Question

前几天，我惊讶地发现，wxPython面板上的静态文本无法选择/突出显示。我需要这样，以便用户可以复制内容。

我没有找到标志或类似内容来使StaticText组件可供选择。

import wx
app = wx.App(False)
frame = wx.Frame(None, wx.ID_ANY, "Hello, World!")
panel = wx.Panel(frame)
panel.SetBackgroundColour("#FFB6C1")
st = wx.StaticText(panel, wx.ID_ANY, "Hello, World!")
frame.Show(True)
app.MainLoop()

我找不到让StaticText可选择/可复制的方法，但这里有2个黑客可以解决问题。
1.单击鼠标右键复制到剪贴板 2. TextCtrl伪装成StaticText

import wx
class MyFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, -1)
        self.panel = wx.Panel(self)
        self.st = wx.StaticText(self.panel, wx.ID_ANY, "Hello, World! Copy me with right click",pos=(5,5))
        self.st.Bind(wx.wx.EVT_RIGHT_DOWN,self.ShowPopup)
        self.tc = wx.TextCtrl(self.panel, wx.ID_ANY, "Paste here", pos=(5,30),size=(300,20))
        self.tc2 = wx.TextCtrl(self.panel, wx.ID_ANY,"TextCtrl masquerading as StaticText - Select me",style=wx.TE_READONLY|wx.NO_BORDER,pos=(5,60),size=(300,20))
        self.tc2.SetBackgroundColour(self.panel.GetBackgroundColour())
        self.Show()

    def ShowPopup(self,event):
        popmenu = wx.Menu()
        popmenu.Append(1, "Copy this text to clipboard")
        popmenu.Bind(wx.EVT_MENU, self.Copy)
        self.panel.PopupMenu(popmenu)
        popmenu.Destroy()

    def Copy(self,event):
        clipdata = wx.TextDataObject()
        text = self.st.GetLabelText()
        clipdata.SetText(text)
        wx.TheClipboard.Open()
        wx.TheClipboard.SetData(clipdata)
        wx.TheClipboard.Close()

app = wx.App()
frame = MyFrame()
app.MainLoop()

经过几次实验后，我决定创建自定义的支持HTML的工具提示窗口。这是gist的当前版本（希望允许嵌入而不是复制此内容）：

import wx
import wx.html
import webbrowser


class HtmlPopupTransientWindow(wx.PopupTransientWindow):
    def __init__(self, parent, style, html_body_content, bgcolor, size):
        wx.PopupTransientWindow.__init__(self, parent, style)
        panel = wx.Panel(self)
        panel.SetBackgroundColour(bgcolor)

        html_window = self.HtmlWindow(panel, wx.ID_ANY, size=size)
        html_window.SetPage('<body bgcolor="' + bgcolor + '">' + html_body_content + '</body>')

        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(html_window, 0, wx.ALL, 5)
        panel.SetSizer(sizer)

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

    class HtmlWindow(wx.html.HtmlWindow):
        def OnLinkClicked(self, link):
            # get a hold of the PopupTransientWindow to close it
            self.GetParent().GetParent().Dismiss()
            webbrowser.open(link.GetHref())
