Qt 多级menu

实现如上的一个多级menu， Qt 中实现非常简单。 首先明确一个概念， QMenu表示“容器”， QAction表示具体的项。 所有上图中”其他”，“发票”等都要是QMenu， 而代充类型、有发票都要是QAction， 所以代码实现就非常简单了。

 

1. 构造

  
    

   
     
   
     1 
   
     pMenu_ 
   
     =
   
      
   
     new
   
      QMenu(tbaTableView_); 

   
     2 
   
     pBatchEditMenu_ 
   
     =
   
      
   
     new
   
      QMenu(pMenu_); 

   
     3 
   
     pBatchEditOtherMenu_ 
   
     =
   
      
   
     new
   
      QMenu(pBatchEditMenu_); 

   
     4 
   
     batchOtherBillMenu_ 
   
     =
   
      
   
     new
   
      QMenu(pBatchEditMenu_); 

   
     5 
   
     batchOtherWarrantyMenu_ 
   
     =
   
      
   
     new
   
      QMenu(pBatchEditMenu_); 

   
     6 
   
     batchOtherAutoSendMenu_ 
   
     =
   
      
   
     new
   
      QMenu(pBatchEditMenu_); 

   
     7 
   
     batchOtherRecommendMenu_ 
   
     =
   
      
   
     new
   
      QMenu(pBatchEditMenu_); 

   
     8 
   
     batchOtherDiscountMenu_ 
   
     =
   
      
   
     new
   
      QMenu(pBatchEditMenu_);
  
    

2.析构

  
    

   
     
   
     1 
   
      delete batchOtherBillMenu_; 

   
     2 
   
      delete batchOtherWarrantyMenu_; 

   
     3 
   
      delete batchOtherAutoSendMenu_; 

   
     4 
   
      delete batchOtherRecommendMenu_; 

   
     5 
   
      delete batchOtherDiscountMenu_; 

   
     6 
   
      delete pBatchEditOtherMenu_; 

   
     7 
   
      delete pBatchEditMenu_; 

   
     8 
   
      delete addItemsTimer_; 

   
     9 
   
      delete pMenu_;
  
    

注意顺序。

3. 代码实现

  
    

   
     
   
     1 
   
      pBatchEditOtherMenu_
   
     ->
   
     setTitle(tr(
   
     "
   
     其他(Q)
   
     "
   
     )); 

   
     2 
   
      batchOtherBillMenu_
   
     ->
   
     setTitle(tr(
   
     "
   
     发票
   
     "
   
     )); 

   
     3 
   
      batchOtherBillMenu_
   
     ->
   
     addAction(tr(
   
     "
   
     有发票
   
     "
   
     ),
   
     this
   
     ,SLOT(haveBillBatchEdit())); 

   
     4 
   
      batchOtherBillMenu_
   
     ->
   
     addAction(tr(
   
     "
   
     无发票
   
     "
   
     ),
   
     this
   
     ,SLOT(noBatchEdit())); 

   
     5 
   
      batchOtherRecommendMenu_
   
     ->
   
     setTitle(tr(
   
     "
   
     橱窗推荐
   
     "
   
     )); 

   
     6 
   
      batchOtherDiscountMenu_
   
     ->
   
     setTitle(tr(
   
     "
   
     会员打折
   
     "
   
     )); 

   
     7 
   
      pBatchEditMenu_
   
     ->
   
     addMenu(pBatchEditOtherMenu_); 

   
     8 
   
      pBatchEditOtherMenu_
   
     ->
   
     addMenu(batchOtherBillMenu_);
  
    

4. 快捷键以及分割线

  
    

   
     
   
     1 
   
     QAction
   
     *
   
      openDetailPage 
   
     =
   
      pMenu_
   
     ->
   
     addAction(tr(
   
     "
   
     打开宝贝页面
   
     "
   
     )); 

   
     2 
   
      openDetailPage
   
     ->
   
     setShortcut(QKeySequence(tr(
   
     "
   
     Ctrl+B
   
     "
   
     ))); 

   
     3 
   
      pMenu_
   
     ->
   
     addSeparator();
