-============================
-
-This document describes some tips and rules for porting UI code
-written with GTK+ and C to GtkBuilder + Glade.
-
-
-
-Overview
---------
-
-1. Locate code to port
-2. Start a new UI file with Glade
-3. Systematically convert the code to Glade
-4. Construct UI with GtkBuilder and do setup of widgets
-5. Add .ui file to build system
-6. Test
-7. Enjoy less UI C code
-8. Troubleshooting
-
-
-
-Locate code to port
--------------------
-
-Look for code that looks like this:
-
- // Create a widget and add to hierarchy
- widget = gtk_some_widget_new (some_params);
- gtk_some_container_add (container, widget)
- gtk_widget_show (widget);
-
- // Repeat...
-
-
-
-Start a new UI file with Glade
-------------------------------
-
-Start glade-3. Pick project file format 'GtkBuilder' (not
-'Libglade'). For maximum compatibility, use the minimal gtk+ catalog
-possible. The file extension shall be .ui. Look where other files are
-put and how they are named.
-
-
-
-Systematically convert the code to Glade
-----------------------------------------
-
-Go through the code that you want to convert line by line and add
-widgets in Glade as you remove lines. For example:
-
- main_vbox = gtk_vbox_new (FALSE, 12);
- gtk_container_set_border_width (GTK_CONTAINER (main_vbox), 12);
- gtk_container_add (GTK_CONTAINER (dialog_vbox),
- main_vbox);
- gtk_widget_show (main_vbox);
-
-is replaced by
-
-
-
-in the UI declaration produced by Glade.
-
-
-
-Construct UI with GtkBuilder and do setup of widgets
-----------------------------------------------------
-
-The code to construct the UI will look something like this:
-
- builder = gtk_builder_new ();
- ui_file = g_build_filename (gimp_data_directory (),
- "ui/plug-ins/plug-in-file-gif-save.ui",
- NULL);
- if (! gtk_builder_add_from_file (builder, ui_file, &error))
- g_printerr (_("Error loading UI file '%s':\n%s"),
- ui_file, error ? error->message : "???");
- g_free (ui_file);
-
-and then you do setup of widgets using:
-
- widget = GTK_WIDGET (gtk_builder_get_object (builder, "widget-name"));
- gtk_widget_whatever (widget, params);
-
-Look in plug-ins/common/file-gif-save.c for helper function you can
-use for some tricky widgets.
-
-
-
-Add .ui file to build system
-----------------------------
-
-The UI declarations are installed as data files, see
-plug-ins/ui/Makefile.am for example, and it needs to be added to
-POTFILES.in for translations.
-
-
-
-Test
-----
-
-When you're done, make sure
-
-1. that translations still work. If they don't, maybe you forgot to
-add the UI file to the relevant POTFILES.in or maybe you changed
-strings, for example by adding markup. In the latter case, use pango
-text styles instead of markup (use GKT+ 2.16 UI files).
-
-2. that mnemonics still work, in particular when the mnemonic is not
-on the widget to be activated. For e.g. labels you need to explicitly
-assign a widget that will be actiated when the label mnemonic is
-pressed.
-
-3. that the spacing and other layout detals are still correct.
-
-
-
-Enjoy less UI C code
---------------------
-
-Enjoy!
-
-
-
-Troubleshooting
----------------
-
-If your GtkComboBox doesn't draw any items it's probably because it
-doesn't have a cell renderer. Apparently there is no UI to add one in
-GLade-3, so add it manually in the UI file, see the GTK+ doc for
-GtkCellLayout; this is what you need to add:
