我已经在字符串网格中添加了图标,但是我遇到了一个问题,并非所有图形都已对齐。我试图重新设计文本的中心,使图标对齐,但没有运气。我试图研究位图及其功能,但我没有(所以我认为)发现任何可以帮助我的东西。有人可以帮帮我吗?
编辑(从错误回答问题中添加的代码):
bitmap := Tbitmap.Create;
bitmap.LoadFromFile('equal.bmp');
bitmap.SetSize(150,60);
stringgrid1.Canvas.StretchDraw(stringgrid1.CellRect(3,J), bitmap);
SetTextAlign(StringGrid1.Canvas.Handle, TA_CENTER);
StringGrid1.Canvas.TextRect(stringgrid1.CellRect(3,J),
(stringgrid1.CellRect(3,J).Left+stringgrid1.CellRect(3,J).Right) div 2,
stringgrid1.CellRect(3,J).Top + 5,StringGrid1.Cells[3,J]);
SetTextAlign(StringGrid1.Canvas.Handle, TA_LEFT);
答案 0 :(得分:4)
这是一个例子(Delphi 7,因为它是我方便的,但代码应该在D2010中工作):
procedure TForm1.StringGrid1DrawCell(Sender: TObject; ACol, ARow: Integer;
Rect: TRect; State: TGridDrawState);
var
Bmp: TBitmap;
CellText: string;
R: TRect;
const
L_PAD = 5; // Amount between right side of image and start of text
T_PAD = 5; // Amount between top of cell and top of text
begin
// Some text to display in cells.
CellText := Format('Row: %d Col: %d', [ARow, ACol]);
// Draw an image along the left side of each cell in the first
// col (not the fixed ones, which we'll leave alone)
if ((ACol = 1) or (ACol = 3)) and (ARow > 0) then
begin
Bmp := TBitmap.Create;
try
Bmp.LoadFromFile('C:\glyfx\common\bmp\24x24\favorites24.bmp');
if ACol = 1 then // left align image
begin
R.Top := Rect.Top + 1;
R.Left := Rect.Left + 1;
R.Right := R.Left + Bmp.Width;
R.Bottom := R.Top + Bmp.Height;
StringGrid1.Canvas.StretchDraw(R, Bmp);
StringGrid1.Canvas.TextOut(R.Right + L_PAD, R.Top + T_PAD, CellText);
end
else
begin // right align image
StringGrid1.Canvas.TextOut(Rect.Left + L_PAD,
Rect.Top + L_PAD,
CellText);
R.Top := Rect.Top + 1;
R.Left := Rect.Right - Bmp.Width - 1;
R.Right := Rect.Right - 1;
R.Bottom := R.Top + L_PAD + Bmp.Height;
StringGrid1.Canvas.StretchDraw(R, Bmp);
end;
finally
Bmp.Free;
end;
end
else
StringGrid1.Canvas.TextOut(Rect.Left + L_PAD, Rect.Top + T_PAD, CellText);
end;
这是它的样子:
