<title>Add backing store support</title>
|
|
<description>
|
|
<p>
|
|
GTK+'s drawing model involves clearing to a background, and
|
|
then drawing widgets on top of this. Without having
|
|
backing-store support, this results in flickering in various
|
|
situations. Backing store cannot be added widget-by-widget,
|
|
because the drawing in a particular window is not confined
|
|
to a single widget. Instead it needs to be added per GDK
|
|
window.
|
|
</p>
|
|
<p>
|
|
The way this is done is by having
|
|
<tt>gdk_window_begin_paint()</tt>
|
|
and <tt>gdk_window_end_paint()</tt> functions that
|
|
redirect all drawing to a particular window to an offscreen
|
|
pixmap, and then copy that offscreen pixmap back onto the
|
|
screen when the paint operation is done. The implementation
|
|
of this is mostly complete in the <tt>gtk-no-flicker</tt> branch of
|
|
GTK+.

<title>32 Bit Coordinates</title>

<description>

<p>
|
|
GTK+-1.2 and earlier share X's limitation on the
|
|
size of coordinates and restrict all dimensions
|
|
to 16 bit quantities. By clever use of X it is
|
|
possible to lift this restriction and present a
|
|
full 32-bit space to the user.

<title>Switch to using UTF-8</title>
|
|
<description>
|
|
<p>
|
|
This is closely related to Pango integration. Pango deals
|
|
with all strings in terms of UTF-8; by switching GTK+ over
|
|
to UTF-8 we make it considerably simpler for developers to
|
|
support multiple languages properly while still retaining
|
|
a large degree of compatiblity with existing programs.
|
|
</p>
|
|
<p>
|
|
Some work has already been done on this as part of the Win32
|
|
port, since the Win32 port is currently using UTF-8 for all
|
|
strings. In general, this should be an easy job; the hardest
|
|
parts are places like GtkFileSelection, cut and paste, and
|
|
input method support where there is interaction between GTK+
|
|
and the operating system.

<title>Rewrite Input Method Support</title>
|
|
<description>
|
|
<p>
|
|
Current support for Input Methods is done via XIM, with
|
|
supported styles being over-the-spot and the root-window
|
|
styles. However, the over-the-spot style is not going to
|
|
work well with the Pango integration, since it relies on the
|
|
text rendering in the program being done in the standard
|
|
Xlib style, so it will be necessary to also support
|
|
on-the-spot input. On-the-spot input is done by supplying a
|
|
set of callbacks that are invoked by the input methods.
|
|
</p>
|
|
<p>
|
|
While adding the above support, it may be desirable to
|
|
generalize the input-method support to the point where

The GTK+ object system is already in use in quite a few different

to have the object system separated from the GUI portions

<title>Allow argument customization</title>

<p>
|
|
Many types of object arguments (expander style in the CList,

|
default padding in button boxes, etc), conceptually go with
|
|
the theme, or as user preferences; they should not be set by
|
|
a particular program.

There needs to be a mechanism for themes to be able to

<title>Allow global customization</title>
|
|
<description>
|
|
<p>
|
|
There are a number of global parameters in GTK+ and GDK that should be
|
|
customizable by the user, such as the double-click timeout,
|
|
or whether widgets should be backing-stored by default.
|
|
</p>
|
|
<p>
|
|
If we had argument customization from an RC file, it might
|
|
be possible to do this simply with a global object with
|
|
arguments for the various global parameters that was
|
|
customized in the same fashion as object arguments.

The title of a frame should simply be another child widget
|

which, by default, holds a label widget. This will important

with Pango where proper text behavior will be more complex to

implement, but is also useful for certain user-interface

designs. (It can be useful, for example, to put a checkbutton

in that slot.)

<title>Replace GtkText Widget</title>
|
|
<description>
|
|
<p>
|
|
The GtkText widget is badly in need of replacement, since it is
|
|
buggy and insufficiently feature rich. There are a number
|
|
of possible candidates for a replacement, with the most
|
|
promising at the current time being Havoc Pennington's
|
|
(hp@redhat.com) port of the Tk Text widget.
|
|
</p>
|
|
<p>
|
|
As part of this job it will be necessary to add
|
|
<a href="http://www.pango.org">Pango</a> support to the
|
|
replacement. The structure of the Tk text widget port seems
|
|
suited to this as it works paragraph-by-paragraph, and
|
|
Pango works at a sub-paragraph scale.

<title>Add unified set of List/Tree/Grid widgets</title>
|
|
<description>
|
|
<p>
|
|
Currently, GTK+ has a large number of list and tree widgets
|
|
(GtkList, GtkTree, GtkCList, GtkCTree), non of which are
|
|
ideal. The GtkList and GtkTree widgets perform badly on large
|
|
sets. (GtkTree widget is also quite buggy.) GtkCList
|
|
and GtkCTree mostly solve the size problem, but are quite
|
|
complex and, despite that, not very flexible. They are limited to
|
|
displaying pixmaps and text, and neither support arbitrary
|
|
widgets nor custom drawing functions.
|
|
</p>
|
|
<p>
|
|
In addition to list and tree widgets, a closely related need
|
|
is a sheet widget that displays a (possibly editable) 2-D grid.
|
|
It would be desirable to have a complete set of widgets that
|
|
could be presented as the one-true-solution for these needs.
|
|
Model/View techniques could be used effectively to increase
|
|
both the simplicity and power of the interfaces.
