DialogDescriptor (NetBeans APIs) - NetBeans API Javadoc 4.1.0


org.openide
Class DialogDescriptor

java.lang.Object
  extended byorg.openide.NotifyDescriptor
      extended byorg.openide.DialogDescriptor
All Implemented Interfaces:
HelpCtx.Provider
Direct Known Subclasses:
WizardDescriptor

public class DialogDescriptor
extends NotifyDescriptor
implements HelpCtx.Provider

A description of a standard dialog. It may be built later using DialogDisplayer.createDialog(org.openide.DialogDescriptor) or shown with DialogDisplayer.notify(org.openide.NotifyDescriptor). It extends NotifyDescriptor's capabilities by allowing specification of the modal/nonmodal state of the dialog, button behavior and alignment, help, and a listener on button presses. Anyone who wants to display some kind of dialog with standard behavior should use this class to describe it and use createDialog(d) to build it. When the dialog is closed you may use NotifyDescriptor.getValue() to determine which button closed it.

The property message (inherited from NotifyDescriptor) is primarily used here to specify the inner GUI component of the dialog, in contrast to NotifyDescriptor which generally uses a String message.

If you want to set one of the custom Options to be the default Option, it is possible to call DialogDescriptor.setValue(the button you want to have default...)

DialogDescriptor

public DialogDescriptor(Object innerPane,
                        String title)
Create modal dialog descriptor with given title and inner part, with OK/Cancel buttons with default alignment, no help available. All buttons will close the dialog and the getValue () will provide the pressed option.

Parameters:
innerPane - inner component of the dialog, or String message
title - title of the dialog

DialogDescriptor

public DialogDescriptor(Object innerPane,
                        String title,
                        boolean isModal,
                        ActionListener bl)
Create dialog descriptor with given title, inner part and modal status, with OK/Cancel buttons displayed with default alignment, no help available. If bl is not null, then it will receive notifications when the user presses the buttons. (If no listener is specified, it's still possible to retrieve the user-selected button using NotifyDescriptor.getValue().)

Parameters:
innerPane - inner component of the dialog, or String message
title - title of the dialog
isModal - modal status
bl - listener for user's button presses

DialogDescriptor

public DialogDescriptor(Object innerPane,
                        String title,
                        boolean isModal,
                        int optionType,
                        Object initialValue,
                        ActionListener bl)
Create dialog descriptor with given title, inner part, modal status, option type and default option. Options have default alignment, no help available. If the action listener is null, all option buttons will close the dialog and the getValue () will provide the pressed option.

Parameters:
innerPane - inner component of the dialog, or String message
title - title of the dialog
isModal - modal status
optionType - one of the standard options (OK_CANCEL_OPTION, ...)
initialValue - default option (default button)
bl - listener for the user's button presses or null for default close action on all options

DialogDescriptor

public DialogDescriptor(Object innerPane,
                        String title,
                        boolean modal,
                        Object[] options,

                        HelpCtx helpCtx,
                        ActionListener bl)
Create dialog descriptor; possibility of specifying custom array of options and their alignment. If the action listener is null, all option buttons will close the dialog and the getValue () will provide the pressed option. When a custom option set is provided, if any of the standard options (OK_OPTION, CLOSE_OPTION or CANCEL_OPTION) are used, the dialog will close when a button for a standard option is pressed; otherwise for custom options, closing the dialog is left to the ActionListener or setClosingOptions.

Parameters:
innerPane - inner component of the dialog, or String message
title - title of the dialog
modal - modal status
options - array of custom options (null means no options at all); may include strings (for button labels; such buttons then do nothing by default) or components (such as buttons, in which case you are responsible for listening to the buttons yourself)
initialValue - default option from custom option array
optionsAlign - specifies where to place options in the dialog
helpCtx - help context specifying help page
bl - listener for the user's button presses or null for default close action on all options (unless you specified the options yourself)

When a custom option set is provided, if any of the standard options (OK_OPTION, CLOSE_OPTION or CANCEL_OPTION) are used, the dialog will close when a button for a standard option is pressed; otherwise for custom options, closing the dialog is left to the ActionListener or setClosingOptions.

Parameters:
innerPane - inner component of the dialog, or String message
title - title of the dialog

Method Detail

getOptionsAlign

public int getOptionsAlign()
Get current option alignment.

Returns:
current option alignment
See Also:
setOptionsAlign(int)

setOptionsAlign

public void setOptionsAlign(int optionsAlign)
Set new option alignment. See aligment constants for possible values. Fires property change event if successful.

Parameters:
optionsAlign - new options alignment
Throws:
IllegalArgumentException - when unknown alignment is given
See Also:
DEFAULT_ALIGN

isModal

public boolean isModal()
Get modal status.

Returns:
modal status
See Also:
setModal(boolean)

setModal

public void setModal(boolean modal)
Set new modal status. Fires property change event if successful.

Parameters:
modal - new modal status
See Also:
isModal()

isLeaf

public boolean isLeaf()
Get leaf status. If is leaf then cannot be the owner to other one dialog.

Returns:
leaf status
Since:
5.5
See Also:
setLeaf(boolean)

setLeaf

public void setLeaf(boolean leaf)
Set new leaf status. Fires property change event if successful.

Parameters:
leaf - new leaf status
Since:
5.5
See Also:
isLeaf()

setClosingOptions

public void setClosingOptions(Object[] arr)
Setter for list of options that close the dialog. Special values are:
  • null - all options will close the dialog
  • empty array - no option will close the dialog

Parameters:
arr - array of options that should close the dialog when pressed if null then all options close the dialog

getClosingOptions

public Object[] getClosingOptions()
Getter for list of closing options.

Returns:
array of options or null

getHelpCtx

public HelpCtx getHelpCtx()
Get current help context asociated with this dialog descriptor.

Specified by:
getHelpCtx in interface HelpCtx.Provider
Returns:
current help context
See Also:
setHelpCtx(org.openide.util.HelpCtx)

setHelpCtx

public void setHelpCtx(HelpCtx helpCtx)
Set new help context for this dialog descriptor. Fires property change event if successful.

The implementation should automatically display a help button among the secondary options, without your needing to specify it, if the help context on the descriptor is neither null nor HelpCtx.DEFAULT_HELP. If the descriptor is null, this feature will be disabled (you can still add your own help button manually if you wish, of course). If DEFAULT_HELP (the default), normally the button will also be disabled, however if the inner pane is a component and this component has an associated help ID, that will be used automatically. So most users should never need to manually add a help button: call this method with the correct context, or associate an ID with the displayed component. Note that to set it to null you must explicitly call this method; passing null in the constructor actually sets it to DEFAULT_HELP.

Parameters:
helpCtx - new help context, can be null (no help)
See Also:
getHelpCtx()

getButtonListener

public ActionListener getButtonListener()
Get button listener which listens for the user's button presses.

Returns:
current button listener instance or null
See Also:
setButtonListener(java.awt.event.ActionListener)

setButtonListener

public void setButtonListener(ActionListener l)
Set new button listener instance for this dialog descriptor. Fires property change event if successful.

Parameters:
l - new button listener. It may be null, in which case listening is cancelled.

getButtonListener()
