我想有一个树形控件,我可以右键单击以创建一个弹出菜单。单击项目菜单时,将发送一个事件,其中包含树中的ItemData。我不知道该怎么做。到目前为止我只是一个简单的弹出菜单生成
# Panel
def __init__(self, ...):
# ...
self.Bind(wx.EVT_TREE_ITEM_RIGHT_CLICK, self.OnRightClick)
def OnRightClick(self, event):
popupmenu = wx.Menu()
entries = ['One', 'Two']
for entry in entries:
menuItem = popupmenu.Append(-1, entry)
如何从TreeEvent获取TreeCtrl ItemData?获得此数据后,是否需要自定义事件才能将其附加到?
编辑:很好地获取项目数据采用迂回方式。
item = event.GetItem()
itemData = self.tree.GetItemData(item).GetData()
答案 0 :(得分:2)
我在irc上得到了一些帮助。一旦我得到了项目数据,我就用lambda来包装一个事件处理程序
def OnRightClick(self, event):
"""Setup and Open a popup menu."""
# Get TreeItemData
item = event.GetItem()
itemData = self.tree.GetItemData(item).GetData()
# Create menu
popupmenu = wx.Menu()
entries = ['One', 'Two']
for entry in entries:
menuItem = popupmenu.Append(-1, entry)
wrapper = lambda event: self.OnStuff(event, itemData)
self.Bind(wx.EVT_MENU, wrapper, menuItem)
# Show menu
self.PopupMenu(popupmenu, event.GetPoint())
def OnStuff(self, event, data=None):
myEvent = events.myCustomEvent(self.GetId(), data=data)
wx.PostEvent(self, myEvent)
