Sure.
They can be set using the API's only:
app->setBorderColor(FXRGB(255,0,0)); // Set to red, for example
app->setBaseColor((FXRGB(0,255,0)); // Set to blue
...
...
app->setSelMenuBackColor(FXRGB(244,244,244)); // Off-white
Now, normally the order of things is as follows:
1) FXApp's constructor set things to stock values.
2) FXApp::init() populates colors from WIN32 Registry (on Windows only)
3) FXApp::init() then reads FOX registry and overwrites colors again;
note, if no values are set in FOX registry then we keep the last
value.
4) We construct a MainWindow; all widgets constructed take on colors
copied from FXApp.
5) We then create the tree and run the app.
So, the best opportunity to change color programmatically is between steps (3)
and (4). You can change colors later, but then you'd have to change them
individually for each widget. This may be a lot of work, depending on how
many widgets were created. The FOX Calculator program uses this approach
since it wants different buttons to have different colors.
