gtk是linux一款强大的夸平台的图形化开发工具

	  optimized for common code path.

	* gtk/gtkpreview.c: added a few extra checks for the visual
 	(gtk-draco-980305-0.patch.gz).

	* gdk/gdk.c (gdk_signal): abort() on a signal if G_ENABLE_DEBUG
 	  is defined, so we dump core (gtk-draco-980305-0.patch.gz).

Sat Mar  7 13:00:00 1998  The Rasterman <[e-mail]>

	* gdk/gdkwindow.c (gdk_window_xid_at_coords),(gdk_window_xid_at):
	  added these two calls, gdk_window_xid_at_coords beign the one
	  to actually call to look up the current X Window ID at a particular
	  x,y co-ordinate onscreen accounting for a list of windows to be 
	  excluded from this search. Useful for DND support.
	* gdk/gdkprivate.h added in above function calls.

Sat Mar  7 01:07:24 1998  Owen Taylor  <[e-mail]>

	* gtk/gtkrange.c (gtk_range_expose): Fixed the vscrollbar
	  flickering problem, by checking the area on expose events.
	  (There was a hscrollbar flickering problem as well, it
	   just wasn't very noticeable)

Fri Mar  6 21:30:05 1998  Owen Taylor  <[e-mail]>

	* gtk/gtkeditable.c: Disallow pasting into non-editable
	  widgets.

	* gtk/gtktext.[ch]: 

	  -Added scrolling when dragging the selection
	   paste the top/bottom.

	  -Fix some of the problems with displaying the selection
	   state before mouse release.

	  -Disallow pasting into non-editable widgets

	  -Fixed segfault when changing window size

	  -Update the cursor correctly when switching between
	   editable and non-editable

	* testgtk.c: Added a toggle button for editability for
	  the text widget. 

Fri Mar  6 14:47:33 PST 1998 Shawn T. Amundson <[e-mail]>

        * Applied gtk-matsu-980205-0 (oops, should be 980305)
	  gdk/gdkinputcommon.h: return NULL if device is not ready
          gtk/gtkwindow.c: check for GDK_ISO_Left_Tab

Fri Mar  6 13:17:58 1998  Marc Ewing  <marc@.redhat.com>

	* gtk/gtkclist.c (real_select_row, real_unselect_row): 
	  fix selection bugs

Thu Mar  5 20:41:27 1998  Ian Main  <[e-mail]>

	* gtk/gtkfilesel.c: Added
	  gtk_file_selection_show_fileop_buttons(GtkFileSelection *fs), and
	  gtk_file_selection_hide_fileop_buttons(GtkFileSelection *fs).
	  Changed pulldown to only contain current directory name instead of
	  the full path.  Removed Help button (it can now be packed into the
	  button_area if desired).
		
	* gtk/gtkfilesel.h: Added GtkWidget *button_area (the fileop
	  buttons at the top are packed into this hbox), and GtkWidget
	  action_area (hbox below clists) to GtkFileSelection structure.

	* gtk/testgtk.c: Changed the filesel example to show off the hiding/
	  showing of fileop buttons, and the packing area.

1998-03-05  Federico Mena Quintero  <[e-mail]>

	* gdk/gdkprivate.h: Changed the name of default_filters to
	gdk_default_filters to avoid namespace pollution.  Yes, it just
	happened to me.

	* gdk/gdkglobals.c: 
	* gdk/gdkwindow.c (gdk_window_add_filter gdk_window_remove_filter): Likewise.

Thu Mar  5 12:32:06 1998  Marc Ewing  <[e-mail]>

	* gtk/gtkclist.c (select_row): emit UNselect on rows
	  that are not selected.

Thu Mar  5 01:22:06 1998  Owen Taylor  <[e-mail]>

	* gtk/gtkwidget.c (gtk_widget_unparent): Unset allocation
	  on unparent, to force reallocation if we get adding back
	  to a new parent which is already size-allocated.

	* gtk/gtktreeitem.[ch]: Keep track of separate +/- pixmaps
	  for each colormap, removed the idle hack.

	* gdk/gdk.c: Don't warn when unable to open XIM method,
	  since X11R5 apparently has no default method.

	* gtk/gtkwidget.c (gtk_widget_set_style_internal): Don't
	  call size_request on initial emission - since the
	  widget size isn't set yet, it can't change.

	* gtk/Makefile.am: New rules 'test' and 'test-debug' to run
	  testgtk with the correct working directory.

	* gtk/gtkentry.c (gtk_move_forward_word): 
	  Check for position at end of line.

Sun Mar  1 22:59:09 1998  Tim Janik  <[e-mail]>

	* gtk/gtkstatusbar.h: 
	* gtk/gtkstatusbar.c: complete api change to honour message contexts.
	unfortunaltely this also involved argument changes on the signal
 	emissions which will not be caught by the compiler. your callbacks
 	should look like:
  	void  message_text_popped (GtkStatusbar   *statusbar,
				   guint           context_id,
	                           const gchar    *text,
				   gpointer        func_data);

	* gtk/gtkwidget.c (gtk_widget_set_rc_style): eliminated bug about
	initial signal emission.
	(gtk_widget_set_parent): don't ensure style, just call
	gtk_widget_set_style_recurse.
	(gtk_widget_set_style_recurse): only change a widget's rc styles if
	if there has already been a lookup.
	
	* gtk/testgtk.c: adaptions for statusbar widget.
	substituted notebook pixmaps with pixmaps from fvwm, since
	we don't know where the originals came from.
	
	* gtk/gtkobject.c (gtk_object_data_destroy): call the destroy
	notifier with the objects data, not its internal structure.
	
	* gtk/gtkspinbutton.c (gtk_spin_button_button_press): small
	fix from lars.

	handlers.

Sun Mar  1 05:18:11 1998  Owen Taylor  <[e-mail]>

	* gtk/gtkentry.c gtk/gtktext.c gtkeditable.[ch]

	to make things look nicer. 
	
Sat Feb 28 23:58:54 1998  Owen Taylor  <[e-mail]>

	* gtk/gtkentry.[ch] gtktext.[ch] gtkeditable.[ch]

	Created a new base widget type Editable for the entry and
	text widgets, which encapsulates most of the selection and
	clipboard handling stuff, plus some common signals.

	Changed the Entry widget extensively to support this, 
	but the interface and appearance should be the same.

	Changed the Text widget moderately to support this.

	It now supports:

	- Selection style cut and paste
	- Clipboard style cut and paste
	- Emacs style key bindings (~same as Entry)
	- Word motion
	- "changed" signal

	There are definitely still some bugs in the new stuff.

	Use style->base for the background and style->text for
	the foreground.
	
	* gtkfilesel.c gtkspinbutton.c testgtk.c: small changes
	to fit the new interface more exactly.
	
Sat Feb 28 19:29:09 1998  Tim Janik  <[e-mail]>

	* gtk/gtkclist.c (gtk_clist_new_with_titles): retrive the clist widget
	from gtk_type_new (gtk_clist_get_type ()), not gtk_clist_new(),
 	otherwise gtk_clist_construct() gets called twice.

	* gtk/gtkhandlebox.h:
	* gtk/gtkhandlebox.c: emit signals when the child is attached/detached.

Sat Feb 28 15:18:36 1998  Tim Janik  <[e-mail]>

	* gtk/gtkpreview.c: fix behavior of gtk_preview_put() with
	srcx/srcy != 0, gtk-shige-980127-0.patch.gz by
	AOSASA Shigeru <[e-mail]>.

	* gdk: applied gtk-roebling-980121-0.patch.gz, patch for region
	support in Gdk, by Robert Roebling <[e-mail]>.

Fri Feb 27 15:31:55 1998  Tim Janik  <[e-mail]>

	* gtk/gtktipsquery.c: we make an active server grab now, this way we
	can change the cursor globally and don't need to tweak event masks
	of other windows.

	* gtk/gtkframe.c (gtk_frame_style_set): recompute label size.

	* gtk/gtkwidget.h:
	* gtk/gtkwidget.c:
	New signal GtkWidget::style_set to be emitted when a widget's style
 	changed. New flag GTK_RC_STYLE to indicate whether an rc lookup has
	been perfomed for the widget.
	(gtk_widget_ensure_style): New function.
	(gtk_widget_set_rc_style): New function.

	* docs/styles.txt: new file.

Fri Feb 27 01:11:55 1998  Owen Taylor  <[e-mail]>

	and refresh screen correctly if the text widget isn't frozen.
       
	- Fixed bug where text->first_line_start_index wasn't
	being updated correctly on insertion and deletion.
	
	- Added new public macro GTK_TEXT_INDEX (text, ind), and 
	function gtk_text_get_chars(text, index, nchars);
	
Thu Feb 26 22:36:46 1998  Owen Taylor  <[e-mail]>

	* gdk/gdkwindow.c gdktypes.c gdk.h:

Wed Feb 25 13:50:05 GMT 1998  Tony Gale <[e-mail]>

	* docs/gtkfaq.sgml: added questions on:
		- Why don't the contents of a button move when 
		  the button is pressed?
        	- How do I catch a double click event in 
 		  a list widget?         
     		- When compiling GTK+ I get an error like: 
		  make: file `Makefile' line 456: Syntax error 
          Removed questions on menus which are covered in the
	  tutorial.

	  Added link to HTML versions of FAQ and Tutori
