Other / Re: Start using Blaise Pascal's teachings to persuade others to use FPC/Lazarus
« Last post by syntonica on Today at 07:35:04 am »
Maybe you could work his Wager into it. You're better off using Pascal. Just in case.  :D


Regarding Ruby,  Mac Homebrew is heavily dependant upon it. It's quite annoying...

Unix / Re: problems of using the fp IDE on Raspbian with putty
« Last post by Niklo on Today at 07:33:31 am »
Hello Marcov,
thank you very much. Now it works to write and build my test pascal program in the fp ide on my raspberry PI.
Here the lines I put into Options => Directories => Units:
/usr/lib/arm-linux-gnueabihf/fpc/3.0.4/units/arm-linux/
 /usr/lib/arm-linux-gnueabihf/fpc/3.0.4/units/arm-linux/*
 /usr/lib/arm-linux-gnueabihf/fpc/3.0.4/units/arm-linux/rtl
I add two screenshots:

Best regards,

General / Re: Pattern for defining class or record inside another class - to use as a list

Okay, answered my own question.  I need a local var to load and then add that to the list.

Code: Pascal  [Select]

Debugger / Re: How to make register window settings more persistent?
« Last post by ccrause on Today at 06:00:07 am »

I applied the patch. Big thanks

Other data suppliers have a separate CountValidState.  But that would not have helped, if it becomes invalid too.

And from review, I think at least gdbmi code would update the name list, if needed.

-------------------
I assume your tests where *nix?

I tested under Win, and noted (unrelated) that the TListView flickers like hell, if BeginUpdate is used.
I disabled that for Win....

Any such thing under *nix?

Yes, I tested this only in LInux where I didn't notice flickering. Perhaps the complex Count method was previously used to limit the update frequency of the listview?

Thanks, I'll take a look. If it's working or I get it working, I'll add it to the https://wiki.lazarus.freepascal.org/Portal:Mac

Hey Munair, wild guess, you have not selected the GTK3 widget set have you ?

It is a bit prone to those crashes at exit ....

General / Re: How to make a simple countdown timer?
« Last post by winni on Today at 02:11:56 am »
Hi!

The TDateTime format is a double.
The fractional  part is the part of the day, so 0.5 = 12 hours.

Change this: change the name of  'time' because time is a procedure in sysutils.
And change it to a double.
So:

Code: Pascal  [Select]
  1. var
  2. MyTime :  double = 1; // 24 hours
  3.  
  4. ....
  5.  
  6. procedure TForm2.CountdownTimer(Sender: TObject);
  7. begin
  8.   myTime := myTime - 1/(24*60*60);
  9.   Form1.Label1.Caption := TimeToStr(MyTime);
  10. end;  
  11.  
  12.  
  13.  

Happy Countdown!
