public class ColumnDefEditor

extends Panel

implements VisualObjectPropertyEditor, CustomOverride, HelpProvider

symantec.itools.db.beans.binding.ColumnDefEditor()

Default constructor

addCustomOverrideListener(CustomOverrideListener)

addPropertyChangeListener(PropertyChangeListener)

Register a listener for the PropertyChange event.

getAsText()

getCustomEditor()

A PropertyEditor may choose to make available a full custom Component that edits its property value.

getHelpID()

getJavaInitializationString()

This method is intended for use when generating Java code to set the value of the property.

getObject()

getTags()

If the property value must be one of a set of known tagged values, then this method should return an array of the tags.

getValue()

getVisualObject()

invokeHelp()

isPaintable()

paintValue(Graphics, Rectangle)

Paint a representation of the value into a given area of screen real estate.

removeCustomOverrideListener(CustomOverrideListener)

removePropertyChangeListener(PropertyChangeListener)

Remove a listener for the PropertyChange event.

setAsText(String)

Set the property value by parsing a given String.

setObject(Object)

setValue(Object)

Set (or change) the object that is to be edited.

setVisualObject(VisualObject)

supportsCustomEditor()

public ColumnDefEditor()

Default constructor

public void addCustomOverrideListener(CustomOverrideListener listener)

public synchronized void addPropertyChangeListener(PropertyChangeListener listener)

Register a listener for the PropertyChange event. When a PropertyEditor changes its value it should fire a PropertyChange event on all registered PropertyChangeListeners, specifying the null value for the property name and itself as the source.

Parameters:

listener - An object to be invoked when a PropertyChange event is fired.

public java.lang.String getAsText()

Returns:

The property value as a human editable string.

Returns null if the value can't be expressed as an editable string.

If a non-null value is returned, then the PropertyEditor should be prepared to parse that string back in setAsText().

public java.awt.Component getCustomEditor()

A PropertyEditor may choose to make available a full custom Component that edits its property value. It is the responsibility of the PropertyEditor to hook itself up to its editor Component itself and to report property value changes by firing a PropertyChange event.

The higher-level code that calls getCustomEditor may either embed the Component in some larger property sheet, or it may put it in its own individual dialog, or ...

Returns:

A java.awt.Component that will allow a human to directly edit the current property value. May be null if this is not supported.

public int getHelpID()

public java.lang.String getJavaInitializationString()

This method is intended for use when generating Java code to set the value of the property. It should return a fragment of Java code that can be used to initialize a variable with the current property value.

Example results are "2", "new Color(127,127,34)", "Color.orange", etc.

Returns:

A fragment of Java code representing an initializer for the current value.

public java.lang.Object getObject()

public java.lang.String[] getTags()

If the property value must be one of a set of known tagged values, then this method should return an array of the tags. This can be used to represent (for example) enum values. If a PropertyEditor supports tags, then it should support the use of setAsText with a tag value as a way of setting the value and the use of getAsText to identify the current value.

Returns:

The tag values for this property. May be null if this property cannot be represented as a tagged value.

public java.lang.Object getValue()

Returns:

The value of the property. Builtin types such as "int" will be wrapped as the corresponding object type such as "java.lang.Integer".

public com.symantec.itools.vcafe.openapi.VisualObject getVisualObject()

public void invokeHelp()

public boolean isPaintable()

Returns:

True if the class will honor the paintValue method.

public void paintValue(Graphics gfx,
                       Rectangle box)

Paint a representation of the value into a given area of screen real estate. Note that the propertyEditor is responsible for doing its own clipping so that it fits into the given rectangle.

If the PropertyEditor doesn't honor paint requests (see isPaintable) this method should be a silent noop.

The given Graphics object will have the default font, color, etc of the parent container. The PropertyEditor may change graphics attributes such as font and color and doesn't need to restore the old values.

Parameters:

gfx - Graphics object to paint into.

box - Rectangle within graphics object into which we should paint.

public void removeCustomOverrideListener(CustomOverrideListener listener)

public synchronized void removePropertyChangeListener(PropertyChangeListener listener)

Remove a listener for the PropertyChange event.

Parameters:

listener - The PropertyChange listener to be removed.

public void setAsText(String text) throws IllegalArgumentException

Set the property value by parsing a given String. May raise java.lang.IllegalArgumentException if either the String is badly formatted or if this kind of property can't be expressed as text.

Parameters:

text - The string to be parsed.

public void setObject(Object object)

public void setValue(Object val)

Set (or change) the object that is to be edited. Builtin types such as "int" must be wrapped as the corresponding object type such as "java.lang.Integer".

Parameters:

value - The new target object to be edited. Note that this object should not be modified by the PropertyEditor, rather the PropertyEditor should create a new object to hold any modified value.

public void setVisualObject(VisualObject visualObject)

public boolean supportsCustomEditor()

Returns:

True if the propertyEditor can provide a custom editor.
