Detailed Description

\reentrant

The QTextLayout class is used to lay out and render text. \inmodule QtGui

It offers many features expected from a modern text layout engine, including Unicode compliant rendering, line breaking and handling of cursor positioning. It can also produce and render device independent layout, something that is important for WYSIWYG applications.

The class has a rather low level API and unless you intend to implement your own text rendering for some specialized widget, you probably won't need to use it directly.

QTextLayout can be used with both plain and rich text.

QTextLayout can be used to create a sequence of QTextLine instances with given widths and can position them independently on the screen. Once the layout is done, these lines can be drawn on a paint device.

The text to be laid out can be provided in the constructor or set with setText().

The layout can be seen as a sequence of QTextLine objects; use createLine() to create a QTextLine instance, and lineAt() or lineForTextPosition() to retrieve created lines.

Here is a code snippet that demonstrates the layout phase:

int leading = fontMetrics.leading();
qreal height = 0;
textLayout.setCacheEnabled(true);
textLayout.beginLayout();
while (true) {
    QTextLine line = textLayout.createLine();
    if (!line.isValid())
        break;
 
    line.setLineWidth(lineWidth);
    height += leading;
    line.setPosition(QPointF(0, height));
    height += line.height();
}
textLayout.endLayout();

The text can then be rendered by calling the layout's draw() function:

QPainter painter(this);

textLayout.draw(&painter, QPoint(0, 0));

It is also possible to draw each line individually, for instance to draw the last line that fits into a widget elided:

QPainter painter(this);
QFontMetrics fontMetrics = painter.fontMetrics();
 
int lineSpacing = fontMetrics.lineSpacing();
int y = 0;
 
QTextLayout textLayout(content, painter.font());
textLayout.beginLayout();
while (true) {
    QTextLine line = textLayout.createLine();
 
    if (!line.isValid())
        break;
 
    line.setLineWidth(width());
    const int nextLineY = y + lineSpacing;
 
    if (height() >= nextLineY + lineSpacing) {
        line.draw(&painter, QPoint(0, y));
        y = nextLineY;
    } else {
        const QString lastLine = content.mid(line.textStart());
        const QString elidedLastLine = fontMetrics.elidedText(lastLine, Qt::ElideRight, width());
        painter.drawText(QPoint(0, y + fontMetrics.ascent()), elidedLastLine);
        line = textLayout.createLine();
        break;
    }
}
textLayout.endLayout();

For a given position in the text you can find a valid cursor position with isValidCursorPosition(), nextCursorPosition(), and previousCursorPosition().

The QTextLayout itself can be positioned with setPosition(); it has a boundingRect(), and a minimumWidth() and a maximumWidth().

◆ GlyphRunRetrievalFlag

enum QTextLayout::GlyphRunRetrievalFlag : quint16

Since: 6.5

GlyphRunRetrievalFlag specifies flags passed to the glyphRuns() functions to determine which properties of the layout are returned in the QGlyphRun objects. Since each property will consume memory and may require additional allocations, it is a good practice to only request the properties you will need to access later.

\value RetrieveGlyphIndexes Retrieves the indexes in the font which correspond to the glyphs. \value RetrieveGlyphPositions Retrieves the relative positions of the glyphs in the layout. \value RetrieveStringIndexes Retrieves the indexes in the original string that correspond to each of the glyphs. \value RetrieveString Retrieves the original source string from the layout. \value RetrieveAll Retrieves all available properties of the layout. \omitvalue DefaultRetrievalFlags

Member Function Documentation

◆ beginLayout()

void QTextLayout::beginLayout ( )

Begins the layout process.

Warning: This will invalidate the layout, so all existing QTextLine objects that refer to the previous contents should now be discarded.

See also: endLayout()

Definition at line 594 of file qtextlayout.cpp.

◆ boundingRect()

QRectF QTextLayout::boundingRect ( ) const

The smallest rectangle that contains all the lines in the layout.

Definition at line 877 of file qtextlayout.cpp.

◆ cacheEnabled()

bool QTextLayout::cacheEnabled ( ) const

Returns true if the complete layout information is cached; otherwise returns false.

See also: setCacheEnabled()

Definition at line 557 of file qtextlayout.cpp.

◆ clearFormats()

void QTextLayout::clearFormats ( )

Since: 5.6

Clears the list of additional formats supported by the text layout.

See also: formats(), setFormats()

Definition at line 531 of file qtextlayout.cpp.

◆ clearLayout()

void QTextLayout::clearLayout ( )

Since: 4.4

Clears the line information in the layout. After having called this function, lineCount() returns 0.

Warning: This will invalidate the layout, so all existing QTextLine objects that refer to the previous contents should now be discarded.

Definition at line 639 of file qtextlayout.cpp.

◆ createLine()

QTextLine QTextLayout::createLine ( )

Returns a new text line to be laid out if there is text to be inserted into the layout; otherwise returns an invalid text line.

The text layout creates a new line object that starts after the last line in the layout, or at the beginning if the layout is empty. The layout maintains an internal cursor, and each line is filled with text from the cursor position onwards when the QTextLine::setLineWidth() function is called.

Once QTextLine::setLineWidth() is called, a new line can be created and filled with text. Repeating this process will lay out the whole block of text contained in the QTextLayout. If there is no text left to be inserted into the layout, the QTextLine returned will not be valid (isValid() will return false).

Definition at line 784 of file qtextlayout.cpp.

◆ cursorMoveStyle()

Qt::CursorMoveStyle QTextLayout::cursorMoveStyle ( ) const

The cursor movement style of this QTextLayout.

The default is Qt::LogicalMoveStyle.

See also: setCursorMoveStyle()

Definition at line 581 of file qtextlayout.cpp.

◆ draw()

void QTextLayout::draw	(	QPainter *	p,
		const QPointF &	pos,
		const QList< FormatRange > &	selections = QList<FormatRange>(),
		const QRectF &	clip = QRectF() ) const

Draws the whole layout on the painter p at the position specified by pos.

The rendered layout includes the given selections and is clipped within the rectangle specified by clip.

Definition at line 1088 of file qtextlayout.cpp.

◆ drawCursor() [1/2]

void QTextLayout::drawCursor	(	QPainter *	painter,
		const QPointF &	position,
		int	cursorPosition ) const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.Draws a text cursor with the current pen at the given position using the painter specified.

The corresponding position within the text is specified by cursorPosition.

Definition at line 1272 of file qtextlayout.cpp.

◆ drawCursor() [2/2]

void QTextLayout::drawCursor	(	QPainter *	painter,
		const QPointF &	position,
		int	cursorPosition,
		int	width ) const

Draws a text cursor with the current pen and the specified width at the given position using the painter specified.

The corresponding position within the text is specified by cursorPosition.

Definition at line 1284 of file qtextlayout.cpp.

◆ endLayout()

void QTextLayout::endLayout ( )

Ends the layout process.

See also: beginLayout()

Definition at line 613 of file qtextlayout.cpp.

◆ engine()

QTextEngine * QTextLayout::engine ( ) const

inline

Returns the text engine used to render the text layout.

Definition at line 173 of file qtextlayout.h.

◆ font()

QFont QTextLayout::font ( ) const

See also: setFont()

Definition at line 406 of file qtextlayout.cpp.

◆ formats()

QList< QTextLayout::FormatRange > QTextLayout::formats ( ) const

Since: 5.6

Returns the list of additional formats supported by the text layout.

See also: setFormats(), clearFormats()

Definition at line 519 of file qtextlayout.cpp.

◆ glyphRuns()

QList< QGlyphRun > QTextLayout::glyphRuns	(	int	from = -1,
		int	length = -1,
		GlyphRunRetrievalFlags	flags = DefaultRetrievalFlags ) const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Returns the glyph indexes and positions for all glyphs corresponding to the length characters starting at the position from in this QTextLayout.

This is an expensive function, and should not be called in a time sensitive context.

If from is less than zero, then the glyph run will begin at the first character in the layout. If length is less than zero, it will span the entire string from the start position.

The retrievalFlags specifies which properties of the QGlyphRun will be retrieved from the layout. To minimize allocations and memory consumption, this should be set to include only the properties that you need to access later.

Since: 6.5

See also: draw(), QPainter::drawGlyphRun()

Definition at line 1034 of file qtextlayout.cpp.

◆ isValidCursorPosition()

bool QTextLayout::isValidCursorPosition ( int pos ) const

Returns true if position pos is a valid cursor position.

In a Unicode context some positions in the text are not valid cursor positions, because the position is inside a Unicode surrogate or a grapheme cluster.

A grapheme cluster is a sequence of two or more Unicode characters that form one indivisible entity on the screen. For example the latin character ‘\unicode{0xC4}’ can be represented in Unicode by two characters, ‘A’ (0x41), and the combining diaeresis (0x308). A text cursor can only validly be positioned before or after these two characters, never between them since that wouldn't make sense. In indic languages every syllable forms a grapheme cluster.

Definition at line 760 of file qtextlayout.cpp.

◆ leftCursorPosition()

int QTextLayout::leftCursorPosition ( int oldPos ) const

Returns the cursor position to the left of oldPos, next to it.

It's dependent on the visual position of characters, after bi-directional reordering.

See also: rightCursorPosition(), previousCursorPosition()

Definition at line 738 of file qtextlayout.cpp.

◆ lineAt()

QTextLine QTextLayout::lineAt ( int i ) const

Returns the {i}-th line of text in this text layout.

See also: lineCount(), lineForTextPosition()

Definition at line 835 of file qtextlayout.cpp.

◆ lineCount()

int QTextLayout::lineCount ( ) const

Returns the number of lines in this text layout.

See also: lineAt()

Definition at line 825 of file qtextlayout.cpp.

◆ lineForTextPosition()

QTextLine QTextLayout::lineForTextPosition ( int pos ) const

Returns the line that contains the cursor position specified by pos.

See also: isValidCursorPosition(), lineAt()

Definition at line 845 of file qtextlayout.cpp.

◆ maximumWidth()

qreal QTextLayout::maximumWidth ( ) const

The maximum width the layout could expand to; this is essentially the width of the entire text.

Warning: This function only returns a valid value after the layout has been done.

See also: minimumWidth()

Definition at line 921 of file qtextlayout.cpp.

◆ minimumWidth()

qreal QTextLayout::minimumWidth ( ) const

The minimum width the layout needs.

This is the width of the layout's smallest non-breakable substring.

Warning: This function only returns a valid value after the layout has been done.

See also: maximumWidth()

Definition at line 907 of file qtextlayout.cpp.

◆ nextCursorPosition()

int QTextLayout::nextCursorPosition	(	int	oldPos,
		CursorMode	mode = SkipCharacters ) const

Returns the next valid cursor position after oldPos that respects the given cursor mode.

Returns value of oldPos, if oldPos is not a valid cursor position.

See also: isValidCursorPosition(), previousCursorPosition()

Definition at line 651 of file qtextlayout.cpp.

◆ position()

QPointF QTextLayout::position ( ) const

Since: 4.2

The global position of the layout. This is independent of the bounding rectangle and of the layout process.

See also: setPosition()

Definition at line 859 of file qtextlayout.cpp.

◆ preeditAreaPosition()

int QTextLayout::preeditAreaPosition ( ) const

Returns the position of the area in the text layout that will be processed before editing occurs.

See also: preeditAreaText()

Definition at line 481 of file qtextlayout.cpp.

Returns the text that is inserted in the layout before editing occurs.

See also: preeditAreaPosition()

Definition at line 491 of file qtextlayout.cpp.

◆ previousCursorPosition()

int QTextLayout::previousCursorPosition	(	int	oldPos,
		CursorMode	mode = SkipCharacters ) const

Returns the first valid cursor position before oldPos that respects the given cursor mode.

Returns value of oldPos, if oldPos is not a valid cursor position.

See also: isValidCursorPosition(), nextCursorPosition()

Definition at line 687 of file qtextlayout.cpp.

◆ rightCursorPosition()

int QTextLayout::rightCursorPosition ( int oldPos ) const

Returns the cursor position to the right of oldPos, next to it.

It's dependent on the visual position of characters, after bi-directional reordering.

Definition at line 724 of file qtextlayout.cpp.

◆ setCacheEnabled()

void QTextLayout::setCacheEnabled ( bool enable )

Enables caching of the complete layout information if enable is true; otherwise disables layout caching.

Usually QTextLayout throws most of the layouting information away after a call to endLayout() to reduce memory consumption. If you however want to draw the laid out text directly afterwards enabling caching might speed up drawing significantly.

See also: cacheEnabled()
