Ok, I need a way to change the "theme" of my app with different glyphs.
Say I could use DVD glyphs on the buttons or the next time there could be
book glyphs.  Next time there could be CD glyphs of video glyphs.  I also
have different size glyphs including 16, 24, 32, 40, and maybe 64.

 I already use imagelists but is there an easier way than to create an
imagelist for each size and each group of icons?  If there were 3 themes and
5 sizes that would be 15 imagelists.

Store images in a resource, is my suggestion.  You list the image file
names in a .rc file, then compile the rc file to a .res file. It's been
a while since I did this, but I believe it's as simple as the following:

{$R 'MyImages.res' 'MyImages.rc'}

During the project build/compile process, Delphi automatically compiles
the .rc file, finds the images referenced therein, and puts them into
the .res and the linker puts it all together.  (Check the help and/or
examples for syntax.)

In the project, call LoadFromResourceName specifying the resource (your
application or a DLL if that's where they are stored, and the reference
name of your image (named in your .rc file and not the actual filename).

By keeping different theme sets in different DLLs, you could simply
switch to a different DLL and reload all the images by the same name.
Then you or your customer could add new themes later.


Hope that helps,

If you are using VS, you can add an ImageList object to your app. You =
can add multiple images ot it and call them by their index # @ runtime =
and the UI will reflect it. I've only used them in Windows Forms =
project. I don't even know if that object is available in any other app =
type.
