根据另一个笔记本选项卡中的 TextCtrl() 值更改 wx.ComboBox() 中的选择
我正在使用 wx 制作一个 GUI 来运行另一个程序。我有两个笔记本选项卡:第一个用于输入,第二个用于程序的输出。我想将其设置为用户将在 InputPanel 中指示程序输出的目录,并且 OutputPanel 中的 ComboBox 将使用该目录的内容进行更新。我的代码的精简版本如下所示:
#!/usr/bin/python
import glob
import wx
class InputPanel(wx.Panel):
dirF = 0
def __init__(self, parent):
wx.Panel.__init__(self, parent=parent, id=wx.ID_ANY)
self.dirFileText = wx.StaticText(self, label="Output Directory:")
self.dirFile = wx.TextCtrl(self, value="fuda", style = wx.TE_PROCESS_ENTER)
self.Bind(wx.EVT_TEXT, self.EvtText, self.dirFile)
sizer = wx.BoxSizer(wx.HORIZONTAL)
sizer.Add(self.dirFileText, 0, wx.ALL, 2)
sizer.Add(self.dirFile, 0, wx.ALL|wx.EXPAND,2)
self.SetSizer(sizer)
sizer.Fit(self)
def EvtText(self, event):
event.GetString()
InputPanel.dirF = self.dirFile.GetValue()
class OutputPanel(wx.Panel):
def __init__(self, parent):
wx.Panel.__init__(self, parent=parent, id=wx.ID_ANY)
self.dirText = wx.StaticText(self, label="Choice?")
self.dirT = wx.ComboBox(self, choices='', style=wx.CB_READONLY)
self.dirT.SetItems(glob.glob("%s/*.dat" % (InputPanel.dirF)))
self.Bind(wx.EVT_COMBOBOX, self.onSelect, self.dirT)
sizer = wx.BoxSizer(wx.HORIZONTAL)
sizer.Add(self.dirText, 0, wx.ALL, 2)
sizer.Add(self.dirT, 0, wx.ALL|wx.EXPAND, 2)
self.SetSizer(sizer)
sizer.Fit(self)
def onSelect(self, event):
event.GetSelection()
class Notebook(wx.Notebook):
def __init__(self, parent):
wx.Notebook.__init__(self, parent, id=wx.ID_ANY, style=wx.BK_DEFAULT)
tabOne = InputPanel(self)
self.AddPage(tabOne, "Input")
tabTwo = OutputPanel(self)
self.AddPage(tabTwo, "Output")
self.Bind(wx.EVT_NOTEBOOK_PAGE_CHANGED, self.onPageChanged)
self.Bind(wx.EVT_NOTEBOOK_PAGE_CHANGING, self.onPageChanging)
def onPageChanged(self, event):
event.Skip()
def onPageChanging(self, event):
event.Skip()
class MainWindow(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, wx.ID_ANY, "nmrPipeFit", size=(600,400))
panel = wx.Panel(self)
# Setting up the menu
filemenu = wx.Menu()
menuExit = filemenu.Append(wx.ID_EXIT, "E&xit", "Exit the program")
menubar = wx.MenuBar() # Create the menubar
menubar.Append(filemenu, "&File") # Add file menu to menubar
self.SetMenuBar(menubar) # Add menubar to frame
# Set menu events
self.Bind(wx.EVT_MENU, self.OnExit, menuExit)
notebook = Notebook(panel)
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(notebook, 1, wx.ALL|wx.EXPAND, 5)
panel.SetSizer(sizer)
sizer.Fit(self)
self.Layout()
self.Show()
def OnExit(self, event):
self.Close(True) # Close the frame
if __name__== "__main__":
app=wx.PySimpleApp()
frame = MainWindow()
app.MainLoop()
我尝试了几种不同的方法来获取组合框的选择列表,以通过 InputPanel 中的目录更改进行更新,但没有运气。任何帮助将不胜感激。

I'm using wx to make a GUI for running another program. I have two Notebook tabs: the first for the input and the second for the output of my program. I would like to set it up such that the user will indicate a directory for the program output in the InputPanel, and the ComboBox in the OutputPanel will update with the contents of this directory. A stripped down version of my code looks like:
#!/usr/bin/python
import glob
import wx
class InputPanel(wx.Panel):
dirF = 0
def __init__(self, parent):
wx.Panel.__init__(self, parent=parent, id=wx.ID_ANY)
self.dirFileText = wx.StaticText(self, label="Output Directory:")
self.dirFile = wx.TextCtrl(self, value="fuda", style = wx.TE_PROCESS_ENTER)
self.Bind(wx.EVT_TEXT, self.EvtText, self.dirFile)
sizer = wx.BoxSizer(wx.HORIZONTAL)
sizer.Add(self.dirFileText, 0, wx.ALL, 2)
sizer.Add(self.dirFile, 0, wx.ALL|wx.EXPAND,2)
self.SetSizer(sizer)
sizer.Fit(self)
def EvtText(self, event):
event.GetString()
InputPanel.dirF = self.dirFile.GetValue()
class OutputPanel(wx.Panel):
def __init__(self, parent):
wx.Panel.__init__(self, parent=parent, id=wx.ID_ANY)
self.dirText = wx.StaticText(self, label="Choice?")
self.dirT = wx.ComboBox(self, choices='', style=wx.CB_READONLY)
self.dirT.SetItems(glob.glob("%s/*.dat" % (InputPanel.dirF)))
self.Bind(wx.EVT_COMBOBOX, self.onSelect, self.dirT)
sizer = wx.BoxSizer(wx.HORIZONTAL)
sizer.Add(self.dirText, 0, wx.ALL, 2)
sizer.Add(self.dirT, 0, wx.ALL|wx.EXPAND, 2)
self.SetSizer(sizer)
sizer.Fit(self)
def onSelect(self, event):
event.GetSelection()
class Notebook(wx.Notebook):
def __init__(self, parent):
wx.Notebook.__init__(self, parent, id=wx.ID_ANY, style=wx.BK_DEFAULT)
tabOne = InputPanel(self)
self.AddPage(tabOne, "Input")
tabTwo = OutputPanel(self)
self.AddPage(tabTwo, "Output")
self.Bind(wx.EVT_NOTEBOOK_PAGE_CHANGED, self.onPageChanged)
self.Bind(wx.EVT_NOTEBOOK_PAGE_CHANGING, self.onPageChanging)
def onPageChanged(self, event):
event.Skip()
def onPageChanging(self, event):
event.Skip()
class MainWindow(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, wx.ID_ANY, "nmrPipeFit", size=(600,400))
panel = wx.Panel(self)
# Setting up the menu
filemenu = wx.Menu()
menuExit = filemenu.Append(wx.ID_EXIT, "E&xit", "Exit the program")
menubar = wx.MenuBar() # Create the menubar
menubar.Append(filemenu, "&File") # Add file menu to menubar
self.SetMenuBar(menubar) # Add menubar to frame
# Set menu events
self.Bind(wx.EVT_MENU, self.OnExit, menuExit)
notebook = Notebook(panel)
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(notebook, 1, wx.ALL|wx.EXPAND, 5)
panel.SetSizer(sizer)
sizer.Fit(self)
self.Layout()
self.Show()
def OnExit(self, event):
self.Close(True) # Close the frame
if __name__== "__main__":
app=wx.PySimpleApp()
frame = MainWindow()
app.MainLoop()
I have tried several different things to get the list of choices for the combobox to update with a change in the directory from the InputPanel, but with no luck. Any help will be greatly appreciated.
Thanks, in advance,
Michael Latham

好吧,有一种丑陋的黑客方法可以做到这一点,也有一种优雅的方法可以做到这一点。事实上,可能有几个黑客。让我们看一下最常见的一个:
在笔记本的页面更改事件中,您可以告诉输出面板执行如下操作:inputPanelRef.dirFile.GetValue(),然后根据需要更新组合框的条目。您可能需要从笔记本小部件中执行此操作。
我更喜欢在面板之间传递信息的方式是使用 Pubsub。这里有一个很好的例子:

Well, there's an ugly hack way to do it and the elegant way to do it. Actually, there are probably several hacks. Let's look at one of the most common:
In the notebook's page changing event, you can tell the output panel to do something like this: inputPanelRef.dirFile.GetValue() and then update the comboboxe's entries as needed. You'll probably need to do that from the Notebook widget.
The way I prefer to pass info between panels is to use Pubsub. There's a good example here:

您可以为每个面板添加 getter 和 setter,如下所示:
您可能想要稍微清理一下,但这说明了如何做到这一点。
You can add a getter and setter for each of the panels like so:
You might want to clean this up a bit, but this illustrates how you could do it.
