Re: How to get Colors?

[The Devils Jester <thedevilsjester gmail com>]

I am aware of the dynamics of GTK, but the need to render custom widgets to use a similar color palette to the current theme is a real one that does not seem to have an elegant solution.  I know that as desktops get increasingly more gradient/texture based, the idea of a single defining background color gets more and more quaint, but this doesnt eliminate the need.

In the same vein, of colors, can someone explain what I am doing wrong when: gtk_style_context_get_background_color(context, GTK_STATE_FLAG_NORMAL, &bg_n); gives me nothing but black for the same widget that gtk_widget_get_style gives me the (expected) rgb (214,214,214) ?

Your mistake is imagining that there are "system colors" and that you can do "custom rendering" that will use them.

GTK is largely designed around a Linux model in which the ability of the user to dynamically alter the appearance of applications (and the desktop) is taken more seriously than on other platforms. Colors are left up to "themes" which the user may change at any time. Some themes may, internally, define some kind of color palette, but they do not expose this to applications. You're expected to allow the theme to do its job with rendering.

I am trying to get general GTK system colors for use in custom rendering operations.  In MSW, I would get these colors through a function like GetSysColor, but GTK does not appear to have such a function.

The only way that comes to mind, to get a bunch of common system colors, is to create a bunch of widgets (one of each type that has a color I need), parent said widget, and make sure its realized, using gtk_style_context_get_color.  This seems like an awful lot of overhead (and a bit overkill) just to get some colors.  Am I missing some more direct method?

I am using GTK3.
