<p><tt>kmap2qmap</tt> is a tool to generate keymaps for use on Embedded Linux. The source files have to be in standard Linux <tt>kmap</tt> format that is e.g. understood by the kernel's <tt>loadkeys</tt> command. This means you can use the following sources to generate <tt>qmap</tt> files:</p>
<ul>
<li>The <a href="http://lct.sourceforge.net/">Linux Console Tools (LCT)</a> project.</li>
<li><a href="http://www.x.org/">Xorg</a> X11 keymaps can be converted to the <tt>kmap</tt> format with the <tt>ckbcomp</tt> utility.</li>
<li>Since <tt>kmap</tt> files are plain text files, they can also be hand crafted.</li>
</ul>
<p>The generated <tt>qmap</tt> files are size optimized binary files.</p>
<p><tt>kmap2qmap</tt> is a command line program, that needs at least 2 files as parameters. The last one will be the generated <tt>.qmap</tt> file, while all the others will be parsed as input <tt>.kmap</tt> files. For example:</p>
<pre> kmap2qmap i386/qwertz/de-latin1-nodeadkeys.kmap include/compose.latin1.inc de-latin1-nodeadkeys.qmap</pre>
<p><tt>kmap2qmap</tt> does not support all the (pseudo) symbols that the Linux kernel supports. If you are converting a standard keymap you will get a lot of warnings for things like <tt>Show_Registers</tt>, <tt>Hex_A</tt>, etc.: you can safely ignore those.</p>
<p>It also doesn't support numeric symbols (e.g. <tt>keycode 1 = 4242</tt>, instead of <tt>keycode 1 = colon</tt>), since these are deprecated and can change from one kernel version to the other.</p>
<p>On the other hand, <tt>kmap2qmap</tt> supports one additional, Qt specific, symbol: <tt>QtZap</tt>. The built-in US keymap has that symbol mapped tp <tt>Ctrl+Alt+Backspace</tt> and it serves as a shortcut to kill your QWS server (similiar to the X11 server).</p>
