<h1>CoordinatesToCursorInterface Class Reference</h1>
<code>from PyKDE4.ktexteditor import *</code>
<p>
Namespace: <a href="../ktexteditor/KTextEditor.html">KTextEditor</a><br />
<h2>Detailed Description</h2>
<p>Pixel coordinate to Cursor extension interface for the View.
</p>
<p>
<b>Introduction </b>
</p>
<p>
The CoordinatesToCursorInterface makes it possible to map a
pixel coordinate to a cursor position. To map a cursor position
to pixel coordinates use one of
- KTextEditor.View.cursorToCoordinate()
- KTextEditor.View.cursorPositionCoordinates()
</p>
<p>
<b>Accessing the CoordinatesToCursorInterface </b>
</p>
<p>
The CoordinatesToCursorInterface is an extension interface for a
View, i.e. the View inherits the interface provided that the
used KTextEditor library implements the interface. Use qobject_cast to
access the interface:
<pre class="fragment">
// view is of type KTextEditor.View*
KTextEditor.CoordinatesToCursorInterface *iface =
qobject_cast<KTextEditor.CoordinatesToCursorInterface*>( view );
if( iface ) {
// the implementation supports the interface
// do stuff
}
</pre>
