A simple solution would be just to play around with the stringrid properties - like this
object Form1: TForm1
Left = 192
Top = 114
Width = 696
Height = 480
Caption = 'Form1'
Color = clBtnFace
Font.Charset = DEFAULT_CHARSET
Font.Color = clWindowText
Font.Height = -11
Font.Name = 'MS Sans Serif'
Font.Style = []
OldCreateOrder = False
PixelsPerInch = 96
TextHeight = 13
object StringGrid1: TStringGrid
Left = 192
Top = 64
Width = 201
Height = 81
BorderStyle = bsNone
Color = clBtnFace
ColCount = 3
FixedCols = 0
RowCount = 3
FixedRows = 0
Font.Charset = ANSI_CHARSET
Font.Color = clWindowText
Font.Height = -11
Font.Name = 'Bell MT'
Font.Style = [fsBold]
Options = [goFixedVertLine, goFixedHorzLine, goVertLine, goHorzLine, goRangeSelect, goEditing]
ParentFont = False
ScrollBars = ssNone
TabOrder = 0
OnSelectCell = StringGrid1SelectCell
end
end
& the code to avoid people editing the row/col headers:
procedure TForm1.StringGrid1SelectCe
ARow: Integer; var CanSelect: Boolean);
begin
If (Arow=0) or (ACol=0) then CanSelect:= false;
end;
David
aikimark > true lol
mikezang > the code works for me, I am guessing that we aren't prehaphs using the same properties for the stringgrid - download this example
www.davidbirch2.com/hidden
David
in your FormCreate do this
var
myRect: TGridRect;
begin
stringgrid1.cells[2, 2] := '3'; // add some data to the grid
{ optional
myRect.Left := 2; // set which cell is selected
myRect.Top := 2; // set which cell is selected
myRect.Right := 2; // set which cell is selected
myRect.Bottom := 2; // set which cell is selected
StringGrid1.Selection := myRect; // set which cell is selected
}
StringGrid1.Col:= 2; // set the selected cell as well
StringGrid1.row:= 2; // set the selected cell as well
StringGrid1.Options := StringGrid1.Options + [goEditing]; // allow editing
end;
and then in the SelectCell event do this :-
procedure TForm1.StringGrid1SelectCe
begin
if (StringGrid1.Cells[ACol,AR
begin
StringGrid1.Options := StringGrid1.Options + [goEditing]; //allow editing if cell has data
CanSelect := True; //allow selection if cell has data
end
else
begin
StringGrid1.Options := StringGrid1.Options - [goEditing]; //disallow editing if cell is empty
CanSelect := False; //do not allow selection if cell is empty
end
end;
Hi, TheRealLoki
I did the same as your code, but it doesn't work, I have a source, can you check it for me?
http://www.geocities.jp/mi
you do need the
grd.Options := grd.Options + [goEditing];
line, which you had commented out, to enable editing again if the user clicks in that area.
you might also like to add an "onEnter" event that fouses that cell and enables the editing (so you can tab into it and make changes instead of needing the mouse)
procedure TForm1.StringGrid1Enter(Se
begin
(sender as TStringGrid).col := 2;
(sender as TStringGrid).row := 2;
(sender as TStringGrid).Options := (sender as TStringGrid).Options + [goEditing]; //allow editing if cell has data
(sender as TStringGrid).EditorMode := True; // so the 1st character you type is written
end;
Try just this, it is a lot simpler, but I think it does everything you need
procedure TForm1.StringGrid1SelectCe
begin
CanSelect := ( (ACol = 2) and (ARow = 2) );
end;
and set your StringGrid.Options to have
goDrawFocusSelected, goEditing, goAlwaysShowEditor set to true
erm I was just looking at your source - on the first table on the onselectcell event you had
if (ACol = 1) and (ARow = 1) then
begin
// grd.Options := grd.Options + [goEditing];
CanSelect := false;
end
else
begin
grd.Options := grd.Options - [goEditing];
CanSelect := false;
end
if both options are false then you will never be able to select the cell !?
try changing it to
if (ACol = 1) and (ARow = 1) then
begin
grd.Options := grd.Options + [goEditing];
CanSelect := true;
end
else
begin
grd.Options := grd.Options - [goEditing];
CanSelect := false;
end
Which works for me
David
Hi, David
That source is old, I used that to try something, but I didn't get what I need, I have to click on that cell to get focus.
Or The focus will be set to cells[0, 0], even I set to cells[1,1] or col=1 and row=1.
You can try again and tell me the result. Can you use TAB to get focus on cells[1, 1]?
mikezang > I am on a machine which is delphi-less :( but can you check if the string grid has a ongetfocus event ? if so put something like this on it:
(sender as TStringGrid).col := 2;
(sender as TStringGrid).row := 2;
(sender as TStringGrid).Options := (sender as TStringGrid).Options + [goEditing]; //allow editing if cell has data
(sender as TStringGrid).EditorMode := True; // so the 1st character you type is written
David
Can you show me a simplest full sample? My screen looks like http://www.geocities.jp/mi
