- 代码如下:
- unit untFixForm;
- interface
- uses
- Classes, SysUtils, Controls, Forms;
- type
- TFontedControl = class(TControl)
- public
- property Font;
- end;
- TFontMapping = record
- SWidth : Integer;
- SHeight: Integer;
- FName: string;
- FSize: Integer;
- end;
- procedure FixForm(AForm: TForm);
- procedure SetFontMapping;
- var
- FontMapping : array of TFontMapping;
- implementation
- procedure SetFontMapping;
- begin
- SetLength(FontMapping, 3);
- // 800 x 600
- FontMapping[0].SWidth := 800;
- FontMapping[0].SHeight := 600;
- FontMapping[0].FName := '宋体';
- FontMapping[0].FSize := 7;
- // 1024 x 768
- FontMapping[1].SWidth := 1024;
- FontMapping[1].SHeight := 768;
- FontMapping[1].FName := '宋体';
- FontMapping[1].FSize := 9;
- // 1280 x 1024
- FontMapping[2].SWidth := 1280;
- FontMapping[2].SHeight := 1024;
- FontMapping[2].FName := '宋体';
- FontMapping[2].FSize := 11;
- end;
- procedure FixForm(AForm: TForm);
- var
- i, j : integer;
- t : TControl;
- begin
- with AForm do
- begin
- for i := 0 to ComponentCount - 1 do
- begin
- try
- t := TControl(Components[i]);
- t.left := Trunc(t.left * (Screen.width / 1024));
- t.top := Trunc(t.Top * (Screen.Height / 768));
- t.Width := Trunc(t.Width * (Screen.Width / 1024));
- t.Height := Trunc(t.Height * (Screen.Height / 768));
- except
- end; { try }
- end; { for i }
- for i:= 0 to Length(FontMapping) - 1 do
- begin
- if (Screen.Width = FontMapping[i].SWidth) and (Screen.Height = FontMapping[i].SHeight) then
- begin
- for j := 0 to ComponentCount - 1 do
- begin
- try
- TFontedControl(Components[j]).Font.Name := FontMapping[i].FName;
- TFontedControl(Components[j]).FONT.Size := FontMapping[i].FSize;
- except
- end; { try }
- end; { for j }
- end; { if }
- end; { for i }
- end; { with }
- end;
- initialization
- SetFontMapping;
- end.
- SetFontMapping 方法可以自行修改,以适应更多的分辨率。
- 调用也非常简单,如下所示:
- procedure TForm1.FormShow(Sender: TObject);
- begin
- if MessageBox(Handle,'要使用屏幕自适应吗?','提示',MB_YESNO or MB_ICONINFORMATION) = idno then Exit;
- untFixForm.FixForm(Self);
- end;
程序窗体及控件自适应分辨率
