<hr><a name="details"></a><h2>Detailed Description</h2>
<p> The TQDoubleValidator class provides range checking of
floating-point numbers.
<p>
<p> TQDoubleValidator provides an upper bound, a lower bound and a
limit on the number of digits after the decimal point. It does not
provide a <a href="tqvalidator.html#fixup">fixup</a>() function.
<p> You can set the acceptable range in one call with <a href="#setRange">setRange</a>(), or
with <a href="#setBottom">setBottom</a>() and <a href="#setTop">setTop</a>(). Set the number of decimal places
with <a href="#setDecimals">setDecimals</a>(). The <a href="#validate">validate</a>() function returns the validation
state.
<p> <p>See also <a href="tqintvalidator.html">TQIntValidator</a>, <a href="tqregexpvalidator.html">TQRegExpValidator</a>, and <a href="misc.html">Miscellaneous Classes</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQDoubleValidator"></a>TQDoubleValidator::TQDoubleValidator ( <a href="tqobject.html">TQObject</a> * parent, const char * name = 0 )
</h3>
Constructs a validator object with parent <em>parent</em>, called <em>name</em>, which accepts any double.
<h3 class=fn><a name="TQDoubleValidator-2"></a>TQDoubleValidator::TQDoubleValidator ( double bottom, double top, int decimals, <a href="tqobject.html">TQObject</a> * parent, const char * name = 0 )
</h3>
Constructs a validator object with parent <em>parent</em>, called <em>name</em>. This validator will accept doubles from <em>bottom</em> to <em>top</em>
inclusive, with up to <em>decimals</em> digits after the decimal point.
<h3 class=fn><a name="~TQDoubleValidator"></a>TQDoubleValidator::~TQDoubleValidator ()
</h3>
Destroys the validator, freeing any resources used.
<h3 class=fn>double <a name="bottom"></a>TQDoubleValidator::bottom () const
</h3><p>Returns the validator's minimum acceptable value.
See the <a href="tqdoublevalidator.html#bottom-prop">"bottom"</a> property for details.
<h3 class=fn>int <a name="decimals"></a>TQDoubleValidator::decimals () const
</h3><p>Returns the validator's maximum number of digits after the decimal point.
See the <a href="tqdoublevalidator.html#decimals-prop">"decimals"</a> property for details.
<h3 class=fn>void <a name="setBottom"></a>TQDoubleValidator::setBottom ( double )
</h3><p>Sets the validator's minimum acceptable value.
See the <a href="tqdoublevalidator.html#bottom-prop">"bottom"</a> property for details.
<h3 class=fn>void <a name="setDecimals"></a>TQDoubleValidator::setDecimals ( int )
</h3><p>Sets the validator's maximum number of digits after the decimal point.
See the <a href="tqdoublevalidator.html#decimals-prop">"decimals"</a> property for details.
<h3 class=fn>void <a name="setRange"></a>TQDoubleValidator::setRange ( double minimum, double maximum, int decimals = 0 )<tt> [virtual]</tt>
</h3>
Sets the validator to accept doubles from <em>minimum</em> to <em>maximum</em>
inclusive, with at most <em>decimals</em> digits after the decimal
point.
<h3 class=fn>void <a name="setTop"></a>TQDoubleValidator::setTop ( double )
</h3><p>Sets the validator's maximum acceptable value.
See the <a href="tqdoublevalidator.html#top-prop">"top"</a> property for details.
<h3 class=fn>double <a name="top"></a>TQDoubleValidator::top () const
</h3><p>Returns the validator's maximum acceptable value.
See the <a href="tqdoublevalidator.html#top-prop">"top"</a> property for details.
<h3 class=fn><a href="tqvalidator.html#State-enum">TQValidator::State</a> <a name="validate"></a>TQDoubleValidator::validate ( <a href="tqstring.html">TQString</a> & input, int & ) const<tt> [virtual]</tt>
</h3>
Returns <a href="tqvalidator.html#State-enum">Acceptable</a> if the string <em>input</em> contains a double
that is within the valid range and is in the correct format.
<p> Returns <a href="tqvalidator.html#State-enum">Intermediate</a> if <em>input</em> contains a double that is
outside the range or is in the wrong format, e.g. with too many
digits after the decimal point or is empty.
<p> Returns <a href="tqvalidator.html#State-enum">Invalid</a> if the <em>input</em> is not a double.
<p> Note: If the valid range consists of just positive doubles (e.g. 0.0 - 100.0)
and <em>input</em> is a negative double then Invalid is returned.
<p>Reimplemented from <a href="tqvalidator.html#validate">TQValidator</a>.
