Re: [fltk.general] Changing an Fl_Menu_Bar item colors
True; this would be quite challenging to achieve as Fl_Menu_Item provides only plain draw(). For the similar reason (to add icons support inside menu items) I had to literally 'fork' the whole menu hierarchy :S Sanel On Thu, Jan 31, 2013 at 05:50:21AM -0800, MacArthur, Ian (Selex ES, UK) wrote: Thanks for the reply.

Here's a test - is this any better? If you send a message that uses characters from certain character sets in the message body. Messages that use character sets from the following code pages are encoded as Base64 messages when they are sent from an Exchange 2000 computer: Shift-JIS EUC-KR ISO-2202-JP BIG5 ISO-2202-KR GB18030 GB2312 Yup - though I don't use any CJK language normally, so I don't think that can be it. I do wonder if it is struggling with something else that is getting encoded as UTF-8 in my posts though? That might do it I guess, if it is 7-bit cleanness that is the issue here?

Re: [fltk.general] Changing an Fl_Menu_Bar item colors
Thanks for the reply. This code works well for changing the text
foreground color.
However I also need to change the background color (the gray box behind
the text).
Any ideas how to change the background color in an Fl_Menu_Bar item?
Thanks,

Here is example:

Fl_Menu_Bar *bar = (Fl_Menu_Bar*)w;
if(!bar-mvalue()) return;
Fl_Menu_Item *self = (Fl_Menu_Item*)bar-mvalue();

// your Fl_Menu_Item table:

{0}

Hi,
I had a similar requirement some time ago, so workaround like this
helped me. There are hidden gems here and there... :)

Re: [fltk.general] Changing an Fl_Menu_Bar item colors
I have an Fl_Menu_Bar with a few added items that have the FL_MENU_TOGGLE property. This adds checkboxes to the menu. I need to change the visual indication that each menu item has been clicked from the checkbox to toggling menu item foreground (text) and background colors. Obviously I could eliminate the FL_MENU_TOGGLE property if that'd help. I don't know... for historical reasons, the menu entries in the fltk-1.x menus aren't proper widgets in the usual fltk sense, so changing their behaviour and appearance is a pain. Though I think it can be - but I don't have any example code here; perhaps others have something? (I think fltk3, and indeed fltk2, are attempting to address that menu discrepancy and make menu items more normal so this problem might go away. Eventually...)
