Question

I am building a Python program that searches things on a remote website. Sometimes the operation takes many seconds and I believe that the user will not notice the status bar message "Search Operation in progress". Therefore, I would like to change the mouse cursor to highlight that the program is still waiting for a result.

这是我使用的方法:

def OnButtonSearchClick( self, event ):
        """
        If there is text in the search text, launch a SearchOperation.
        """
        searched_value = self.m_search_text.GetValue()

        if not searched_value:
            return

        # clean eventual previous results
        self.EnableButtons(False)
        self.CleanSearchResults()

        operations.SearchOperation(self.m_frame, searched_value)

我在最后一行之前尝试了两种不同的做法:

wx.BeginBusyCursor()
self.m_frame.SetCursor(wx.StockCursor(wx.CURSOR_WAIT))

他们都没有工作。

我在GNU/HCH下使用KE。这也不是在格诺梅下工作的。

任何方面? 谢谢。

我向牛津饥荒的制造者罗宾·邓恩询问了这一情况,它喜欢这样做,但并没有结果。然而,如果你打电话给小组SetaCursor(),那么DOES的工作就是这样说的。在这方面,你可以尝试:

import wx

########################################################################
class MyForm(wx.Frame):

    #----------------------------------------------------------------------
    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, "Tutorial")

        # Add a self.panel so it looks the correct on all platforms
        self.panel = wx.Panel(self, wx.ID_ANY)

        btn = wx.Button(self.panel, label="Change Cursor")
        btn.Bind(wx.EVT_BUTTON, self.changeCursor)
        sizer = wx.BoxSizer(wx.HORIZONTAL)
        sizer.Add(btn)
        self.panel.SetSizer(sizer)

    #----------------------------------------------------------------------
    def changeCursor(self, event):
        """"""
        myCursor= wx.StockCursor(wx.CURSOR_WAIT)
        self.panel.SetCursor(myCursor)


#----------------------------------------------------------------------
# Run the program
if __name__ == "__main__":
    app = wx.PySimpleApp()
    frame = MyForm().Show()
    app.MainLoop()
