gtk2/TODO

TODO BEFORE GTK 1.0
-------------------

Bugs:
 * pasting into a GtkEntry that already has a very long string,
   causes the app to hang.
 
 * Vertical scrollbar: the expose event looks hosed and is causing 
   quite a bit of flickering
   Actually this affects both scrollbar implementation, you can best
   tell if you run the application with --sync (timj)

 * signal parameters don't seem to get refreshed on recursive invokations
   of GTK_NO_RECURSE signals, which causes the restarted emissions to loose
   their actual point, i.e. parameter changes on the restarted emission,
   needs further investigation.

 * Widget redrawing when the window resizes sometimes messes up.
   GtkLabels sometimes redraw without clearing up the underlying background on
   window resizes.
 
 * Are there still some GtkCList changes outstanding? (Jay Painter)
   GtkCList is derived from GtkContainer but doesn't implement the
   need_resize, focus, add and remove methods from containers.
   it should at least issue a warning upon invokation of not supported
   member functions.

 * GtkTree and GtkList should express in their *_add implementations,
   that they expect GtkListItems/GtkTreeItems as children. Similar
   things might apply to other containers.

 * delay dnd settings to take effect once a widget is realized, this is
   to avoid force realizations. i think this goes along with owens dnd
   changes?
    -timj
   The way DND data types are set in GtkWidget really needs to be fixed.
   This is pretty high on my priority list, and I'll get to it as soon as
   the column list widget is done.  The correct way dnd data needs to be set
   is to have a additional keyed data type with GtkWidget, which is applied to
   the widget's window upon realize.
   There also needs to be a way to set dnd-data on widget windows which are
   not the main window (for widgets that create more than one window).
    -Jay Painter
   DnD seems to work for me, but yes, there needs to be some sort of
   gtk_widget layer that makes it easier... Also, adding support for drop
   zones might be nice.
    -Elliot
   This one is reproducabel for me:
   testgtk --sync
   popup colorselection
   drag/drop works
   start up preview color
   drag works but not dropping
   end preview color
   drag/drop works
   start up prewiev color
   segfault in malloc
    -timj

 * Change bitfields to guints from enums for C++ ?

 * Force paned window handle to be kept on screen

Additions:
 * widgets which are redrawn because of a gtk_widget_draw(,NULL) should
   be removed from the redraw queue.
   
 * GScanner: it might be good to ues stdio and getch() instead of 1-character
   reads. so one can take advantage of buffering. Currently each read() takes
   a separate syscall.
   
 * implement gtk_default_draw_oval
 
 * Lists should scroll to center the recently selected item if it isn't
   visible.

 * enforce invariants on *_RESIZE* and *_REDRAW* flags.

 * asure that child widgets are really get gtk_widget_destroy()ed in their
   parents destroy handler, and not just unparented or somesuch.

 * GtkToolTips:
   allocate GtkTooltipsData from memchunks
   look into incorporation of outdated/gtk-dairiki-971208-[01].patch.gz
                          
 * Make widget attributes configurable after the widget is created (timj).

 * Change gtk_widget_propagate_default_style() mechanism to
   void gtk_rc_string_export (const gchar *rc_additions,
                              gboolean     override_rc_styles);

 * Configure events for windows that no longer exist fail in
   XTranslateCoordinates
 
TODO AFTER GTK 1.0
------------------

 * Make all widget attributes configurable after the widget is created (timj).

 * Seperate GtkObject and signaling system from Gdk dependancies?
  
 * move *_input_add (wrappers for select(2)) mechanism into glib.

 * Make sure a widget added to a list is a list item and a widget added
   to a menu is a menu item, etc. GTK_BASIC was a first attempt at this,
   but it fails with subsequent container_add()s. maybe have another
   GTK_PARENT_BASIC (similar to GTK_PARENT_SENSITIVE) flag, to prevent
   tree iterations upon every container addition.

 * gdk_expose_compress: ala-Xt, this would really help for opaque moves and
   such

 * Entry should have a password mode (and it should show stars
   for user feedback).

 * More dialogs: Print, GtkFontSelector, maybe others...

 * Multiple document interface (MDI)?

 * Support another widget style? Should be possible using GtkStyle's, but
   there may be some work needed to remove any style dependencies in widget
   code. Maybe GtkStyle's should have 'draw_push_button', 'draw_check_button',
   etc, functions to draw the various widgets.
   This will be covered by upcoming themability, raster is working on it.
 
 * make the gtk_main callbacks consistent in their add/remove behaviour.
 
 * More work on Documentation

 * Check return values on all calls to XIC[Get/Set]Values

 * Rewrite the interface to the i18n stuff so GTK widgets don't need to
   retrieve X values, and so they don't have to know the value of the
   XNxxx character constants.

 * The "-geometry" option should be supported

  - Having gdk_init() parse the geometry option. (putting it into
    GDK means you can use XParseGeometry() without wrapping it)

  - Add a call gdk_get_geometry() that retrieves the results 
    in a form like that returned by XParseGeometry()

  - The application then can modify the results (as would gemvt)
    then call a routine gtk_window_set_geometry() on whatever
    it considers to be its main window.

  - Then in some manner GtkWindow takes that into account when
    setting its hints. (Probably it uses the size and position
    as the current uposition and usize, and modulates that
    be the equivalents of the X flags

     XValue, YValue, WidthValue, HeightValue, XNegative, or YNegative

    ( You'd have to extend gdk_window_set_hints to accept the
      window gravity option to get it right. )

 * Text/Edit widget: (some of these might be bugs that should be fixed now)

  Bugs:

  - In Entry and Text widget, you can ungrab while still
    dragging by pressing button-1, pressing button 3, releaseing 3,
    then releasing 1.

  - When selecting on a Text or Entry widget, the selection isn't
    claimed until you release the button, and that shows by the
    color of the selection. (Which is the real problem - it probably
    is OK/better to delay claiming the selection) [fixed]

  - Related to the above, when you Shift/arrow to select text, the
    selected text doesn't show that you have the selection immediately.

  - Selecting an entire line with triple-click doesn't work right - 
    it should select the wrapped portion too.

  - Selecting an entire line should probably select the newline as
    well, so when the selection is cut/deleted, the newline goes
    along.

  - Inserting text in a different property - problems? Shouldn't
    split the last position off in any case.

  - Do something about the bg pixmap situation. (It will produce
    garbage when editing is enabled)

  - "Copy" removes selection
 
  Improvements:

  - Finish making the key bindings consistent between the Entry
    and Text widgets

  - Unify the key binding support in some fashion between the
    two widgets (???)

  - When inserting or deleting large chunks of text, do a freeze/thaw
    automatically, to avoid scrolling around for ever on screen.

  - Jump scroll on large insertions/deletions

  - Prune the line start cache. But since it is only 68 bytes
    per line, and it is a lot faster when lines are in the cache,
    it may be better not to, at least for now.

  - Show the non-editable state by changing colors. (Use the
    style entries for insensitive?)

  - Multibyte support for the Text widget.

  - Unicode support to do the multi-byte right.

  - Support an .inputrc. (The readline one doesn't really work,
    unless it is extended because it can't represent X keysyms,
    just terminal type input)

  - A vi mode

  - Word wrap, instead of line folding. (Should the continuation
    characters be shown?)

  - Horizontal scrolling

  - Disable pasting compound text

  - When showing background pixmap (not editable) actually set
    the background pixmap as the windows bg pixmap, to improve
    appearance on exposes. But this would require using another
    window to get the origins.

 ? Allow moving the separator for paned widgets by dragging 
   it directly instead of using the handle. 

 ? Mark public use of gtk_tree_remove_item as deprecated - it should be used
   as:
         gtk_container_remove (GTK_CONTAINER(tree), widget);

 * Standardize that all strings should be passed as gchar *, not 
   guchar *. But what about non-string data? (gdk_property_change,
   gtk_selection_data_set) X makes these sort of things guchar...

 * Check into XAddConnectionWatch - is this needed for XIM?

 * Places where a _full variant is needed:

    gtk_clist_set_row_data
    gtk_init_add
    gtk_menu_popup
    gtk_toolbar_prepend_element
    gtk_toolbar_insert_element
    gtk_widget_dnd_data_set (should be guchar * with a copy?
                             shouldn't be there at all...)
    ??? GtkDrawingarea.draw_data
 
 * gtk_rc_add_[name/class]_style are broken for bg pixmaps, because
   styles are broken for bg pixmaps, and RC styles only hack around
   that.
