<p>QFontMetrics functions calculate the size of characters and
strings for a given font. There are three ways you can create a
QFontMetrics object:</p>
<ol class="1">
<li>Calling the QFontMetrics constructor with a <a href="qfont.html">QFont</a> creates a font metrics object for a
screen-compatible font, i.e. the font cannot be a printer font. If
the font is changed later, the font metrics object is <i>not</i>
updated.
<p>(Note: If you use a printer font the values returned may be
inaccurate. Printer fonts are not always accessible so the nearest
screen font is used if a printer font is supplied.)</p>
</li>
<li><a href="qwidget.html#fontMetrics">QWidget.fontMetrics</a>()
returns the font metrics for a widget's font. This is equivalent to
QFontMetrics(widget->font()). If the widget's font is changed
later, the font metrics object is <i>not</i> updated.</li>
<li><a href="qpainter.html#fontMetrics">QPainter.fontMetrics</a>()
returns the font metrics for a painter's current font. If the
painter's font is changed later, the font metrics object is
<i>not</i> updated.</li>
</ol>
<p>Once created, the object provides functions to access the
individual metrics of the font, its characters, and for strings
rendered in the font.</p>
<p>There are several functions that operate on the font: <a href="qfontmetrics.html#ascent">ascent</a>(), <a href="qfontmetrics.html#descent">descent</a>(), <a href="qfontmetrics.html#height">height</a>(), <a href="qfontmetrics.html#leading">leading</a>() and <a href="qfontmetrics.html#lineSpacing">lineSpacing</a>() return the basic
size properties of the font. The <a href="qfontmetrics.html#underlinePos">underlinePos</a>(), <a href="qfontmetrics.html#overlinePos">overlinePos</a>(), <a href="qfontmetrics.html#strikeOutPos">strikeOutPos</a>() and <a href="qfontmetrics.html#lineWidth">lineWidth</a>() functions, return the
properties of the line that underlines, overlines or strikes out
the characters. These functions are all fast.</p>
<p>There are also some functions that operate on the set of glyphs
in the font: <a href="qfontmetrics.html#minLeftBearing">minLeftBearing</a>(), <a href="qfontmetrics.html#minRightBearing">minRightBearing</a>() and
<a href="qfontmetrics.html#maxWidth">maxWidth</a>(). These are by
necessity slow, and we recommend avoiding them if possible.</p>
<p>For each character, you can get its <a href="qfontmetrics.html#width">width</a>(), <a href="qfontmetrics.html#leftBearing">leftBearing</a>() and <a href="qfontmetrics.html#rightBearing">rightBearing</a>() and find out
whether it is in the font using <a href="qfontmetrics.html#inFont">inFont</a>(). You can also treat the
character as a string, and use the string functions on it.</p>
<p>The string functions include <a href="qfontmetrics.html#width">width</a>(), to return the width of a
string in pixels (or points, for a printer), <a href="qfontmetrics.html#boundingRect">boundingRect</a>(), to return a
rectangle large enough to contain the rendered string, and <a href="qfontmetrics.html#size">size</a>(), to return the size of that
rectangle.</p>
<p>Example:</p>
<pre class="cpp">
<span class="type"><a href="qfont.html">QFont</a></span> font(<span class="string">"times"</span><span class="operator">,</span> <span class="number">24</span>);

</pre><hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QFontMetrics" />QFontMetrics.__init__ (<i>self</i>, <a href="qfont.html">QFont</a>)</h3><p>Constructs a font metrics object for <i>font</i>.</p>
<p>The font metrics will be compatible with the paintdevice used to
create <i>font</i>.</p>
<p>The font metrics object holds the information for the font that
is passed in the constructor at the time it is created, and is not
updated if the font's attributes are changed later.</p>
<p>Use <a href="qfontmetrics.html">QFontMetrics</a>(const <a href="qfont.html">QFont</a> &, <a href="qpaintdevice.html">QPaintDevice</a> *) to get the font metrics
that are compatible with a certain paint device.</p>
<h3 class="fn"><a name="QFontMetrics-2" />QFontMetrics.__init__ (<i>self</i>, <a href="qfont.html">QFont</a>, <a href="qpaintdevice.html">QPaintDevice</a> <i>pd</i>)</h3><p>Constructs a font metrics object for <i>font</i> and
<i>paintdevice</i>.</p>
<p>The font metrics will be compatible with the paintdevice passed.
If the <i>paintdevice</i> is 0, the metrics will be
screen-compatible, ie. the metrics you get if you use the font for
drawing text on a <a href="qwidget.html">widgets</a> or <a href="qpixmap.html">pixmaps</a>, not on a <a href="qpicture.html">QPicture</a> or <a href="qprinter.html">QPrinter</a>.</p>
<p>The font metrics object holds the information for the font that
is passed in the constructor at the time it is created, and is not
updated if the font's attributes are changed later.</p>
<h3 class="fn"><a name="QFontMetrics-3" />QFontMetrics.__init__ (<i>self</i>, <a href="qfontmetrics.html">QFontMetrics</a>)</h3><p>Constructs a copy of <i>fm</i>.</p>
<h3 class="fn"><a name="ascent" />int QFontMetrics.ascent (<i>self</i>)</h3><p>Returns the ascent of the font.</p>
<p>The ascent of a font is the distance from the baseline to the
highest position characters extend to. In practice, some font
designers break this rule, e.g. when they put more than one accent
on top of a character, or to accommodate an unusual character in an
exotic language, so it is possible (though rare) that this value
will be too small.</p>
<p><b>See also</b> <a href="qfontmetrics.html#descent">descent</a>().</p>
<h3 class="fn"><a name="averageCharWidth" />int QFontMetrics.averageCharWidth (<i>self</i>)</h3><p>Returns the average width of glyphs in the font.</p>
<p>This function was introduced in Qt 4.2.</p>
<h3 class="fn"><a name="boundingRect" /><a href="qrect.html">QRect</a> QFontMetrics.boundingRect (<i>self</i>, QChar)</h3><p>Returns the rectangle that is covered by ink if character
<i>ch</i> were to be drawn at the origin of the coordinate
system.</p>
<p>Note that the bounding rectangle may extend to the left of (0,
0) (e.g., for italicized fonts), and that the text output may cover
<i>all</i> pixels in the bounding rectangle. For a space character
the rectangle will usually be empty.</p>
<p>Note that the rectangle usually extends both above and below the
base line.</p>
<p><b>Warning:</b> The width of the returned rectangle is not the
advance width of the character. Use boundingRect(const <a href="qstring.html">QString</a> &) or <a href="qfontmetrics.html#width">width</a>() instead.</p>
<p><b>See also</b> <a href="qfontmetrics.html#width">width</a>().</p>
<h3 class="fn"><a name="boundingRect-2" /><a href="qrect.html">QRect</a> QFontMetrics.boundingRect (<i>self</i>, QString <i>text</i>)</h3><p>Returns the bounding rectangle of the characters in the string
specified by <i>text</i>. The bounding rectangle always covers at
least the set of pixels the text would cover if drawn at (0,
0).</p>
<p>Note that the bounding rectangle may extend to the left of (0,
0), e.g. for italicized fonts, and that the width of the returned
rectangle might be different than what the <a href="qfontmetrics.html#width">width</a>() method returns.</p>
<p>If you want to know the advance width of the string (to layout a
set of strings next to each other), use <a href="qfontmetrics.html#width">width</a>() instead.</p>
<p>Newline characters are processed as normal characters,
<i>not</i> as linebreaks.</p>
<p>The height of the bounding rectangle is at least as large as the
value returned by <a href="qfontmetrics.html#height">height</a>().</p>

<p>The descent is the distance from the base line to the lowest
point characters extend to. In practice, some font designers break
this rule, e.g. to accommodate an unusual character in an exotic
language, so it is possible (though rare) that this value will be
too small.</p>
<p><b>See also</b> <a href="qfontmetrics.html#ascent">ascent</a>().</p>
<h3 class="fn"><a name="elidedText" />QString QFontMetrics.elidedText (<i>self</i>, QString <i>text</i>, <a href="qt.html#TextElideMode-enum">Qt.TextElideMode</a> <i>mode</i>, int <i>width</i>, int <i>flags</i> = 0)</h3><p>If the string <i>text</i> is wider than <i>width</i>, returns an
elided version of the string (i.e., a string with "..." in it).
Otherwise, returns the original string.</p>
<p>The <i>mode</i> parameter specifies whether the text is elided
on the left (e.g., "...tech"), in the middle (e.g., "Tr...ch"), or
on the right (e.g., "Trol...").</p>
<p>The <i>width</i> is specified in pixels, not characters.</p>
<p>The <i>flags</i> argument is optional and currently only
supports <a href="qt.html#TextFlag-enum">Qt.TextShowMnemonic</a>
as value.</p>
<p>The elide mark will follow the <a href="qt.html#LayoutDirection-enum">layout direction</a>; it will be on
the right side of the text for right-to-left layouts, and on the
left side for right-to-left layouts. Note that this behavior is
independent of the text language.</p>
<p>This function was introduced in Qt 4.2.</p>
<h3 class="fn"><a name="height" />int QFontMetrics.height (<i>self</i>)</h3><p>Returns the height of the font.</p>
<p>This is always equal to <a href="qfontmetrics.html#ascent">ascent</a>()+<a href="qfontmetrics.html#descent">descent</a>()+1 (the 1 is for the base
line).</p>
<p><b>See also</b> <a href="qfontmetrics.html#leading">leading</a>() and <a href="qfontmetrics.html#lineSpacing">lineSpacing</a>().</p>
<h3 class="fn"><a name="inFont" />bool QFontMetrics.inFont (<i>self</i>, QChar)</h3><p>Returns true if character <i>ch</i> is a valid character in the
font; otherwise returns false.</p>
<h3 class="fn"><a name="inFontUcs4" />bool QFontMetrics.inFontUcs4 (<i>self</i>, int <i>character</i>)</h3><p>Returns true if the given <i>character</i> encoded in
UCS-4/UTF-32 is a valid character in the font; otherwise returns
false.</p>
<p>This function was introduced in Qt 4.8.</p>
<h3 class="fn"><a name="leading" />int QFontMetrics.leading (<i>self</i>)</h3><p>Returns the leading of the font.</p>
<p>This is the natural inter-line spacing.</p>
<p><b>See also</b> <a href="qfontmetrics.html#height">height</a>()
and <a href="qfontmetrics.html#lineSpacing">lineSpacing</a>().</p>
<h3 class="fn"><a name="leftBearing" />int QFontMetrics.leftBearing (<i>self</i>, QChar)</h3><p>Returns the left bearing of character <i>ch</i> in the font.</p>
<p>The left bearing is the right-ward distance of the left-most
pixel of the character from the logical origin of the character.
This value is negative if the pixels of the character extend to the
left of the logical origin.</p>
<p>See width(<a href="qchar.html">QChar</a>) for a graphical
description of this metric.</p>

<h3 class="fn"><a name="minLeftBearing" />int QFontMetrics.minLeftBearing (<i>self</i>)</h3><p>Returns the minimum left bearing of the font.</p>
<p>This is the smallest leftBearing(char) of all characters in the
font.</p>
<p>Note that this function can be very slow if the font is
large.</p>
<p><b>See also</b> <a href="qfontmetrics.html#minRightBearing">minRightBearing</a>() and

<h3 class="fn"><a name="rightBearing" />int QFontMetrics.rightBearing (<i>self</i>, QChar)</h3><p>Returns the right bearing of character <i>ch</i> in the
font.</p>
<p>The right bearing is the left-ward distance of the right-most
pixel of the character from the logical origin of a subsequent
character. This value is negative if the pixels of the character
extend to the right of the <a href="qfontmetrics.html#width">width</a>() of the character.</p>

<p>The <i>flags</i> argument is the bitwise OR of the following
flags:</p>
<ul>
<li><a href="qt.html#TextFlag-enum">Qt.TextSingleLine</a> ignores
newline characters.</li>
<li><a href="qt.html#TextFlag-enum">Qt.TextExpandTabs</a> expands
tabs (see below)</li>
<li><a href="qt.html#TextFlag-enum">Qt.TextShowMnemonic</a>
interprets "&x" as <u>x</u>; i.e., underlined.</li>
<li>Qt.TextWordBreak breaks the text to fit the rectangle.</li>
</ul>
<p>If <a href="qt.html#TextFlag-enum">Qt.TextExpandTabs</a> is set
in <i>flags</i>, then: if <i>tabArray</i> is non-null, it specifies
a 0-terminated sequence of pixel-positions for tabs; otherwise if
<i>tabStops</i> is non-zero, it is used as the tab spacing (in
pixels).</p>
<p>Newline characters are processed as linebreaks.</p>
<p>Despite the different actual character heights, the heights of
the bounding rectangles of "Yes" and "yes" are the same.</p>

string specified by <i>text</i>. The bounding rectangle always
covers at least the set of pixels the text would cover if drawn at
(0, 0).</p>
<p>Note that the bounding rectangle may extend to the left of (0,
0), e.g. for italicized fonts, and that the width of the returned
rectangle might be different than what the <a href="qfontmetrics.html#width">width</a>() method returns.</p>
<p>If you want to know the advance width of the string (to layout a
set of strings next to each other), use <a href="qfontmetrics.html#width">width</a>() instead.</p>
<p>Newline characters are processed as normal characters,
<i>not</i> as linebreaks.</p>

of <i>text</i>. If <i>len</i> is negative (the default), the entire
string is used.</p>
<p>Note that this value is <i>not</i> equal to <a href="qfontmetrics.html#boundingRect">boundingRect</a>().width();
<a href="qfontmetrics.html#boundingRect">boundingRect</a>() returns
