This is useful for including image files and other resourcesdirectly into your application rather than loading the data from externalfiles.<p> QEmbed can also generate uncompressed versions of images that can be includeddirectly into your application, thus avoiding both the external file and theneed to parse the image file format. This is useful for small images such asicons for which compression is not a great gain.<p> <h2> Usage</h2><a name="1"></a><p> <pre> qembed [ general-files ] [ --images image-files ]</pre> <p> <ul><li> <tt>general-files</tt><p> These files can be any type of file.<p> <li> <tt>--images image-files</tt><p> These files must be in image formats supported by Qt.</ul><p> <h2> Output</h2><a name="2"></a><p> The output from QEmbed is a C++ header file which you shouldinclude in a C++ source file. In the source file, you should make awrapper function that suits your application. Two functions areprovided; your wrapper function could just call one of these, oryou can implement your own. Here's a simple example of usage for eachof the supplied functions:<p> <h3> qembed_findImage()</h3><a name="2-1"></a><p> <pre> #include "generated_qembed_file.h" <a href="qimage.html">QImage</a> myFindImage(const char* name) { return qembed_findImage(name); }</pre> <p> Just call the generated function; <em>name</em> is the original imagefilename <b>without</b> the extension.<p> <h3> qembed_findData()<pre> #include "generated_qembed_file.h" <a href="qbytearray.html">QByteArray</a> myFindData(const char* name) { return qembed_findData(name); }</pre> </h3><a name="2-2"></a><p> Just call the generated function; <em>name</em> is the original filename<b>with</b> the extension<p> Alternatively, look at the output from QEmbed and write a functiontailored to your needs.<!-- eof --><p><address><hr><div align=center><table width=100% cellspacing=0 border=0><tr><td>Copyright © 2002 <a href="http://www.trolltech.com">Trolltech</a><td><a href="http://www.trolltech.com/trademarks.html">Trademarks</a><td align=right><div align=right>Qt version 3.0.5</div></table></div></address></body></html>⌨️ 快捷键说明
