Class API

class Ticker(wx.Control)

Control(parent, id=ID_ANY, pos=DefaultPosition, size=DefaultSize, style=0, validator=DefaultValidator, name=ControlNameStr) -> None Control() -> None

This is the base class for a control or “widget”.

Methods

__init__(self, parent, id=-1, text='', fgcolor=wx.BLACK, bgcolor=wx.WHITE, start=True, ppf=2, fps=20, direction='rtl', pos=wx.DefaultPosition, size=wx.DefaultSize, style=wx.NO_BORDER, name='Ticker')

Default class constructor.

Parameters:

• parent (wx.Window) – the parent

• id (integer) – an identifier for the control: a value of -1 is taken to mean a default

• text (string) – text in the ticker

• fgcolor (wx.Colour) – text/foreground color

• bgcolor (wx.Colour) – background color

• start (boolean) – if True, the ticker starts immediately

• ppf (int) – pixels per frame

• fps (int) – frames per second

• direction – direction of ticking, ‘rtl’ or ‘ltr’

• pos (wx.Point) – the control position. A value of (-1, -1) indicates a default position, chosen by either the windowing system or wxPython, depending on platform

• name – the control name
