Inheritance diagram of QLed
class QLed(parent=None, designMode=False)[source]

A Led

Import from taurus.qt.qtgui.display as:

from taurus.qt.qtgui.display import QLed
DefaultBlinkingInterval = 0
DefaultLedColor = 'green'
DefaultLedInverted = False
DefaultLedPattern = 'leds_images256:led_{color}_{status}.png'
DefaultLedStatus = True
blinkingInterval

This property holds the blinking interval in millisecs. 0 means no blinking

Access functions:

getBlinkingInterval()[source]

returns the blinking interval

Returns

blinking interval or 0 if blinking is not enabled.

Return type

int

getLedColor()[source]

Returns the led color :return: led color :rtype: str

getLedInverted()[source]

Returns if the led is inverted. :return: inverted mode :rtype: bool

getLedPatternName()[source]

Returns the current led pattern name :return: led pattern name :rtype: str

getLedStatus()[source]

Returns the led status :return: led status :rtype: bool

classmethod getQtDesignerPluginInfo()[source]
isLedColorValid(name)[source]

Determines if the given color name is valid.

Parameters

color (str) – the color

Returns

True is the given color name is valid or False otherwise

Return type

bool

ledColor

This property holds the led color

Access functions:

ledInverted

Access functions:

ledPattern

This property holds the led pattern name

Access functions:

ledStatus

This property holds the led status: False means OFF, True means ON

Access functions:

minimumSizeHint()[source]

Overwrite the default minimum size hint (0,0) to be (16,16) :return: the minimum size hint 16,16 :rtype: PyQt5.Qt.QSize

resetBlinkingInterval()[source]

resets the blinking interval

resetLedColor()[source]

Resets the led color

resetLedInverted()[source]

Resets the led inverted mode

resetLedPatternName()[source]

Resets the led pattern to leds/images256/led_{color}_{status}.png

resetLedStatus()[source]

Resets the led status

setBlinkingInterval(interval)[source]

sets the blinking interval (the time between status switching). Set to a nonpositive number for disabling blinking

Parameters

interval (int) – the blinking interval in millisecs. Set to 0 for disabling blinking

setLedColor(color)[source]

Sets the led color

Parameters

status (str) – the new color

setLedInverted(inverted)[source]

Sets the led inverted mode

Parameters

status (bool) – the new inverted mode

setLedPatternName(name)[source]

Sets the led pattern name. Should be a string containing a path to valid images. The string can contain the keywords:

  1. {status} - transformed to ‘on’ of ‘off’ according to the status

  2. {color} - transformed to the current led color

Example: :leds/images256/led_{color}_{status}.png will be transformed to :leds/images256/led_red_on.png when the led status is True and the led color is red.

Parameters

name (str) – new pattern

setLedStatus(status)[source]

Sets the led status

Parameters

status (bool) – the new status

sizeHint(self) QSize[source]
toLedName(status=None, color=None, inverted=None)[source]

Gives the led name for the given status and color. If status or color are not given, the current led status or color are used.

Parameters
  • status (bool) – the status

  • color (str) – the color

Returns

string containing the led name

Return type

str

toggleLedStatus()[source]

toggles the current status of the led
