Constructor Detail

MessagePage

public MessagePage()

Default constructor. Creates a MessagePage using the message page view identifier.

MessagePage

protected MessagePage(ViewId viewId)

Creates a MessagePage using thle specified ViewId.

MessagePage

protected MessagePage(ViewId viewId,
                      javax.swing.Icon icon)

Creates a MessagePage using the specified ViewId and Icon.

MessagePage

public MessagePage(ViewId viewId,
                   javax.swing.Icon icon,
                   boolean addPage)

Creates a MessagePage using the specified ViewId and Icon.

MessagePage

protected MessagePage(ViewId viewId,
                      javax.swing.Icon icon,
                      boolean addPage,
                      boolean showStyledText)

Deprecated. use #MessagePage(ViewId,Icon,boolean). The showStyledText parameter has been deprecated, since all message pages are now capable of showing styled text by default.

Creates a MessagePage using the specified ViewId and Icon.

Some subclasses will pass false for the addPage argument, which means DO NOT add the page to the log manager during the execution of the constructor. The reason why a subclass would pass false is because they are overriding methods which are called during the addPage process and the overriding methods depend on field initialization which does not take place until after the super constructor returns. For example, a subclass which overrides getToolTip will likely want to pass false for the addPage argument.

getToolbar

public Toolbar getToolbar()

Description copied from class: View

Get the toolbar associated with this view.

Overrides:

getToolbar in class View

setToolbarVisible

public void setToolbarVisible(boolean visible)

Overrides:

setToolbarVisible in class View

updateVisibleActions

public void updateVisibleActions(UpdateMessage updateMessage)

Description copied from class: View

Called when the IDE or an extension requests that the View updates the enabled state of any actions that are visible on screen. Typically this will involve updating actions that are in visible toolbars. If a View contains or manages other nested instances of View, the outer call to updateVisibleActions should propagate inward to call the updateVisibleActions of all visible, nested Views.

Overrides:

updateVisibleActions in class View

Parameters:

updateMessage - information on what is triggering the update. Implementations may make use of this information to decide whether or not an update is necessary, since updating the enabled state of a toolbar button may be a lengthy operation. For example, buttons that control a remote debugger would involve network I/O and evaluating their updated state could be avoided if the updateMessage indicates that the source of the update is not relevant to the debugger.

getToolbarSearchField

public SearchField getToolbarSearchField()

Get the SearchField that searches the log. The SearchField is already added to the toolbar by default. Subclasses may remove it, move-it or re-add it as they see fit.

Returns:

the toolbar SearchField
