在我看來,列表控件有點難以使用。基本上你需要讓你在硬代碼哪一列你有興趣在這樣的事情應該讓你開始哪一行:
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()
上面的代碼將打印出當前選擇(行號)和第三欄的文字。如果你想打印出所有的行和列的文本,那麼你可以做這樣的事情:
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()
更簡單的方法來完成這樣的事情,雖然將物體與每一行相關聯。這裏有一個例子:
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()
很坦率地說,我真的不再使用ListCtrl了。我更喜歡使用ObjectListView,因爲它看起來更容易使用,並提供了更多的功能。這裏有幾個環節:
我想在用戶單擊按鈕時打印D列。所以我必須這樣綁定按鈕:self.plot_btn.Bind(wx.EVT_BUTTON,self.OnPlot,self.plot_btn)現在,如果我按照你所說的那樣定義onplot,它會給我錯誤CommandEvent沒有屬性'GetIndex ' –
因爲你說你的綁定語句是'self.Bind(wx.EVT_LIST_ITEM_SELECTED,self.OnPlot,self.list)'我假定點擊發生在'ListCtrl'' self.list'上,因爲按鈕沒有有一個'事件',而ListCtrl呢。你將不得不發佈你的代碼,而不僅僅是這個片段。我想你必須得到按鈕事件來激發一個'listCtrl'事件,這是一種奇怪的方式來安排事情,但不是不可能做到。 –
