How are the titles of the fixed columns of a string grid set?

[taazz]

Code: [Select]

  StringGrid1.Cells[0,0] := '0,0';
  StringGrid1.Cells[1,0] := '1,0';
  StringGrid1.Cells[2,0] := '2,0';
  StringGrid1.Cells[3,0] := '3,0';
  StringGrid1.Cells[4,0] := '4,0';
  //StringGrid1.Cells[5,0] := '5,0';

  //StringGrid1.Cells[0,0] := '0,0';
  StringGrid1.Cells[0,1] := '0,1';
  StringGrid1.Cells[0,2] := '0,2';
  StringGrid1.Cells[0,3] := '0,3';

Or alternatively (if your grid is designed with columns) you can use:

Code: [Select]

StringGrid1.Columns[0].Title.Caption := 'MyTitle';and of course you can do it in Object Inspector.

Does this mean that the cells of the fixed columns can only be set at runtime?
The Column editor doesn't appear capable of setting the titles of fixed columns.

Code: [Select]

  StringGrid1.Cells[0,0] := '0,0';
  StringGrid1.Cells[1,0] := '1,0';
  StringGrid1.Cells[2,0] := '2,0';
  StringGrid1.Cells[3,0] := '3,0';
  StringGrid1.Cells[4,0] := '4,0';
  //StringGrid1.Cells[5,0] := '5,0';

  //StringGrid1.Cells[0,0] := '0,0';
  StringGrid1.Cells[0,1] := '0,1';
  StringGrid1.Cells[0,2] := '0,2';
  StringGrid1.Cells[0,3] := '0,3';

As far as I can see there is no way to set any data at design time on a StringGrid so yes it is only at runtime.

[Blaazen]

It's possible, you can double click string grid on the form designer at design time.

Maybe I should mention some specific attitude toward the first row when FixedRow= 1;

Code: [Select]

  StringGrid1.Cells[0,0] := '0,0';
..


Or alternatively (if your grid is designed with columns) you can use:

Code: [Select]

StringGrid1.Columns[0].Title.Caption := 'MyTitle';

I am trying it, but none of the solutions offered does not work if FixedCols= 1 and FixedRows=1.

For example in the following code first two lines work, but the third line does not.

Code: [Select]


StringGrid1.Cells[0,0] := '0,0';
StringGrid1.Cells[0,1] := '0,1';
StringGrid1.Cells[1,0] := '1,0';

Respectively, 

Code: [Select]

StringGrid1.Columns[0].Title.Caption := 'MyTitle';

Will not change the title caption of the leftmost column, but of the next one.


Here is another case, when  FixedCols= 2 and FixedRows=2.

Code: [Select]

StringGrid1.Cells[0,0] := '0;0';
 StringGrid1.Cells[0,1] := '0;1';
 StringGrid1.Cells[0,2] := '0;2';
 StringGrid1.Cells[1,0] := '1;0';
 StringGrid1.Cells[1,1] := '1;1';
 StringGrid1.Cells[1,2] := '1;2';
 StringGrid1.Cells[2,0] := '2;0'; //Line not working
 StringGrid1.Cells[2,1] := '2;1';
 StringGrid1.Cells[2,2] := '2;2';
 StringGrid1.Cells[3,0] := '3;0'; //Line not working

Te recapitulate:
1. StringGrid1.Cells[y,0]  does not work in Row 0, when FixedRows is>0;
2.  StringGrid1.Columns[y].Title.Caption := 'MyTitle'; will not work when y is < FixedCols.

[Blaazen]

Te recapitulate:
1. StringGrid1.Cells[y,0]  does not work in Row 0, when FixedRows is>0;
2.  StringGrid1.Columns[y].Title.Caption := 'MyTitle'; will not work when y is < FixedCols.

ad 2) It is expected behavior. Grid has fixed columns + columns designed by Columns property.

ad 1) Cells[] should work always, regardless how the grid was designed. BTW, coordinates are Cells[x, y] i.e. horizontal, vertical.

This:

Code: [Select]

StringGrid1.Cells[0,0] := '0,0';
StringGrid1.Cells[0,1] := '0,1';
StringGrid1.Cells[1,0] := '1,0';works perfectly here.

[CM630]

Here is where its hiding:
The following code works:

Code: [Select]

procedure TForm1.Button1Click(Sender: TObject);
var
  MyStringGrid: TStringGrid;
begin
   MyStringGrid:=TStringGrid.Create(Form1);
   MyStringGrid.Parent:=Form1;
   MyStringGrid.Left:=8;
   MyStringGrid.RowCount:=3;
   MyStringGrid.ColCount:=3;
//   MyStringGrid.Columns.Add;
//   MyStringGrid.Columns.Add;
   MyStringGrid.FixedCols:=1;
   MyStringGrid.FixedRows:=1;
   MyStringGrid.Cells[0,0] := '0,0';
   MyStringGrid.Cells[0,1] := '0,1';
   MyStringGrid.Cells[1,0] := '1,0';
end;And this code does not work:

Code: [Select]

procedure TForm1.Button1Click(Sender: TObject);
var
  MyStringGrid: TStringGrid;
begin
   MyStringGrid:=TStringGrid.Create(Form1);
   MyStringGrid.Parent:=Form1;
   MyStringGrid.Left:=8;
   MyStringGrid.RowCount:=3;
//   MyStringGrid.ColCount:=3;
   MyStringGrid.Columns.Add;
   MyStringGrid.Columns.Add;
   MyStringGrid.FixedCols:=1;
   MyStringGrid.FixedRows:=1;
   MyStringGrid.Cells[0,0] := '0,0';
   MyStringGrid.Cells[0,1] := '0,1';
   MyStringGrid.Cells[1,0] := '1,0';
end;I have no idea if that's how it should work or it's a bug.

[Blaazen]

I see now. Changing Title of columns designed by Columns property is restricted of some reason. You can try to report it (if nobody else did yet).

[CM630]

Please let me know on which version of the both in your signature have you tried it, so I can add this info in the bugzilla.

[Blaazen]

In SVN 1.3 on Linux-Qt and 1.2 in Wine. IMO this restriction is useless.

[CM630]

Reported as bug 26269.

[CM630]

So, the bug is fixed- it is now documented, and it became a feature.
