1999-03-04  James Ingham  <jingham@cygnus.com>

	* modal.tcl (ModalDialog): Handle WM_DELETE_WINDOW by calling the
	cancel method.  Also set unpost_notification to different values
	in unpost & the destructor, so if the object dies irregularly, you 
	know not to try to double destruct it.

1999-03-03  James Ingham  <jingham@cygnus.com>

	* warning.tcl (WarningDlg::constructor):Destroy with unpost.

	* util.tcl (get_disassembly_flavor, set_disassembly_flavor,

 	disassembly flavors.
	(list_element_strcmp): New function for lsort -command on lists.

	* tracedlg.tcl (TraceDlg): Change combobox callback to reflect new 
	after behavior.

	* targetselction.itb (TargetSelection::save): If the target
	is not valid, tell the user rather than simple refusing to go
	away.
 	Also move stuff around to isolate the instance dependant stuff as
	much as possible
	Also replace delete with unpost.

	* targetselection.ith (TargetSelection): Make as much of the
	initialization stuff Class functions as possible.  Then only
	initialize it once.

	* srcwin.ith (_update_title): initialize need_files.

	* srcwin.itb (SrcWin::_build_win): I changed the combobox so it
	ran its code in an idle handler, so we can take out all the after
	idle... cruft here.

	* srctextwin.ith (SrcTextWin): Added textheight variable so you
	can adjust the height of the text display.

	* srctextwin.itb (SrcTextWin::build_win): Don't hardcode the size
	of the text window, set it with the textheight option instead.  
	Also replace childsite with "component text" wherever required.

	* srcpref.itb (SrcPref::build_win, set_flavor): Added the Intel
 	disassembly flavor combobox.  Added set_flavor method to support
	this.
	* srcpref.ith: Added declaration for set_flavor, and
	disassembly_flavor instance variable.

	* modal.tcl (ModalDialog::post, unpost): Added unpost method to
	provide a more regular way to dismiss the dialogs.  Just
	destroying them was leading to funny destruction order bugs.
	Added cancel method, which is what client code should call to
	"force close" the dialog, so child classes can override, and do
	some cleanup.

	* memwin.itb (MemWin::destructor): Call the cancel method of the
	Preferences dialog (if it is posted) rather than just destroying
	it.

	* mempref.itb (MemPref::ok): call unpost, since this is a modal
	dialog.

	* managedwin.itb (ManagedWin::reveal): Used to be called raise.
	Don't reuse Tcl or Tk commands unless there is a really good
	reason to...
	(ManagedWin::destroy_toplevel): renamed from delete, which
	conflicts both with the Itcl1.5 delete method, and the Itcl3.0
	delete command...  Also, don't use this as the way to destroy
	ManagedWins, rather destroy the object and let the object take
	care of removing its toplevel.
	(ManagedWin::_create): Group all the windows with 
	. for WindowManagers that properly handle this.
	(ManagedWin::_create): Use dont_remember_size
	rather than the instance variable.  Also, windows which don't
	remember size are not necessarily transient.
	(ManagedWin::_create): Only call post if the
	ManagedWin also isa ModalDialog.  It is clearer what is going on.
	* managedwin.ith: Carry through the name changes.
	
	* main.tcl: call init_disassembly_flavor for Intel assembly
	flavors.

	*main.tcl: Group . with .  This is half of the work required to
	play nice with WindowMaker.  The other half waits till we can get
	gdb to pass the command-line arguments to Tcl.

	* interface.tcl: Add file_changed_hook to the hooks.  The browser
	window watches this and refreshes the file box if it changes.

	* globalpref.ith (GlobalPref): This should be a modal dialog.
	* globalpref.itb (GlobalPref::build_win): call update idletasks,
	not update.  Since we are calling update, there is no reason to
	delay calling resize_font_item_height.
	* globalpref.itb: Replace destroy toplevel with unpost.

	* debugwin.itb (DebugWin::build_win): Replace childsite with
	"component text"

	* console.itb (Console::_build_win): Replace childsite with
	"component text"

	* browserwin.itb: Rewritten pretty completely.
	* prefs.tcl (pref_set_defaults): add the browser preferences.

	* prefs.tcl (pref_set_defaults): add the intel disassembly flavor
	preference.

	* about.tcl (About): This should be a modal dialog.

1999-03-02  James Ingham  <jingham@cygnus.com>

	* globalpref.itb (GlobalPref::make_font_item): Don't do the
 	resize_font_item_height here, since an update can cause the resize
 	before all the windows are built.  Delay to the end of build_win
 	instead.

1999-02-24  James Ingham  <jingham@cygnus.com>

	* toolbar.tcl (remove_button): Specify the row in the toolbar from 
	which you are removing the item.  On Windows, there are two rows
	in the standard toolbar...

1999-02-22  Martin Hunt  <hunt@cygnus.com>

	* warning.tcl (WarningDlg::constructor): Remove extra quote
	that was causing loading of this module to fail.

	* managedwin.itb (ManagedWin::_create): If the pack fails
	(for example because the warning dialog reliazed it should
	ignore the warning) print a warning debug message and return.
	Also, while testing, tell the window manager to position
	the window without asking the user for the position.

1999-02-18  Martin Hunt  <hunt@cygnus.com>

	* srctextwin.itb (SrcTextWin::FillAssembly): As a last resort, 
	if the disassembly fails for some reason, switch to the scratch
	pane and write in a message about not being able to disassemble.

1999-02-18  Martin Hunt  <hunt@cygnus.com>
	
	* helpviewer.ith (HtmlViewer): Add thread and function
	browser windows to help index.

	allow use of an internet browser to read help files.
	
	* prefs.tcl (pref_set_defaults): Add preference gdb/help/browser.
	Default is to use builtin html help.

	* helpviewer.itb (HtmlViewer::open_help): New public proc.
	Depending on preferences, opens help in external browser or
	internal htmlviewer.

	* toolbar.tcl (create_help_menu): Use HtmlViewer::open_help.

1999-02-17  Martin Hunt  <hunt@cygnus.com>
	
	* managedwin.itb (ManagedWin::_create): Restore some lines that

1999-02-12  Martin Hunt  <hunt@cygnus.com>

	public variable "nosize" the size will not be set, only the position.
	* browserwin.ith (toggle_all_bp): Add public variable "nosize".	

1999-02-12  Martin Hunt  <hunt@cygnus.com>

	* srcbar.tcl (create_menu_items): Ditto.
	* memwin.itb (MemWin::create_prefs): Ditto.

	and post now that all windows use new manager.

	* warning.tcl (WarningDlg): Rewrite of entire class to use
	new itcl 3.0 class. Also now uses a "class name" to keep
