Desktop Slideshow Settings

[Steven Sroka]

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'.

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)?

aha. the ok/apply/cancel buttons. (this is one time when a picture was only 
worth 5 words. ;)
 
those are handled automatically by KConfigDialog. when the settingsChanged 
signal is emitted, Apply becomes enabled. the state is reset after Apply is 
clicked. (this is actually covered in the Plasma::Wallpaper apidox, but 
sometimes that's more like a buried treasure than a useful learning tool.)
 
Cancel and Ok are always there.
 
assuming you are wanting to do something with Apply, what you are looking for 
is probably the Image::modified() slot in image.cpp. take a look at the things 
that connect to it / call it.
 
or are you trying to do someting else with the buttons in that area?
