Two subclasses, <a href="qintvalidator.html">TQIntValidator</a> and -<a href="qdoublevalidator.html">TQDoubleValidator</a>, provide basic numeric-range checking, and <a href="qregexpvalidator.html">TQRegExpValidator</a> provides general checking using a custom <a href="qregexp.html#regular-expression">regular expression</a>. -<p> If the built-in validators aren't sufficient, you can subclass -TQValidator. The class has two virtual functions: <a href="#validate">validate</a>() and -<a href="#fixup">fixup</a>(). -<p> <a href="#validate">validate</a>() must be implemented by every subclass. It returns -<a href="#State-enum">Invalid</a>, <a href="#State-enum">Intermediate</a> or <a href="#State-enum">Acceptable</a> depending on whether -its argument is valid (for the subclass's definition of valid). -<p> These three states require some explanation. An <a href="#State-enum">Invalid</a> string -is <em>clearly</em> invalid. <a href="#State-enum">Intermediate</a> is less obvious: the -concept of validity is slippery when the string is incomplete -(still being edited). TQValidator defines <a href="#State-enum">Intermediate</a> as the -property of a string that is neither clearly invalid nor -acceptable as a final result. <a href="#State-enum">Acceptable</a> means that the string -is acceptable as a final result. One might say that any string -that is a plausible intermediate state during entry of an <a href="#State-enum">Acceptable</a> string is <a href="#State-enum">Intermediate</a>. -<p> Here are some examples: -<p> <ul> -<p> <li> For a line edit that accepts integers from 0 to 999 inclusive, -42 and 123 are <a href="#State-enum">Acceptable</a>, the empty string and 1114 are <a href="#State-enum">Intermediate</a> and asdf is <a href="#State-enum">Invalid</a>. -<p> <li> For an editable combobox that accepts URLs, any well-formed URL -is <a href="#State-enum">Acceptable</a>, "http://www.trolltech.com/," is <a href="#State-enum">Intermediate</a> -(it might be a cut and paste operation that accidentally took in a -comma at the end), the empty string is <a href="#State-enum">Intermediate</a> (the user -might select and delete all of the text in preparation for entering -a new URL), and "http:///./" is <a href="#State-enum">Invalid</a>. -<p> <li> For a spin box that accepts lengths, "11cm" and "1in" are <a href="#State-enum">Acceptable</a>, "11" and the empty string are <a href="#State-enum">Intermediate</a> and -"http://www.trolltech.com" and "hour" are <a href="#State-enum">Invalid</a>. -<p> </ul> -<p> <a href="#fixup">fixup</a>() is provided for validators that can repair some user -errors. The default implementation does nothing. <a href="qlineedit.html">TQLineEdit</a>, for -example, will call <a href="#fixup">fixup</a>() if the user presses Enter (or Return) -and the content is not currently valid. This allows the fixup() -function the opportunity of performing some magic to make an <a href="#State-enum">Invalid</a> string <a href="#State-enum">Acceptable</a>. -<p> TQValidator is typically used with TQLineEdit, <a href="qspinbox.html">TQSpinBox</a> and -<a href="qcombobox.html">TQComboBox</a>. -<p>See also <a href="misc.html">Miscellaneous Classes</a>. - -<hr><h2>Member Type Documentation</h2> -<h3 class=fn><a name="State-enum"></a>TQValidator::State</h3> - -<p> This enum type defines the states in which a validated string can -exist. -<ul> -<li><tt>TQValidator::Invalid</tt> - the string is <em>clearly</em> invalid. -<li><tt>TQValidator::Intermediate</tt> - the string is a plausible intermediate value -during editing. -<li><tt>TQValidator::Acceptable</tt> - the string is acceptable as a final result, -i.e. it is valid. -</ul> -<hr><h2>Member Function Documentation</h2> -<h3 class=fn><a name="TQValidator"></a>TQValidator::TQValidator ( <a href="qobject.html">TQObject</a> * parent, const char * name = 0 ) -</h3> -Sets up the validator.

It need not result in a valid string: -callers of this function must re-test afterwards; the default does -nothing. -<p> Reimplementations of this function can change <em>input</em> even if -they do not produce a valid string. For example, an ISBN validator -might want to delete every character except digits and "-", even -if the result is still not a valid ISBN; a surname validator might -want to remove whitespace from the start and end of the string, -even if the resulting string is not in the list of accepted -surnames. - -<h3 class=fn><a href="qvalidator.html#State-enum">State</a> <a name="validate"></a>TQValidator::validate ( <a href="qstring.html">TQString</a> & input, int & pos ) const<tt> [pure virtual]</tt> -</h3> - -<p> This pure virtual function returns <a href="#State-enum">Invalid</a> if <em>input</em> is -invalid according to this validator's rules, <a href="#State-enum">Intermediate</a> if it -is likely that a little more editing will make the input -acceptable (e.g. the user types '4' into a widget which accepts -integers between 10 and 99) and <a href="#State-enum">Acceptable</a> if the input is -valid. -<p> The function can change <em>input</em> and <em>pos</em> (the cursor position) -if it wants to. - -<p>Reimplemented in <a href="qintvalidator.html#validate">TQIntValidator</a>, <a href="qdoublevalidator.html#validate">TQDoubleValidator</a>, and <a href="qregexpvalidator.html#validate">TQRegExpValidator</a>. -<!-- eof --> -<hr><p> -This file is part of the <a href="index.html">TQt toolkit</a>. -Copyright © 1995-2007 -<a href="http://www.trolltech.com/">Trolltech</a>.
