窗体在不同分辨率下的大小和控件位置、变形问题：在800*600下做了一个FORM，但到640*480下一看却变了形，控件的相对位置都变了，不知道如何解决，请教诸位高手。

implementation
const
ScreenWidth: LongInt = 800; {I designed my form in 800x600 mode.}
ScreenHeight: LongInt = 600;
{$R *.DFM}
procedure TForm1.FormCreate(Sender: TObject);
begin
scaled := true;
if (screen.width <> ScreenWidth) then
begin
height := longint(height) * longint(screen.height) DIV ScreenHeight;
width := longint(width) * longint(screen.width) DIV ScreenWidth;
scaleBy(screen.width, ScreenWidth);
end;
end;
下面是解决字体大小的代码:
USES typinfo; {Add this to your USES statement.}
var
i: integer;
begin
for i := componentCount - 1 downto 0 do
with components[i] do
begin
if GetPropInfo(ClassInfo, 'font') <> nil then
font.size := (NewFormWidth DIV OldFormWidth) * font.size;
end;
end;
下面的函数可以解决问题：
Form:需要调整的Form，OrgWidth：开发时屏幕的宽度，OrgHeight：开发时屏幕的高度。
注意：需要把Form的Scaled设置为True。
procedure AdjustForm(Form: TForm; const OrgWidth, OrgHeight: integer);
begin
with Form do
begin
Width := Width * Screen.Width div OrgWidth;
Height := Height * Screen.Height div OrgHeight;
ScaleBy(Screen.Width, OrgWidth);
end;
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
AdjustForm(Self,1280,1024);
end;
