Java Forum / GUI / April 2004minimum requirement for a java GUI application on linux ?
What is the minimum requirement to use a java GUI on linux ? I guess I need X. But what else do I need ? Do I need GTK for exemple ? What else ? Thanks, John. > What is the minimum requirement to use a java GUI on linux ? <http://java.sun.com/getjava/>  SignatureAndrew Thompson http://www.PhySci.org/ Open-source software suite http://www.PhySci.org/codes/ Web & IT Help http://www.1point1C.org/ Science & Technology >I guess I need X. But what else do I need ? >Do I need GTK for exemple ? What else ? How is it that on Linux it is possible for so many different windowing libraries to co-exist? There must be some basic set of primitives they all use?? Do they let you see results from several different schemes simultaneously? Do they all present the same API to the programmer and are exchangeable? -- Canadian Mind Products, Roedy Green. Coaching, problem solving, economical contract programming.

At the moment there are 2 major toolkits, GTK (written in some kind of OO C) and QT (C++). They are not compatible, although efforts to integrate them in some ways (using the same filechooser, themes, ...) are underway. There's also Motif, which used to be the "standard", but no new programs are written in it. Motif is used for the AWT peers in JDK < 1.5. As of 1.5, AWT is rewritten to use XLib, which is the lowest level library, that talks directly to the XServer. As for primitives, every toolkit has to create it's own widgets, since XLib doesn't know any; you have to use it in terms of line, shapes, ... To answer the OP's question: you need motif, if you're going to use the AWT components.

I am not aware of having any motif library installed and I am runnning any swing application seamlessly. Do you mean that swing applications do not rely on AWT components?

It's only the actual AWT components like Button, List, FileDialog, ... that need Motif (those that have so called "peers", native counterparts). When you only use Swing, Motif is not needed for the part of AWT that Swing uses.
