public InputMethodClientImpl(WebView wv,
                             WebPage webPage)

Method Detail

activateInputMethods

public void activateInputMethods(boolean doActivate)

Specified by:

activateInputMethods in interface InputMethodClient

getInputMethodState

public boolean getInputMethodState()

convertToWCInputMethodEvent

public static WCInputMethodEvent convertToWCInputMethodEvent(InputMethodEvent ie)

Converts the given InputMethodEvent to a WCInputMethodEvent.

getTextLocation

public Point2D getTextLocation(int offset)

Description copied from interface: InputMethodRequests

Gets the location of a specified offset in the current composed text, or of the selection in committed text. This information is, for example, used to position the candidate window near the composed text, or a composition window near the location where committed text will be inserted.

Specified by:

getTextLocation in interface InputMethodRequests

Parameters:

offset - the offset within the composed text, if there is composed text; null otherwise

Returns:

a point representing the screen location of the offset

getLocationOffset

public int getLocationOffset(int x,
                             int y)

Description copied from interface: InputMethodRequests

Gets the offset within the composed text for the specified absolute x and y coordinates on the screen. This information is used, for example to handle mouse clicks and the mouse cursor. The offset is relative to the composed text, so offset 0 indicates the beginning of the composed text.

Specified by:

getLocationOffset in interface InputMethodRequests

Parameters:

x - the absolute x coordinate on screen

y - the absolute y coordinate on screen

Returns:

the offset in the composed text.

cancelLatestCommittedText

public void cancelLatestCommittedText()

Description copied from interface: InputMethodRequests

Gets the latest committed text from the text editing node and removes it from the node's text body. This is used for the "Undo Commit" feature in some input methods, where the committed text reverts to its previous composed state. The composed text will be sent to the node using an InputMethodEvent.

Specified by:

cancelLatestCommittedText in interface InputMethodRequests

getSelectedText

public String getSelectedText()

Description copied from interface: InputMethodRequests

Gets the currently selected text from the text editing node. This may be used for a variety of purposes. One of them is the "Reconvert" feature in some input methods. In this case, the input method will typically send an input method event to replace the selected text with composed text. Depending on the input method's capabilities, this may be the original composed text for the selected text, the latest composed text entered anywhere in the text, or a version of the text that's converted back from the selected text.

Specified by:

getSelectedText in interface InputMethodRequests

Returns:

the latest committed text, or null when the "Undo Commit" feature is not supported

getInsertPositionOffset

public int getInsertPositionOffset()

Description copied from interface: ExtendedInputMethodRequests

Returns the offset of the insert position in the committed text contained in the text editing node.

Specified by:

getInsertPositionOffset in interface ExtendedInputMethodRequests

Returns:

the offset of the insert position

getCommittedText

public String getCommittedText(int begin,
                               int end)

Description copied from interface: ExtendedInputMethodRequests

Gets the entire text contained in the text editing node except the uncommitted text. The uncommitted text is ignored for index calculations.

Specified by:

getCommittedText in interface ExtendedInputMethodRequests

Parameters:

begin - the index of the first character

end - the index of the character following the last character

Returns:

the committed text

getCommittedTextLength

public int getCommittedTextLength()

Description copied from interface: ExtendedInputMethodRequests

Gets the length of the entire text contained in the text editing node except the uncommitted text.

Specified by:

getCommittedTextLength in interface ExtendedInputMethodRequests

Returns:

length of the text except the uncommitted text
