在下文中一共展示了TDocument类的13个代码示例,这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞,您的评价将有助于我们的系统推荐出更棒的C++代码示例。

示例1: while

//
/// Destruct this DocManager. Close all open documents (views close with them),
/// and delete all non-static doc templates
///
/// Destroys a TDocManager object removes attached documents templates. The
/// constructor resets TDocTemplate::DocTemplateStaticHead to point to the head of
/// the static template list.
//
TDocManager::~TDocManager()
{
  // Iterate through document list, closing and deleting each
  //
  TDocument* doc;
  while ((doc = DocList.Next(0)) != 0) {
    if (doc->IsOpen())
      doc->Close();

    // NOTE: deleting the document deletes all attached views, and unlinks
    //       the document from the docmanager's document list
    //
    delete doc;

    // Flush (dispatch) any pending MDI-Child-destroy messages
    //
    GetApplication()->PumpWaitingMessages();
  }

  // Reset the 'Docmanager' pointer of static templates and delete
  // dynamic ones...
  //
  while (TemplateList) {
    TDocTemplate* tpl = TemplateList;
    TemplateList = tpl->GetNextTemplate();
    if (tpl->IsStatic())
      tpl->SetDocManager(0);
    else

示例2: NotifyViews

//
/// Performs the reverse of Commit() and cancels any changes made to the document
/// since the last commit. If clear is true, data is not reloaded for views. Revert
/// also checks all child documents and cancels any changes if all children return
/// true. When a file is closed, the document manager calls either Commit() or Revert.
/// Returns true if the operation is successful.
