Detailed Description

Base class for the HScale and VScale classes.

This class operates by using the "<<" operator to load in the VScaleFuncData and HScaleFuncData classes, like so :

Scales scales;

scales<<HScaleFuncData(0.,100.,1.,scaleTouch,NULL)<<VScaleFuncData(0.,100.,1.,scaleTouch,NULL);

The scales can be set by locating the desired scale widget to set and then using the "=" operator :

scales.grab(1);
scales=50.9;
scales.grab(2);
scales=50.9;

Member Function Documentation

◆ drawValue()

Scales& Scales::drawValue ( )

inline

Draw the value above the scale widget.

Returns: A reference to this scale class.

Definition at line 321 of file Scales.H.

◆ findIndex()

int Scales::findIndex ( GtkWidget * widget )

inline

Find the GTK widget index (from 1) in the list of scales

Parameters

widget The widget to look for

Returns: 0 if it isn't on the list, the index (from 1) otherwise

Definition at line 356 of file Scales.H.

◆ getLower()

double Scales::getLower ( void )

inline

Get the lower range value.

Returns: The current lower value.

Definition at line 275 of file Scales.H.

◆ getStep()

double Scales::getStep ( void )

inline

Get the stepping value of the scale widget.

Returns: the stepping value of the scale. If there are no scales, then return NaN

Definition at line 214 of file Scales.H.

◆ getUpper()

double Scales::getUpper ( void )

inline

Set the upper range value.

Returns: The current upper value.

Definition at line 289 of file Scales.H.

◆ getVal() [1/2]

static double Scales::getVal ( GtkRange * wid )

inlinestatic

Get the current value of the provided scale widget.

Parameters

wid	The widget to get the position from

Returns: the value the scale is set to.

Examples:: ScaleTest.C.

Definition at line 198 of file Scales.H.

Here is the caller graph for this function:

◆ getVal() [2/2]

double Scales::getVal ( void )

inline

Get the current value of the scale widget.

Returns: the value the scale is set to. If there are no scales, then return NaN

Definition at line 205 of file Scales.H.

◆ invert()

void Scales::invert ( bool isInverted )

inline

Turn the scale upside down (Vertical scales) or flip left/right (Horizontal scales)

Parameters

isInverted True to invert, False to return to normal transposition

Definition at line 405 of file Scales.H.

◆ operator<<() [1/2]

Scales& Scales::operator<< ( HScaleFuncData sf )

inline

Create a horizontal scale widget

Parameters

sf	The HScaleFuncData which defines the horizontal scale

Returns: A reference to this scale class.

Definition at line 330 of file Scales.H.

Here is the call graph for this function:

◆ operator<<() [2/2]

Scales& Scales::operator<< ( VScaleFuncData sf )

inline

Create a vertical scale widget

Parameters

sf	The VScaleFuncData which defines the vertical scale

Returns: A reference to this scale class.

Definition at line 343 of file Scales.H.

Here is the call graph for this function:

◆ operator=() [1/2]

Scales& Scales::operator= ( double pos )

inline

Set the scale to a particular value.

Parameters

pos	The value to set the scale to.

Returns: A reference to this scale class.

Definition at line 304 of file Scales.H.

◆ operator=() [2/2]

Scales& Scales::operator= ( int pos )

inline

Set the scale to a particular value.

Parameters

pos	The value to set the scale to.

Returns: A reference to this scale class.

Definition at line 314 of file Scales.H.

◆ quantise()

void Scales::quantise ( bool isQuantised )

inline

Quantise the scale to the step size. If the user slides it, then it is quantised to the closest step size increment.

Definition at line 394 of file Scales.H.

◆ quantiseVal()

static void Scales::quantiseVal	(	void *	wid,
		void *	data
	)

inlinestaticprivate

Perform the quantisation of the widget

Parameters

wid	The widget which caused this callback.
data	The user data associated with that button press.

Definition at line 178 of file Scales.H.

Here is the call graph for this function:

◆ setDigits()

void Scales::setDigits ( double step )

inlineprivate

Auto-set the number of decimal points to display in the slider

Parameters

step	The slider stepping factor between movements.

Definition at line 164 of file Scales.H.

◆ setLower()

void Scales::setLower ( double lower )

inline

Set the lower range value.

Parameters

lower The new lower value.

Definition at line 244 of file Scales.H.

◆ setStep()

void Scales::setStep ( double step )

inline
