Hello,

I'm completely new to Delphi and Lazarus (I only studied Turbo
Pascal), so I ask for help here.

I cannot understand how to make button caption multiline; Google
haven't helped and manuals too. Can anyone please tell me what should
I do or where can I find examples?

Use a TSpeedButton with an image.

You can do also:

Code: [Select]SpeedButton1.Caption := 'a' +#13#10 + 'b';

Thanks, I'll try it.
As for code you wrote, where should I insert it? Into some procedure
related to form creation?

Yes.

Ok, that's all for the moment. Going to try your advice tomorrow.

don't use #13#10, use the constant LineEnding instead

Thanks for the advice, but I can see no essential difference  . Am I
mistaken?

Windows / Linux difference . No CR on Linux.

This works in windows.  I have not tried it with *nix.

Code: [Select]  SpeedButton1.Caption := 'Row1' + sLineBreak + 'Row2';

Code: [Select]SpeedButton1.Caption := 'Row1' + sLineBreak + 'Row2';
SpeedButton2.Caption := 'Row1' + LineEnding + 'Row2';
SpeedButton3.Caption := 'Row1' + #13#10 + 'Row2';

none of them works for me

I tried again on TButton and TBitBtn
all 3 codes working good!

so, maybe you should not use SpeedButton if you don't have image on
it.

LineEnding is mapped to #13#10 in Windows, #10 in Linux and #13 in
Mac. If you want your code to be cross platform, do not use hard-coded
values, but always use cross-platform constants instead.

Code: [Select]....  .Caption := 'Row1' + LineEnding + 'Row2';For me
works for all three, TButton, TBitBtn and TSpeedButton (Linux+Qt).

Thank you all for the explanation guys  . Though I'm writing a Windows
program, I'm going to follow your advice.
