<P>

Icons are bitmaps that may contain transparency information. Under X, icons are
|
|
usually created from XPM files, which may be loaded from a file or created from
|
|
data embedded in a C++ source file.<P>
|
|
|
|
Under Windows, icon files (extension .ico) may contain multiple icons for different sizes and colour
|
|
depths, and can be loaded from a file or loaded from the Windows resources compiled
|
|
into the executable.<P>
|
|
|
|
You can decide to use only XPMs on Windows and Unix, or you could use XPMs on Unix and
|
|
Windows icons under Windows -- the latter will require some #ifdefs in your code or use of the wxICON macro.<P>
|
|
|
|
If you are using a compiler such as Borland C++, Visual C++ or Watcom C++, you
|
|
can use the provided icon editor. However, if using Cygwin or Mingw32, there
|
|
is no icon editor so you must obtain one separately, such as <a href="http://hotfiles.zdnet.com/cgi-bin/texis/swlib/hotfiles/info.html?fcode=00165P">IconEdit32</a>.<P>
|
|
|
|
To convert from XPM to BMP (which can be loaded or pasted into an icon editor to save as an ICO file),
|
|
you can use Vadim Zeitlin's <a href="ftp://biolpc22.york.ac.uk/pub/support/xpm2bmp.exe">xpm2bmp.exe</a> utility.
|
|
To convert from BMP to XPM, you can use <a href="ftp://biolpc22.york.ac.uk/pub/support/bmp2xpm.exe">bmp2xpm.exe</a>
|
|
which is actually the old wxWidgets 1.68 utility, xpmshow. You will have to edit the resulting
|
|
file since the full path is used as the variable name, plus you may wish to specify a transparent colour e.g.:<P>
|
|
|
|
<pre>
|
|
" s None c None",
|
|
</pre>
|
|
|
|
This will indicate that the space character will be taken as the transparent colour throughout the image.<P>
