Linking Components

A Component that wants to link to another components must:

• Derive from Linkable class.
• Implement context menu action ( TODO: add to Component::ContextMenu).
• Implement code to act on linked components.
• Add hidden property "Links".
• Set m_linkable = true; in constructor.

A component that wants to do something when linked must implement one or both:
void setLinkedValue( double v, int i=0 )
void setLinkedString( QString str, int i=0 )

Virtual functions:

component.h:
void setLinkedValue( double v, int i=0 )
void setLinkedString( QString str, int i=0 )
void setLinked( bool l )

linkable.h
void createLinks( QList<Component> )
void compSelected( Component* comp )

Can link to other Components:

• Dial
  Calls:
  setLinkedValue( (int)v, 0 )

• Text Component
  Shows value label from linked components.
  Syntax: $dataN (N = component index).

• Led / Diode
  Calls:
  setLinkedValue( double v, int i )

• Scripted
  Can call:
  component.setLinkedString( string str, int i )
  component.setLinkedValue( double v, int i )
  
  

Can be linked:

• Dialed (Dial, Potentiometer, Variable Resistor, Resistive Sensors):
  Called:
  setLinkedValue( double v, int i=0 )
  i = 0: set Dial value (0-1000)
  else : set value.

• Text Component
  Called:
  setLinkedString( QString str, int i )
  setLinkedValue( double v, int i )
  i = 0: set text.
  else : append text.

• 7 segment BCD
  Called:
  setLinkedValue( double v, int i )
  i = 0: display value.
  else : 1 bit for each segment.

• Clock & Wave Gen
  Called:
  setLinkedValue( double v, int i )
  Set frequency.

• Capacitor
  Called:
  setLinkedValue( double v, int i )
  Set capacitance (0 to 1000 = 0 to 100%).

• Inductor
  Called:
  setLinkedValue( double v, int i )
  Set inductance (0 to 1000 = 0 to 100%).

• Controlled Source
  Called:
  setLinkedValue( double v, int i )
  Set control voltage or current.

• Scripted
  Can be called:
  setLinkedString( string str, int i )
  setLinkedValue( double v, int i )
