弹出窗口内的 CheckListBox

问题描述

我想弄清楚为什么 wx.CheckListBox 在弹出窗口中不能正常工作。滚动条有效，但我无法选择任何内容。我尝试了多种类型的弹出窗口，但仍然出现相同的行为。

除了使用框架之外，还有其他解决方法的想法吗？

import wx

class MyFrame(wx.Frame):    
    def __init__(self):
        super().__init__(parent=None,title='Hello World')
        panel = wx.Panel(self)

        

        
        #self.text_ctrl = wx.TextCtrl(panel,pos=(5,5))
        my_btn = wx.Button(panel,label='Press Me',55))
        my_btn.Bind(wx.EVT_BUTTON,self.OnShowPopupTransient)

        self.Show()


    def OnShowPopupTransient(self,evt):
        sampleList = ['zero','one','two','three','four','five','six','seven','eight','nine','ten','eleven','twelve','thirteen','fourteen']
        win = TestTransientPopup(self,wx.SIMPLE_BORDER,sampleList)

        
        # Show the popup right below or above the button
        # depending on available screen space...
        btn = evt.GetEventObject()
        pos = btn.ClientToScreen( (0,0) )
        sz =  btn.GetSize()
        win.Position(pos,(0,sz[1]))

        win.Popup()

class TestTransientPopup(wx.PopupTransientwindow):
    """Adds a bit of text and mouse movement to the wx.PopupWindow"""
    def __init__(self,parent,style,sampleList):
        wx.PopupTransientwindow.__init__(self,style)
    
        panel = wx.Panel(self)
        panel.SetBackgroundColour("#FFB6C1")
        
        lb = wx.CheckListBox(panel,-1,(80,50),wx.DefaultSize,sampleList)
        
        btn = wx.Button(panel,"Press Me")
        spin = wx.SpinCtrl(panel,"Hello",size=(100,-1))
        #btn.Bind(wx.EVT_BUTTON,self.OnButton)

        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(lb,wx.ALL,5)
        sizer.Add(btn,5)
        sizer.Add(spin,5)
        panel.SetSizer(sizer)

        sizer.Fit(panel)
        sizer.Fit(self)
        self.Layout()

if __name__ == '__main__':
    app = wx.App()
    frame = MyFrame()
    app.MainLoop()

解决方法

您没有指定 wxPython 的平台或版本，但在 Linux wxPython '4.1.1 gtk3 (phoenix) wxWidgets 3.1.5' 上，以下代码似乎按预期工作。 （除非你期待别的）

import wx

class MyFrame(wx.Frame):    
    def __init__(self):
        super().__init__(parent=None,title='Hello World')
        panel = wx.Panel(self)
        my_btn = wx.Button(panel,label='Press Me',pos=(5,55))
        my_btn.Bind(wx.EVT_BUTTON,self.OnShowPopupTransient)
        self.Show()

    def OnShowPopupTransient(self,evt):
        sampleList = ['zero','one','two','three','four','five','six','seven','eight','nine','ten','eleven','twelve','thirteen','fourteen']
        win = TestTransientPopup(self,wx.BORDER_SIMPLE,sampleList)
        # Show the popup right below or above the button
        # depending on available screen space...
        btn = evt.GetEventObject()
        pos = btn.ClientToScreen( (0,0) )
        sz =  btn.GetSize()
        win.Position(pos,(0,sz[1]))
        win.Popup(focus=self)


class TestTransientPopup(wx.PopupTransientWindow):
    """Adds a bit of text and mouse movement to the wx.PopupWindow"""
    def __init__(self,parent,style,sampleList):
        wx.PopupTransientWindow.__init__(self,style)
        self.SetSize((150,300))    
        panel = wx.Panel(self,size=(150,300))
        panel.SetBackgroundColour("dark grey")
        
        self.lb = wx.CheckListBox(panel,-1,choices=sampleList)
        
        btn = wx.Button(panel,"Press Me")
        self.spin = wx.SpinCtrl(panel,"10")
        btn.Bind(wx.EVT_BUTTON,self.OnButton)

        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.lb,1,wx.ALL,5)
        sizer.Add(btn,5)
        sizer.Add(self.spin,5)
        panel.SetSizer(sizer)
        self.Layout()

    def OnButton(self,event):
        checked_items = self.lb.GetCheckedStrings()
        spin_value = self.spin.GetValue()
        print("Selected items",checked_items)
        print("Spin value",spin_value)
        self.Dismiss()

if __name__ == '__main__':
    app = wx.App()
    frame = MyFrame()
    app.MainLoop()
