Free graphical user interface gallery software for linux

General Graphics User Interface is an effort to produce a common graphical user interface for any command-line program.

It uses a wizard-like input front end to collect the information needed. It then calls the desired program automatically with all the necessary options.

The user is able to point&click on various options and select them in a convenient way. In order to create a new user-interface, a user doesnt need to know a programming language, since there is a graphical editor for new GGUI "scripts".

RULI stands for Resolver User Layer Interface. Its a library built on top of an asynchronous DNS stub resolver. RULI provides an easy-to-use interface for querying DNS SRV resource records. The goal is to promote wide deployment of SRV-cognizant software. RULI aims to fully support SRV-related standards. There are bindings for PHP, Perl, Guile/Scheme, Java, and Lua. IPv6 is supported.

Now you can understand the benefits of SRV records and please see how RULI can help you.

SRV records are more complex than A records

Handling DNS SRV is not as simple as to deal with ordinary address records. When one performs a query for A records by calling gethostbyname(), he gets a list of addresses which should be contacted in the same order as they were received. For SRV records, there is an additional logic that must be applied to the records, based on their weight and priority, to discover the correct sequence for contacting them.
RULI can handle SRV records for you

The SRV logic is described in RFC 2782. Those who intend to use SRV benefits in their application are expected to implement that exact behavior. RULI can help here: it automatically performs all the SRV logic for you.
Keep focus on your application logic

Application developers probably want to spend time on their business logic; not dealing with the details of the DNS protocol or implementing the SRV specification.

RULI is a tested framework designed to properly fetch SRV records. It saves you time and head aches.
RULI is free as in free beer and in free speech

Graphical certification authority project is a graphical user interface to OpenSSL, RSA/DSA public keys, certificates, signing requests and revokation lists.
The keys have an internal counter, counting its use to avoid a duplicate use of a key for creating a certificate or request.
The Keys are of course encrypted in the db file.
Xca supports next to the usual PEM and DER format of certificates the import and export of PKCS#12 (aka *.pfx) files and the Certificate import from PKCS#7 files.
Certificates can be created by self signing it, by signing it by an other (usually CA) certificate or by signing a PKCS#10 request. Netscape SPKAC is supported since version 0.4.6. The validity dates and x509.v3 extensions can be adjusted to fit ones needs. The use of multiple certificates in CA chains is supported and a tree view of the certificates reflects the dependencies. The application takes care to not create duplicate certificates by checking the serial number(s) on import and creation of certificates.
Certificate Templates can be used to preset the input dialog with reasonable values and to simplify the process of creating certificates and requests.
Issued certificates can be revoked and the revokation list can be created and exported. External revokation lists can be imported and examined.
Enhancements:
- This version fixes an issue where some CA signed certificates were not sorted correctly below that CA.
- Malformed certificates no longer cause a crash.
- The string encoding rules for the distinguished name can now be set in the options dialog and PKCS#10 attributes can be set and inspected.

Cuiterm is a CUI (Composite User Interface) terminal.
CUI (Composite User Interface) is a compound type of user interface which incorporates the features of the GUI (Graphical User Interface) and the CLI (Command Line Interface) by realizing both interface in one area at the same time.
It is absolutely substantial that the CUI contains GUI elements and control language in the same area of the screen at the same time, so the incorporation is complete. CUI is not an optional, alternatively selectable combination of the two communication method but a truly new approach.
An other relevant feature of the CUI method is that it uses generated commands. When the user activated some GUI part of the user interface an automatically generated command appears to complete the task so the user can observ how the CLI part of the user interface can be used.
The cuiterm is a pilot application for the CUI methodology made to demonstrate the power of the composite user interfaces. As terminals are usually used with some shell to start simple UNIX utility programs, the Cui library can be considered as a composite user interface for the shell and some UNIX utilities. The following screenshot shows the starting screen of the cuiterm.
How to use it?
To test the composite user interface first you have to download the cuiterm and and install it. After the installation is complete the program can be started with the cuiterm command.
When the terminal emulator started it can be used the usual way by typing commands into it. Some programs and some complex commands are interpreted by the terminal and colorized (see the list below). For these commands the screen should have active areas usable with the left mouse button by double clicking on them. The output of some programs have floating menus with context sensitive functions. The menus can be accessed by the right mouse button. Some parts of the screen can be used to fire up a text entry field by holding down the left mouse button.
The following list contains some interpreted and processed commands that are worth trying.
ls -l and some variants of it
df
who
w
ps aux
stat
finger
cat /etc/fstab
Enhancements:
- This version contains new features, including an automatic GUI generator which creates dialog boxes from manual pages, a working progress bar, enhanced size bars, and some new command parsers.
- The drag and drop, the speed of the terminal, and the existing parsers were also enhanced.

Console Jabber Client is a Jabber client with text-based user interface resembling those known from popular IRC clients.

CJC is a Jabber/XMPP client for text terminals. Console Jabber Client uses pyxmpp library for XMPP comunication and curses for screen output. It is not finished yet, but still quite usable. Its user interface is resembling those of popular IRC clients like irssi or BitchX.

AntTweakBar allows programmers to quickly add a light and intuitive graphical user interface into graphic programs to interactively tweak them. AntTweakBar is a small and easy to use library that can be readily integrated into OpenGL and DirectX applications.
Program variables can be linked to a graphical control that allows users to modify them. Thus, parameters exposed by programmers can be easily modified. They are displayed into the graphical application through one or more embeded windows called tweak bars.
Design and integration:
The library is designed to minimize programmer work while offering a fast, clean, intuitive and non-invasive graphical interface. For instance, numerical values are automatically mapped to a RotoSlider control for rapid editing.
It is composed of few functions. Common variables like booleans, integers, floats and enums can be directly mapped to a graphic control through pointers or callback functions. Additionnal editing informations like min and max values can be provided. Keyboard shortcuts can also be associated to controls and an help window which summurizes these shortcuts can be displayed. Programmers are not required to design the graphical interface by providing coordinates or by using a visual UI editor. Controls are automatically organized following an optional given hierarchy. In most cases, only one line of code is needed to add a new variable to a tweak bar.
The AntTweakBar library mainly targets graphical programs that need an easy way to tweak parameters and see the result in real-time like 3D demos, light inline game editors, small 3D applications, prototypes, debug facilities of weighter graphical programs, etc.
While the library itself is written in C++, its programming interface is a C interface, and then it can be directly integrated in any C++ or C program.
It has been designed with performance in mind. Embeded in a typical 3D application, its rendering time is almost insignificant. Bars can also be iconified to fully minimize their rendering time.
Enhancements:
- The medium font is antialiased.
- The code now compiles on 64-bit x86 platforms.
- A problem which occurred if the library was initialized or uninitialized more than once was fixed.
- Some other minor fixes were done.
