Question

我想要一个垂直滚动条遍布框架（Top Block）。我可以为各个面板获取垂直滚动条 -

Top Block

此处两个地块均由threads绘制class。

以下是在 gnuradio 中设置top block的代码 -

class top_block_gui(gr.top_block):
    def __init__(self, title='', size=default_gui_size):
        gr.top_block.__init__(self)
        .............
        self._frame = wx.Frame(None, title=title)
        self._panel = panel.Panel(self._frame)
        .............
    def Run(self, start=True, max_nouts=0):
        #setup app
        self._frame.Bind(wx.EVT_CLOSE, _quit)
        self._sizer = wx.BoxSizer(wx.VERTICAL)
        self._sizer.Add(self._panel, 0, wx.EXPAND)
        self._frame.SetSizerAndFit(self._sizer)
        self._frame.SetAutoLayout(True)
        self._frame.Show(True)
        self._app.SetTopWindow(self._frame)
        #start flow graph
        ..................

修改1 - 按 pss

中的方法1 中的建议 -

class top_block_gui(gr.top_block):
    def __init__(self, title='', size=default_gui_size):
        gr.top_block.__init__(self)
        .............
        self._frame = wx.Frame(None, title=title)
        self._scroll = wx.ScrolledWindow(self._frame,-1) #Added
        self._scroll.SetScrollbars(1,1,600,400) #Added
        self._panel = panel.Panel(self._scroll) #Changed
        .............
    def Run(self, start=True, max_nouts=0):
        #setup app
        self._frame.Bind(wx.EVT_CLOSE, _quit)
        self._sizer = wx.BoxSizer(wx.VERTICAL)
        self._sizer.Add(self._panel, 0, wx.EXPAND)
        self._scroll.SetSizerAndFit(self._sizer) #Changed
        self._frame.SetAutoLayout(True)
        self._frame.Show(True)
        self._app.SetTopWindow(self._frame)
        #start flow graph
        ..................

但我仍然得到与以前相同的结果。 不显示滚动条。我是否必须在任何地方将可见性设置为？

您可以使用以下任一方法：

方法1：您可以使用wx.ScrolledWindow

示例代码：

import wx
import wx.lib.scrolledpanel

class GUI(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, "Test app v1.0", style = wx.DEFAULT_FRAME_STYLE )
        self.Center()
        self.CreateStatusBar()
        mainSizer = wx.BoxSizer(wx.VERTICAL)
        self.scroll = wx.ScrolledWindow(self, -1)
        self.scroll.SetScrollbars(1, 1, 600, 400)
        panelA = wx.lib.scrolledpanel.ScrolledPanel(self.scroll, -1, style=wx.SIMPLE_BORDER, size=(300,200))
        panelA.SetupScrolling()
        panelA.SetBackgroundColour('#EEE111')
        panelB = wx.lib.scrolledpanel.ScrolledPanel(self.scroll, -1, style=wx.SIMPLE_BORDER, size=(200,200))
        panelB.SetupScrolling()
        panelB.SetBackgroundColour('#Eaa222')
        mainSizer.Add(panelA, 1, wx.ALL|wx.EXPAND, 5)
        mainSizer.Add(panelB, 1, wx.ALL|wx.EXPAND, 5)
        self.scroll.SetSizer(mainSizer)

if __name__=='__main__':
    app = wx.App(0)
    frame = GUI().Show()
    app.MainLoop()

方法2：您可以使用wx.lib.scrolledpanel.ScrolledPanel

示例：

import wx
import wx.lib.scrolledpanel

class GUI(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, "Test app v1.0", style = wx.DEFAULT_FRAME_STYLE )
        self.Center()
        self.CreateStatusBar()
        mainSizer = wx.BoxSizer(wx.VERTICAL)
        mainPanel = wx.lib.scrolledpanel.ScrolledPanel(self, -1, style=wx.SIMPLE_BORDER, size=(400, 200))
        mainPanel.SetupScrolling()
        mainPanel.SetBackgroundColour('#00000')
        panelA = wx.lib.scrolledpanel.ScrolledPanel(mainPanel, -1, style=wx.SIMPLE_BORDER, size=(300,200))
        panelA.SetupScrolling()
        panelA.SetBackgroundColour('#EEE111')
        panelB = wx.lib.scrolledpanel.ScrolledPanel(mainPanel, -1, style=wx.SIMPLE_BORDER, size=(200,200))
        panelB.SetupScrolling()
        panelB.SetBackgroundColour('#Eaa222')
        mainSizer.Add(panelA, 1, wx.ALL|wx.EXPAND, 5)
        mainSizer.Add(panelB, 1, wx.ALL|wx.EXPAND, 5)
        mainPanel.SetSizer(mainSizer)

if __name__=='__main__':
    app = wx.App(0)
    frame = GUI().Show()
    app.MainLoop()

<强>输出：
