overview = """\
The following was gleaned as best I could from the wxWindows
source, which was a bit reluctant to reveal its secrets. My appologies if
I missed anything - jmg
LEDNumberCtrl( parent, id=-1, pos=wx.DefaultPosition,
size=wx.DefaultSize, style=LED_ALIGN_LEFT | LED_DRAW_FADED)
This is a control that simulates an LED clock display. It only accepts
numeric input.
Styles
- LED_ALIGN_LEFT
- Align to the left.
- LED_ALIGN_RIGHT
- Align to the right.
- LED_ALIGN_CENTER
- Center on display.
- LED_DRAW_FADED
- Not implemented.
Methods (and best guesses at what they do)
- GetAlignment()
- Returns the alignment attribute for the control.
- GetDrawFaded()
- Returns the DrawFaded attribute for the control.
- GetValue()
- Returns the current value of the control.
- SetAlignment(alignment)
- Set the alignment attribute for the control.
- SetDrawFaded(value)
- Set the DrawFaded attribute for the control.
- SetValue(number)
- Set the value for the control. Only numeric values are accepted.
Additionally, several methods of wx.Window are available as well.
