/**
|
||||
* A panel that can be used to implement an administration console. Widgets can be arranged in vertical and horizontal
|
||||
* tabs ("L-shape"). The top-level element is the vertical tab panel. Widgets may either be added directly as the
|
||||
* content of one vertical tab, or a horizontal tab panel can be added as the content widget of a vertical tab, in turn
|
||||
* holding widgets in horizontal tabs.
|
||||
* <p>
|
||||
*
|
||||
* After constructing an instance of this class, there are three ways for adding widgets:
|
||||
* <ul>
|
||||
* <li>{@link #addToVerticalTabPanel(RefreshableAdminConsolePanel, String, Permission)} adds a widget as a content
|
||||
* element of a vertical tab</li>
|
||||
* <li>{@link #addVerticalTab(String, String, Permission)} creates a horizontal tab panel and adds it as a content
|
||||
* element of a vertical tab</li>
|
||||
* <li>{@link #addToTabPanel(TabLayoutPanel, RefreshableAdminConsolePanel, String, Permission)} adds a widget as a
|
||||
* content element of a horizontal tab</li>
|
||||
* </ul>
|
||||
*
|
||||
* Widgets to be added need to be wrapped as {@link RefreshableAdminConsolePanel} holding the widget and receiving the
|
||||
* refresh call when the widget is shown because the user has selected the tab. If the component doesn't require any
|
||||
* refresh logic, an instance of {@link DefaultRefreshableAdminConsolePanel} can be used to wrap the widget.
|
||||
* <p>
|
||||
*
|
||||
* After the widgets have been added, {@link #initUI()} must be called to assemble all tabs for the current user's
|
||||
* roles. The {@link #initUI()} method must be called each time more widgets have been added dynamically.
|
||||
* <p>
|
||||
*
|
||||
* For each widget added, a {@link Permission set of permissions} needs to be specified, any of which is sufficient to
|
||||
* get to see the widget. When the user changes or has his/her permissions updated the set of tabs visible will be
|
||||
* adjusted according to the new roles available for the logged-in user.
|
||||

/**
|
||||
* A panel that can be used to implement an administration console. Widgets can be arranged in vertical and horizontal
|
||||
* tabs ("L-shape"). The top-level element is the vertical tab panel. Widgets may either be added directly as the
|
||||
* content of one vertical tab, or a horizontal tab panel can be added as the content widget of a vertical tab, in turn
|
||||
* holding widgets in horizontal tabs.
|
||||
* <p>
|
||||
*
|
||||
* After constructing an instance of this class, there are three ways for adding widgets:
|
||||
* <ul>
|
||||
* <li>{@link #addToVerticalTabPanel(RefreshableAdminConsolePanel, String, Permission)} adds a widget as a content
|
||||
* element of a vertical tab</li>
|
||||
* <li>{@link #addVerticalTab(String, String, Permission)} creates a horizontal tab panel and adds it as a content
|
||||
* element of a vertical tab</li>
|
||||
* <li>{@link #addToTabPanel(TabLayoutPanel, RefreshableAdminConsolePanel, String, Permission)} adds a widget as a
|
||||
* content element of a horizontal tab</li>
|
||||
* </ul>
|
||||
*
|
||||
* Widgets to be added need to be wrapped as {@link RefreshableAdminConsolePanel} holding the widget and receiving the
|
||||
* refresh call when the widget is shown because the user has selected the tab. If the component doesn't require any
|
||||
* refresh logic, an instance of {@link DefaultRefreshableAdminConsolePanel} can be used to wrap the widget.
|
||||
* <p>
|
||||
*
|
||||
* After the widgets have been added, {@link #initUI()} must be called to assemble all tabs for the current user's
|
||||
* roles. The {@link #initUI()} method must be called each time more widgets have been added dynamically.
|
||||
* <p>
|
||||
*
|
||||
* For each widget added, a {@link Permission set of permissions} needs to be specified, any of which is sufficient to
|
||||
* get to see the widget. When the user changes or has his/her permissions updated the set of tabs visible will be
|
||||
* adjusted according to the new roles available for the logged-in user.
