<h1>KPixmapRegionSelectorWidget Class Reference</h1>
<code>from PyKDE4.kdeui import *</code>
<p>
Inherits: QWidget &#x2192; QObject<br />


<h2>Detailed Description</h2>

<p>KPixmapRegionSelectorWidget is a widget that shows a picture and provides the
user with a friendly way to select a rectangular subregion of the pixmap.
</p>
<p>
NOTE: There are two copies of this .h and the .cpp file, with subtle differences.
One copy is in kdelibs/kdeui, and the other copy is in kdepim/libkdepim
This is because kdepim has to remain backwards compatible. Any changes
to either file should be made to the other.
