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. </p> <p> <div align="center"><img src="../images/kpixmapregionselectorwidget.png" /><p><strong> "KDE Pixmap Region Selector" </strong></p></div>
