To begin, let's look at how we might use +&kstart; to customize the behaviour of a +&kcalc; window. The command we'll use is as follows: + +<screen><prompt>%</prompt> <userinput><command>kstart</command> <option>--ontop</option> <option>--alldesktops</option> <option>kcalc</option></userinput></screen> +</para> + +<para>Hopefully the effect this command is +obvious - the kcalc window will stay on top of all +the others and be visible on every virtual desktop. A feature that is +less obvious is that this command will work with any NET compliant +environment, not just &tde;.</para> + +<para>We can pass arguments to programs we invoke with &kstart; as normal, for +example: + +<screen><prompt>%</prompt> <userinput><command>kstart</command> <option>--skiptaskbar</option> <option>--desktop</option> 1 xmessage 'Hello World'</userinput></screen> + +</para> + +<para>This command displays <computeroutput>Hello +World</computeroutput> with <application>xmessage</application> and +ensures that the window will be shown on the first virtual desktop and +will be omitted from the taskbar. The fact that this program is +written using the Xt toolkit rather than being a native &tde; +application does not cause any problem for +&kstart;. Hopefully this illustrates how +&kstart; can be used to integrate foreign +applications into your &tde; desktop.</para> +</sect3> + +<sect3 id="special-window-settings"> +<title>Other Special Window Settings</title> +<para>While you can use &kstart; to assign particular window settings, &tde; also allows you to alter these — as well as other similar settings — from the program window itself. Simply select the left-most button in the window titlebar (or press <keycombo action="simul">&Alt;<keycap>F3</keycap></keycombo> after the window is focused), and then go to <menuchoice><guisubmenu>Advanced</guisubmenu><guimenuitem>Special Window Settings...</guimenuitem></menuchoice>. As you can see, from here you change various things from its geometry upon startup, to whether it should have a border or not.</para> +</sect3> + +<sect3 id="system-tray"> + +<title>The System Tray</title> + +<para>Now that we know how to customize the decoration of a window +let's take a look at another aspect of the desktop: the system +tray. The system tray is an area in which an application can display a +small window. It is used to display status information or provide +quick access to commands. A window that has an item in the system tray +usually disappears from the task manager when minimised with the tray +icon providing a replacement. Normally tray icons are specifically +developed as part of an application, but as with window decorations, +&tde; provides a tool for changing this: +<application>ksystraycmd</application>.</para> + +<para>To begin with, we'll take the standard application &kcalc; and turn +it into a system tray application. This is acheived with one simple +command: +<screen><prompt>%</prompt> <userinput><command>ksystraycmd</command> <option>--title</option> 'kcalc' kcalc</userinput></screen> + +</para> + +<para>The icon shown in the tray is the one specified in the window +hints and will be updated if the icon changes. The window title is +shown as a tooltip if you hold the mouse pointer over the icon. +<application>ksystraycmd</application> follows standard &tde; +behaviour so the target window can be shown and hidden by clicking the +tray icon, and a standard context menu is available.</para> + +<screenshot> <mediaobject> <imageobject><imagedata +fileref="kcalc-systray.png"></imagedata></imageobject> +</mediaobject></screenshot> +</sect3> + +<sect3 id="more-complex-uses-of-ksystraycmd"> + +<title>More Complex Uses of +<application>ksystraycmd</application></title> + +<para>To illustrate the other features of +<application>ksystraycmd</application>, we'll use a more complicated example: a &konsole; window tracking the +<filename>.xsession-errors</filename> file (this is the log file that records what's +happening on your desktop). To begin with, we'll simply look at how +we can view this: +<screen><prompt>%</prompt> <userinput><command>konsole</command> <option>--icon</option> log <option>--caption</option> 'X Log' \ +<option>--nomenubar</option> <option>--notabbar</option> <option>--noframe</option> \ +<option>-e</option> tail -f ~/.xsession-errors</userinput></screen> +</para> + + <para>The <option>--caption</option> and <option>--icon</option> +arguments are provided as standard by &tde; applications. You can get +a full list of these global options by running an application with the +<option>--help-kde</option> and <option>--help-qt</option> +parameters. Here we give our &konsole; window the title 'X Log' and +the icon <quote>log</quote>. You can use these options with any &tde; application and +as mentioned above, <application>ksystraycmd</application> takes account of these when creating +the tray icon. The <option>-e</option> argument is specific to &konsole; and tells it +to run the <command>less</command> command. Despite its complexity, we can easily move +this window into the tray with <application>ksystraycmd</application>: + +<screen><prompt>%</prompt> <userinput><command>ksystraycmd</command> <option>--hidden</option> <option>--title</option> 'X Log' \ +konsole --icon log --caption 'XLog' \ +--nomenubar --notabbar --noframe \ +-e tail -f .xsession-errors</userinput></screen> +</para> + + <para>In addition to being the +most complex command we've used, this example demonstrates the +<option>--hidden</option> option which starts the command with only the system tray +icon visible. This example achieves our aim of providing quick access +to the log file, but we can do things a little more efficiently if we +only run the konsole process when it is visible. The command we use +is +<screen><prompt>%</prompt> <userinput><command>ksystraycmd</command> <option>--startonshow</option> \ + --<option>icon</option> log <option>--tooltip</option> 'X Log' \ +konsole --icon log --caption 'X Log' \ +--nomenubar --notabbar --noframe \ +-e tail -f ~/.xsession-errors</userinput></screen> +</para> + +<para>The addition of the <option>--startonshow</option> parameter tells +<application>ksystraycmd</application> to start with only the tray +icon visible (like the <option>--hidden</option> parameter), and to wait until the user +activates the tray icon before running the target command. We've also +used the <option>--quitonhide</option> parameter which tells <application>ksystraycmd</application> to terminate +the target app whenever its window is hidden. Using both these +parameters ensures that our &konsole; tray icon doesn't waste resources +when we aren't using it. Creating and destroying the target window as +we do here prevents the standard icon and title handling of +<application>ksystraycmd</application> from working, so we now need to +specify the initial icon and tooltip explicitly +too.</para> +</sect3> + +<sect3 id="improving-reliability"> + +<title>Improving Reliability</title> + +<para>In all of our previous examples we've relied on +&kstart; and +<application>ksystraycmd</application> to figure out which window we +want to affect, and unless we say otherwise, they assume that the first +window to appear is the one we want. This policy is usually OK because +we are starting the application at the same time, but it can fail +badly when lots of windows are appearing (such as when you log on). To +make our commands more robust we can use the +<option>--window</option> parameter. This specifies the title +of the target window. The following example uses the <option>--window</option> parameter +to ensure that a particular konsole window is affected: + +<screen><prompt>%</prompt> <userinput><command>kstart</command> <option>--iconify</option> <option>--window</option> 'kstart_me' konsole --caption 'kstart_me' -e tail -f ~/.xsession-errors</userinput></screen> + +</para> + +<para>Here we've used the tried and tested technique of specifying a +title for both &kstart; and the target application. This is generally +the best way to use &kstart; and <application>ksystraycmd</application>. The <option>--window</option> argument is +supported by both &kstart; and <option>ksystraycmd</option> and can be regular expression +(⪚ <quote>window[0-9]</quote>) as well as a particular title.
