:class:`PieCtrl` and :class:`ProgressPie` are simple classes that reproduce the behavior of a pie
chart.
Description
===========
:class:`PieCtrl` and :class:`ProgressPie` are simple classes that reproduce the behavior of a pie
chart. They use only pure wxPython classes/methods, without external dependencies.
:class:`PieCtrl` is somewhat a "static" control, that you may create in order to display
a simple pie chart on a :class:`Panel` or similar. :class:`ProgressPie` tries to emulate the
behavior of :class:`ProgressDialog`, but using a pie chart instead of a gauge.
Usage
=====
Usage example::
import wx
import wx.lib.agw.piectrl as PC
class MyFrame(wx.Frame):
def __init__(self, parent):
wx.Frame.__init__(self, parent, -1, "PieCtrl Demo")
panel = wx.Panel(self)
# create a simple PieCtrl with 3 sectors
mypie = PC.PieCtrl(panel, -1, wx.DefaultPosition, wx.Size(180,270))
part = PC.PiePart()
part.SetLabel("Label 1")
part.SetValue(300)
part.SetColour(wx.Colour(200, 50, 50))
mypie._series.append(part)
part = PC.PiePart()
part.SetLabel("Label 2")
part.SetValue(200)
part.SetColour(wx.Colour(50, 200, 50))
mypie._series.append(part)
part = PC.PiePart()
part.SetLabel("helloworld label 3")
part.SetValue(50)
part.SetColour(wx.Colour(50, 50, 200))
mypie._series.append(part)
# create a ProgressPie
progress_pie = PC.ProgressPie(panel, 100, 50, -1, wx.DefaultPosition,
wx.Size(180, 200), wx.SIMPLE_BORDER)
progress_pie.SetBackColour(wx.Colour(150, 200, 255))
progress_pie.SetFilledColour(wx.Colour(255, 0, 0))
progress_pie.SetUnfilledColour(wx.WHITE)
progress_pie.SetHeight(20)
main_sizer = wx.BoxSizer(wx.HORIZONTAL)
main_sizer.Add(mypie, 1, wx.EXPAND | wx.ALL, 5)
main_sizer.Add(progress_pie, 1, wx.EXPAND | wx.ALL, 5)
panel.SetSizer(main_sizer)
main_sizer.Layout()
# our normal wxApp-derived class, as usual
app = wx.App(0)
frame = MyFrame(None)
app.SetTopWindow(frame)
frame.Show()
app.MainLoop()
Methods and Settings
====================
With :class:`PieCtrl` you can:
- Create a :class:`PieCtrl` with different sectors;
- Set the sector values, colours and labels;
- Assign a legend to the :class:`PieCtrl`;
- Use an image as the :class:`PieCtrl` background;
- Change the vertical rotation (perspective) of the :class:`PieCtrl`;
- Show/hide the segment edges.
Window Styles
=============
`No particular window styles are available for this class.`
Events Processing
=================
`No custom events are available for this class.`
License And Version
===================
:class:`PieCtrl` is distributed under the wxPython license.
