Parameters

parent the QObject which will be the parent for the QuWriter.

◆ attach()

void QuWriter::attach	(	QObject *	executor,
		const char *	signal,
		const char *	setPointSlot = `NULL`,
		Qt::ConnectionType	connType = `Qt::AutoConnection`
	)

virtual

Signal signal of the executor is connected to the execute method of this class.

The available slots are listed below.

Parameters

executor	the QObject to which we connect to receive an execution signal
signal	the signal name, declared with the SIGNAL macro which we are listening for
setPointSlot	provide a custom slot to initialize the set point value inside the auto configuration method.
connType	the Qt connection type.

Example: QuWriter *dualWriter = new QuWriter(this);

dualWriter->attach(ui.writeDial, SIGNAL(sliderMoved(int)), SLOT(setValue(int)));

dualWriter->setTargets("test/device/1/double_scalar");

QuWriter
A class that can be used to write values from (almost) any kind of widget or object.
Definition: quwriter.h:27

QuWriter::attach
virtual void attach(QObject *executor, const char *signal, const char *setPointSlot=NULL, Qt::ConnectionType connType=Qt::AutoConnection)
Signal signal of the executor is connected to the execute method of this class.
Definition: quwriter.cpp:60

Every time the slider is moved, it emits sliderMoved(int) signal. The QuWriter internally connects sliderMoved(int) signal to the execute(int) slot, recognizing the signal input parameter type. In the example above, when auto configuration of "test/device/1/double_scalar" is available, the current set point of double_scalar is set on the widget via the setValue(int) SLOT.

Reimplemented from Qumbiaizer.

◆ execute [1/11]

void QuWriter::execute ( )

empty argument version. Takes the input arguments to write from the targets

\bref the execute method tailored for a void input value

See also: void execute(int)

targets are analysed and an input argument is extracted, if possible. Otherwise the writing is performed with an empty value. For example, if targets are

p/power_supply/super_ps/Current(&doubleSpinboxCurrent)

the value of the current is taken by the spinbox with name doubleSpinboxCurrent

◆ execute [9/11]

void QuWriter::execute ( int i )

the execute method tailored for integer values

The execute method can be reimplemented in subclasses to specialize its behaviour. By default, the signal provided inside attach method is connected to this slot, when the signal has an integer input type. For instance, when the value of a QSpinBox changes, this slot can be invoked.
