==========================================================================================================================================

:class:`~wx.lib.agw.pyprogress.PyProgress` is similar to :class:`ProgressDialog` in indeterminated mode, but with a
different gauge appearance and a different spinning behavior.


Description
===========

:class:`PyProgress` is similar to :class:`ProgressDialog` in indeterminated mode, but with a
different gauge appearance and a different spinning behavior. The moving gauge
can be drawn with a single solid colour or with a shading gradient foreground.
The gauge background colour is user customizable.

The bar does not move always from the beginning to the end as in :class:`ProgressDialog`
in indeterminated mode, but spins cyclically forward and backward.

Other options include:

- Possibility to change the proportion between the spinning bar and the
  entire gauge, so that the bar can be longer or shorter (the default is 20%);
- Modifying the number of steps the spinning bar performs before a forward
  (or backward) loop reverses.

:class:`PyProgress` can optionally display a ``Cancel`` button, and a :class:`StaticText` which
outputs the elapsed time from the starting of the process.


Usage
=====

Usage example::

    import wx
    import wx.lib.agw.pyprogress as PP

    # Our normal wxApp-derived class, as usual
    app = wx.App(0)

    dlg = PP.PyProgress(None, -1, "PyProgress Example",
                        "An Informative Message",
                        agwStyle=wx.PD_APP_MODAL | wx.PD_ELAPSED_TIME)

    dlg.SetGaugeProportion(0.2)
    dlg.SetGaugeSteps(50)
    dlg.SetGaugeBackground(wx.WHITE)
    dlg.SetFirstGradientColour(wx.WHITE)
    dlg.SetSecondGradientColour(wx.BLUE)

    max = 400
    keepGoing = 1
    count = 0

    while keepGoing and count < max:
        count += 1
        wx.MilliSleep(30)

        if count >= max // 2:
            keepGoing = dlg.UpdatePulse("Half-time!")
        else:
            keepGoing = dlg.UpdatePulse()

    dlg.Destroy()

    app.MainLoop()



Supported Platforms
===================

:class:`PyProgress` has been tested on the following platforms:
  * Windows (Windows XP);
  * Linux Ubuntu (Dapper 6.06)


Window Styles
=============

This class supports the following window styles:

=================== =========== ==================================================
Window Styles       Hex Value   Description
=================== =========== ==================================================
``PD_CAN_ABORT``            0x1 This flag tells the dialog that it should have a ``Cancel`` button which the user may press. If this happens, the next call to `Update` will return ``False``.
``PD_APP_MODAL``            0x2 Make the progress dialog modal. If this flag is not given, it is only 'locally' modal - that is the input to the parent window is disabled, but not to the other ones.
``PD_AUTO_HIDE``            0x4 Causes the progress dialog to disappear from screen as soon as the maximum value of the progress meter has been reached.
``PD_ELAPSED_TIME``         0x8 This flag tells the dialog that it should show elapsed time (since creating the dialog).
