Question

我想在我的应用程序中使用wxListbook，但我需要使用不同文本格式的多行选项。

是否可以使用wxHtmlListbox作为wxListbook中的控件以及如何执行此操作？

Answer 1

我不太确定你想要什么。您当然可以将HtmlListbox作为Listbook小部件中每个页面的子窗口小部件。您只需根据需要将其添加到每个页面元素。这是一个相当简单的例子：

import images
import wx

class MyHtmlListBox(wx.HtmlListBox):

    def OnGetItem(self, n):
        if n % 2 == 0:
            return "This is item# <b>%d</b>" % n
        else:
            return "This is item# <b>%d</b> <br>Any <font color='RED'>HTML</font> is okay." % n

        wx.Panel.__init__(self, parent)

        hlb = MyHtmlListBox(self, -1, size=(150, 250), style=wx.BORDER_SUNKEN)
        hlb.SetItemCount(50)
        hlb.SetSelection(0)

    #----------------------------------------------------------------------
    def __init__(self, parent):
        """Constructor"""
        wx.Listbook.__init__(self, parent, wx.ID_ANY, 
                             style=wx.BK_DEFAULT)
        # make an image list using the LBXX images
        il = wx.ImageList(32, 32)
        for x in range(3):
            obj = getattr(images, 'LB%02d' % (x+1))
            bmp = obj.GetBitmap()
            il.Add(bmp)
        self.AssignImageList(il)

        pages = [(MyPanel(self), "Panel One"),
                 (MyPanel(self), "Panel Two"),
                 (MyPanel(self), "Panel Three")]
        imID = 0
        for page, label in pages:
            self.AddPage(page, label, imageId=imID)
            imID += 1

        self.Bind(wx.EVT_LISTBOOK_PAGE_CHANGED, self.OnPageChanged)
        self.Bind(wx.EVT_LISTBOOK_PAGE_CHANGING, self.OnPageChanging)

    #----------------------------------------------------------------------
    def OnPageChanged(self, event):
        old = event.GetOldSelection()
        new = event.GetSelection()
        sel = self.GetSelection()
        print '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()
        print 'OnPageChanging, old:%d, new:%d, sel:%d\n' % (old, new, sel)
        event.Skip()

                          size=(700,400)
                          )
        panel = wx.Panel(self)

        notebook = ListbookDemo(panel)
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(notebook, 1, wx.ALL|wx.EXPAND, 5)
        panel.SetSizer(sizer)
        self.Layout()

        self.Show()
