Constructor Detail

NotifyDescriptor

public NotifyDescriptor(Object message,
                        String title,
                        int optionType,
                        int messageType,
                        Object[] options,
                        Object initialValue)
Creates a new notify descriptor with specified information to report. If optionType is YES_NO_OPTION or YES_NO_CANCEL_OPTION and the options parameter is null, then the options are supplied by the look and feel. The messageType parameter is primarily used to supply a default icon from the look and feel.

Parameters:
message - the object to display
title - the title string for the dialog
optionType - indicates which options are available
messageType - indicates what type of message should be displayed
options - an array of objects indicating the possible choices
initialValue - the object that represents the default value
See Also:
getMessage(), getMessageType(), getOptions(), getOptionType(), getValue()
Method Detail

initialize

protected void initialize()
Method that is called before a value is returned from any of getter methods in this object. Allows subclasses to do some additional initialization actions.


isValid

public final boolean isValid()
Return true if OK button is valid (enabled), otherwise return false.

Returns:
validity status of OK button.
See Also:
setValid(boolean)

setValid

public final void setValid(boolean newValid)
Set validity of OK button.

Parameters:
newValid - validity status of OK button
See Also:
isValid()

setMessage

public void setMessage(Object newMessage)
Define a descriptive message to be reported. In the most common usage, the message is just a String. However, the type of this parameter is actually Object. Its interpretation depends on its type:
Object[]
A recursively interpreted series of messages.
Component
The Component is displayed in the dialog.
Icon
The Icon is wrapped in a JLabel and displayed in the dialog.
anything else
The string representation of the object.

Parameters:
newMessage - the Object to report

getMessage()

getMessage

public Object getMessage()
Get the message object.

Returns:
the Object that is to be reported
See Also:
setMessage(java.lang.Object)

setMessageType

public void setMessageType(int newType)
Define the style of the message. The look and feel manager may lay out the dialog differently depending on this value, and will often provide a default icon. The possible values are:

Parameters:
newType - the kind of message
See Also:
getMessageType()

getMessageType

public int getMessageType()
Get the message type.

Returns:
the message type
See Also:
setMessageType(int)

setOptionType

public void setOptionType(int newType)

Parameters:
newType - the options the look and feel is to display
See Also:
getOptionType(), setOptions(java.lang.Object[])

getOptionType

public int getOptionType()

setOptions

public void setOptions(Object[] newOptions)

The component is added to the button row directly.
Icon
A JButton is created with this icon as its label.
anything else
The Object is converted to a string and the result is used to label a JButton.

Parameters:
newOptions - an array of user-selectable options
