Re: GTK+ modularization

["Mike Emmel" <mike emmel gmail com>]

Can I suggest considering a version designed for custom widgets.
And leave it to the embedded developer to selectivley pull in more widgets.

This would be GtkWindow GdkBin  GtkButton and a few more say text input.
basically a very simple toolkit.

After this if you want to use gtk custom widgets are probably the best answer
or bringing in a subset.

So first you would define this core base of widgets that are "must haves"
Then you need to group all the rest based on dependencies to allow
them to be selectively compiled in.
I'd not even include toolbars and menus for example in the base.

Here is my list of base classes

Windows

   GtkWindow - Toplevel which can contain other widgets

Display Widgets

   GtkImage - A widget displaying an image
   GtkLabel - A widget that displays a small to medium amount of text

Buttons and Toggles

   GtkButton - A widget that creates a signal when clicked on
   GtkCheckButton - Create widgets with a discrete toggle button
   GtkRadioButton - A choice from multiple check buttons
   GtkToggleButton - Create buttons which retain their state

   GtkEntry - A single line text entry field


Multiline Text Editor

   Text Widget Overview - Overview of GtkTextBuffer, GtkTextView, and friends

   GtkTextTag - A tag that can be applied to text in a GtkTextBuffer
   GtkTextTagTable - Collection of tags that can be used together
   GtkTextView - Widget that displays a GtkTextBuffer


Menus, Combo Box, Toolbar

   GtkComboBox - A widget used to choose from a list of items
   GtkComboBoxEntry - A text entry field with a dropdown list

   GtkMenuBar - A subclass widget for GtkMenuShell which holds
GtkMenuItem widgets
   GtkMenuItem - The widget used for item in menus

fixed coordinates

not have their own window
