Package: gtk

GBoxed gtk:css-section

Declaration

(glib:define-gboxed-opaque css-section "GtkCssSection"
  :export t
  :type-initializer "gtk_css_section_get_type"
  :alloc (error "GtkCssSection cannot be created from the Lisp side"))

Details

Defines a part of a CSS document. Because sections are nested into one another, you can use the gtk:css-section-parent function to get the containing region.

Examples

(g:signal-connect provider "parsing-error"
        (lambda (provider section err)
          (declare (ignore provider err))
          (let* ((startloc (gtk:css-section-start-location section))
                 (start (gtk:text-buffer-iter-at-line-index
                                text
                                (gtk:css-location-lines startloc)
                                (gtk:css-location-line-bytes startloc)))
                 (endloc (gtk:css-section-end-location section))
                 (end (gtk:text-buffer-iter-at-line-index
                              text
                              (gtk:css-location-lines endloc)
                              (gtk:css-location-line-bytes endloc))))
            (gtk:text-buffer-apply-tag text "error" start end)
            gdk:+event-stop+)))
