树状视图和列表存储(List Stores)

#Here are some variables that can be reused later
self.cWine = 0
self.cWinery = 1
self.cGrape = 2
self.cYear = 3
		
self.sWine = "Wine"

self.sGrape = "Grape"
self.sYear = "Year"		
				
#Get the treeView from the widget Tree
self.wineView = self.wTree.get_widget("wineView")
#Add all of the List Columns to the wineView
self.AddWineListColumn(self.sWine, self.cWine)
self.AddWineListColumn(self.sWinery, self.cWinery)
self.AddWineListColumn(self.sGrape, self.cGrape)
self.AddWineListColumn(self.sYear, self.cYear)

#Create the listStore Model to use with the wineView
self.wineList = gtk.ListStore(str, str, str, str)
#Attatch the model to the treeView
self.wineView.set_model(self.wineList)

把所有合并到一起  

 我们要做的最后一件事是完成pyWine类中的OnAddWine函数(从菜单或工具栏按钮调用). 这个函数很简单:

OnAddWine(self, widget): """Called when the use wants to add a wine""" #Create the dialog, show it, and store the results wineDlg = wineDialog(); result,newWine = wineDlg.run() if (result == gtk.RESPONSE_OK): """The user clicked Ok, so let's add this wine to the wine list""" self.wineList.append(newWine.getList())

   这里我们创建了一个wineDialog的实例, 然后运行它并把用户输入的酒的信息保存.然后我们检查result是不是gtk_RESPONSE_OK(用户点击了Ok按钮), 如果是我们就把酒的信息添加到gtk_ListStore中, 它会自动的在gtk_TreeView中显示出来因此它们是连接在一起的.
   在wine类中我使用简单的getList函数以使阅读代码变得简单一些:

def getList(self): """This function returns a list made up of the wine information. It is used to add a wine to the wineList easily""" return [self.wine, self.winery, self.grape, self.year]

   到这里这个简单程序就算完成了, 尽管它不保存任何信息或是任何和它类似的信息, 但是它确实描述了一些创建一个完整pyGTK 应用程序的基本步骤.
