Gtk.TreeView：Python如何设置失去树形视图焦点时选择的背景色行

Question

I have trouble in python gtk.TreeView: when a row selected on treeview it has background Blue, and then after that I changed focus to another object (example textbox) then the row was selected changed color to gray. I don't want change it to gray, I want it to still Blue. Is there any help. Could you please help me? Thanks you,

Answer 1

I had the same problem. I've solved it with the CSS feature of gtk programs. the css to manage the selection of row is

GtkTreeView row:selected {\
        background: #f07746;\
        color: #ffffff;\
    }\

The background will override the gray effect when you lose the focus. In your program you can apply the custom style with

gtk_css_provider_load_from_data(provider, CSS, -1, NULL);

(C language, but I can imagine you can find the equivalent in python)

Hope it helps even if it is a late answer. Can
