Detailed Description

This class represents a popup widget containing three separate spin boxes, each corresponding to one of the RGB (Red, Green, Blue) color channels. It allows fine-grained control over the adjustment of individual channel number.

The spin boxes can be used to independently select which channel of a spectral image should be used to construct an RGB image.

Public Attributes Documentation

variable m_spinBox1

Spin box for managing one of the RGB channel values. 

QSpinBox* QRgbChannelSpinBoxesPopup::m_spinBox1;

Represents a spin box widget used to manage the value of one of the RGB channels (red, green, or blue). This spin box allows users to input integer values within a defined range. It is part of the popup widget and interacts with the corresponding signals and slots for handling RGB value changes.

variable m_spinBox2

Spin box for managing one of the RGB channel values. 

QSpinBox* QRgbChannelSpinBoxesPopup::m_spinBox2;

Represents a spin box widget used to manage the value of one of the RGB channels (red, green, or blue). This spin box allows users to input integer values within a defined range. It is part of the popup widget and interacts with the corresponding signals and slots for handling RGB value changes.

variable m_spinBox3

Spin box for managing one of the RGB channel values. 

QSpinBox* QRgbChannelSpinBoxesPopup::m_spinBox3;

Represents a spin box widget used to manage the value of one of the RGB channels (red, green, or blue). This spin box allows users to input integer values within a defined range. It is part of the popup widget and interacts with the corresponding signals and slots for handling RGB value changes.

Public Slots Documentation

slot UpdateRgb

Updates the RGB values of the spin boxes and emits a value change signal. 

void QRgbChannelSpinBoxesPopup::UpdateRgb;

This function updates the values of the internal spin boxes representing the red, green, and blue channels. It also emits a signal with the updated RGB values as a vector, notifying other connected components of the change.

Parameters:

  • red The new value for the red channel.
  • green The new value for the green channel.
  • blue The new value for the blue channel.

Public Signals Documentation

signal ValueChanged

Signal emitted when the RGB values change. 

void QRgbChannelSpinBoxesPopup::ValueChanged;

This signal is emitted whenever the values of the RGB spin boxes are updated either through user input or programmatically. The updated RGB values are passed as a vector of integers in the order: red, green, blue.

Parameters:

  • rgb A vector containing the updated RGB values in the order: red, green, blue.

Public Functions Documentation

function QRgbChannelSpinBoxesPopup

Popup widget for managing RGB channel values using spin boxes. 

explicit QRgbChannelSpinBoxesPopup::QRgbChannelSpinBoxesPopup (
    QWidget * parent=nullptr
)

Parameters:

  • parent The parent widget for this popup widget. Defaults to nullptr.

function getRgb

Retrieves the current RGB values from the spin boxes. 

std::vector< int > QRgbChannelSpinBoxesPopup::getRgb () const

This method returns the current values of the red, green, and blue channels as integers stored in a vector. These values represent the state of the RGB spin boxes in the popup widget.

Returns:

A vector of integers containing the RGB values in the order: red, green, blue.
