我正在尝试将代码添加到笔记本页面。它在一个框架中工作正常,但在从Panel派生的笔记本页面中却没有。我需要一些帮助理解面板并帮助修复我的代码。以下是笔记本页面的代码:
class PageOne(wx.Panel):
def __init__(self, parent):
wx.Panel.__init__(self, parent)
vbox_left = wx.BoxSizer(wx.VERTICAL)
vbox_right = wx.BoxSizer(wx.VERTICAL)
panel = wx.Panel(self, -1)
hbox = wx.BoxSizer(wx.HORIZONTAL)
driveList=["D:/", "E:/"]
font = wx.Font(14, wx.SWISS, wx.NORMAL, wx.NORMAL)
label = wx.StaticText(panel, -1, "Audio Source") # Add type/name of source
label.SetFont(font)
label.SetSize(label.GetBestSize())
self.combo1 = wx.ComboBox(panel, style=wx.CB_DROPDOWN, choices=driveList)
self.listbox = wx.ListBox(panel, 1, size=(380, 220))
vbox_left.Add(label, 0, wx.BOTTOM | wx.TOP | wx.ALIGN_CENTER_HORIZONTAL, 5)
vbox_left.Add(self.combo1, 0, wx.EXPAND | wx.ALIGN_CENTER_HORIZONTAL | wx.LEFT | wx.RIGHT, 15)
vbox_left.Add(self.listbox, 1, wx.EXPAND | wx.LEFT | wx.RIGHT | wx.TOP, 15)
label = wx.StaticText(panel, -1, "Local Disk") # Add disk name
label.SetFont(font)
label.SetSize(label.GetBestSize())
self.combo2 = wx.ComboBox(panel, style=wx.CB_DROPDOWN, choices=driveList)
self.listbox = wx.ListBox(panel, 0, size=(380, 220))
vbox_right.Add(label, 0, wx.BOTTOM | wx.TOP | wx.ALIGN_CENTER_HORIZONTAL, 5)
vbox_right.Add(self.combo2, 0, wx.EXPAND | wx.ALIGN_CENTER_HORIZONTAL | wx.LEFT | wx.RIGHT, 15)
vbox_right.Add(self.listbox, 1, wx.EXPAND | wx.LEFT | wx.RIGHT | wx.TOP, 15)
hbox.Add(vbox_left, 0, wx.EXPAND | wx.LEFT, 20)
hbox.Add(vbox_right, 0, wx.EXPAND | wx.RIGHT, 20)
panel.SetSizer(hbox)
panel.Layout()
如何更改它以显示在笔记本页面上它现在只是空白。
我有第二个notebok页面,其代码是:
class PageTwo(wx.Panel):
def __init__(self, parent):
wx.Panel.__init__(self, parent)
panel = wx.Panel(self, -1)
font = wx.Font(14, wx.SWISS, wx.NORMAL, wx.NORMAL)
vbox = wx.BoxSizer(wx.VERTICAL)
label = wx.StaticText(panel, -1, "Audio Source") # Add type/name of source
label.SetFont(font)
label.SetSize(label.GetBestSize())
vbox.Add(label, 0, wx.BOTTOM | wx.TOP | wx.ALIGN_CENTER_HORIZONTAL, 5)
对于那个,我只是在右上角看到一个带有截止u的A,如我设置的文字" Audio Source"。我不明白在这些笔记本页面上的定位。如果有人可以给我一个面板和笔记本页面定位的快速解释,并帮助我改变我的代码在笔记本页面工作,这将是一个巨大的帮助。但主要是我想了解为什么我的代码不起作用。我到目前为止已经放了两个小时而且卡住了。
哦,生成笔记本的代码:
nb = wx.Notebook(panel)
# create the page windows as children of the notebook
page1 = PageOne(nb)
page2 = PageTwo(nb)
page3 = PageThree(nb)
# add the pages to the notebook with the label to show on the tab
nb.AddPage(page1, "Page 1")
nb.AddPage(page2, "Page 2")
nb.AddPage(page3, "Page 3")
hbox = wx.BoxSizer(wx.HORIZONTAL)
hbox.Add(nb, 1, wx.EXPAND)
hbox.Add(btnPanel, 0.6, wx.EXPAND | wx.RIGHT, 20)
btnPanel.SetSizer(vbox)
panel.SetSizer(hbox)
panel.Layout()
由于
编辑:我能够在笔记本中添加一个对话框并使其正常工作。但我不能让它作为一个小组工作。我想将PageOne中的代码添加到笔记本页面中,但我得到的只是一个按钮,在选项卡页面的右上角闪烁。如何将项目添加到笔记本页面?我找到了另一个例子,他们使用wx.SplitterWindow,然后他们创建了两个网格。但是,我似乎无法弄清楚如何将内容放入页面,例如列表框,树形图等。正确的方法是什么?以下是拆分器的工作代码:
import wx
import wx.grid as gridlib
class RegularPanel(wx.Panel):
def __init__(self, parent):
"""Constructor"""
wx.Panel.__init__(self, parent)
self.SetBackgroundColour("pink")
class GridPanel(wx.Panel):
def __init__(self, parent):
"""Constructor"""
wx.Panel.__init__(self, parent)
self.grid = gridlib.Grid(self, style=wx.BORDER_SUNKEN)
self.grid.CreateGrid(25,8)
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(self.grid, 1, wx.EXPAND)
self.SetSizer(sizer)
class MainPanel(wx.Panel):
def __init__(self, parent):
"""Constructor"""
wx.Panel.__init__(self, parent)
notebook = wx.Notebook(self)
page = wx.SplitterWindow(notebook)
notebook.AddPage(page, "Splitter")
hSplitter = wx.SplitterWindow(page)
panelOne = GridPanel(hSplitter)
panelTwo = GridPanel(hSplitter)
hSplitter.SplitVertically(panelOne, panelTwo)
hSplitter.SetSashGravity(0.5)
panelThree = RegularPanel(page)
page.SplitHorizontally(hSplitter, panelThree)
page.SetSashGravity(0.5)
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(notebook, 1, wx.EXPAND)
self.SetSizer(sizer)
class MainFrame(wx.Frame):
def __init__(self):
"""Constructor"""
wx.Frame.__init__(self, None, title="Nested Splitters",
size=(800,600))
panel = MainPanel(self)
self.Show()
if __name__ == "__main__":
app = wx.App(False)
frame = MainFrame()
app.MainLoop()
我尝试合并代码,尝试复制最后一个模式并集成我的列表框和树形图。但它似乎永远不会起作用。我只是希望能够在页面上放置一个树形图,在另一个页面上放置一些列表框。我错过了什么?
谢谢!

让我们从创建一个简单的笔记本开始:

import wx

class TabPanel(wx.Panel):
#----------------------------------------------------------------------
def __init__(self, parent):
""""""
wx.Panel.__init__(self, parent=parent)
colors = ["red", "blue", "gray", "yellow", "green"]
self.SetBackgroundColour(random.choice(colors))
btn = wx.Button(self, label="Press Me")
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(btn, 0, wx.ALL, 10)
self.SetSizer(sizer)
########################################################################
class DemoFrame(wx.Frame):
"""
Frame that holds all other widgets
"""
#----------------------------------------------------------------------
def __init__(self):
"""Constructor"""
wx.Frame.__init__(self, None, wx.ID_ANY,
"Notebook Tutorial",
size=(600,400)
)
panel = wx.Panel(self)
self.tab_num = 3
self.notebook = wx.Notebook(panel)
tabOne = TabPanel(self.notebook)
self.notebook.AddPage(tabOne, "Tab 1")
tabTwo = TabPanel(self.notebook)
self.notebook.AddPage(tabTwo, "Tab 2")
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(self.notebook, 1, wx.ALL|wx.EXPAND, 5)
btn = wx.Button(panel, label="Add Page")
btn.Bind(wx.EVT_BUTTON, self.addPage)
sizer.Add(btn)
panel.SetSizer(sizer)
self.Layout()
self.Show()
#----------------------------------------------------------------------
def addPage(self, event):

new_tab = TabPanel(self.notebook)
self.notebook.AddPage(new_tab, "Tab %s" % self.tab_num)
self.tab_num += 1

您将注意到我们正在为笔记本中的每个标签创建一个面板实例。笔记本是标签面板的父级。然后我们调用笔记本的AddPage
方法将面板实例与标签名称一起添加到笔记本中。
在您的示例中,您已在标签面板中创建了一个面板。这里的问题是,当它的父级也是一个面板时,这个嵌套面板不会自动展开。坦率地说,你根本不需要嵌套面板。因此,为了使其工作,只需删除嵌套面板,并使每个窗口小部件的父级成为PageOne
中的顶级面板。以下是使用PageOne
类的示例:
import wx
class PageOne(wx.Panel):
def __init__(self, parent):
wx.Panel.__init__(self, parent)
vbox_left = wx.BoxSizer(wx.VERTICAL)
vbox_right = wx.BoxSizer(wx.VERTICAL)
hbox = wx.BoxSizer(wx.HORIZONTAL)
driveList=["D:/", "E:/"]
font = wx.Font(14, wx.SWISS, wx.NORMAL, wx.NORMAL)
label = wx.StaticText(self, -1, "Audio Source") # Add type/name of source
label.SetFont(font)
label.SetSize(label.GetBestSize())
self.combo1 = wx.ComboBox(self, style=wx.CB_DROPDOWN, choices=driveList)
self.listbox = wx.ListBox(self, 1, size=(380, 220))
vbox_left.Add(label, 0, wx.BOTTOM | wx.TOP | wx.ALIGN_CENTER_HORIZONTAL, 5)
vbox_left.Add(self.combo1, 0, wx.EXPAND | wx.ALIGN_CENTER_HORIZONTAL | wx.LEFT | wx.RIGHT, 15)
vbox_left.Add(self.listbox, 1, wx.EXPAND | wx.LEFT | wx.RIGHT | wx.TOP, 15)
label = wx.StaticText(self, -1, "Local Disk") # Add disk name
label.SetFont(font)
label.SetSize(label.GetBestSize())
self.combo2 = wx.ComboBox(self, style=wx.CB_DROPDOWN, choices=driveList)
self.listbox = wx.ListBox(self, 0, size=(380, 220))
vbox_right.Add(label, 0, wx.BOTTOM | wx.TOP | wx.ALIGN_CENTER_HORIZONTAL, 5)
vbox_right.Add(self.combo2, 0, wx.EXPAND | wx.ALIGN_CENTER_HORIZONTAL | wx.LEFT | wx.RIGHT, 15)
vbox_right.Add(self.listbox, 1, wx.EXPAND | wx.LEFT | wx.RIGHT | wx.TOP, 15)
hbox.Add(vbox_left, 0, wx.EXPAND | wx.LEFT, 20)
hbox.Add(vbox_right, 0, wx.EXPAND | wx.RIGHT, 20)
self.SetSizer(hbox)
self.Layout()
########################################################################
class MyFrame(wx.Frame):
""""""
#----------------------------------------------------------------------
def __init__(self):
"""Constructor"""
wx.Frame.__init__(self, None, title='Notebooks')
panel = wx.Panel(self)
notebook = wx.Notebook(panel)
page_one = PageOne(notebook)
notebook.AddPage(page_one, 'Page 1')
main_sizer = wx.BoxSizer(wx.VERTICAL)
main_sizer.Add(notebook, 1, wx.EXPAND)
panel.SetSizer(main_sizer)
self.Show()

希望这个例子可以帮助您了解如何完成代码。
