identifierName()

virtual QString QMacInputContext::identifierName ( )

inlinevirtual

This function must be implemented in any subclasses to return the identifier name of the input method.

Return value is the name to identify and specify input methods for the input method switching mechanism and so on. The name has to be consistent with QInputContextPlugin::keys(). The name has to consist of ASCII characters only.

There are two different names with different responsibility in the input method domain. This function returns one of them. Another name is called 'display name' that stands for the name for endusers appeared in a menu and so on.

isComposing()

bool QMacInputContext::isComposing ( ) const

virtual

This function indicates whether InputMethodStart event had been sent to the current focus widget.

It is ensured that an input context can send InputMethodCompose or InputMethodEnd event safely if this function returned true.

The state is automatically being tracked through sendEvent().

language()

QString QMacInputContext::language ( )

virtual

This function must be implemented in any subclasses to return a language code (e.

g. "zh_CN", "zh_TW", "zh_HK", "ja", "ko", ...) of the input context. If the input context can handle multiple languages, return the currently used one. The name has to be consistent with QInputContextPlugin::language().

This information will be used by language tagging feature in QInputMethodEvent. It is required to distinguish unified han characters correctly. It enables proper font and character code handling. Suppose CJK-awared multilingual web browser (that automatically modifies fonts in CJK-mixed text) and XML editor (that automatically inserts lang attr).

mouseHandler()

void QMacInputContext::mouseHandler ( int  x, QMouseEvent *  event  )

protectedvirtual

This function can be reimplemented in a subclass to handle mouse press, release, double-click, and move events within the preedit text.

You can use the function to implement mouse-oriented user interface such as text selection or popup menu for candidate selection.

The x parameter is the offset within the string that was sent with the InputMethodCompose event. The alteration boundary of x is ensured as character boundary of preedit string accurately.

The event parameter is the event that was sent to the editor widget. The event type is QEvent::MouseButtonPress, QEvent::MouseButtonRelease, QEvent::MouseButtonDblClick or QEvent::MouseMove. The event's button and state indicate the kind of operation that was performed.

Reimplemented from QInputContext.

    if (pos < 0 || pos > currentText.length())
        reset();
    // ##### handle mouse position
#else
    Q_UNUSED(pos);
    Q_UNUSED(e);
#endif
}

reset()

void QMacInputContext::reset ( )

virtual

This function can be reimplemented in a subclass to reset the state of the input method.

This function is called by several widgets to reset input state. For example, a text widget call this function before inserting a text to make widget ready to accept a text.

Default implementation is sufficient for simple input method. You can override this function to reset external input method engines in complex input method. In the case, call QInputContext::reset() to ensure proper termination of inputting.

In a reimplementation of reset(), you must not send any QInputMethodEvent containing preedit text. You can only commit string and attributes; otherwise, you risk breaking input state consistency.

setFocusWidget()

void QMacInputContext::setFocusWidget ( QWidget *  widget )

virtual

Sets the widget that has an input focus for this input context.

Warning

Ordinary input methods must not call this function directly.
