Method Detail

setLockValues

void setLockValues(boolean lock)

Locks the control's interface. Values sent to the control will not update the display until the control is unlocked.

Parameters:

lock - boolean

setValue

void setValue(java.lang.String name,
              java.lang.Object val)

Stores a name and a value in the control. GUI controls will usually display the name followed by an equal sign followed by the toString<\code> representation of the object.

Parameters:

name -

val -

setValue

void setValue(java.lang.String name,
              double val)

Stores a name and a double value in the control. GUI controls will usually display the name followed by an equal sign followed by the toString<\code> representation of the double.

Parameters:

name -

val -

setValue

void setValue(java.lang.String name,
              int val)

Stores a name and an integer value in the control. GUI controls will usually display the name followed by an equal sign followed by the toString<\code> representation of the integer.

Parameters:

name -

val -

setValue

void setValue(java.lang.String name,
              boolean val)

Stores a name and a boolean value in the control. GUI controls will usually display the name followed by an equal sign followed by the toString<\code> representation of the integer.

Parameters:

name -

val -

getInt

int getInt(java.lang.String name)

Gets a stored integer value from the control. GUI controls will usually allow the user to edit the value of the parameter.

Parameters:

name -

Returns:

the value of the parameter

getDouble

double getDouble(java.lang.String name)

Gets a stored double value from the control. GUI controls will usually allow the user to edit the value of the parameter.

Parameters:

name -

Returns:

the value of the parameter

getObject

java.lang.Object getObject(java.lang.String name)

Gets the object with the specified property name.

Parameters:

name - the name

Returns:

the object

getString

java.lang.String getString(java.lang.String name)

Gets a stored string from the control. Srings have usually been initialized with the setValue (String name, Object val)<\code> method. GUI controls will usually allow the user to edit the value of the parameter.

Parameters:

name -

Returns:

the value of the parameter

getBoolean

boolean getBoolean(java.lang.String name)
