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:
