|
||
|
|
|
||
|
|
|
||
|
|
The TQMacMime class maps open-standard MIME to Mac flavors.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
<p> TQt's drag-and-drop and clipboard facilities use the MIME standard.
|
||
|
|
On X11, this maps trivially to the Xdnd protocol, but on Mac
|
||
|
|
although some applications use MIME types to describe clipboard
|
||
|
|
formats, others use arbitrary non-standardized naming conventions,
|
||
|
|
or unnamed built-in Mac formats.
|
||
|
|
<p> By instantiating subclasses of TQMacMime that provide conversions
|
||
|
|
between Mac flavors and MIME formats, you can convert proprietary
|
||
|
|
clipboard formats to MIME formats.
|
||
|
|
<p> TQt has predefined support for the following Mac flavors:
|
||
|
|
<ul>
|
||
|
|
<li> kScrapFlavorTypeUnicode - converted to "text/plain;charset=ISO-10646-UCS-2"
|
||
|
|
and supported by <a href="qtextdrag.html">TQTextDrag</a>.
|
||
|
|
<li> kScrapFlavorTypeText - converted to "text/plain;charset=system" or "text/plain"
|
||
|
|
and supported by TQTextDrag.
|
||
|
|
<li> kScrapFlavorTypePicture - converted to "image/format", where format is
|
||
|
|
a <a href="qimage.html#outputFormats">TQt image format</a>,
|
||
|
|
and supported by <a href="qimagedrag.html">TQImageDrag</a>.
|
||
|
|
<li> kDragFlavorTypeHFS - converted to "text/uri-list",
|
||
|
|
and supported by <a href="quridrag.html">TQUriDrag</a>.
|
||
|
|
</ul>
|
||
|
|
<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>().
|
||
|
|

<h3 class=fn><a name="~TQMacMime"></a>TQMacMime::~TQMacMime ()<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><TQMacMime> <a name="all"></a>TQMacMime::all ( TQMacMimeType t )<tt> [static]</tt>

</h3>
|
||
|

|
|
<p> Returns TRUE if the convertor can convert (both ways) between
|
||
|
|
<em>mime</em> and <em>flav</em>; otherwise returns FALSE.
|
||
|
|
<p> All subclasses must reimplement this pure virtual function.

<p> Returns <em>data</em> converted from MIME type <em>mime</em>
|
||
|
|
to Mac flavor <em>flav</em>.
|
||
|
|
<p> Note that Mac flavors must all be self-terminating. The return
|
||
|
|
value may contain trailing data.
|
||
|
|
<p> All subclasses must reimplement this pure virtual function.
