const ScreenWidth : longint = 800; procedure FormScaleScreen(AForm : TForm); var OldFormWidth : integer; begin with AForm do begin Scaled := true; if (SCreen.Width <> SCreenWidth) then begin OldFormWidth := Width; SCaleby(Screen.Width, ScreenWidth); Font.Name := '宋体'; Font.Size := (Width div OldFormWidth) * Font.Size - 1; end; end; end;
给个例子,与你的相反假设你在800*600的分辨率下设计的form,第一步: inplementation const ScreenWidth: LongInt = 800; {I designed my form in 800x600 mode.} ScreenHeight: LongInt = 600;{$R *.DFM}procedure TForm1.FormCreate(Sender: TObject); begin scaled := true; if (screen.width <> ScreenWidth) then begin height := longint(height) * longint(screen.height) div ScreenHeight; width := longint(width) * longint(screen.width) div ScreenWidth; scaleBy(screen.width, ScreenWidth); end; end;下一步,要让每个子控制的字体改变到合适的大小: type TFooClass = class(TControl); { needed to get at protected } { font property }var i: integer; begin for i := ControlCount - 1 downto 0 do TFooClass(Controls[i]).Font.Size := (NewFormWidth div OldFormWidth) * TFooClass(Controls[i]).Font.Size; end;
ScreenWidth : longint = 800;
procedure FormScaleScreen(AForm : TForm);
var
OldFormWidth : integer;
begin
with AForm do
begin
Scaled := true;
if (SCreen.Width <> SCreenWidth) then
begin
OldFormWidth := Width;
SCaleby(Screen.Width, ScreenWidth);
Font.Name := '宋体';
Font.Size := (Width div OldFormWidth) * Font.Size - 1;
end;
end;
end;
inplementation
const
ScreenWidth: LongInt = 800; {I designed my form in 800x600 mode.}
ScreenHeight: LongInt = 600;{$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;下一步,要让每个子控制的字体改变到合适的大小:
type
TFooClass = class(TControl); { needed to get at protected }
{ font property }var
i: integer;
begin
for i := ControlCount - 1 downto 0 do
TFooClass(Controls[i]).Font.Size :=
(NewFormWidth div OldFormWidth) *
TFooClass(Controls[i]).Font.Size;
end;
