I have written a custom WDEF that implements a Motif-like window (3d-like,
shaded frames), with raised buttons for close and zoom boxes, drag bar and
grow corners and edges. The WDEF was written in C with MPW 3.0 on a Mac-II
running Multfinder.
I followed the guidelines in IM-I and IM-V:
.
.
.
- Use SysEnvirons to check for color quickdraw
- If in color:
. call GetCWMgrPort (...) to get the color port CWMgrPort
. synchronize CWMgrPort with the current port (WMgrPort)
. set port to CWMgrPort
- Allocate dataHandle and manually set adequate values into
(*theWindow->dataHandle)->windowState.stdState
- locked and unlocked all handles properly
.
.
.
To test I pasted the WDEF in a couple of applications (copies :-)): MacWrite,
MacDraw, sample applications from Apple's DTS, and PixelPaint. With the
exception of PixelPaint, which refused to display the window and its contents,
it worked w/o problems.
The real problem appeared when I pasted the WDEF into a copy of ResEdit 1.2b2.
The following things happen:
1. ResEdit's main window is displayed with a go away box. I checked the
window's goAwayFlag, and it is TRUE. Well, with the standard WDEF, no
go away box is displayed; why this strange behavior? If I hit the go away
box, the window closes, the desktop icons disappear, the disk spins a lot,
and then (ta-da) the window reappears. To make sure I was not seeing things
(and I tell you, working in my basement at 1:00AM makes you see lots of
things...) I even pasted WDEFs from SADE and MacProject II. The one from
Sade had no go away box; the one from MacProject (a floating palette) had
a go away box!
2. When editing a WIND resource that utilizes the new WDEF, ResEdit is unable
to display the scaled-down window image properly: the frame, buttons and
title are not displayed, only the contRgn is surrounded by the dotted
rectangle. This happens only if I set the port to CWMgrPort in the WDEF.
Not only that but when I reach for the menu bar, selections can be made,
but the pull-down menus don't get displayed. All these symptoms go away if
I don't use CWMgrPort (which means that in a Mac-II I cannot take full
advantage of color).
Since Apple-brand WDEFs, which are 'universal', don't exhibit these symptoms, either
I messed up (probably :-)) or have encountered some undocumented feature. I would
appreciate to receive some input on these problems.
Thanks,
