All Implemented Interfaces:
InstallerEventListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible

public abstract class CustomScreen
extends javax.swing.JPanel
implements InstallerEventListener

All custom screens must be derived from this class. You have to implement all abstract methods and provide a public constructor with no arguments. Instances of derived custom screens have to be registered in the "installer GUI" step of the install4j GUI. Every custom screen is an InstallerEventListener and is automatically registered with the InstallerWizardContext to receive application events. If you want to react to these events you have to override the installerEvent method.

Note: This class is only relevant for install4j Enterprise Edition.

Constructor Detail

CustomScreen

public CustomScreen()
Method Detail

getInstallerContext

public InstallerWizardContext getInstallerContext()
Returns the InstallerWizardContext that the framework has associated with this custom screen in setInstallerContext.

Returns:
the context.

setInstallerContext

public void setInstallerContext(InstallerWizardContext context)
This method is called by the framework to set the InstallerWizardContext. This is the context that is returned from getInstallerContext. If you have to register an InstallerEventListener on the context (note that the screen itself is already registered), you can override this method. Do not forget to call the super implementation in that case.

Parameters:
context - the context.

getTitle

public abstract java.lang.String getTitle()
Returns the title of this custom screen which is displayed at the top of the installer wizard.

Returns:
the title.

getSubTitle

public abstract java.lang.String getSubTitle()
Returns the subtitle of this custom screen which is displayed at the top of the installer wizard just below the title of the screen.

Returns:
the title.

isFillVertical

public abstract boolean isFillVertical()
Returns whether this screen wants to grow in the vertical direction. If not, the screen will be aligned at the top of the available space and be sized at its preferred vertical size. If, for example, you have a list in your layout that should use as much vertical space as possible, you should return true here. In that case you would also want to return true in isFillHorizontal. If all your components are fixed-size components, return false.

Returns:
true or false.

isFillHorizontal

public abstract boolean isFillHorizontal()
Returns whether this screen wants to grow in the horizontal direction. If not, the screen will be aligned at the left of the available space and be sized at its preferred horizontal size. If, for example, you have text fields in your layout that should use as much horizontal space as possible, you should return true here. If all your components are fixed-size components, return false.

Returns:
true or false.

isNextVisible

public boolean isNextVisible()
Returns whether the "Next" button is visible or not for this screen. If you just want to disable the button initially, please override activate and invoke setNextButtonEnabled in the InstallerWizardContext.

Returns:
true or false. Default is true.

isPreviousVisible

public boolean isPreviousVisible()
Returns whether the "Back" button is visible or not for this screen. If you just want to disable the button initially, please override activate and invoke setPreviousButtonEnabled in the InstallerWizardContext.

Returns:
true or false. Default is true.

isCancelVisible

public boolean isCancelVisible()
Returns whether the "Cancel" button is visible or not for this screen. If you just want to disable the button initially, please override activate and invoke setCancelButtonEnabled in the InstallerWizardContext.

Returns:
true or false. Default is true.

isFinishScreen

public boolean isFinishScreen()
Returns whether this is a screen that finished the wizard. The "Next" button will have the caption "Finish" in this case and will close the wizard when clicked.

Returns:
true or false. Default is false.

showOnNext

public boolean showOnNext()
Returns whether this screen should be shown when the user traverses screens in the forward direction. You can override this method and showOnPrevious to conditionally disable the screen.

Returns:
true or false. Default is true.

showOnPrevious

public boolean showOnPrevious()
Returns whether this screen should be shown when the user traverses screens in the backward direction. You can override this method and showOnNext to conditionally disable the screen.

Returns:
true or false. Default is true.

activated

public void activated()
Called by the framework when the screen is activated. Override this method to do any special initialization.


deactivated

public void deactivated()
Called by the framework when the screen is deactivated. Override this method to do any special cleanup.


installerEvent

public void installerEvent(InstallerEvent event)
Description copied from interface: InstallerEventListener
Called when an application event is fired.

Specified by:
installerEvent in interface InstallerEventListener
Parameters:
event - the event

next

public boolean next()
Called when the user clicks the "Next" button for this screen. You can veto the change to the next screen if you return false.

Returns:
whether the screen change is accepted or not. Default is true.

previous

public boolean previous()
Called when the user clicks the "Back" button for this screen. You can veto the change to the previous screen if you return false.

Returns:
whether the screen change is accepted or not. Default is true.

cancel

public boolean cancel()
Called when the user clicks the "Cancel" button for this screen. You can veto the cancel action if you return false.

Returns:
whether the cancellation is accepted or not. Default is true.

getFrame

public javax.swing.JFrame getFrame()
Returns the frame of the installer wizard.

Returns:
the frame.
