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 window from qrwho. It shows the users logged in and the according hosts.
Host window from qrwho. It shows a list of active hosts and their actual load.
qrwho creates a file named $HOME/.qrwho, which stores the preferences.
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
-session=session, restores the application from an earlier session.
The X11 version of Qt also supports some traditional X11 command line options:
-displaydisplay, sets the X display (default is $DISPLAY).
-geometrygeometry, sets the client geometry of the main widget.
-fontfont, defines the application font.
-backgroundcolor, sets the default background color and an application palette (light and dark shades are calculated).
-foregroundcolor, sets the default foreground color.
-buttoncolor, sets the default button color.
-namename, sets the application name.
-titletitle, sets the application title (caption).
-visual TrueColor,forces the application to use a TrueColor visual on an 8-bit display.
-ncolscount, limits the number of colors allocated in the color cube on a 8-bit display, if the application is using the
QApplication::ManyColorcolor 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.
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)
|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.|
You can build two versions of qrwho, a development and a final version.
For the development version type
and for the final version type
This will build the qrwho program.
Currently this program has been tested on Linux and Solaris 2.5.
