Detailed Description

Property Documentation

anchorPosition : const int

This property holds the anchor position.

This property is changed when the anchor position changes.

Access functions:

int anchorPosition() const

Notifier signal:

void anchorPositionChanged()

anchorRectIntersectsClipRect : const bool

Holds true if the bounding rectangle of the selection anchor intersects the exposed input item rectangle.

Access functions:

bool anchorRectIntersectsClipRect() const

Notifier signal:

void anchorRectIntersectsClipRectChanged()

See also Qt::ImAnchorRectangle and Qt::ImInputItemClipRectangle.

anchorRectangle : const QRectF

This property holds the anchor rectangle.

This property is changed when the anchor rectangle changes.

Access functions:

QRectF anchorRectangle() const

Notifier signal:

void anchorRectangleChanged()

animating : bool

This property holds the animating status.

Use this property to set the animating status, for example during UI transitioning states.

Access functions:

bool isAnimating() const
void setAnimating(bool isAnimating)

Notifier signal:

This property is changed when the caps lock status changes.

Access functions:

bool isCapsLockActive() const

Notifier signal:

void capsLockActiveChanged()

cursorPosition : const int

This property holds the cursor position.

This property is changed when the cursor position changes.

Access functions:

int cursorPosition() const

Notifier signal:

void cursorPositionChanged()

cursorRectIntersectsClipRect : const bool

Holds true if the bounding rectangle of the input cursor intersects the exposed input item rectangle.

bool cursorRectIntersectsClipRect() const

Notifier signal:

void cursorRectIntersectsClipRectChanged()

See also Qt::ImCursorRectangle and Qt::ImInputItemClipRectangle.

cursorRectangle : const QRectF

This property holds the cursor rectangle.

This property is changed when the cursor rectangle changes.

Access functions:

QRectF cursorRectangle() const

Notifier signal:

void cursorRectangleChanged()

inputEngine : QVirtualKeyboardInputEngine* const

This property holds the input engine.

This property stores the input engine.

Access functions:

locale : const QString

This property holds the locale.

This property is changed when the input locale changes.

Access functions:

QString locale() const

Notifier signal:

void localeChanged()

preeditText : QString

This property holds the pre-edit text.

This property sets the pre-edit text.

Access functions:

QString preeditText() const
void setPreeditText(const QString &text, QList<QInputMethodEvent::Attribute> attributes = QList<QInputMethodEvent::Attribute>(), int replaceFrom = 0, int replaceLength = 0)

Notifier signal:

void preeditTextChanged()

selectedText : const QString

This property holds the selected text.

This property is changed when the selected text changes.

Access functions:

QString selectedText() const

void selectedTextChanged()

selectionControlVisible : const bool

Holds true if the selection control is currently visible.

Access functions:

bool isSelectionControlVisible() const

Notifier signal:

void selectionControlVisibleChanged()

shiftActive : const bool

This property holds the shift status.

This property is changed when the shift status changes.

Access functions:

bool isShiftActive() const

Notifier signal:

void shiftActiveChanged()

surroundingText : const QString

This property holds the surrounding text around cursor.

This property is changed when the surrounding text around the cursor changes.

Access functions:

QString surroundingText() const

Notifier signal:

void surroundingTextChanged()

uppercase : const bool

This property holds the uppercase status.

This property is true when either shiftActive or capsLockActive is true.

Access functions:

bool isUppercase() const

Notifier signal:

void uppercaseChanged()

Member Function Documentation

void QVirtualKeyboardInputContext::clear()

Clears the pre-edit text.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

void QVirtualKeyboardInputContext::commit()

Commits the current pre-edit text.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

void QVirtualKeyboardInputContext::commit(const QString &text, int replaceFrom = 0, int replaceLength = 0)

Commits the final text to the input item and optionally modifies the text relative to the start of the pre-edit text. If replaceFrom is non-zero, the text replaces the contents relative to replaceFrom with a length of replaceLength.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

void QVirtualKeyboardInputContext::sendKeyClick(int key, const QString &text, int modifiers = 0)

Sends a key click event with the given key, text and modifiers to the input item that currently has focus.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
