext.isCompositionEnabled.

Determines whether the current input method is enabled for composition. An input method that is enabled for composition interprets incoming events for both composition and control purposes, while a disabled input method does not interpret events for composition.

Returns:boolean

true if the current input method is enabled for composition; false otherwise

Exceptions

reconvert back to summary

public synchronized void reconvert()

Overrides java.awt.im.InputContext.reconvert.

Doc from java.awt.im.InputContext.reconvert.

Asks the current input method to reconvert text from the current client component. The input method obtains the text to be reconverted from the client component using the InputMethodRequests.getSelectedText method. The other InputMethodRequests methods must be prepared to deal with further information requests by the input method. The composed and/or committed text will be sent to the client component as a sequence of InputMethodEvents. If the input method cannot reconvert the given text, the text is returned as committed text in an InputMethodEvent.

Exceptions

UnsupportedOperationException:: when input method is null

private synchronized void removeClientWindowListeners()

removeNotify back to summary

public synchronized void removeNotify(Component component)

Overrides java.awt.im.InputContext.removeNotify.

Doc from java.awt.im.InputContext.removeNotify.

Notifies the input context that a client component has been removed from its containment hierarchy, or that input method support has been disabled for the component. This method is usually called from the client component's Component.removeNotify method. Potentially pending input from input methods for this component is discarded. If no input methods are available, then this method has no effect.

Parameters

component:Component: Client component

Exceptions

NullPointerException:: when the component is null.

java.awt.im.InputContext#removeNotify

selectInputMethod back to summary

public synchronized boolean selectInputMethod(Locale locale)

Overrides java.awt.im.InputContext.selectInputMethod.

Doc from java.awt.im.InputContext.selectInputMethod.

Attempts to select an input method or keyboard layout that supports the given locale, and returns a value indicating whether such an input method or keyboard layout has been successfully selected. The following steps are taken until an input method has been selected:

If the currently selected input method or keyboard layout supports the requested locale, it remains selected.
If there is no input method or keyboard layout available that supports the requested locale, the current input method or keyboard layout remains selected.
If the user has previously selected an input method or keyboard layout for the requested locale from the user interface, then the most recently selected such input method or keyboard layout is reselected.
Otherwise, an input method or keyboard layout that supports the requested locale is selected in an implementation dependent way.

Before switching away from an input method, any currently uncommitted text is committed. If no input method or keyboard layout supporting the requested locale is available, then false is returned.

Not all host operating systems provide API to determine the locale of the currently selected native input method or keyboard layout, and to select a native input method or keyboard layout by locale. For host operating systems that don't provide such API, selectInputMethod assumes that native input methods or keyboard layouts provided by the host operating system support only the system's default locale.

A text editing component may call this method, for example, when the user changes the insertion point, so that the user can immediately continue typing in the language of the surrounding text.

Parameters

locale:Locale: The desired new locale.

Returns:boolean

true if the input method or keyboard layout that's active after this call supports the desired locale.

Exceptions

NullPointerException:: when the locale is null.

setCharacterSubsets back to summary

public void setCharacterSubsets(Character.Subset[] subsets)

Overrides java.awt.im.InputContext.setCharacterSubsets.

Doc from java.awt.im.InputContext.setCharacterSubsets.

Sets the subsets of the Unicode character set that input methods of this input context should be allowed to input. Null may be passed in to indicate that all characters are allowed. The initial value is null. The setting applies to the current input method as well as input methods selected after this call is made. However, applications cannot rely on this call having the desired effect, since this setting cannot be passed on to all host input methods - applications still need to apply their own character validation. If no input methods are available, then this method has no effect.

Parameters

subsets:Character.Subset[]: The subsets of the Unicode character set from which characters may be input

setCompositionEnabled back to summary

public void setCompositionEnabled(boolean enable)

Overrides java.awt.im.InputContext.setCompositionEnabled.

Doc from java.awt.im.InputContext.setCompositionEnabled.

Enables or disables the current input method for composition, depending on the value of the parameter enable.

An input method that is enabled for composition interprets incoming events for both composition and control purposes, while a disabled input method does not interpret events for composition. Note however that events are passed on to the input method regardless whether it is enabled or not, and that an input method that is disabled for composition may still interpret events for control purposes, including to enable or disable itself for composition.

For input methods provided by host operating systems, it is not always possible to determine whether this operation is supported. For example, an input method may enable composition only for some locales, and do nothing for other locales. For such input methods, it is possible that this method does not throw UnsupportedOperationException, but also does not affect whether composition is enabled.

Parameters

enable:boolean: whether to enable the current input method for composition

Exceptions

UnsupportedOperationException:: when input method is null
