image-viewer is a very simple Kommander script. But written following one of the 2-3 tutorials you can find on the net. Included in tarball you can find this guide to introduce in Kommander GUI. The site is: http://applications.linux.com/article.pl?sid=04/12/17/2033227&tid=49 and was written in 2004 by Michał Kosmulski

I know people want to use this great program..but documentations are very poor...this example helps people who wants to learn something about simple array, combobox, label and connections between signals and slots..very very important.

So, i hope the guide and the example will be usefull.

WP Clipart now includes a viewer to expediate the use of the clipart collection. While it is true that any editor will allow you to "browse" your system for images to open or insert, the interface can often be slow, or you have to dig through the system to find the clipart, and often the display of the images (in thumbnail form) is very small.

The Clipart Viewer (CAV) is quick, has a nice size display (up to 240x240 pixels) and the images are displayed, when resized, in their original proportions. In other words, you get a real good look at the images before you pick one. CAV then lets you copy the image in original size to the clipboard to paste into your program. The preview quality and speed are the biggest advantages to using CAV, but there are a couple other advantages that are not immediately obvious.

First, you paste the saved image while keeping CAV open. This allows you to change your mind to try a different clip or copy and paste another image quickly. You dont have to block your editor with another "open" or "insert" dialog to keep going. You can also paste it into a graphics editor if you want to do a little tweaking and not have to find it again.

On Linux, you often cannot get images into the clipboard to use in apps like AbiWord or the Gimp. Simply by keeping CAV open, Abi and Gimp can be pasted into.

I programmed CAV with Python/wxPython/wxGTK. Dependencies should not be a problem on any system as I have created "stand-alone" executables for both Linux and Windows, using cxFreeze and py2exe, respectively, and included these in the downloads for WP Clipart. [They are in the "Viewer" folder.]

Below are a few screenshots. The use of the little app is fairly self-explanatory . . . by clicking on the "caviewer" in the wpclipart/viewer directory (or more easily, by making a symlink or shortcut to that file) CAV will open with its search tree open to the clipart directory.

frob 3D viewer project is a 3D object point/wireframe/polygon viewer - called frob3dv for lack of a better name.

I wrote this version mainly to learn c++. Also it was the first program I wrote after I got a PC (and put linux on it), but it has a long history. Many years ago I wrote a few stacks in Hypercard (on a Mac SE) for editing and displaying 3d shapes. I then ported it to modula-2 , using the free MacMETH compiler, then MOPS, a great free object-oriented programming language and application framework for the mac.

That is where it got most of its current class hierarchy. At that stage it was still only a wire-frame viewer. I then ported it to c++ for the macintosh using the Macintosh Programmers Workshop. When I wiped Windoze off my PC and put an operating system (linux) on it, I ported it to X and added the polygon drawing.

php syslog viewer is a free web application written in PHP for viewing and searching system logs stored in a MySQL database.
Good system administrators review the logs from each system they administer. As the number of systems gets bigger, this becomes a more complex and time consuming task. Eventually the system administrator would like a way to combine the log messages from all of the systems into one central location, but that is not enough. Without a good search facility, finding the information the system administrator needs is like finding a needle in a haystack.
This is where php syslog viewer comes to the rescue. Using a few common Free Software tools (syslog-ng, stunnel, MySQL, apache, and php), php syslog viewer provides a total solution for centralized logging and log management. Client systems send their log files to a server which stores them in a database. php syslog viewer provides the system administrator with a view into that database. php syslog viewer also includes a tool for optimizing searches and archiving older data so that it takes up less room on the disk.
php syslog viewer is Free Software licensed under the GNU GPL (version 2 or later) as published by the Free Software Foundation.
Main features:
- Log Searching
- Real Time Log Viewer
- Automatic Log Rotation
- User Authentication Possibilities
- LDAP
- Active Directory
- Built-in Authentication
- 3rd Party Client API (outputs XML)
- OSI Certified Open Source Software
- Log Archiving

Opcion Font Viewer is a free font viewer written in Java that allows you to view both installed and uninstalled TrueType fonts on Windows, Linux, Unix or Mac.
The main focus of Opcion is to allow you to view your uninstalled fonts so that you install only the fonts you want and keep your system memory free of fonts you dont want.
As you may have experienced, installing the brand new 1000 fonts font pack you just bought on your Windows, Linux, Unix or Mac computer can lead to slow-downs when starting the computer and when loading other programs.
The slow down occurs because the Operating System and certain programs (e.g. word-processors, email clients, graphics editors) need to load all system fonts so that they can be made available to you at any time. This is where Opcion comes in.
Opcion was written to handle the viewing of large font collections, therefore only fonts that you are currently viewing are stored in memory. Although the amount of physical memory you have will effect how many fonts you can view at a time, it will no longer be a limitation to you making use of your entire font library.
Another problem with most Operating Systems default font viewers is that while they are capable of viewing fonts, the default Windows/Linux/Unix font viewers only allows you to view fonts that are already installed and one at a time. Opcion allows you to view TrueType fonts located anywhere and allows you to view system fonts as well.
To help you pick the best font for the job, whether it be for your assignment, project logo or webpage, Opcion provides a list view of either system or other/uninstalled fonts so you may see how a font looks compared to other fonts in your collection.
When you see a font that you feel suits your current job you can simply click on it in the list view and it will be added to a favourites list that can then be saved for future reference or used to install only the fonts you want.
For viewing fonts, seeing how they would appear applied to your name/logo/tagline, and keeping track of which fonts best suit the job is the purpose of Opcion Font Viewer. Opcion allows you to view both installed and uninstalled fonts in different views depending on your needs. Written in Java, Opcion will work on all platforms that the Java Runtime Environment supports (which includes Windows, Mac, Solaris & Linux).
Opcion Font Viewer provdies a default view that allows you to view one font at a time, and a list view which allows you to view multiple fonts at a time. By clicking on fonts you like in the list view you are adding fonts to a faviourties list that Opcion keeps for you. The faviourites list can then be saved for future reference or used in finding out the file names of fonts you wish to install.
Main features:
- Viewing of installed/uninstalled fonts.
- List view of installed/uninstalled fonts.
- Adding/removing of favourite fonts.
- Saving of favourite fonts.
- Customizable sample/display text.
- Customizable font size.
- Customizable font properties (bold, italic, etc.) in sample text area.
- Changeable fonts displayed per page in List View.
Execute Opcion Font Viewer
To execute Opcion Font Viewer in Windows, download the EXE version. For Linux users use the command "java -jar Opcion_v1.1.1.jar" in console/terminal/shortcut.
Exception in thread "main" java.lang.UnsatisfiedLinkError: /usr/java/j2re1.4.1_02/lib/i386/libfontmanager.so: libstdc++-libc6.1-1.so.2: cannot open shared object file: No such file or directory
This error occurs due to backwards compatibility issues with the Java Runtime and libstdc. To fix this problem for RedHat 9.0 install the RPM file compat-libstdc++-7.3.2.96.118.i386.rpm, which can be found on disc 1 of the downloadable distro. For other Linux distributions check rpmfind.net for libstdc++-libc6.1-1.so.2 to see what package you need to install.
An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0x4CAEE920 Function=(null)+0x4CAEE920 Library=/usr/local/lib/SunJava2-1.4.2/lib/i386/libfontmanager.so
This error appears to be a problem with Sun Microsystems Java implementation for Linux, the real cause for this crash is still being investigated. There are no solutions to this problem yet.
Opcion crashes during execution when using Blackdown Java Virtual Machine.
Opcion Font Viewer was programmed for Sun Microsystems JVM, and it uses Suns Java API extensively. Thus, it is highly recommended that you use the latest Java Runtime Environment instead of other JVMs.
Enhancements:
- Added sorting to other fonts list.
