This has nothing to do with ARM processors. Show us some code - compilable code -... Then you will get more reasonable answers.

Just only, New Project- add an showmessage inside of OnShow Event and run the program in a raspberry pi 4. Sometimes the code inside onshow dont do nothing.

Code: Pascal  [Select][+][-]
  1. unit unit2;
  2.  
  3. {$mode objfpc}{$H+}
  4.  
  5. interface
  6.  
  7. uses
  8.   Classes, SysUtils, Forms, Controls, Graphics, Dialogs;
  9.  
  10. type
  11.  
  12.   { TForm1 }
  13.  
  14.   TForm1 = class(TForm)
  15.     procedure FormShow(Sender: TObject);
  16.   private
  17.  
  18.   public
  19.  
  20.   end;
  21.  
  22. var
  23.   Form1: TForm1;
  24.  
  25. implementation
  26.  
  27. {$R *.lfm}
  28.  
  29. { TForm1 }
  30.  
  31. procedure TForm1.FormShow(Sender: TObject);
  32. begin
  33.    ShowMessage('OnShow Work!');
  34.  
  35.    close;
  36. end;
  37.  
  38. end.  
  39.

Remove the close, because ShowMessage is not modal. That goes for every platform btw.
I actually get compliments for being rude... (well, Dutch, but that is the same)

I probalbly misunderstand you here, but ShowMessage shows a modal dialog on all platforms AFAIK.

On Linux it is not modal, as you can see from the emalgamation of popups while using -glh.
That should not happen if ShowMessage was modal.

ShowMessage is supposed to be modal, because it's only supposed to return once the dialog window is closed. This means that (per thread) there can only be one such window open.

Which isn't the case on Linux/gtk2..
I know all that.

A modal Window should halt execution before any other code gets executed in the same thread.

Which makes both of us wrong.
You: stating that ShowMessage is, on every platform, not modal.
Me: stating it is modal.
But you seem to be worng on more platforms than I. So, I win  O:-)

Hello.
Where can I place a proposal for the FPDoc documentation module?
Suggestion: after renaming the variable (by F2), as well rename the variables in the xml file.

Thank you for your great effort !
Using Lazarus and seeing its development day by day is such a joy.
