I'm having trouble porting a working gui/modal program from
Linux to Windows. It runs fine on Linux, and runs for a while
on Windows, but ends up with the following error:
gui__center_string(&null,105,57,"N40",&null) from line 43 in textbutton.icn
TextWidth(&null,"N40") from line 205 in guiprocs.icn
It seems to occur in the following loop:
while *(q := select(udp_port,2)) > 0 do
every f := !q do
{
r := receive(f)
...
button[index].attrib( "bg=" || color, "fg=black" )
button[index].set_attribs( "bg=" || color, "fg=black" )
button[index].finally()
button[index].init()
button[index].resize()
}
When several udp msgs are received together, requiring several
buttons to change color, after the loop exits (and processing
goes back to the modal event loop?), the error occurs. When one
message is received (alone), and only one button changes color,
it seems to work fine.
(I'm not sure about the finally, init, or resize, but calling
them makes the button color take effect.)
Full error text is at http://www.halcyon.com/wturner/windows_error_msg.txt
Any suggestions?
