Class API¶
Inheritance diagram for class Ticker:
Ticker(wx.Control)¶Control(parent, id=ID_ANY, pos=DefaultPosition, size=DefaultSize, style=0, validator=DefaultValidator, name=ControlNameStr) Control()
This is the base class for a control or “widget”.
__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.
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
AcceptsFocus(self)¶Non-interactive, so don’t accept focus
DoGetBestSize(self)¶Width we don’t care about, height is either -1, or the character height of our text with a little extra padding
DrawText(self, dc)¶Draws the ticker text at the current offset using the provided DC.
dc (wx.DC) – the dc to use.
GetDirection(self)¶Get the set direction.
GetFPS(self)¶Get the frames per second speed of the ticker.
GetPPF(self)¶Get pixels per frame setting.
GetText(self)¶Get the current ticker text.
IsTicking(self)¶Is the ticker ticking? ie, is the text moving?
OnErase(self, evt)¶Noop because of double buffering
Handles the wx.EVT_ERASE_BACKGROUND event for Ticker.

dir – the direction ‘rtl’ or ‘ltr’
SetFPS(self, fps)¶Adjust the update speed of the ticker.
fps (int) – frames per second.
SetPPF(self, ppf)¶Set the number of pixels per frame the ticker moves - ie, how “jumpy” it is.
ppf (int) – the pixels per frame setting.
SetText(self, text)¶Set the ticker text.
