All I know is that KDE is based on Qt. But it is obvious to me that the program written for KDE can not work without the KDE environment. My question is that Qt already has lots of functions and widgets, why KDE needs its own library? What can I gain if I use KDE library, and how and where I should start if I want to make programs for the KDE (I did not find the documents for the KDE development)? Thank you.

The KDE-environment is something different than the KDE-toolkit. A KDE-app foremost makes use of the toolkit. Therefor it can run without any KDE-desktop running in the background. (It will start needed kde-services though.) Even on gnome. To get the full KDE-experience you can start the KDE-environment. But even with full KDE running you can still execute gtk/gnome apps... > My question is that Qt already has lots of > functions and widgets, why KDE needs its own library? Because the KDE-devs realized that some functions and widgets where missing from Qt. And some of them where missing because Qt is just a toolkit, whereas KDE is a desktop-environment. So all the special things needed for desktop-environments that where not likely to go into Qt are what makes up kdelibs. > What can I gain if I use KDE library, and how and where I should start if I > want to make programs for the KDE Look at the classes and decide for your own... > (I did not find the documents for the KDE > development)? Search *.kde.org, or at least look at the api-docs from kdelibs... Arnold -- [ signature omitted ]

Probably best to start at the KDE web site: http://www.kde.org KDE has hundreds of mailing lists of its own, so asking questions about it on this Qt list are not likely to be too well received. If you want to know the difference between KDE and Qt, I suggest you read around on that web site - then it should become clear to you. Hope this helps. George Goldberg -- [ signature omitted ]

KDE programs run perfectly well outside the KDE desktop and workspace. They can even run on Mac and Windows, so why wouldn't they run on GNOME, XFCE, fvwm, etc.? (I heard some people are trying to get them working with Qt/Embedded Linux so that they could run without X) >My question is that Qt already has lots of >functions and widgets, why KDE needs its own library? Because Qt isn't enough. KDE's job is to produce a consistent look-and-feel across the set of applications. For instance, you're going to find functions that create the Help menu for you, the Settings menu, etc. KDE libraries also integrate with the KDE settings, which you can't do from Qt alone. >What can I gain > if I use KDE library, and how and where I should start if I want to > make programs for the KDE (I did not find the documents for the KDE > development)? You can start by using these resources: the kde-devel mailing list (see http://kde.org/mailinglists/) http://techbase.kde.org/ http://api.kde.org/ -- [ signature omitted ]
