Where did my form Controls go?
lazarus / 10-Designer

Hi,
I'm a new user and somehow none of my controls are visible when
compiled.Editing the form is no prob, all components are there but
they disappear at run time. Other programs have no problems loading
them (example programs). I must have messed up a global setting
somewhere because any new program I make has the same issue as my app.

What am I missing?

Thanks in advance.

Here is the standard header when creating a new project, if that
helps...

program project1;

{$mode objfpc}{$H+}

uses
  {$IFDEF UNIX}{$IFDEF UseCThreads}
  cthreads,
  {$ENDIF}{$ENDIF}
  Interfaces, // this includes the LCL widgetset
  Forms, Unit1, LResources
  { you can add units after this };

{$IFDEF WINDOWS}{$R project1.rc}{$ENDIF}

begin
  {$I project1.lrs}
  Application.Initialize;
  Application.CreateForm(TForm1, Form1);
  Application.Run;
end.

Hi,
To compare your code with mine, I create a new project with a single
unit, and some controls on it. Using Lazarus 0.9.29, project code is
Code: [Select]program Project1;

{$mode objfpc}{$H+}

uses
  {$IFDEF UNIX}{$IFDEF UseCThreads}
  cthreads,
  {$ENDIF}{$ENDIF}
  Interfaces, // this includes the LCL widgetset
  Forms, Unit1
  { you can add units after this };

{$R *.res}

begin
  Application.Initialize;
  Application.CreateForm(TForm1, Form1);
  Application.Run;
end.
and everything shows fine.
There are some differences with yours. I am working on Windows 7. What
is your platform?

Quoteall components are there but they disappear at run timeensure you
have (Laz 0.9.28.2 and below with FPC 2.2.4 and below):
Code: [Select]initialization
  {$I yourformunit.lrs}or (Laz 0.9.29 and FPC 2.4.0 and above):
Code: [Select]{$R *.lfm}in the unit containing your form.

Hi,
Thanks for your quick response, fellows.

My issue, whatever I tweaked wrong, is only a problem with the file
apparently (so far). I am now able to compile forms with components. I
un-installed and reinstalled version 9.28.4 beta last night but still
had issue. I reboot this morning and, voila...my controls work for a
new project. Duh...

I am transferring the code I need to a new proj and all is fine.

Ps. Am I using the best version for XP?

no. note the link Daily Snapshots at the top left of this page. take
the 8th file (Lazarus + fpc 2.4.3 / win32 /
Lazarus-0.9.29-28515-fpc-2.4.3-20101128-win32.exe)

aren't meant for those writing programs with stable Lazarus version.
Though IMO it's almost as stable as the stable version :p

Hmm... is it really a good idea to use dailies of a development
version? Especially for production use... Though for experimenting it
might be fine.

QuoteHmm... is it really a good idea to use dailies of a development

currently suffering from a big bug (like wrong register allocation in
fpc and the change of autosizing / layouting algorithm in lcl), then I
suggest to wait until it's solved.

QuoteHmm... is it really a good idea to use dailies of a development

go for it. yes,

now and then bugs show up (or are more likely reintroduced) but it's
usually no big deal. if it worries you, just take today's version and
don't upgrade it until your project is done.

I guess it might be feasible to do just that - install a snapshot,
test it and if it works fine, keep it... If not, try another one...

Perhaps it would be good to test some snapshots and use them as weekly
or monthly public releases... I once had a similar idea, maybe I could
revisit that...
