Thread: Mac OS X Experience

So I've resolved all the issues that I encountered in my previous
e-mails, and pgAdmin3 now compiles and links on Mac OS X.  I had to
change two calls to Show() to Show(true) and added the changes detailed
in my pgSequence.cpp patch.  Also, I changed some compile flags based
on Apple recommendations for porting programs to Mac OS X.  The changes
are in the latest autoconf code that Dave has (is going to?) put into
CVS.  Now, however, when I run the program, the following happens:

1) A while box the same size as the splash screen on linux and Windows
appears, but is empty.  This is obviously the splash page, but it's
empty.

2) The tip of the day box appears, filled in with a tip.

That's all the happens.  I *can not* click any of the buttons of the
checkbox in the tip of the day dialog.  There is no icon in the dock
bar.  There is no application menu.  I cannot select the window or exit
the program without using 'kill' from the command-line.

Any ideas?  Perhaps my changes did this, but I would doubt it.

Will be included in my next cvs commit.

Sounds like there's a problem with wxTipProvider.
You could try to comment out the accelerator code in frmMain.cpp in line
183ff., TipOfTheDay in pgAdmin3.cpp line 136 and winSplash=0 in line 69.
Then, all decorating windows are bypassed and the main window should
come up with usable menus. If not, I'm clueless.

I don't know why the splash screen doesn't display, but I do know what
the primary problem is with the app on Mac.  It is necessary to link
with the libwx_macd-2.4.rsrc file during compile.  I will try and
investigate how best to get pgadmin3 to automatically do this.

ahp

I created a small sample application and the splash screen displays
fine.

ahp

I lied in my last e-mail.  The splash screen only displays properly
without the code:

if (winSplash) {
     winSplash->Close();
     delete winSplash;
}

 From what I can tell, the bitmap is not displayed during the wxSleep(2)
call.  During this call the splash screen is white.  After the call the
windows gets destroyed before the bitmap can display.  If the above
code is commented out, the bitmap displays.  Without having looked at
the wxWindows docs yet, I would assume that the winSplash->Refresh()
should have taken care of displaying the bitmap, but this doesn't seem
to work on the Mac.  I will keep investigating.

ahp

Changing the frmSplash->Refresh() to frmSplash->Update() solves the
splash screen problem.  It looks like Refresh() doesn't do what it says
it does on Mac.  I will check and make sure that Update() works on the
other platforms.

ahp

Okay, running Rez against the app, and linking in Carbon.r and
libwx_macd-2.4.r, so now:

1) The splash screen shows correctly.
2) The tooltip box displays, and now I can close it.
3) The app still appears as a, say... 10px high by 1px window in the
upper-left corner.  I get a menu and an icon now, but I choose "Add
Server..." I get this error:

*** malloc[22891]: Deallocation of a pointer not malloced: 0xbffff520;
This could be a double free(), or free() called with the middle of an
allocated block; Try setting environment variable MallocHelp to see
tools to help debug
Segmentation fault

ahp

Okay, it looks like frmSplash->Update() is the better call than
Refresh().  I have tested this successfully on Mac and Linux.  Unless
anyone has any objections, this change should be made.

Two thoughts; can you resize the window, and can you tell (from logs or
a backtrace) where the crash occurs?

If you send a patch (does frmAbout need it as well?) I can test it on
Windows and apply as appropriate.

Thanks, Dave.
