[gtkada] Problems with upgrading Mine Detector game to GtkAda 2.2/Win98

[Jeffrey Carter]

I've been trying to upgrade the game to 2.2 on Win 98 with GNAT 3.15p, 
and have run into some problems I can't figure our how to work around. 
I've checked the list archives and comp.lang.ada without finding any 
solutions.

The first problem is the MS Sans Serif 8 problem others have reported:

** (mine_detector.exe:4294467463): WARNING **: Couldn't load font "MS 
Sans Serif 8" falling back to "Sans 8"

As Mine_Detector has 480 toggle buttons, many of which have their text 
changed in response to user actions, all the resulting output has a 
noticeable impact on performance. I have not been able to find a way to 
eliminate these messages. I've tried using Set_Use_Markup to use Sans 8, 
but have always had the markup appear in the labels' text.

The other problem is the use of a Gtk_Text inside a Gtk_Scrolled_Window 
to display the rules of the game. This worked OK with 1.13.2, although 
it displayed a black box at the end of wrapped lines. With 2.2, no 
visible text is displayed, although there are little arrows displayed at 
the ends of what should be wrapped lines (where the boxes appear with 
1.13.2), and one can scroll the window vertically. Displaying the rules 
dialog also generates some MS San Serif 8 warning messages.

Any assistance will be gratefully received.

I realize Win98 is not technically supported, but it's where the 1.13.2 
Windows version was created, so it seems that a 2.2 version should work 
there, too. I'm doing a Windows version first because GtkAda seems to 
have more problems under Windows than under Linux.

Thanks for any assistance.
