Detailed Description

An adapted CTrackBarCtrl control around a ScopeNumber<double>.

Implements a slider control, either with incremental or continuous value changes.
ScopeNumber = slider * scalefactor + offset viceversa slider = (ScopeNumber - offset) / scalefactor
If not incrementing we have only 10 ticks (although we slider positions from 0...100)

Warning: Needs message reflection in containing (dialog) window via REFLECT_NOTIFICATIONS()

Constructor & Destructor Documentation

scope::gui::CScopeSliderCtrl::CScopeSliderCtrl	(	ScopeNumber< double > *	_scopenum,
		const double &	_increment = `0`,
		const bool &	_connectback = `false`,
		const bool &	_connectcontrolstate = `false`
	)

()

Gets a pointer to the ScopeNumber<double> and connects if desired

Parameters

[in]	_scopenum	ScopeNumber to which the slider connects
[in]	_increment	discrete increment of underlying ScopeNumber or 0 for (nearly) continuous changing of the ScopeNumber (slider range is 0-100 and converted accordingly)
[in]	_connectback	change slider value when ScopeNumber is changed
[in]	_connectcontrolstate	change slider enabled/disabled state when read/write state is set at the ScopeNumber

bool scope::gui::CScopeSliderCtrl::created

protected

true if window created

Definition at line 18 of file ScopeSliderCtrl.h.

ScopeNumber<double>* const scope::gui::CScopeSliderCtrl::scopenum

protected

Pointer to the underlying ScopeNumber.

Definition at line 21 of file ScopeSliderCtrl.h.

boost::signals2::connection scope::gui::CScopeSliderCtrl::stateconnection

protected

The connection object for the control state (connection to the scopenum rw state change)

Definition at line 24 of file ScopeSliderCtrl.h.

boost::signals2::connection scope::gui::CScopeSliderCtrl::valueconnection

protected

The connection object for the control state (connection to the scopenum value change)

Definition at line 27 of file ScopeSliderCtrl.h.

const double scope::gui::CScopeSliderCtrl::increment

protected

if != 0, then scopenum can only be changed by multiples of increment and the slider should display tick marks accordingly

Definition at line 30 of file ScopeSliderCtrl.h.

const double scope::gui::CScopeSliderCtrl::scalefactor

protected

scalefactor is increment or range/100 (if not incrementing)

Definition at line 33 of file ScopeSliderCtrl.h.

const double scope::gui::CScopeSliderCtrl::offset

protected

is ScopeNumber lower limit

Definition at line 36 of file ScopeSliderCtrl.h.

const int32_t scope::gui::CScopeSliderCtrl::rangehigh

protected

the upper end of the slider range (100 if not incrementing, otherwise range/increment)

Definition at line 39 of file ScopeSliderCtrl.h.

const int32_t scope::gui::CScopeSliderCtrl::rangelow

protected

lower end of the slider range, usually 0

Definition at line 42 of file ScopeSliderCtrl.h.

bool scope::gui::CScopeSliderCtrl::shiftstate

protected

stores state of shift key
