Can someone tell me how to specify a DLOG or ALRT button to be a highlighted default button (I have ResEdit v1.d4). According to Mac Revealed 2 this is done automatically to if the button is first in the item list, this is true except that it doesn't get highlighted. What's the latest word about version 3 of LightspeedC? I haven't seen anything on the net recently about it. Is it out yet? How do I get an upgrade? Thanks in advance.

The first item in the DITL will be highlighted when an ALRT is drawn using the system call for alerts. There's no special treatment for the first DITL item under a DLOG. The highlighting is not there when the ALRT is drawn in ResEdit, because it's not really an alert - it's just a drawing of the DITL items.

Hilighting the default button in an alert box is automatically done
for you if the button is the first item in the DITL list.
To hilight a default button in a Dialog box, you will have to do the
hilighting yourself. The simplest way is to use GetDItem (...) to
get the Rect that the button is positioned at; InSet that rect about
negative 5 (-5) pixels (that actually makes it larger); set the pen
width to 3 pixels and draw a roundRect. This will draw the heavy border
around the button. Reset the pen width and the box, and you're done.
A few points: make the DLOG invisible in the resource and put the
hilighting routine immediately after the call to retrieve the DLOG.
Then use ShowWindow to draw the dialog before calling ModalDialog.
Otherwise, the drawing of the hilighting will be out of sync with
the appearing of the window.
Also: unless this is for your own use only, please make the default
button be the least disasterous option to data already saved unless
the dialog is confirmation for updating saved data.
I'm sorry I don't have actual code segments here at work. If you
have problems and need help, email to me at the address below.

According to IM V1 (P. 407), here is the way to highlight the default button so thast it looks like the normal highlit default button: PenSize(3,3); InsetRect(displayRect,-4,-4); FrameRoundRect(displayRect,16,16); where displayRect is the rect of the button. According to AUG, if you don't do this, then you shouldn't support the return and enter key as default substitutes in your DLOG. -- ..........................................................................

I have a feeling I read somewhere a year ago that you have to do more than this; if an alert comes up in front of the dialog (or if it is a modeless dialog?) your new rectangle will not be properly updated with just the code shown above. I couldn't find a tech note on the subject, but someone from Apple described somewhere how to do this right, maybe with a userItem. /JBL UUCP: {backbone}!bbn!levin USPS: BBN Communications Corporation ARPA: levin@bbn.com 50 Moulton Street POTS: (617) 873-3463 Cambridge, MA 02238

One thing IUve noticed about hilighting default buttons is that most
dialog default buttons lose their hilighting when the dialog is updated.
You can see this in most applications when the screen is updated after
restoring from a screen saver or when switching back to the application
under MultiFinder or Switcher. To "fix" this you need to create a fake
userItem and call SetDItem to set the procedure below as the MyItem
procedure for this fake userItem. I'm still a novice Mac Programmer,
so if anyone sees any problems with this routine, please let me know.
The following is used in my LSP programs:
{----------------------------------------------------------------- }
{ Put a frame around the specified Dialog button - usually 1 }
{ This procedure has two parameters. The second parameter is }
{ essentially a dummy parameter so that this routine may be }
{ specified as a MyItem routine }
{----------------------------------------------------------------- }
PROCEDURE DLOGFrameDefault(DLOGptr:dialogPtr,itemNo:integer);
VAR
curPen : PenState;
theItemType : integer;
theItemHandle : Handle;
theRect : rect;
DLOGdata : DialogPeek;
BEGIN
DLOGdata := DialogPeek(DLOGptr);
GetDItem(DLOGptr, DLOGdata^.aDefItem, theItemType, theItemHandle, theRect);
IF theItemType = (ctrlItem + btnCtrl) THEN
BEGIN
GetPenState(curPen);
PenSize(3, 3);
InsetRect(theRect, -4, -4);
FrameRoundRect(theRect, 16, 16);
SetPenState(curPen)
END
END;

I handle the issue of highlighting default button by implementing my
own library of standard dialog-filters that I use for all of my dialogs.
In the standard dialog filtering, part of the update code highlights
d^.aDefItem if it's a button. The code also mimics the ROM routines in
that a press of the Return or Enter key dismisses the dialog and returns
d^.aDefItem if the default button is enabled. This way, I can
have standard bold default button and Return-key highlighting of
things like Standard File boxes (by using SFP{Get, Put}File), as
well as my own custom dialog boxes....

if you are doing your own filter proc, remember:
1.) <return> and <enter> should be synonyms for OK
2.) <Clear> <Escape> and <Cmd>-. should be synonyms for Cancel.
3.) <Cmd>-? should get you help
4.) <Cmd>-x, <Cmd>-X, <cmd>-c, <cmd>-C, <Cmd>-v, and <Cmd>-V should
do cut, copy, and paste repsectively,
5.) <Cmd>-z should do undo.
I wish Apple would get on the ball and augment their own standard filter
proc to meet their own user interface guidlines.
