TQt - 3.0 includes a new richtext engine which obsoletes TQMultiLineEdit. It is - still included for compatibility reasons. It is now a subclass of - \l TQTextEdit, and provides enough of the old TQMultiLineEdit API to keep old - applications working. - - If you implement something new with TQMultiLineEdit, we suggest using - \l TQTextEdit instead and call TQTextEdit::setTextFormat(TQt::PlainText). - - Although most of the old TQMultiLineEdit API is still available, there is - a few difference. The old TQMultiLineEdit operated on lines, not on - paragraphs. As lines change all the time during wordwrap, the new - richtext engine uses paragraphs as basic elements in the data structure. - All functions (numLines(), textLine(), etc.) that operated on lines, now - operate on paragraphs. Further, getString() has been removed completely. - It revealed too much of the internal data structure. - - Applications which made normal and reasonable use of TQMultiLineEdit - should still work without problems. Some odd usage will require some - porting. In these cases, it may be better to use \l TQTextEdit now. - - <img src=qmlined-m.png> <img src=qmlined-w.png> - - \sa TQTextEdit -*/ - -/*! - \fn bool TQMultiLineEdit::autoUpdate() const - \obsolete -*/ - -/*! - \fn virtual void TQMultiLineEdit::setAutoUpdate( bool ) - \obsolete -*/ - -/*! - \fn int TQMultiLineEdit::totalWidth() const - \obsolete -*/ - -/*! - \fn int TQMultiLineEdit::totalHeight() const - \obsolete -*/ - -/*! - \fn int TQMultiLineEdit::maxLines() const - \obsolete -*/ - -/*! - \fn void TQMultiLineEdit::setMaxLines( int ) - \obsolete -*/ - -/*! - \fn void TQMultiLineEdit::deselect() - \obsolete -*/ - - -class TQMultiLineEditData -{ -}; - - -/*! - Constructs a new, empty, TQMultiLineEdit with parent \a parent called - \a name. -*/ - -TQMultiLineEdit::TQMultiLineEdit( TQWidget *parent , const char *name ) - : TQTextEdit( parent, name ) -{ - d = new TQMultiLineEditData; - setTextFormat( TQt::PlainText ); -} - -/*! \property TQMultiLineEdit::numLines - \brief the number of paragraphs in the editor - - The count includes any empty paragraph at top and bottom, so for an - empty editor this method returns 1. -*/ - -int TQMultiLineEdit::numLines() const -{ - return document()->lastParagraph()->paragId() + 1; -} - -/*! \property TQMultiLineEdit::atEnd - \brief whether the cursor is placed at the end of the text - - \sa atBeginning -*/ - -bool TQMultiLineEdit::atEnd() const -{ - return textCursor()->paragraph() == document()->lastParagraph() && textCursor()->atParagEnd(); -} - - -/*! \property TQMultiLineEdit::atBeginning - \brief whether the cursor is placed at the beginning of the text - - \sa atEnd -*/ - -bool TQMultiLineEdit::atBeginning() const -{ - return textCursor()->paragraph() == document()->firstParagraph() && textCursor()->atParagStart(); -} - -/*!
