What is the best way to get hold of the current colour theme and colours? I want to use the same colours.

   MD_REF needs to be set to the moneydance context

   currentTheme = MD_REF.getUI().getCurrentTheme()
   id = currentTheme.getThemeID()
   if currentTheme.isSystemDark() then xxx

   examples:
   RED:
   MD_REF.getUI().getColors().errorMessageForeground

   BLUE:
   MD_REF.getUI().getColors().defaultTextForeground

   Dark Green:
   MD_REF.getUI().getColors().budgetHealthyColor

   Refer:
   com.moneydance.apps.md.view.gui.MDColors

   Hope this helps? If not shout, with what else you need?

   Thanks Stuart, I have always had problems with getting the context. Once you have it you can navigate the data. How do you get the context?

   Found it, the FeatureContext passed is an Main object which contains the ui but this is null until you invoke the extension. Once invoked you can get hold of the UI and then get hold of the colors.

   There's a singleton for the MDColors class which you're welcome to use:
   'colors = com.moneydance.apps.md.view.gui.MDColors.getSingleton()'

   The colors object has all of the different colors in use as public members. If the color theme changes then those members are updated with the new values.

   Cheers,

   You can get to the colors by casting the context and ui to the appropriate class.

   The code is:
   

        com.moneydance.apps.md.controller.Main mdContext = (com.moneydance.apps.md.controller.Main) context;
           MoneydanceGUI ui = (MoneydanceGUI)mdContext.getUI();
           MDColors defaults = ui.getColors();
   

   This must be done after the extension is 'invoked'. The ui us null when the extension is intialized.

   If you use the MDColors.getSingleton() call you don't need the UI or even the extension context. In general you should access the colors when you are showing the UI, not during extension initialisation. The MDColors object will always be the same object, but the color properties will change as the app is running. So it's a good idea to get the colors at the point where you are creating the UI, not in the extension initialisation.

   Cheers,
   Sean

   Is there a listener for changing the theme/preferences so I know when the colours have changed?

   from com.moneydance.apps.md.controller import PreferencesListener

   Method preferencesUpdated()

    Within .preferencesUpdated() you can then do this...

    newThemeID = prefs.getSetting("gui.current_theme", ThemeInfo.DEFAULT_THEME_ID)
    if self.themeID and self.themeID != newThemeID:
       do something
