Introduction

qrwho is a graphical frontend for rwho/rwhod based on Qt.

qrwho has a very simple user interface and can be used to show the users currently logged in and the average loads of the hosts in the network.

User Dialog
User window from qrwho. It shows the users logged in and the according hosts. Host Dialog
Host window from qrwho. It shows a list of active hosts and their actual load.

The usage is very simple, a left mouse click forces an update (by default the display is updated every minute) and a right mouse click opens a popup menu with some configuration and information menu items.

qrwho creates a file named $HOME/.qrwho, which stores the preferences.

Command line options:

qrwho has no special command line options, only the options provided by Qt (these are informations from the QApplication-documentation):

Qt debugging options (not available if Qt was compiled with the NO_DEBUG flag defined):

-nograb, tells Qt to never grab the mouse or the keyboard.
-dograb (only under X11), running under a debugger can cause an implicit -nograb, use -dograb to override.
-sync (only under X11), switches to synchronous mode for debugging.

All Qt programs automatically support the following command line options:

-style= style, sets the application GUI style. Possible values are motif, windows, and platinum.
-session= session, restores the application from an earlier session.

The X11 version of Qt also supports some traditional X11 command line options:

-display display, sets the X display (default is $DISPLAY).
-geometry geometry, sets the client geometry of the main widget.
-fn or -font font, defines the application font.
-bg or -background color, sets the default background color and an application palette (light and dark shades are calculated).
-fg or -foreground color, sets the default foreground color.
-btn or -button color, sets the default button color.
-name name, sets the application name.
-title title, sets the application title (caption).
-visual TrueColor, forces the application to use a TrueColor visual on an 8-bit display.
-ncols count, limits the number of colors allocated in the color cube on a 8-bit display, if the application is using the QApplication::ManyColor color specification. If count is 216 then a 6x6x6 color cube is used (ie. 6 levels of red, 6 of green, and 6 of blue); for other values, a cube approximately proportional to a 2x3x1 cube is used.
-cmap, causes the application to install a private color map on an 8-bit display.

Requirements:

To build this program, you will need:
g++

`qt-2.x:`	or	`qt-3.x:`
Qt 2.x (the actual version of qrwho is compiled with qt-2.3.1) tmake 1.7 (a cross-platform Makefile tool for Qt based programs)		Qt 3.x (the actual version of qrwho is compiled with qt-3.0.0) qmake (is included in the qt-3.0.0 distribution)

Qt-x can be found at www.trolltech.com/developer
and the necessary tmake tool von qt-2.x at www.trolltech.com/developer/download/tmake.html

Compilation and Installation:

`qt-2.x:`		`qt-3.x:`
For building qrwho with Qt-2.x, the adequate paths and environment variables should be set, i.e. QTDIR, TMAKEPATH and the PATH-variable. See the installation documentation for Qt-2.x and tmake.		For building qrwho with Qt-3.x, the adequate paths and environment variables should be set, i.e. QTDIR, QMAKESPEC and the PATH-variable. See the installation documentation for Qt-3.x and qmake.

And finally:

You can build two versions of qrwho, a development and a final version.
For the development version type
make
and for the final version type
make release

This will build the qrwho program.

Currently this program has been tested on Linux and Solaris 2.5.
