<h1>ReadWritePart Class Reference</h1>
<code>from PyKDE4.kparts import *</code>
<p>
Inherits: <a href="../kparts/KParts.ReadOnlyPart.html">KParts.ReadOnlyPart</a> → <a href="../kparts/KParts.Part.html">KParts.Part</a> → QObject<br />
Namespace: <a href="../kparts/KParts.html">KParts</a><br />
<h2>Detailed Description</h2>
<p>Base class for an "editor" part.
</p>
<p>
This class handles network transparency for you.
Anything that can open a URL, allow modifications, and save
(to the same URL or a different one).
</p>
<p>
A read-write part can be set to read-only mode, using setReadWrite().
</p>
<p>
Part writers :
Any part inheriting ReadWritePart should check isReadWrite
before allowing any action that modifies the part.
The part probably wants to reimplement setReadWrite, disable those
actions. Don't forget to call the parent setReadWrite.
</p>
