[SOLVED] Unable to add empty lines in label control

[artem101]

Hello!

I discovered that it's impossible to add empty lines in Label control in Linux.

Code: Pascal  [Select][+][-]

1.   Label1.Caption:='one'+LineEnding
2.                  +'two'+LineEnding+LineEnding
3.                  +'three'+LineEnding+LineEnding+LineEnding
4.                  +'four';    

Code: Pascal  [Select][+][-]

1.   object Label1: TLabel
2.     Left = 0
3.     Height = 240
4.     Top = 0
5.     Width = 320
6.     Align = alClient
7.     AutoSize = False
8.     Font.Height = 13
9.     ParentColor = False
10.     ParentFont = False
11.   end

Tested in Linux Mint 21.1 XFCE and 20.3 MATE. Lazarus version is 2.2.4.

For comparision in Windows it works as expected.

Any ideas? Thanks.

In Manjaro Linux it works with qt5 widgetset, but I can confirm the issue when I switch to gtk2. As a workaround you could add a space:

Code: Pascal  [Select][+][-]

1. procedure TForm1.FormCreate(Sender: TObject);
2. begin
3.   Label1.Caption:='one'+LineEnding
4.                  +'two'+LineEnding+' ' +LineEnding
5.                  +'three'+LineEnding+' ' +LineEnding+' ' +LineEnding
6.                  +'four';
7. end;
