GResource

Following the GResource section, we'll make use of GResource to quickly bundle our assets in the app:

data/dev.geopjr.tinystats.gresource.xml

<?xml version="1.0" encoding="UTF-8"?>
<gresources>
  <gresource prefix="/dev/geopjr/tinystats">
    <file compressed="true">css/style.css</file>
    <file compressed="true" preprocess="xml-stripblanks">icons/dev.geopjr.tinystats.svg</file>
    <file compressed="true" preprocess="xml-stripblanks">ui/app.ui</file>
  </gresource>
</gresources>

Code

src/modules/prerequisites.cr

We no longer need the UI and CSS global variables, so we can go ahead and comment them out (or remove them) while loading the gresource:

# UI         = {{read_file("./data/ui/app.ui")}}
# CSS_STRING = {{read_file("./data/css/style.css")}}

Gio.register_resource("data/dev.geopjr.tinystats.gresource.xml", "data")

src/tiny-stats.cr

We can now load the ui file from the resource:

B_UI = Gtk::Builder.new_from_resource("/dev/geopjr/tinystats/ui/app.ui")

src/modules/views/main.cr

We can load our CSS from the GResource too:

def startup(app : Gtk::Application)
    CSS.load_from_resource("/dev/geopjr/tinystats/css/style.css")
end
