wxPython 选项卡

虽然我们没有为 wxPython 系列大量使用面向对象,但出于简单的原因,我们无法绕过它。在本教程中,你将学习如何使用 wxPython 创建选项卡界面。

类 Mainframe 用来创建框架,就像我们在前面的例子中所做的那样。其他类是选项卡的内容。我们在主框架中创建了一个面板和笔记本(标签夹)。然后我们创建 tab 对象:

tab1 = TabOne(nb)
tab2 = TabTwo(nb)
...

我们使用以下方法附加到标签夹:

nb.AddPage(tab1, "Tab 1")
nb.AddPage(tab2, "Tab 2")
...

完整代码:

import wx
 
# Define the tab content as classes:
class TabOne(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)
        t = wx.StaticText(self, -1, "This is the first tab", (20,20))
 
class TabTwo(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)
        t = wx.StaticText(self, -1, "This is the second tab", (20,20))
 
class TabThree(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)
        t = wx.StaticText(self, -1, "This is the third tab", (20,20))
 
class TabFour(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)
        t = wx.StaticText(self, -1, "This is the last tab", (20,20))
 
 
class MainFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, title="wxPython tabs example @pythonspot.com")
 
        # Create a panel and notebook (tabs holder)
        p = wx.Panel(self)
        nb = wx.Notebook(p)
 
        # Create the tab windows
        tab1 = TabOne(nb)
        tab2 = TabTwo(nb)
        tab3 = TabThree(nb)
        tab4 = TabFour(nb)
 
        # Add the windows to tabs and name them.
        nb.AddPage(tab1, "Tab 1")
        nb.AddPage(tab2, "Tab 2")
        nb.AddPage(tab3, "Tab 3")
        nb.AddPage(tab4, "Tab 4")
 
        # Set noteboook in a sizer to create the layout
        sizer = wx.BoxSizer()
        sizer.Add(nb, 1, wx.EXPAND)
        p.SetSizer(sizer)
 
 
if __name__ == "__main__":
    app = wx.App()
    MainFrame().Show()
    app.MainLoop()

输出:
