Hi,
Using fpc 2.1.5 on Mac Intel, I am getting a wierd error on this line:
Buffers[CurrentBuffer].DrawTo(MainForm.Canvas.Handle, 0,0);
With the following declarations:
public
{ Public declarations }
CurrentBuffer : Boolean;
Buffers: array [Boolean] of TBitmap32;
....
This exception:
TApplication.HandleException Invalid type cast
And this backtrace:
Breakpoint 1, 0x0000e0a6 in fpc_raiseexception ()
(gdb) bt
#0 0x0000e0a6 in fpc_raiseexception ()
#1 0x00056682 in SYSUTILS_RUNERRORTOEXCEPT$LONGINT$POINTER$POINTER ()
#2 0x00010fd7 in SYSTEM_HANDLEERRORADDRFRAME$LONGINT$POINTER$POINTER ()
#3 0x0000cf71 in fpc_class_as_intf ()
#4 0x00027ebf in TMAINFORM__TRANSFORMFRAME (SENDER=0xfb3020,
DONE=true, this=0xf2c810) at MainUnit.pas:359
#5 0x00022bf4 in TAPPLICATION__IDLE (WAIT=true, this=0xfb3020) at
application.inc:299
.....
What kind of typecast is that? I don't see any on the code. And why is
fpc_class_as_intf being executed? I don't see any interfaces being
used.
This code comes from a delphi example application, and I'm a little
lost about what is wrong or how to fix it.
Maybe the sintax array [Boolean] doesn't work and I should substitute
it by something like [0..1]
thanks,
