Method Detail

createVisual

protected java.awt.Component createVisual(java.lang.Object _visual)

Description copied from class: ControlSwingElement

Creates the visual component of this ControlElement, the one you can configure graphically. If an object of an appropriate class is provided, it is used as the visual.

Specified by:

createVisual in class ControlSwingElement

Parameters:

_visual - The javax.swing.JComponent to be wrapped

reset

public void reset()

Description copied from class: ControlElement

resets the element

Overrides:

reset in class ControlElement

setInternalValue

protected void setInternalValue(double _value)

getPropertyList

public java.util.ArrayList<java.lang.String> getPropertyList()

Description copied from class: ControlSwingElement

Returns the list of all properties that can be set for this ControlElement. Subclasses that add properties should extend this table. Order is crucial here: Both for the presentation in an editor (f.i. ViewElement) and for the setValue() method.

Overrides:

getPropertyList in class ControlSwingElement

getPropertyInfo

public java.lang.String getPropertyInfo(java.lang.String _property)

Description copied from class: ControlSwingElement

Returns information about a given property. Subclasses that add properties should extend this table.

The first keyword is ALWAYS the type.

The keyword CONSTANT applies to properties that can not be changed using the setValue() methods

The keyword BASIC is used by Ejs to group properties to the left hand side of the property editor

The keyword HIDDEN is used by Ejs so that it does not display an entry in the editor field

Overrides:

getPropertyInfo in class ControlSwingElement

setValue

public void setValue(int _index,
                     Value _value)

Description copied from class: ControlSwingElement

Sets the value of the registered variables. Subclasses with internal values should extend this

Overrides:

setValue in class ControlSwingElement

Parameters:

_index - A keyword index that distinguishes among variables

_value - The object holding the value for the variable.

setDefaultValue

public void setDefaultValue(int _index)

Overrides:

setDefaultValue in class ControlSwingElement

getValue

public Value getValue(int _index)

Description copied from class: ControlSwingElement

Gets the value of any internal variable. Subclasses with internal values should extend this

Overrides:

getValue in class ControlSwingElement

Parameters:

_index - A keyword index that distinguishes among variables

Returns:

Value _value The object holding the value for the variable.

setColor

protected void setColor(java.awt.Color aColor)
