[SOLVED] TStringgrid at runtime *Thanks*

[guywest]

Good day,

Yesterday I spent almost a whole afternoon to get TStringgrid to do what I want (which works very easy and well in Delphi but not in Lazarus 2.0.2.

I want to create a grid on a form at runtime.

Several code examples found, nothing works.

Example:

Code: Pascal  [Select][+][-]

1. MyGrid := TStringGrid.Create(Self);
2.   MyGrid.Parent := Self;
3.   MyGrid.Visible := true;
4.   MyGrid.left := 20;
5.   MyGrid.top := 20;
6.   MyGrid.rowcount := 5;
7.   MyGrid.colcount := 5;
8.   MyGrid.width := 100;
9.   MyGrid.height := 100;
10.   MyGrid.Enabled := true;
11.   MyGrid.cells[1, 1] := 'hi';
12.  

NOTHING visible on the form. Changing parent to form name or create on form name in stead of Self does not change anything: always empty form.

Tried also with an empty grid at design time and then changing rows and columns (yes: with the columns.add, not by only changing colcount) at runtime but changes are not visible: the design time version is always displayed. No refresh, repaint, invalidate, ... helps.

Why does this not work?

As the stringgrid works very easily under Delphi but is a REAL pain in the ass in Lazarus (a lot of stupid error messages in other applications also), I really think the Stringgrid component of Lazarus really sucks. I'm a wrong?

Is there an important item that I don't know to make the Stringgrid of Lazarus work as easily as the Stringgrid of Delphi?

Thanks!

Self is the form you try to place it on?

This works for me....

Code: Pascal  [Select][+][-]

1. procedure TForm1.Button1Click(Sender: TObject);
2. Var
3.   G:TstringGrid;
4. begin
5.   G :=TStringGrid.Create(Self);
6.   G.Parent := Self;
7.   With G do
8.    Begin
9.      Bounds(0,0,200,300);
10.      Enabled := True;
11.      Cells[1,1] := 'Hi';
12.    end;
13. end;                          
14.  
15.

Are you sure that your code is really called? The code itself is correct and works if called for example from a button OnClick event handler.
In fact, the Lazarus StringGrid is much superior to that of Delphi, if offers many features for which the Delphi grid requires a third-party grid.

ME TOO ...

Hi!

Yes - works with no problem.

But RAW: nobody talked about ClLIME! Outsch!

Thanks to you all.

The code of Jamie works. VERY strange.

Is possible but with Delphi Grid I sometimes had an error, with the Lazarus Grid it RAINS errors.

I think Bart was on the correct path, where does "SELF" come from?
