QTextLayout class is used to lay out and render text.</p>
<p>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.</p>
<p>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.</p>
<p>QTextLayout can be used with both plain and rich text.</p>
<p>QTextLayout can be used to create a sequence of <a href="qtextline.html">QTextLine</a> 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.</p>
<p>The text to be laid out can be provided in the constructor or
set with <a href="qtextlayout.html#setText">setText</a>().</p>
<p>The layout can be seen as a sequence of <a href="qtextline.html">QTextLine</a> objects; use <a href="qtextlayout.html#createLine">createLine</a>() to create a <a href="qtextline.html">QTextLine</a> instance, and <a href="qtextlayout.html#lineAt">lineAt</a>() or <a href="qtextlayout.html#lineForTextPosition">lineForTextPosition</a>() to
retrieve created lines.</p>
<p>Here is a code snippet that demonstrates the layout phase:</p>
<pre class="cpp">
<span class="type">int</span> leading <span class="operator">=</span> fontMetrics<span class="operator">.</span>leading();
<span class="type"><a href="qtcore.html#qreal-typedef">qreal</a></span> height <span class="operator">=</span> <span class="number">0</span>;
textLayout<span class="operator">.</span><a href="qtextlayout.html#beginLayout">beginLayout</a>();
<span class="keyword">while</span> (<span class="number">1</span>) {
<span class="type"><a href="qtextline.html">QTextLine</a></span> line <span class="operator">=</span> textLayout<span class="operator">.</span>createLine();
<span class="keyword">if</span> (<span class="operator">!</span>line<span class="operator">.</span>isValid())
<span class="keyword">break</span>;
line<span class="operator">.</span>setLineWidth(lineWidth);
height <span class="operator">+</span><span class="operator">=</span> leading;
line<span class="operator">.</span>setPosition(<span class="type"><a href="qpointf.html">QPointF</a></span>(<span class="number">0</span><span class="operator">,</span> height));
height <span class="operator">+</span><span class="operator">=</span> line<span class="operator">.</span>height();
}
textLayout<span class="operator">.</span><a href="qtextlayout.html#endLayout">endLayout</a>();
</pre>
<p>The text can then be rendered by calling the layout's <a href="qtextlayout.html#draw">draw</a>() function:</p>
<pre class="cpp">
<span class="type"><a href="qpainter.html">QPainter</a></span> painter(<span class="keyword">this</span>);
textLayout<span class="operator">.</span><a href="qtextlayout.html#draw">draw</a>(<span class="operator">&</span>painter<span class="operator">,</span> <span class="type"><a href="qpoint.html">QPoint</a></span>(<span class="number">0</span><span class="operator">,</span> <span class="number">0</span>));
</pre>
<p>For a given position in the text you can find a valid cursor
position with <a href="qtextlayout.html#isValidCursorPosition">isValidCursorPosition</a>(),
<a href="qtextlayout.html#nextCursorPosition">nextCursorPosition</a>(), and
<a href="qtextlayout.html#previousCursorPosition">previousCursorPosition</a>().</p>
<p>The QTextLayout itself can be positioned with <a href="qtextlayout.html#setPosition">setPosition</a>(); it has a <a href="qtextlayout.html#boundingRect">boundingRect</a>(), and a <a href="qtextlayout.html#minimumWidth">minimumWidth</a>() and a <a href="qtextlayout.html#maximumWidth">maximumWidth</a>().</p>

the specified <i>font</i>.</p>
<p>All the metric and layout calculations will be done in terms of
the paint device, <i>paintdevice</i>. If <i>paintdevice</i> is 0
the calculations will be done in screen metrics.</p>
<h3 class="fn"><a name="QTextLayout-4" />QTextLayout.__init__ (<i>self</i>, <a href="qtextblock.html">QTextBlock</a> <i>b</i>)</h3><h3 class="fn"><a name="additionalFormats" />unknown-type QTextLayout.additionalFormats (<i>self</i>)</h3><p>Returns the list of additional formats supported by the text
layout.</p>
<p><b>See also</b> <a href="qtextlayout.html#setAdditionalFormats">setAdditionalFormats</a>()
and <a href="qtextlayout.html#clearAdditionalFormats">clearAdditionalFormats</a>().</p>
<h3 class="fn"><a name="beginLayout" />QTextLayout.beginLayout (<i>self</i>)</h3><p>Begins the layout process.</p>
<p><b>See also</b> <a href="qtextlayout.html#endLayout">endLayout</a>().</p>
<h3 class="fn"><a name="boundingRect" /><a href="qrectf.html">QRectF</a> QTextLayout.boundingRect (<i>self</i>)</h3><p>The smallest rectangle that contains all the lines in the
layout.</p>
<h3 class="fn"><a name="cacheEnabled" />bool QTextLayout.cacheEnabled (<i>self</i>)</h3><p>Returns true if the complete layout information is cached;
otherwise returns false.</p>
<p><b>See also</b> <a href="qtextlayout.html#setCacheEnabled">setCacheEnabled</a>().</p>
<h3 class="fn"><a name="clearAdditionalFormats" />QTextLayout.clearAdditionalFormats (<i>self</i>)</h3><p>Clears the list of additional formats supported by the text
layout.</p>
<p><b>See also</b> <a href="qtextlayout.html#additionalFormats">additionalFormats</a>() and
<a href="qtextlayout.html#setAdditionalFormats">setAdditionalFormats</a>().</p>
<h3 class="fn"><a name="clearLayout" />QTextLayout.clearLayout (<i>self</i>)</h3><p>Clears the line information in the layout. After having called
this function, <a href="qtextlayout.html#lineCount">lineCount</a>()
returns 0.</p>
<p>This function was introduced in Qt 4.4.</p>
<h3 class="fn"><a name="createLine" /><a href="qtextline.html">QTextLine</a> QTextLayout.createLine (<i>self</i>)</h3><p>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.</p>
<p>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 <a href="qtextline.html#setLineWidth">QTextLine.setLineWidth</a>()
function is called.</p>
<p>Once <a href="qtextline.html#setLineWidth">QTextLine.setLineWidth</a>() 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
<a href="qtextlayout.html">QTextLayout</a>. If there is no text
left to be inserted into the layout, the <a href="qtextline.html">QTextLine</a> returned will not be valid
(isValid() will return false).</p>
<h3 class="fn"><a name="cursorMoveStyle" /><a href="qt.html#CursorMoveStyle-enum">Qt.CursorMoveStyle</a> QTextLayout.cursorMoveStyle (<i>self</i>)</h3><p>The cursor movement style of this <a href="qtextlayout.html">QTextLayout</a>. The default is <a href="qt.html#CursorMoveStyle-enum">Qt.LogicalMoveStyle</a>.</p>
<p>This function was introduced in Qt 4.8.</p>
<p><b>See also</b> <a href="qtextlayout.html#setCursorMoveStyle">setCursorMoveStyle</a>().</p>
<h3 class="fn"><a name="draw" />QTextLayout.draw (<i>self</i>, <a href="qpainter.html">QPainter</a> <i>p</i>, <a href="qpointf.html">QPointF</a> <i>pos</i>, unknown-type <i>selections</i> = QVector<QTextLayout.FormatRange>(), <a href="qrectf.html">QRectF</a> <i>clip</i> = QRectF())</h3><p>Draws the whole layout on the painter <i>p</i> at the position
specified by <i>pos</i>. The rendered layout includes the given
<i>selections</i> and is clipped within the rectangle specified by
<i>clip</i>.</p>
<h3 class="fn"><a name="drawCursor" />QTextLayout.drawCursor (<i>self</i>, <a href="qpainter.html">QPainter</a> <i>p</i>, <a href="qpointf.html">QPointF</a> <i>pos</i>, int <i>cursorPosition</i>)</h3><p>Draws a text cursor with the current pen and the specified
<i>width</i> at the given <i>position</i> using the <i>painter</i>
specified. The corresponding position within the text is specified
by <i>cursorPosition</i>.</p>
<h3 class="fn"><a name="drawCursor-2" />QTextLayout.drawCursor (<i>self</i>, <a href="qpainter.html">QPainter</a> <i>p</i>, <a href="qpointf.html">QPointF</a> <i>pos</i>, int <i>cursorPosition</i>, int <i>width</i>)</h3><p>This is an overloaded function.</p>
<p>Draws a text cursor with the current pen at the given
<i>position</i> using the <i>painter</i> specified. The
corresponding position within the text is specified by
<i>cursorPosition</i>.</p>
<h3 class="fn"><a name="endLayout" />QTextLayout.endLayout (<i>self</i>)</h3><p>Ends the layout process.</p>
<p><b>See also</b> <a href="qtextlayout.html#beginLayout">beginLayout</a>().</p>
<h3 class="fn"><a name="font" /><a href="qfont.html">QFont</a> QTextLayout.font (<i>self</i>)</h3><p>Returns the current font that is used for the layout, or a
default font if none is set.</p>
<p><b>See also</b> <a href="qtextlayout.html#setFont">setFont</a>().</p>
<h3 class="fn"><a name="glyphRuns" />unknown-type QTextLayout.glyphRuns (<i>self</i>)</h3><p>Returns the glyph indexes and positions for all glyphs in this
<a href="qtextlayout.html">QTextLayout</a>. This is an expensive
function, and should not be called in a time sensitive context.</p>
<p>This function was introduced in Qt 4.8.</p>
<p><b>See also</b> <a href="qtextlayout.html#draw">draw</a>() and
<a href="qpainter.html#drawGlyphRun">QPainter.drawGlyphRun</a>().</p>
<h3 class="fn"><a name="isValidCursorPosition" />bool QTextLayout.isValidCursorPosition (<i>self</i>, int <i>pos</i>)</h3><p>/ Returns true if position <i>pos</i> is a valid cursor
position.</p>
<p>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.</p>
<p>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 `Ä' can be represented in Unicode
by two characters, `A' (0x41), and the combining diaresis (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.</p>
<h3 class="fn"><a name="leftCursorPosition" />int QTextLayout.leftCursorPosition (<i>self</i>, int <i>oldPos</i>)</h3><p>Returns the cursor position to the left of <i>oldPos</i>, next
to it. The position is dependent on the visual position of
characters, after bi-directional reordering.</p>
<p>This function was introduced in Qt 4.8.</p>
<p><b>See also</b> <a href="qtextlayout.html#rightCursorPosition">rightCursorPosition</a>()
and <a href="qtextlayout.html#previousCursorPosition">previousCursorPosition</a>().</p>
<h3 class="fn"><a name="lineAt" /><a href="qtextline.html">QTextLine</a> QTextLayout.lineAt (<i>self</i>, int <i>i</i>)</h3><p>Returns the <i>i</i>-th line of text in this text layout.</p>
