在我看来,列表控件有点难以使用。基本上你需要让你在硬代码哪一列你有兴趣在这样的事情应该让你开始哪一行:
import wx
class MyForm(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, wx.ID_ANY, "List Control Tutorial")
# Add a panel so it looks the correct on all platforms
panel = wx.Panel(self, wx.ID_ANY)
self.index = 0
self.current_selection = None
self.list_ctrl = wx.ListCtrl(panel, size=(-1,100),
style=wx.LC_REPORT
|wx.BORDER_SUNKEN
)
self.list_ctrl.InsertColumn(0, 'Subject')
self.list_ctrl.InsertColumn(1, 'Due')
self.list_ctrl.InsertColumn(2, 'Location', width=125)
self.list_ctrl.Bind(wx.EVT_LIST_ITEM_SELECTED, self.on_item_selected)
btn = wx.Button(panel, label="Add Line")
btn.Bind(wx.EVT_BUTTON, self.add_line)
data_getter_btn = wx.Button(panel, label='Get all data')
data_getter_btn.Bind(wx.EVT_BUTTON, self.on_get_data)
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(self.list_ctrl, 0, wx.ALL|wx.EXPAND, 5)
sizer.Add(btn, 0, wx.ALL|wx.CENTER, 5)
sizer.Add(data_getter_btn, 0, wx.ALL|wx.CENTER, 5)
panel.SetSizer(sizer)
def add_line(self, event):
line = "Line %s" % self.index
self.list_ctrl.InsertStringItem(self.index, line)
self.list_ctrl.SetStringItem(self.index, 1, "01/19/2010")
self.list_ctrl.SetStringItem(self.index, 2, "USA")
self.index += 1
def on_item_selected(self, event):
self.current_selection = event.m_itemIndex
def on_get_data(self, event):
if self.current_selection:
print self.current_selection
item = self.list_ctrl.GetItem(itemId=self.current_selection, col=2)
print item.GetText()
#----------------------------------------------------------------------
# Run the program
if __name__ == "__main__":
app = wx.App(False)
frame = MyForm()
frame.Show()
app.MainLoop()
上面的代码将打印出当前选择(行号)和第三栏的文字。如果你想打印出所有的行和列的文本,那么你可以做这样的事情:
import wx
########################################################################
class MyForm(wx.Frame):
#----------------------------------------------------------------------
def __init__(self):
wx.Frame.__init__(self, None, wx.ID_ANY, "List Control Tutorial")
# Add a panel so it looks the correct on all platforms
panel = wx.Panel(self, wx.ID_ANY)
self.index = 0
self.list_ctrl = wx.ListCtrl(panel, size=(-1,100),
style=wx.LC_REPORT
|wx.BORDER_SUNKEN
)
self.list_ctrl.InsertColumn(0, 'Subject')
self.list_ctrl.InsertColumn(1, 'Due')
self.list_ctrl.InsertColumn(2, 'Location', width=125)
btn = wx.Button(panel, label="Add Line")
btn2 = wx.Button(panel, label="Get Data")
btn.Bind(wx.EVT_BUTTON, self.add_line)
btn2.Bind(wx.EVT_BUTTON, self.get_data)
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(self.list_ctrl, 0, wx.ALL|wx.EXPAND, 5)
sizer.Add(btn, 0, wx.ALL|wx.CENTER, 5)
sizer.Add(btn2, 0, wx.ALL|wx.CENTER, 5)
panel.SetSizer(sizer)
#----------------------------------------------------------------------
def add_line(self, event):
line = "Line %s" % self.index
self.list_ctrl.InsertStringItem(self.index, line)
self.list_ctrl.SetStringItem(self.index, 1, "01/19/2010")
self.list_ctrl.SetStringItem(self.index, 2, "USA")
self.index += 1
#----------------------------------------------------------------------
def get_data(self, event):
""""""
count = self.list_ctrl.GetItemCount()
cols = self.list_ctrl.GetColumnCount()
for row in range(count):
for col in range(cols):
item = self.list_ctrl.GetItem(itemId=row, col=col)
print item.GetText()
#----------------------------------------------------------------------
# Run the program
if __name__ == "__main__":
app = wx.App(False)
frame = MyForm()
frame.Show()
app.MainLoop()
更简单的方法来完成这样的事情,虽然将物体与每一行相关联。这里有一个例子:
import wx
########################################################################
class Car(object):
""""""
#----------------------------------------------------------------------
def __init__(self, make, model, year, color="Blue"):
"""Constructor"""
self.make = make
self.model = model
self.year = year
self.color = color
########################################################################
class MyPanel(wx.Panel):
""""""
#----------------------------------------------------------------------
def __init__(self, parent):
"""Constructor"""
wx.Panel.__init__(self, parent)
rows = [Car("Ford", "Taurus", "1996"),
Car("Nissan", "370Z", "2010"),
Car("Porche", "911", "2009", "Red")
]
self.list_ctrl = wx.ListCtrl(self, size=(-1,100),
style=wx.LC_REPORT
|wx.BORDER_SUNKEN
)
self.list_ctrl.Bind(wx.EVT_LIST_ITEM_SELECTED, self.onItemSelected)
self.list_ctrl.InsertColumn(0, "Make")
self.list_ctrl.InsertColumn(1, "Model")
self.list_ctrl.InsertColumn(2, "Year")
self.list_ctrl.InsertColumn(3, "Color")
index = 0
self.myRowDict = {}
for row in rows:
self.list_ctrl.InsertStringItem(index, row.make)
self.list_ctrl.SetStringItem(index, 1, row.model)
self.list_ctrl.SetStringItem(index, 2, row.year)
self.list_ctrl.SetStringItem(index, 3, row.color)
self.myRowDict[index] = row
index += 1
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(self.list_ctrl, 0, wx.ALL|wx.EXPAND, 5)
self.SetSizer(sizer)
#----------------------------------------------------------------------
def onItemSelected(self, event):
""""""
currentItem = event.m_itemIndex
car = self.myRowDict[currentItem]
print car.make
print car.model
print car.color
print car.year
########################################################################
class MyFrame(wx.Frame):
""""""
#----------------------------------------------------------------------
def __init__(self):
"""Constructor"""
wx.Frame.__init__(self, None, wx.ID_ANY, "List Control Tutorial")
panel = MyPanel(self)
self.Show()
#----------------------------------------------------------------------
if __name__ == "__main__":
app = wx.App(False)
frame = MyFrame()
app.MainLoop()
很坦率地说,我真的不再使用ListCtrl了。我更喜欢使用ObjectListView,因为它看起来更容易使用,并提供了更多的功能。这里有几个环节:
我想在用户单击按钮时打印D列。所以我必须这样绑定按钮:self.plot_btn.Bind(wx.EVT_BUTTON,self.OnPlot,self.plot_btn)现在,如果我按照你所说的那样定义onplot,它会给我错误CommandEvent没有属性'GetIndex ' –
因为你说你的绑定语句是'self.Bind(wx.EVT_LIST_ITEM_SELECTED,self.OnPlot,self.list)'我假定点击发生在'ListCtrl'' self.list'上,因为按钮没有有一个'事件',而ListCtrl呢。你将不得不发布你的代码,而不仅仅是这个片段。我想你必须得到按钮事件来激发一个'listCtrl'事件,这是一种奇怪的方式来安排事情,但不是不可能做到。 –
看到我编辑的答案 –
