在应用新的字体大小后,我正在尝试刷新我的 IDE。代码是:

procedure TEditorFontSizeController.ChangeFontSize(Delta: Integer);
var
  IdeServices: IOTAServices;
  EnvironmentOptions: IOTAEnvironmentOptions;
  CurValue: Integer;
  NewValue: Integer;
begin
  if not Supports(BorlandIDEServices, IOTAServices, IdeServices) then
    Exit;

  EnvironmentOptions := IdeServices.GetEnvironmentOptions;

  CurValue := EnvironmentOptions.Values['FontSize'];
  NewValue := CurValue + Delta;

  if (NewValue <= 7) or (NewValue >= 256) then
    Exit;

  EnvironmentOptions.Values['FontSize'] := NewValue;
  RefreshScreen;
end;

如果我从 IDE 打开编辑器选项,我可以看到新值已正确应用,但当我单击“工具选项”屏幕上的“确定”按钮时,它只会反映在 IDE 中。如何直接从代码中应用它?
