wxPython:在同一框架中显示多个小部件 [英] wxPython: displaying multiple widgets in same frame

问题描述

我希望能够在单个框架中显示Notebook和TxtCtrl wx小部件.以下是改编自wxpython Wiki的示例；是否可以更改其布局(例如使用wx.SplitterWindow之类的内容)，以在同一帧中的Notebook下面显示文本框?

I would like to be able to display Notebook and a TxtCtrl wx widgets in a single frame. Below is an example adapted from the wxpython wiki; is it possible to change their layout (maybe with something like wx.SplitterWindow) to display the text box below the Notebook in the same frame?

import wx
import wx.lib.sheet as sheet

class MySheet(sheet.CSheet):
    def __init__(self, parent):
        sheet.CSheet.__init__(self, parent)

        self.SetLabelBackgroundColour('#CCFF66')
        self.SetNumberRows(50)
        self.SetNumberCols(50)


class Notebook(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, size=(600, 600))
        menubar = wx.MenuBar()
        file = wx.Menu()
        file.Append(101, 'Quit', '' )
        menubar.Append(file, "&File")
        self.SetMenuBar(menubar)
        wx.EVT_MENU(self, 101, self.OnQuit)
        nb = wx.Notebook(self, -1, style=wx.NB_BOTTOM)
        self.sheet1 = MySheet(nb)
        self.sheet2 = MySheet(nb)
        self.sheet3 = MySheet(nb)
        nb.AddPage(self.sheet1, "Sheet1")
        nb.AddPage(self.sheet2, "Sheet2")
        nb.AddPage(self.sheet3, "Sheet3")
        self.sheet1.SetFocus()
        self.StatusBar()

    def StatusBar(self):
        self.statusbar = self.CreateStatusBar()

    def OnQuit(self, event):
        self.Close()


class MyFrame(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, wx.DefaultPosition, wx.Size(450, 400))
        self.text = wx.TextCtrl(self, -1, style = wx.TE_MULTILINE)
        self.Center()

class MyApp(wx.App):
    def OnInit(self):
        frame = Notebook(None, -1, 'notebook.py')
        frame.Show(True)
        frame.Center()
        frame2 = MyFrame(None, -1, '')
        frame2.Show(True)
        self.SetTopWindow(frame2)
        return True


app = MyApp(0)
app.MainLoop()

推荐答案

实际上，使两个小部件出现在同一框架上很容易.您应该使用大小调整器来完成此操作.

Making two widgets appear on the same frame is easy, actually. You should use sizers to accomplish this.

在您的示例中，您可以将Notebook类的实现更改为以下内容:

In your example, you can change your Notebook class implementation to something like this:

class Notebook(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, size=(600, 600))
        menubar = wx.MenuBar()
        file = wx.Menu()
        file.Append(101, 'Quit', '' )
        menubar.Append(file, "&File")
        self.SetMenuBar(menubar)
        wx.EVT_MENU(self, 101, self.OnQuit)
        nb = wx.Notebook(self, -1, style=wx.NB_BOTTOM)
        self.sheet1 = MySheet(nb)
        self.sheet2 = MySheet(nb)
        self.sheet3 = MySheet(nb)
        nb.AddPage(self.sheet1, "Sheet1")
        nb.AddPage(self.sheet2, "Sheet2")
        nb.AddPage(self.sheet3, "Sheet3")
        self.sheet1.SetFocus()
        self.StatusBar()
        # new code begins here:
        # add your text ctrl:
        self.text = wx.TextCtrl(self, -1, style = wx.TE_MULTILINE)
        # create a new sizer for both controls:
        sizer = wx.BoxSizer(wx.VERTICAL)
        # add notebook first, with size factor 2:
        sizer.Add(nb, 2)
        # then text, size factor 1, maximized
        sizer.Add(self.text, 1, wx.EXPAND)
        # assign the sizer to Frame:
        self.SetSizerAndFit(sizer)

仅__init__方法被更改.请注意，您可以通过更改Add方法的第二个参数来操纵笔记本和文本控件之间的比例.

Only the __init__ method is changed. Note that you can manipulate the proportions between the notebook and text control by changing the second argument of the Add method.

您可以从官方 Sizer概述文章中了解有关定尺器的更多信息.
