wx.lib.agw.pybusyinfo¶

PyBusyInfo constructs a busy info window and displays a message in it.

Description¶

PyBusyInfo constructs a busy info window and displays a message in it.

This class makes it easy to tell your user that the program is temporarily busy. Just create a PyBusyInfo object, and within the current scope, a message window will be shown.

For example:

busy = PyBusyInfo("Please wait, working...")

for i in xrange(10000):
    DoACalculation()

del busy

It works by creating a window in the constructor, and deleting it in the destructor. You may also want to call Yield () to refresh the window periodically (in case it had been obscured by other windows, for example).

Usage¶

Usage example:

import wx
import wx.lib.agw.pybusyinfo as PBI

class MyFrame(wx.Frame):

    def __init__(self, parent):

        wx.Frame.__init__(self, parent, -1, "PyBusyInfo Demo")

        panel = wx.Panel(self)

        b = wx.Button(panel, -1, "Test PyBusyInfo ", (50,50))
        self.Bind(wx.EVT_BUTTON, self.OnButton, b)

    def OnButton(self, event):

        message = "Please wait 5 seconds, working..."
        busy = PBI.PyBusyInfo(message, parent=self, title="Really Busy")

        wx.Yield()

        for indx in xrange(5):
            wx.MilliSleep(1000)

        del busy

# our normal wxApp-derived class, as usual

app = wx.App(0)

frame = MyFrame(None)
app.SetTopWindow(frame)
frame.Show()

app.MainLoop()
