Free qt4 software for linux

Qcat is a simple media catalog. It can import data from WhereIsIt. The project is still in pre-alpha stage, so there are no sources available.

Compile:

1. download the source
2.untar it - tar -xzvf qcat-0.5-src.tar.gz
3. cd qcat-dist-0.5
4. here is the tricky part.

Perhaps you use QT 3.3.x. So to compile you have export QT_DIR and PATH for QT4.

Check where is installed QT4. For example if QT4 is in /opt/qt4 type these commands:

export QT_DIR=/opt/qt4
export PATH=/opt/qt4/bin:$PATH

5. run qmake
6. make
7. If all is ok, the result shall be an executable file in qcat-dist-0.5/bin named qcat
8. run it and enjoy.

Installation:

Ive not written any install target, script or so on, so you can just copy "qcat" file somewhere in you path. The install script/target is is in my TODO list.

Some instructions:

This program use SQlite for db backend. During its first run it will create file in ~/.config/QCat in which it will store the configuration. Also it will create your first catalog in your home directory. It will be named defaultCatalog.qcat.

If you want to make shortcut for your CD/DVD drive, go to Tools - Manage Drives. There you can add alias for this drive or any other folder. If you chose that this is optical drive, you have to specify its drive node in /dev/ so the program can read CD/DVD label and mount/unmount the media in it.

In Tools - Manage Icons you can change some of the default icons. They are stored in DB.

Import menu - here you can try to import WhereIsIt xml file. Please notify that if you have groups defined in WhereIsIt file, the hierarchy will be lost. (WherIsIt do not export it), so you have to arrange your disks again. You can use Drag and Drop. At this point only Disk Groups and Disks can be moved.

Saving - there is no need to save your changes, They are committed instantly. Shame on me. I havent write transactions yet.

Locking the catalog - Select catalog properties and click Lock icon. Please note that the passwords are kept in plain text. Shame on me again, so you can just avoid password protection and wait for some new version.

Feel free to explorer. It is almost certain there are plenty of bugs.

Qxmp is a Qt4 media player based on MPlayer for Linux and Unix workstations. Qxmp provides a simple, compact and clean interface to mplayer.

With Qxmp, you can play in just one application:
- .mpg, .mpeg, .wmv, .avi, .asf, .mov, .rm, .ra, .divx, .mkv, .ogm, .mp3, .wav, .ogg, .mka, .wma, .mp2 media files
- .m3u, .pls, .ram, .smi, .asx, .wax, .wvx playlists
- media streams directly from internet
- DVD
- Audio CD (Mplayer must have been compiled with the cdda support)

The "control panel" (with large easily accessible buttons) is always centered at the bottom of the window (no menubar, no toolbar).

Only Mplayer and Qt are required to use Qxmp (no database, no gstreamer , no taglib...).

Qxmp provides a light "playlist editor" and a "bookmarks manager". A static binary package for linux-i386 systems is available on the project home site.

KtikZ application can help you to create TikZ (from the LaTeX pgf package) diagrams for your publications. It requires qt4, LaTeX (pdflatex), the LaTeX preview-latex-style package and pgf itself.

The tool was just a quick hack for making my life easier. It works fine for me. If youd like to improve this little tool just check it out from svn (svn://hackenberger.at/svnroot/ktikz) and send me patches.
