Re: How to change GTK+3 label color dynamically

Thanks! In some containers we can't change color of label? I have labels inside GtkLayout, and don't change color with Css but other labels out of this layout change. Why don't works? I do this dynamically but don't works too: GtkCssProvider *css_provider = gtk_css_provider_new();

You are right. I don't know why don't works before, because I had already tested and doesn't work... BU apparently now works with gdk_screen_get_default(); THanks for your help. On 16-03-2017 14:07, Tilo Villwock wrote: > Am Donnerstag, den 16.03.2017, 13:50 + schrieb Rúben Rodrigues: >>

No! This is the ID: https://ibin.co/3FlPSBGuokBB.png and this is the widget name https://ibin.co/3FlPnPaDN7Zl.png that i used in css provider. This is not the problem because in start of the program i change the label to other color to understand if css provider is working. And works, but when

Re: How to change GTK+3 label color dynamically

You keep using an id in the selector, but you never show how you set the id on the widget. I suspect you think the buildable ID you use with GtkBuilder is also the ID used when theming — which is definitely not the case. You will need gtk_widget_set_name(), instead. Of course, that comes with its
