Public Slots
void	AdjustWindowLevel (double iMin, double iMax)
	Adjust window/level between the input values. LUT (using the gamma value) will be calculated between those 2 points. Before iMin, LUT = (0, 0, 0) After iMax, LUT = ChannelColor. It modifies the values of the sliders then update the LUT.
void	ApplyChanges ()
	Apply changes (color, min, manx, gamma, opacity TF) to the channel. It modifies informations relative to the given channel in the QGoImageStructure.
void	ChangeColor ()
	Opens a QColorDialog. If chosen color is valid, then: 1- Modify push button color 2- Modify m_TFWidget color 3- Update LUT.
void	ResetLUT ()
	Reset the channel to its original state (color, LUT, opacity)
void	ShowHistogram (bool iShow)
	Show/hide histogram in m_TFWidget.
void	UpdateLUT ()
	Update the LUT based on the min, max and gamma. It updates the m_TFWidget and the visualition.
void	updateOpacityTF ()
void	updateSliders (int iValue)
	When Min and Max sliders change, update the value of the one which sent the signal, if it doesn't overlap with the other one. param[in] iValue new value. Else modify its value back to original.

Signals
void	UpdateImageStructure (QString, std::map< unsigned int, unsigned int >, QColor, int, int, int)
	Modify the image structure when apply clicked.
void	updateVisualization ()
	Modify the visualization when the LUT or opacity changed.

Public Member Functions
void	AddColor (const std::vector< double > &iColor)
	Add color of the channel to the GoTransferFunctionEditorWidget. It modifies m_Color. m_Color is necessary for reset and to initialize the m_TFWidget;.
