Detailed Description

BackgroundChecker is used to perform spell checking without blocking the application.

You can use it as is by calling the checkText function or subclass it and reimplement getMoreText function.

The misspelling signal is emitted whenever a misspelled word is found. The background checker stops right before emitting the signal. So the parent has to call continueChecking function to resume the checking.

done signal is emitted when whole text is spell checked.

Member Function Documentation

bool BackgroundChecker::addWordToPersonal

(

const QString &

word

)

Definition at line 120 of file backgroundchecker.cpp.

void BackgroundChecker::changeLanguage ( const QString &  lang )

bool BackgroundChecker::checkWord

(

const QString &

word

)

Definition at line 115 of file backgroundchecker.cpp.

void BackgroundChecker::continueChecking ( )

virtualslot

After emitting misspelling signal the background checker stops.

The catcher is responsible for calling continueChecking function to resume checking.

Definition at line 135 of file backgroundchecker.cpp.

QString BackgroundChecker::currentContext

const

Definition at line 159 of file backgroundchecker.cpp.

void Sonnet::BackgroundChecker::done ( )

signal

Emitted after the whole text has been spell checked.

QString BackgroundChecker::fetchMoreText ( )

protectedvirtual

This function is called to get the text to spell check.

It will be called continuesly until it returns QString() in which case the done() signal is emitted. Note: the start parameter in mispelling() is not a combined position but a position in the last string returned by fetchMoreText. You need to store the state in the derivatives.

Definition at line 96 of file backgroundchecker.cpp.

void BackgroundChecker::finishedCurrentFeed ( )

protectedvirtual

This function will be called whenever the background checker will be finished text which it got from fetchMoreText.

Definition at line 101 of file backgroundchecker.cpp.

void Sonnet::BackgroundChecker::misspelling ( const QString &  word, int  start  )

signal

Emitted whenever a misspelled word is found.

void Sonnet::BackgroundChecker::replace ( int  start, const QString &  oldText, const QString &  newText  )

slot

Definition at line 164 of file backgroundchecker.cpp.

void BackgroundChecker::restore

(

KConfig *

config

)

Definition at line 68 of file backgroundchecker.cpp.

void BackgroundChecker::setSpeller

(

const Speller &

speller

)

Definition at line 105 of file backgroundchecker.cpp.

void BackgroundChecker::setText

(

const QString &

text

)

This method is used to spell check static text.

It automatically invokes start().

Use fetchMoreText() with start() to spell check a stream.
