Просмотр 'wx. ScrolledPanel' с колесом мыши и клавишами со стрелками

Here's an example that should do what you want, I hope. (Edit: In retrospect, this doesnt' quite work, for example, when there are two scrolled panels... I'll leave it up here though so peole can downvote it or whatever.) Basically I put everything in a panel inside the frame (generally a good idea), and then set the focus to this main panel.

import wx
import wx, wx.lib.scrolledpanel

class MyFrame(wx.Frame):
    def __init__(self, *args, **kwargs):
        wx.Frame.__init__(self, *args, **kwargs)
        main_panel = wx.Panel(self, -1)
        main_panel.SetBackgroundColour((150, 100, 100))
        self.main_panel = main_panel

        scrolled_panel = \
            wx.lib.scrolledpanel.ScrolledPanel(parent=main_panel, id=-1)
        scrolled_panel.SetupScrolling()
        self.scrolled_panel = scrolled_panel

        cpanel = wx.Panel(main_panel, -1)
        cpanel.SetBackgroundColour((100, 150, 100))
        b = wx.Button(cpanel, -1, size=(40,40))
        self.Bind(wx.EVT_BUTTON, self.OnClick, b)
        self.b = b

        text = "Ooga booga\n" * 50
        static_text=wx.StaticText(scrolled_panel, -1, text)
        main_sizer=wx.BoxSizer(wx.VERTICAL)
        main_sizer.Add(scrolled_panel, 1, wx.EXPAND)
        main_sizer.Add(cpanel, 1, wx.EXPAND)
        main_panel.SetSizer(main_sizer)

        text_sizer=wx.BoxSizer(wx.VERTICAL)
        text_sizer.Add(static_text, 1, wx.EXPAND)
        scrolled_panel.SetSizer(text_sizer)

        self.main_panel.SetFocus()

        self.Show()

    def OnClick(self, evt):
        print "click"


if __name__=="__main__":
    class MyApp(wx.App):

        def OnInit(self):
            frame = MyFrame(None, -1)
            frame.Show(True)
            self.SetTopWindow(frame)
            return True
    app = MyApp(0)
    app.MainLoop()

For keyboard control, like setting action from the home key, I think you'll need to bind to those events, and respond appropriately, such as using mypanel.Scroll(0,0) for the home key (and remember to call evt.Skip() for the keyboard events you don't act on). (Edit: I don't think there are any default key bindings for scrolling. I'm not sure I'd want any either, for example, what should happen if there's a scrolled panel within a scrolled panel?)

Проблема в окне Фрейм получает фокус, а дочерняя панель не получает Сосредоточьтесь (на ubuntu linux все работает нормально). Обходной путь может быть таким же простым, как перенаправить событие фокуса кадра, чтобы установить фокус на панель, например

import wx, wx.lib.scrolledpanel

class MyFrame(wx.Frame):
    def __init__(self, *args, **kwargs):
        wx.Frame.__init__(self, *args, **kwargs)

        self.panel = scrolled_panel = \
            wx.lib.scrolledpanel.ScrolledPanel(parent=self, id=-1)
        scrolled_panel.SetupScrolling()

        text = "Ooga booga\n" * 50
        static_text=wx.StaticText(scrolled_panel, -1, text)
        sizer=wx.BoxSizer(wx.VERTICAL)
        sizer.Add(static_text, wx.EXPAND, 0)

        scrolled_panel.SetSizer(sizer)

        self.Show()

        self.panel.SetFocus()
        scrolled_panel.Bind(wx.EVT_SET_FOCUS, self.onFocus)

    def onFocus(self, event):
        self.panel.SetFocus()

if __name__=="__main__":
    app = wx.PySimpleApp()
    my_frame=MyFrame(None, -1)
    app.MainLoop()

или onmouse переместитесь на панель, установите на нее фокус, и все клавиши + колесо мыши начнут работать, например,

import wx, wx.lib.scrolledpanel

class MyFrame(wx.Frame):
    def __init__(self, *args, **kwargs):
        wx.Frame.__init__(self, *args, **kwargs)

        self.panel = scrolled_panel = \
            wx.lib.scrolledpanel.ScrolledPanel(parent=self, id=-1)
        scrolled_panel.SetupScrolling()

        scrolled_panel.Bind(wx.EVT_MOTION, self.onMouseMove)

        text = "Ooga booga\n" * 50
        static_text=wx.StaticText(scrolled_panel, -1, text)
        sizer=wx.BoxSizer(wx.VERTICAL)
        sizer.Add(static_text, wx.EXPAND, 0)

        scrolled_panel.SetSizer(sizer)

        self.Show()

    def onMouseMove(self, event):
        self.panel.SetFocus()

if __name__=="__main__":
    app = wx.PySimpleApp()
    my_frame=MyFrame(None, -1)
    app.MainLoop()
