See the +<a href="dnd.html">Drag-and-Drop documentation</a> for more information +on choosing and definition MIME types. +<p> You can check if a MIME type is convertible using <a href="#canConvert">canConvert</a>() and +can perform conversions with <a href="#convertToMime">convertToMime</a>() and <a href="#convertFromMime">convertFromMime</a>(). +<p>See also <a href="draganddrop.html">Drag And Drop Classes</a>, <a href="io.html">Input/Output and Networking</a>, and <a href="misc.html">Miscellaneous Classes</a>. + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="TQWindowsMime"></a>TQWindowsMime::TQWindowsMime () +</h3> +Constructs a new conversion object, adding it to the globally accessed +list of available convertors. + +<h3 class=fn><a name="~TQWindowsMime"></a>TQWindowsMime::~TQWindowsMime ()<tt> [virtual]</tt> +</h3> +Destroys a conversion object, removing it from the global +list of available convertors. + +<h3 class=fn><a href="qptrlist.html">TQPtrList</a><TQWindowsMime> <a name="all"></a>TQWindowsMime::all ()<tt> [static]</tt> +</h3> +Returns a list of all currently defined TQWindowsMime objects. + +<h3 class=fn>bool <a name="canConvert"></a>TQWindowsMime::canConvert ( const char * mime, int cf )<tt> [pure virtual]</tt> +</h3> + +<p> Returns TRUE if the convertor can convert (both ways) between +<em>mime</em> and <em>cf</em>; otherwise returns FALSE. +<p> All subclasses must reimplement this pure virtual function. + +<h3 class=fn>int <a name="cf"></a>TQWindowsMime::cf ( int index )<tt> [pure virtual]</tt> +</h3> + +<p> Returns the Windows Clipboard format supported by this convertor +that is ordinarily at position <em>index</em>.
