25 | Icons are bitmaps that may contain transparency information. Under X, icons are | |
26 | usually created from XPM files, which may be loaded from a file or created from | |
27 | data embedded in a C++ source file.<P> | |
28 | ||
29 | Under Windows, icon files (extension .ico) may contain multiple icons for different sizes and colour | |
30 | depths, and can be loaded from a file or loaded from the Windows resources compiled | |
31 | into the executable.<P> | |
32 | ||
33 | You can decide to use only XPMs on Windows and Unix, or you could use XPMs on Unix and | |
34 | Windows icons under Windows -- the latter will require some #idefs in your code or use of the wxICON macro.<P> | |
35 | ||
36 | If you are using a compiler such as Borland C++, Visual C++ or Watcom C++, you | |
37 | can use the provided icon editor. However, if using Cygwin or Mingw32, there | |
38 | 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> | |
39 | ||
40 | To convert from XPM to BMP (which can be loaded or pasted into an icon editor to save as an ICO file), | |
41 | you can use Vadim Zeitlin's <a href="ftp://www.remstar.com/pub/wxwin/support/xpm2bmp.exe">xpm2bmp.exe</a> utility. | |
42 | To convert from BMP to XPM, you can use <a href="ftp://www.remstar.com/pub/wxwin/support/bmp2xpm.exe">bmp2xpm.exe</a> | |
43 | which is actually the old wxWindows 1.68 utility, xpmshow. You will have to edit the resulting | |
44 | file since the full path is used as the variable name, plus you may wish to specify a transparent colour e.g.:<P> | |
45 | ||
46 | <pre> | |
47 | " s None c None", | |
48 | </pre> | |
49 | ||
50 | This will indicate that the space character will be taken as the transparent colour throughout the image.<P> | |
