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 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。
