wxpython：设置最小窗口宽度 / 调整大小时按钮消失

Question

我有一个主窗口，里面有两个垂直排列的面板；上面的面板里有文本和按钮（按钮在面板内是水平排列的），而下面的面板则包含一些可以轻松调整大小的内容。我想设置这个窗口的最小宽度，这样当我把窗口缩小时，上面的按钮和其他内容不会被遮住，因为这些内容必须始终可见。经过大量搜索，似乎没有现成的wx函数可以做到这一点（我找到的最接近的办法是self.SetMinSize(self.GetSize())，但这也限制了窗口的高度，而我并不想这样）。我也想知道是否有方法可以设置窗口的最小高度（不过我想这和宽度的设置应该类似）。

另一种方法是找到一种方式，当按钮没有更多空间可以移动以适应窗口大小的变化时，阻止窗口宽度的进一步缩小（这有点像菜单栏，菜单会堆叠起来，直到没有更多空间为止）。

有没有简单的方法可以做到这一点，还是说这需要更多的代码来定制一个框架类，然后在主窗口中使用？谢谢！

这里是代码，以备不时之需：

class MainWindow(wx.Frame):
  def __init__(self, parent, title):
    wx.Frame.__init__(self, parent, title=title, size=(850, 800))
    self.exedir = os.getcwd() 
    self.dirname= ''
    #self.SetMinSize(self.GetSize())

    #Set up the initial frames.   
    self.panel1 = wx.Panel(self)  #Create a new panel
    self.panel2 = wx.Panel(self)  #Create a panel for the resulting search
    self.nb = wx.Notebook(self.panel2, size=(wx.EXPAND, 0))

    mainTab = MainTab(self.nb)
    self.nb.AddPage(mainTab, "Main")

    #if page2 is not None:
        #self.nb.AddPage(page2, "Employees")
        #self.nb.Update(self)
    #self.nb.AddPage(page2, "Employees")
    #nb.AddPage(page3, "Tasks")

    self.statusText = wx.StaticText(self.panel1, label="Status: ", size = (50,20))
    self.result = wx.StaticText(self.panel1, label="No Connection", size = (575,20))
    self.result.SetForegroundColour(wx.BLACK) 

    self.buttonConnect = wx.Button(self.panel1, label="Connect")
    self.buttonDisconnect = wx.Button(self.panel1, label="Disconnect")
    self.buttonDisconnect.Disable() #Originally disabled

    self.CreateStatusBar() # A Statusbar in the bottom of the window

    taskmenuViewTasks =  taskmenu.Append(wx.ID_VIEW_LIST, "&View list of Employee Tasks"," View all the employee's tasks in the database")

    helpmenu = wx.Menu()
    helpmenuHelp = helpmenu.Append(wx.ID_HELP, "&Help"," Instructions on how to use program")
    helpmenuAbout = helpmenu.Append(wx.ID_ABOUT, "&About"," Information about the program")

    exitmenu = wx.Menu()
    exitmenuExit = exitmenu.Append(wx.ID_EXIT, "&Exit"," Quit the program safely")

    employeemenu = wx.Menu()
    employeemenuAddAll = employeemenu.Append(wx.ID_REPLACE_ALL, "&Fill Employee database from .csv"," Fill the entire database form a .csv file")
    employeemenuBackup = employeemenu.Append(wx.ID_DUPLICATE, "&Backup Employee database to .csv"," Backup the database to a .csv file")
    employeemenuViewall = employeemenu.Append(wx.ID_VIEW_LIST, "&View list of Employees"," View all the employees in the database")
    employeemenuAdd = employeemenu.Append(wx.ID_FIND, "&Add Employee"," Add Employee to the database")
    employeemenuModify = employeemenu.Append(wx.ID_REPLACE, "&Modify Employee Fields"," Modify an existing Employee")
    employeemenuDelete = employeemenu.Append(wx.ID_DELETE, "&Delete Employee","Remove and Employee from the database")


    # Creating the menubar.
    self.menuBar = wx.MenuBar()
    self.menuBar.Append(configmenu,"&Config") # Adding the "configmenu" to the MenuBar

    self.menuBar.Append(employeemenu,"&Employees") # Adding the "Employees" to the MenuBar
    self.menuBar.Append(helpmenu,"&Help") # Adding the "Help" to the MenuBar
    self.menuBar.Append(exitmenu,"&Quit") # Adding the "Quit" to the MenuBar

    self.SetMenuBar(self.menuBar)  # Adding the MenuBar to the Frame content.
    self.menuBar.EnableTop(pos=2,enable=False)  #Disable the EMPLOYEE menubar until it is ready
    self.menuBar.EnableTop(pos=1,enable=False)
    # Events for Config
    self.Bind(wx.EVT_MENU, self.OnConfig, configmenuConfig)

    #Set the sizer for the first panel
    panelSizer = wx.BoxSizer(wx.HORIZONTAL)
    panelSizer.Add(self.statusText, proportion=0)
    panelSizer.Add(self.result, proportion=0)
    panelSizer.Add(self.buttonConnect, proportion=0)
    panelSizer.Add(self.buttonDisconnect, proportion=0)

    self.panel1.SetSizer(panelSizer) #Set the panel1 sizer
    self.panel1.Layout()

    #Set the sizer for the second panel
    panel2Sizer = wx.BoxSizer(wx.HORIZONTAL)
    panel2Sizer.Add(self.nb, 0, wx.EXPAND)
    #panel2Sizer.Add(self.grid, 1, wx.EXPAND)
    self.panel2.SetSizerAndFit(panel2Sizer)
    #self.panel2.Layout

    # Set sizer for the  main frame, so we can change frame size to match widgets
    self.windowSizer = wx.BoxSizer(wx.VERTICAL)
    self.windowSizer.Add(self.panel1, proportion=0)  
    self.windowSizer.Add(self.panel2, wx.EXPAND)  

    self.SetSizer(self.windowSizer)
    self.Layout()
    self.Show()

我觉得防止用户把窗口缩得太小的一个简单方法就是使用它的 SetSizeHints 方法。你只需要传入最小宽度/高度和最大宽度/高度。

这里有个简单的例子：

self.SetSizeHints(400,400,1200,1200)

你可以在 文档 中了解更多关于这个方法的信息。我还找到一个类似的问题，里面有一些有趣的信息：
