I merely react to this grossly out of context (so please forgive me), but I just can't resist... Did you really mean what I read you to mean? Many (and I mean MANY) people can't even _see_ red (but can see colors that somewhat resemble it), so they _have_ to change it... others don't like the color red because of psychic problems (after witnessing accidents, ...) (especially big red areas on buttons that look like a puddle of blood that flows around until it reaches some obstacle). Others don't like it because of other reasons. Low-color displays (over modem lines etc) have 256 color limitations, which makes hardcoded color values a PITA, because they eat up palette entries for _all_ applications and in the end you can't read a thing. (not mentioning black-and-white displays here because they got kind of rare) http://vision.about.com/od/commonvisiondefects/ss/colorblindimage_3.htm Let's not go back to the dark old times where the programmer decided what was good and the user needed to eat it, whether he wants to or not. Also, nowadays, we usually do have some processor cycles to spare for doing the right thing. gtk does the right thing by letting the programmer register "style properties" for a widget class. These names can then be used in themes and gtk will assign the theme color to the style property of the widgets of that class on runtime. I know that it usually depends on the target audience whether it's ok to take shortcuts like hardcoding colors (if your program is to be used by an internal group of 5 people, new people never enter, and none of them has color blindness, sure, hardcode red all you like). _But_ when designing a framework, that is the wrong way to take because they affect all the users there are. sigh. cheers, Danny _________________________________________________________________ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
