Inspired by a stackoverflow answer by William Spinelli

Public Functions

explicit DoubleSlider(QWidget *parent = nullptr)¶: Constructor.

Public Slots

void notifyValueChanged(int value)¶

Process integer values to double values.

Internal values are int, as from QSlider. widget.

Signals

void valueChanged(double value)¶

Signal a changed value.

value user changed value, notify consumer.

class PhaseLabel : public QLabel¶

#include <phaselabel.h>

digraph {
graph [bgcolor="#00000000"]
node [shape=rectangle style=filled fillcolor="#FFFFFF" font=Helvetica padding=2]
edge [color="#1414CE"]
"1" [label="PhaseLabel" tooltip="PhaseLabel" fillcolor="#BFBFBF"]
"2" [label="QLabel" tooltip="QLabel"]
"1" -> "2" [dir=forward tooltip="public-inheritance"]
}

Collaboration diagram for PhaseLabel:

Label class for displaying phase for lissajous curves.

Label constsits of fixed text and valriable numeric part.

Public Functions

explicit PhaseLabel(QString const&, QWidget *parent = nullptr)¶

explicit PhaseLabel(QWidget *parent = nullptr)¶

void setFormat(QString const &name)¶

Set fixed part of label (name) and initialize value.

name defines the fixed part of the label
value defines the intial value for the variable part.

Public Slots

void setNum(const double)¶

Update the variable part of the label.

value is the new value for the variable part.

Private Members

QString format¶
