我是wxPython的新手。如何把ListCtrl放入wxPython的ListBook中？
我可以建立的ListCtrl（wxPython中的演示）（TestVirtualList.py），
import wx
import sys
#----------------------------------------------------------------------
class TestVirtualList(wx.ListCtrl):
def __init__(self, parent, log):
wx.ListCtrl.__init__(
self, parent, -1,
style=wx.LC_REPORT|wx.LC_VIRTUAL|wx.LC_HRULES|wx.LC_VRULES
)
self.log = log
self.InsertColumn(0, "First")
self.InsertColumn(1, "Second")
self.InsertColumn(2, "Third")
self.SetColumnWidth(0, 175)
self.SetColumnWidth(1, 175)
self.SetColumnWidth(2, 175)
self.SetItemCount(100)
self.attr1 = wx.ListItemAttr()
self.attr1.SetBackgroundColour("yellow")
self.attr2 = wx.ListItemAttr()
self.attr2.SetBackgroundColour("light blue")
self.Bind(wx.EVT_LIST_ITEM_SELECTED, self.OnItemSelected)
self.Bind(wx.EVT_LIST_ITEM_ACTIVATED, self.OnItemActivated)
self.Bind(wx.EVT_LIST_ITEM_DESELECTED, self.OnItemDeselected)
def OnItemSelected(self, event):
self.currentItem = event.m_itemIndex
self.log.write('OnItemSelected: "%s", "%s", "%s", "%s"\n' %
(self.currentItem,
self.GetItemText(self.currentItem),
self.getColumnText(self.currentItem, 1),
self.getColumnText(self.currentItem, 2)))
def OnItemActivated(self, event):
self.currentItem = event.m_itemIndex
self.log.write("OnItemActivated: %s\nTopItem: %s\n" %
(self.GetItemText(self.currentItem), self.GetTopItem()))
def getColumnText(self, index, col):
item = self.GetItem(index, col)
return item.GetText()
def OnItemDeselected(self, evt):
self.log.write("OnItemDeselected: %s" % evt.m_itemIndex)
def OnGetItemText(self, item, col):
return "Item %d, column %d" % (item, col)
class TestVirtualListPanel(wx.Panel):
def __init__(self, parent, log):
wx.Panel.__init__(self, parent, -1, style=wx.WANTS_CHARS)
self.log = log
sizer = wx.BoxSizer(wx.VERTICAL)
if wx.Platform == "__WXMAC__" and \
hasattr(wx.GetApp().GetTopWindow(), "LoadDemo"):
self.useNative = wx.CheckBox(self, -1, "Use native listctrl")
self.useNative.SetValue(
not wx.SystemOptions.GetOptionInt("mac.listctrl.always_use_generic"))
self.Bind(wx.EVT_CHECKBOX, self.OnUseNative, self.useNative)
sizer.Add(self.useNative, 0, wx.ALL | wx.ALIGN_RIGHT, 4)
self.list = TestVirtualList(self, self.log)
sizer.Add(self.list, 1, wx.EXPAND)
self.SetSizer(sizer)
self.SetAutoLayout(True)
def OnUseNative(self, event):
wx.SystemOptions.SetOptionInt("mac.listctrl.always_use_generic", not event.IsChecked())
wx.GetApp().GetTopWindow().LoadDemo("ListCtrl_virtual")
#----------------------------------------------------------------------
if __name__ == "__main__":
app = wx.PySimpleApp(0)
win = wx.Frame(parent = None, title = 'Simple Editor', size = (600, 400))
log = sys.stdout
bkg = TestVirtualListPanel(win, log)
app.SetTopWindow(win)
win.Show()
app.MainLoop()
#----------------------------------------------------------------------
，我可以建立一個ListBook（TestLB.py），
import wx
import sys
colourList = [ "Aquamarine", "Black", "Blue", "Blue Violet", "Brown", "Cadet Blue",
"Coral", "Cornflower Blue", "Cyan", "Dark Grey", "Dark Green",
"Dark Olive Green",
]
#----------------------------------------------------------------------------
class TestLB(wx.Listbook):
def __init__(self, parent, id, log):
wx.Listbook.__init__(self, parent, id, style=
wx.BK_DEFAULT
#wx.BK_TOP
#wx.BK_BOTTOM
#wx.BK_LEFT
#wx.BK_RIGHT
)
self.log = log
# make an image list using the LBXX images
il = wx.ImageList(32, 32)
tsize = (32, 32)
for x in range(12):
bmp = wx.ArtProvider.GetBitmap(wx.ART_NEW, wx.ART_TOOLBAR, tsize)
il.Add(bmp)
self.AssignImageList(il)
# Now make a bunch of panels for the list book
first = True
imID = 0
for colour in colourList:
win = self.makeColorPanel(colour)
self.AddPage(win, colour, imageId=imID)
imID += 1
if imID == il.GetImageCount(): imID = 0
if first:
st = wx.StaticText(win, -1,
"I want the LISTCRL to show here,\n"
"This is the LISTCTRL %d, how can I do this???" % (imID),
wx.Point(10, 10))
first = True
self.Bind(wx.EVT_LISTBOOK_PAGE_CHANGED, self.OnPageChanged)
self.Bind(wx.EVT_LISTBOOK_PAGE_CHANGING, self.OnPageChanging)
def makeColorPanel(self, color):
p = wx.Panel(self, -1)
return p
def OnPageChanged(self, event):
old = event.GetOldSelection()
new = event.GetSelection()
sel = self.GetSelection()
self.log.write('OnPageChanged, old:%d, new:%d, sel:%d\n' % (old, new, sel))
event.Skip()
def OnPageChanging(self, event):
old = event.GetOldSelection()
new = event.GetSelection()
sel = self.GetSelection()
self.log.write('OnPageChanging, old:%d, new:%d, sel:%d\n' % (old, new, sel))
event.Skip()
#----------------------------------------------------------------------------
if __name__ == "__main__":
app = wx.PySimpleApp(0)
win = wx.Frame(parent = None, title = 'Simple Editor', size = (600, 400))
log = sys.stdout
booklist = TestLB(win, -1, log)
app.SetTopWindow(win)
win.Show()
app.MainLoop()
現在我想要將ListCtrls放入ListBook的每個頁面中，我該怎麼做？
我試圖修改OnPageChanged()功能TestLB.py：
def OnPageChanged(self, event):
old = event.GetOldSelection()
new = event.GetSelection()
sel = self.GetSelection()
self.log.write('OnPageChanged, old:%d, new:%d, sel:%d\n' % (old, new, sel))
win = self.makePanel()
sizer = wx.BoxSizer(wx.VERTICAL)
object_list = ObjectList(self, self.log)
sizer.Add(object_list, 1, wx.EXPAND)
win.SetSizer(sizer)
self.SetAutoLayout(True)
self.AddPage(win, bucketList[new], imageId=new)
event.Skip()
bucketList是list和每個元素是一個string。但它沒有按預期工作。 ListCtrl沒有顯示在Panel（ListBook的右邊部分）上，而是顯示在整個ListBook上。所以我怎麼才能讓它按預期工作。
