<body class='hmmessage'>Sorry for the late reply, I just switched to KDE 4.6 Beta 1 and it took some time to get stable and fast enough to set up the development dependancies. I'm try to prevent the slideshow wallpaper from changing everytime a user clicks 'OK' after clicking 'Apply'.<br><br>I'm assuming the settingsChanged() signal is emitted twice, once by 'Apply' and once by 'OK'. Is there anyway to stop the signal from emitting from the 'OK' button if the settings aren't changed (because the 'Apply' button has already emitted the signal and done all the necessary work)?<br><br><br>From: aseigo@kde.org<br>To: plasma-devel@kde.org<br>Subject: Re: Desktop Slideshow Settings<br>Date: Mon, 29 Nov 2010 16:07:03 -0800<br><br><pre>On Monday, November 29, 2010, Steven Sroka wrote:<br>> Pic of window and buttons attached.
