Hi All,

why doesn't the control (TButton) fit the cell in a StringGrid when I
do this

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TForm1.StringGrid1DrawCell(Sender: TObject; aCol, aRow: Integer;
aRect: TRect;  aState: TGridDrawState);begin  if (aCol = 1) and (aRow
= 2) then    Button2.SetBounds(aRect.Left, aRect.Top, aRect.Width,
aRect.Height);   (Sender as TStringGrid).DefaultDrawCell(aCol, aRow,
aRect, aState);end;  Its close but about 10 pixels off

It should be something like this:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TForm1.StringGrid1DrawCell(Sender: TObject; aCol, aRow: Integer; 
aRect: TRect; aState: TGridDrawState);var  TheGrid: TStringGrid;begin 
if not(Sender is TStringGrid) then Exit;  TheGrid := (Sender as
TStringGrid);  if (aCol = 1) and (aRow = 2) then   
Button1.SetBounds(aRect.Left + TheGrid.Left, aRect.Top + TheGrid.Top, 
    aRect.Width, aRect.Height);end;

hard to say...

could be borderspacing values set in the control?

the control may have the wrong parent..?

The control could be scrolled alittle ?

Not hard. 

It's about the coordinate origin. The button's coordinate origin is
the form's top left corner but the aRect in the event is using the
grid's top left corner as its origin.
