Hi All,

I managed to successfully compile (Build) my Lazarus app without any error, warnings or hints. However, when I run it I get a runtime exception error:

Project Frog Retro Remake Game raised exception class 'Exception' with message:
No widgetset object. Plz check if the unit "interfaces" was added to the programs uses clause.

[OK] { button }

File "frog.lpr" ----------------------------------
program frog;
{$MODE Delphi}

uses
Forms,
MainUnit in 'MainUnit.pas' {MainForm},
uFixedWidthFonts in 'uFixedWidthFonts.pas',
FrameUnit in 'FrameUnit.pas' {TabFrame: TFrame},
PagesDlgUnit1 in 'PagesDlgUnit1.pas' {PagesDlg},
PlayAgainUnit in 'PlayAgainUnit.pas' {PlayAgainForm},

  IniFiles in 'IniFiles.pas', screen_strings;

{$R frog1.res}
begin
  Application.Initialize;
  Application.Title:='Frog Retro Remake Game';
  Application.CreateForm(TMainForm, MainForm);
  Application.Run;
end.
end of File "frog.lpr"--------------------------------

What part of the message do you not understand?

Hi Mattias & All,

Okay... I've been to bed and had some sleep... so now I'm thinking a little clearer. *SMILE*

When I first saw that message I thought that I needed to add "{$ Interfaces}" to my code. However, I now realize that I needed to add "Interfaces" to my "frog.lpr" uses clause.

I can now compile and run my unit... However, it still needs debugging.

For those interested, it is basically a TForm with a TPaintBox and I have a unit which reads a M$ Windowz bitmap (e.g. a .BMP file) of a bitmap font. The unit can paint the bitmap font to the TPaintBox with any colour text or background, and even in reverse video.

It's designed to mimic the fonts use on old Commodore PET computers (circa
1977) which had a mono green screen etc etc. Thats why its called "Frog Retro Remake Game" e.g. it's a "Retro" game.

I'll probably post a few more messages about how I'm going debugging it. *SMILE*
