|
|

|
|
The TQImageFormatPlugin class provides an abstract base for custom image format plugins.
|
||
|
|
<p>
|
||
|
|
<p> The image format plugin is a simple plugin interface that makes
|
||
|
|
it easy to create custom image formats that can be used
|
||
|
|
transparently by applications.
|
||
|
|
<p> Writing an image format plugin is achieved by subclassing this
|
||
|
|
base class, reimplementing the pure virtual functions <a href="#keys">keys</a>() and
|
||
|
|
<a href="#installIOHandler">installIOHandler</a>(), and exporting the class with the
|
||
|

|
TQ_EXPORT_PLUGIN macro. See the <a href="plugins-howto.html">Plugins
|
||
|
13 years ago
|
documentation</a> for details.
|
||
|
|
<p>See also <a href="plugins.html">Plugins</a>.

|
|
<h3 class=fn><a name="TQImageFormatPlugin"></a>TQImageFormatPlugin::TQImageFormatPlugin ()
|
||
|
|
</h3>
|
||
|
|
Constructs an image format plugin. This is invoked automatically
|
||
|

by the TQ_EXPORT_PLUGIN macro.

<h3 class=fn><a name="~TQImageFormatPlugin"></a>TQImageFormatPlugin::~TQImageFormatPlugin ()
|
||
|
|
</h3>
|
||
|
|
Destroys the image format plugin.
|
||
|
|
<p> You never have to call this explicitly. TQt destroys a plugin
|
||
|
|
automatically when it is no longer used.
