DevExpress换肤

procedure TForm1.cxComboBox1PropertiesChange(Sender: TObject);
begin
  // 这个地方必须是UserSkin,不然不会起作用
  dxSkinController1.SkinName := 'UserSkin';
  dxSkinsUserSkinLoadFromFile('AllSkins.skinres', cxComboBox1.EditText);
end;

procedure TForm1.dxSkinController1SkinForm(Sender: TObject; AForm: TCustomForm;
  var ASkinName: string; var UseSkin: Boolean);
begin
  // Simon自己认为这一句不应该要，要了窗口就不能跟着变，
  //而且dxSkinController要在所有cx控件添加前添加，否则控件皮肤不受拜你控制。
  // UseSkin := false;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  cxComboBox1.Properties.Items.Clear;
  dxSkinsUserSkinPopulateSkinNames('AllSkins.skinres',cxComboBox1.Properties.Items);
  cxComboBox1.ItemIndex := 0;
end;

AllSkins.skinres所有的皮肤集成包在DevExpress\ExpressSkins Library\Binary Skin Files目录下，需要时放到应用程序同目录下或加载时修改路径

如果找不到dxSkinsUserSkinPopulateSkinNames需要引用dxSkinsDefaultPainters
