## Detailed Description

This class is obsolete. It is provided to keep old source working. We strongly advise against using it in new code.

The TQMultiLineEdit widget is a simple editor for inputting text.

The TQMultiLineEdit was a simple editor widget in former TQt versions. TQt 3.0 includes a new richtext engine which obsoletes TQMultiLineEdit. It is still included for compatibility reasons. It is now a subclass of TQTextEdit, and provides enough of the old TQMultiLineEdit API to keep old applications working.

If you implement something new with TQMultiLineEdit, we suggest using 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 TQTextEdit now.

## Member Function Documentation

### TQMultiLineEdit::TQMultiLineEdit ( TQWidget * parent = 0, const char * name = 0 )

Constructs a new, empty, TQMultiLineEdit with parent parent called name.

### int TQMultiLineEdit::alignment () const

Returns the editor's paragraph alignment. See the "alignment" property for details.

### bool TQMultiLineEdit::atBeginning () const

Returns TRUE if the cursor is placed at the beginning of the text; otherwise returns FALSE. See the "atBeginning" property for details.

### bool TQMultiLineEdit::atEnd () const

Returns TRUE if the cursor is placed at the end of the text; otherwise returns FALSE. See the "atEnd" property for details.

### bool TQMultiLineEdit::autoUpdate () const

This function is obsolete. It is provided to keep old source working. We strongly advise against using it in new code.

### void TQMultiLineEdit::backspace ()`[virtual protected]`

Deletes the character on the left side of the text cursor and moves the cursor one position to the left. If a text has been selected by the user (e.g. by clicking and dragging) the cursor is put at the beginning of the selected text and the selected text is removed. del()

### void TQMultiLineEdit::cursorDown ( bool mark = FALSE )`[virtual protected]`

Moves the cursor one line down. If mark is TRUE, the text is selected.

See also cursorUp(), cursorLeft(), and cursorRight().

### void TQMultiLineEdit::cursorLeft ( bool mark = FALSE, bool wrap = TRUE )`[virtual protected]`

Moves the cursor one character to the left. If mark is TRUE, the text is selected. The wrap parameter is currently ignored.

See also cursorRight(), cursorUp(), and cursorDown().

### TQPoint TQMultiLineEdit::cursorPoint () const`[protected]`

Returns the top center point where the cursor is drawn.

### void TQMultiLineEdit::cursorRight ( bool mark = FALSE, bool wrap = TRUE )`[virtual protected]`

Moves the cursor one character to the right. If mark is TRUE, the text is selected. The wrap parameter is currently ignored.

See also cursorLeft(), cursorUp(), and cursorDown().

### void TQMultiLineEdit::cursorUp ( bool mark = FALSE )`[virtual protected]`

Moves the cursor up one line. If mark is TRUE, the text is selected.

See also cursorDown(), cursorLeft(), and cursorRight().

### void TQMultiLineEdit::cursorWordBackward ( bool mark )

Moves the cursor one word to the left. If mark is TRUE, the text is selected.

See also cursorWordForward().

### void TQMultiLineEdit::cursorWordForward ( bool mark )

Moves the cursor one word to the right. If mark is TRUE, the text is selected.

See also cursorWordBackward().

### void TQMultiLineEdit::deselect ()`[slot]`

This function is obsolete. It is provided to keep old source working. We strongly advise against using it in new code.

### bool TQMultiLineEdit::edited () const

Returns TRUE if the document has been edited by the user; otherwise returns FALSE. See the "edited" property for details.

### void TQMultiLineEdit::end ( bool mark = FALSE )`[virtual protected]`

Moves the text cursor to the right end of the line. If mark is TRUE, text is selected toward the last position. If it is FALSE and the cursor is moved, all selected text is unselected.

See also home().

### bool TQMultiLineEdit::getMarkedRegion ( int * line1, int * col1, int * line2, int * col2 ) const`[protected]`

If there is selected text, sets line1, col1, line2 and col2 to the start and end of the selected region and returns TRUE. Returns FALSE if there is no selected text.

### bool TQMultiLineEdit::hasMarkedText () const

Returns TRUE if there is selected text.

### void TQMultiLineEdit::home ( bool mark = FALSE )`[virtual protected]`

Moves the text cursor to the left end of the line. If mark is TRUE, text is selected toward the first position. If it is FALSE and the cursor is moved, all selected text is unselected.

See also end().

### void TQMultiLineEdit::insertAndMark ( const TQString & str, bool mark )`[virtual protected]`

Inserts str at the current cursor position and selects the text if mark is TRUE.

### void TQMultiLineEdit::insertAt ( const TQString & s, int line, int col, bool mark )`[virtual]`

Inserts string s at paragraph number line, after character number col in the paragraph. If s contains newline characters, new lines are inserted. If mark is TRUE the inserted string will be selected.

The cursor position is adjusted.

### void TQMultiLineEdit::insertLine ( const TQString & txt, int line = -1 )`[virtual]`

Inserts txt at paragraph number line. If line is less than zero, or larger than the number of paragraphs, the new text is put at the end. If txt contains newline characters, several paragraphs are inserted.

The cursor position is not changed.

### void TQMultiLineEdit::killLine ()`[virtual protected]`

Deletes text from the current cursor position to the end of the line. (Note that this function still operates on lines, not paragraphs.)

### int TQMultiLineEdit::lineLength ( int row ) const`[protected]`

Returns the number of characters at paragraph number row. If row is out of range, -1 is returned.

### TQString TQMultiLineEdit::markedText () const

Returns a copy of the selected text.

### int TQMultiLineEdit::maxLines () const

This function is obsolete. It is provided to keep old source working. We strongly advise against using it in new code.

### void TQMultiLineEdit::newLine ()`[virtual protected]`

Splits the paragraph at the current cursor position.

### int TQMultiLineEdit::numLines () const

Returns the number of paragraphs in the editor. See the "numLines" property for details.

### void TQMultiLineEdit::pageDown ( bool mark = FALSE )`[virtual protected]`

Moves the cursor one page down. If mark is TRUE, the text is selected.

### void TQMultiLineEdit::pageUp ( bool mark = FALSE )`[virtual protected]`

Moves the cursor one page up. If mark is TRUE, the text is selected.

### void TQMultiLineEdit::removeLine ( int paragraph )`[virtual]`

Deletes the paragraph at paragraph number paragraph. If paragraph is less than zero or larger than the number of paragraphs, nothing is deleted.

If mark is FALSE, the selection is cleared. otherwise it is extended.

### void TQMultiLineEdit::setEdited ( bool )

Sets whether the document has been edited by the user. See the "edited" property for details.

### void TQMultiLineEdit::setMaxLines ( int )

This function is obsolete. It is provided to keep old source working. We strongly advise against using it in new code.

### TQString TQMultiLineEdit::textLine ( int line ) const
