成员函数文档编制

void QVirtualKeyboardInputContext:: clear ()

Clears the pre-edit text.

注意： 此函数可以被援引，通过元对象系统和从 QML。见 Q_INVOKABLE .

void QVirtualKeyboardInputContext:: commit ()

Commits the current pre-edit text.

注意： 此函数可以被援引，通过元对象系统和从 QML。见 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 .

注意： 此函数可以被援引，通过元对象系统和从 QML。见 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.

注意： 此函数可以被援引，通过元对象系统和从 QML。见 Q_INVOKABLE .
