Class TLcyPrintPreviewFactory

java.lang.Object

com.luciad.lucy.addons.print.ALcyPrintPreviewFactory<TLcyPrintContext>

com.luciad.lucy.addons.print.TLcyPrintPreviewFactory

public class TLcyPrintPreviewFactory
extends ALcyPrintPreviewFactory<TLcyPrintContext>

Factory for the creation of the content of the print preview dialog. This factory was designed so that it is easy to modify small parts of the creation process. This can be done by subclassing this class and overriding certain methods.

The main create function createPrintPreview(com.luciad.lucy.addons.print.TLcyPrintContext, com.luciad.gui.ILcdAction) first creates all actions, all components and then all panels using the functions createAction(int, com.luciad.lucy.addons.print.TLcyPrintContext, com.luciad.gui.ILcdAction), createComponent and createPanel. Then it calls createPrintPreviewContent(), which will create the content of the print preview using the created panels by calling getPanel. And finally it will create the actual content of the print preview dialog.

Note however that ID's are used. This is because there are different types of, for example, panels that can be created: the option panel, the printing area settings panel,... All possible ID's that can be passed to the createPanel method all end with the same suffix "PANEL". The same thing goes for "COMPONENT" (createComponent, getComponent) and "ACTION" (createAction, getAction.

As an example, imagine you want to change the behaviour of the options panel. Browsing this class learns there is a OPTIONS_PANEL constant. Because it ends with "PANEL", this constant can only be passed to the createPanel method. Therefore we can override the method createPanel, check if the ID is OPTIONS_PANEL and return a custom panel. Or use super.createComponent and change some settings before returning it. If you want to remove the component completely, you can simply return null.

The method createPrintPreview should not be overridden without using the super function. Changing the layout of the content of the print preview dialog can be done by overriding createPrintPreviewContent. The internal elements are already created and should be retrieved by calling getComponent.

Note that this class requires a default constructor to be able to configure it in the configuration file of the print add-on.

Constructor Details

TLcyPrintPreviewFactory

public TLcyPrintPreviewFactory()

Default constructor. Creates a new TLcyPrintPreviewFactory. Note that you will have to set an ILcyLucyEnv before this instance can be used.

Note that this class requires a default constructor to be able to configure it in the configuration file of the print add-on.

TLcyPrintPreviewFactory

public TLcyPrintPreviewFactory(ILcyLucyEnv aLucyEnv)

Creates a new TLcyPrintPreviewFactory.

Parameters:

aLucyEnv - The lucy environment, contextual information.

Method Details

getLucyEnv

public ILcyLucyEnv getLucyEnv()

Description copied from class: ALcyPrintPreviewFactory

Returns the associated lucy environment.

Specified by:

getLucyEnv in class ALcyPrintPreviewFactory<TLcyPrintContext>

Returns:

the associated lucy environment.

See Also:

• ALcyPrintPreviewFactory.setLucyEnv(com.luciad.lucy.ILcyLucyEnv)

setLucyEnv

public void setLucyEnv(ILcyLucyEnv aLucyEnv)

Description copied from class: ALcyPrintPreviewFactory

Sets the associated lucy environment.

Specified by:

setLucyEnv in class ALcyPrintPreviewFactory<TLcyPrintContext>

Parameters:

aLucyEnv - The lucy environment.

See Also:

• ALcyPrintPreviewFactory.getLucyEnv()

createPrintPreview

public Component createPrintPreview(TLcyPrintContext aPrintContext,
 ILcdAction aCloseAction)

This function

1. creates all actions using createAction(int, com.luciad.lucy.addons.print.TLcyPrintContext, com.luciad.gui.ILcdAction) with all ID's ending in _ACTION.
2. creates all components using createComponent(int, com.luciad.lucy.addons.print.TLcyPrintContext, com.luciad.gui.ILcdAction) with all ID's ending in _COMPONENT.
3. creates all panels using createPanel(int, com.luciad.lucy.addons.print.TLcyPrintContext, com.luciad.gui.ILcdAction) with all ID's ending in _PANEL.
4. calls createPrintPreviewContent(com.luciad.lucy.addons.print.TLcyPrintContext, com.luciad.gui.ILcdAction), which creates the content of the print preview by laying out all panels created in the previous step.

The Component created in the last step is returned. It is up to the user of this factory to make the returned Component visible in for example a frame or a dialog.

Note that because of this order, panels can be composed of components, and components can use the actions. So the createPanel(int, com.luciad.lucy.addons.print.TLcyPrintContext, com.luciad.gui.ILcdAction) method can use getComponent(int) to retrieve its sub components, and the createComponent(int, com.luciad.lucy.addons.print.TLcyPrintContext, com.luciad.gui.ILcdAction) method can use getAction(int) to retrieve needed actions.

Warning: Should not be overridden without calling the super function.

Specified by:

createPrintPreview in class ALcyPrintPreviewFactory<TLcyPrintContext>

Parameters:

aPrintContext - The print context to use.

aCloseAction - The close action. As the print preview has no idea how it will be represented (in a dialog, in a frame, ...) this action is provided to allow the print preview to close itself.

Returns:

the print preview, created by createPrintPreviewContent(com.luciad.lucy.addons.print.TLcyPrintContext, com.luciad.gui.ILcdAction).

createPrintPreviewContent

protected Component createPrintPreviewContent(TLcyPrintContext aPrintContext,
 ILcdAction aCloseAction)

Retrieves all panels and lays them out in a java.awt.Component. Therefore, this method uses getPanel(int) with all ID's that end in PANEL, and lays out those components in for example a javax.swing.JPanel.

This function should be overridden when the global layout of the print preview dialog needs to be changed, for example when the main panels such as the 'Printer settings' panel, 'Printing area' panel, 'Options' panel and 'Page preview' panel need to be rearranged, or when a new panel needs to be added.

Parameters:

aPrintContext - The print context to use.

aCloseAction - The close action to use.

Returns:

the created content.

createAction

protected ILcdAction createAction(int aID,
 TLcyPrintContext aPrintContext,
 ILcdAction aCloseAction)

Creates an ILcdAction for the given ID.

Parameters:

aID - The id describing which action to create. This is a constant that ends in ACTION.

aPrintContext - The print context to use.

aCloseAction - The close action, contextual information.

Returns:

The newly created ILcdAction, or null.

getAction

protected ILcdAction getAction(int aID)

Returns the ILcdAction for the given ID.

Please refer to createPrintPreview(com.luciad.lucy.addons.print.TLcyPrintContext, com.luciad.gui.ILcdAction) to know when this method can be used.

Parameters:

aID - The id describing which action to return. This is a constant that ends in ACTION.

Returns:

the ILcdAction for the given ID.

createComponent

protected Component createComponent(int aID,
 TLcyPrintContext aPrintContext,
 ILcdAction aCloseAction)

Creates a widget for the given ID. It is safe to use getAction(int) in this method, to build widgets that use an action.

These widgets will typically interact with the properties object of aPrintContext (see ALcyPrintContext.getProperties()). Such a widget could for example be a checkbox that is synchronized with the value of the TLcyPrintAddOn.OVERVIEW_VISIBLE_KEY, or a slider that represents the value of TLcyPrintAddOn.RASTERIZATION_QUALITY_KEY.

Parameters:

aID - The id describing which component to create. This is a constant that ends in _COMPONENT.

aPrintContext - The print context to use.

aCloseAction - The close action, contextual information.

Returns:

The newly created java.awt.Component, or null.

getComponent

protected Component getComponent(int aID)

Returns the java.awt.Component for the given ID.

Please refer to createPrintPreview(com.luciad.lucy.addons.print.TLcyPrintContext, com.luciad.gui.ILcdAction) to know when this method can be used.

Parameters:

aID - The id describing which component to return. This is a constant that ends in COMPONENT.

Returns:

the java.awt.Component for the given ID.

createPanel

protected Component createPanel(int aID,
 TLcyPrintContext aPrintContext,
 ILcdAction aCloseAction)

Creates a panel for the given ID. It is safe to use getComponent(int) in this method, to build panels that are composed of components.

Parameters:

aID - The id describing which panel to create. This is a constant that ends in PANEL.

aPrintContext - The print context to use.

aCloseAction - The close action, contextual information.

Returns:

The newly created java.awt.Component, or null.

getPanel

protected Component getPanel(int aID)

Returns the panel as a java.awt.Component for the given ID.

Please refer to createPrintPreview(com.luciad.lucy.addons.print.TLcyPrintContext, com.luciad.gui.ILcdAction) to know when this method can be used.

Parameters:

aID - The id describing which panel to return. This is a constant that ends in PANEL.

Returns:

the panel as a java.awt.Component for the given ID.
