abstract class EnsPortal.Template.viewerPage extends EnsPortal.Template.standardPage

Base class for viewer-style pages.

These are pages that let the user view a list (such as messages or contents of queues) and select search criteria. Subclasses must override and provide items as follows. See the EnsPortal.EventLog class for an example; there are also others.

Subclasses must provide a searchPane, resultsPane, and detailsPane. The resultsPane should contain a and the detailsPane should contain an with a callback. Subclass must not provide a contentPane.

Note the parameters that identify the id values for the results table, page size counter, and page number counter field. These string values must match the corresponding actual id values for these components in the searchPane and resultsPane. You can set new values for the ids in your subclass if you like. Be sure to set a detailsWidth value, which will interplay with the width of the HTML contents of the detailsPane. It is a good idea to put static widths on the HTML contents of the detailsPane and have them scroll in x and y. See the EnsPortal.EventLog class for an example; there are also others.

The detailsWidth and the width of the HTML contents of the detailsPane will interact with what width you give to the menuPane style which affects the searchPane width.

In the resultsPane, there must be a . The must provide onselectrow="zenPage.selectItem(zenThis)" and onmouseoverClass="tpMouseOver". The should also provide a tableName, even if that doesn't happen until %OnAfterCreatePage, as in EnsPortal.BPInstances.

The subclass must provide an onSelectItem() method. onSelectItem() gets called automatically by the superclass method selectItem().

Subclasses should use getResultsTable() to get the handle of the results table object with no row selection made.

The main

inside the searchPane must have the id value "searchForm".

The search method that gets invoked upon user actions must be called doSearch(). The doSearch() method itself is provided in the superclass.

Subclass should implement an onAfterPageChange() method that does any actions that the page should do each time the display changes (that is, after each search). For example, a subclass might want to force certain expandos to remain open to permit easy access to the fields found there. There is no need to worry about updating the page number, however. That happens automatically.

Subclass should implement an onSearchHandler() method that doSearch() will invoke automatically. Its purpose is to get all the criteria for the search from the form fields. See the EnsPortal.EventLog class for an example; there are also others.

Subclass should implement a GetColumnsAndFrom(timeFormat) method to insert the table name and correctly formatted time string, as well as all desired columns. See examples.

The page size field should have value="#(%page.pageSize)#". The page number field should have value="#(%page.currentPage)#".

• property detailsWidth as %ZEN.Datatype.integer(MAXVAL=80,MINVAL=5) [ InitialExpression = 30 ];
Value to indicate the percentage of the horizontal screen which should be devoted to the details panel (if it is visible). This is exposed as a client-side property for the layout code to use the value.

Hovertext used for detailsExpander Arrow
• property hideSearchMsg as %ZEN.Datatype.caption [ InitialExpression = $$$Text("Hide Search") ];

Flag to indicate whether this is the first page of results. The flag is updated on the client after searches have completed.
• property isLastPage as %ZEN.Datatype.boolean;
Flag to indicate whether this is the last page of results. The flag is updated on the client after searches have completed.
• property lblDetails as %ZEN.Datatype.caption [ InitialExpression = $$$TextJS("Details") ];
• property msgCloseDetail as %ZEN.Datatype.caption [ InitialExpression = $$$TextJS("Close this detail box.") ];
• property pageId as %ZEN.Datatype.string;
Page identifier used with temp global for cancelling search

Id of the results tablePane
• property searchCriteria as %ZEN.proxyObject;
Search criteria from the client.
This is a proxy object whose contents are filled in from the search form by the doSearch method. It is expected that the search query will use this information to determine what results to display.
• property searchJob as %ZEN.Datatype.string;
This is the $Job of the process running the search. It is used by the Cancel search process. If it is -1 then it indicates a Cancel has been issued. It is reset to '' when Search finishes.

• property tablePaneUsesSQLAttrib as %ZEN.Datatype.boolean [ InitialExpression = 0 ];
Flag to indicate whether the tablePane uses the 'sql' attribute to construct queries during normal query execution. This flag determines whether the value of the 'sql' property should be set to '' (empty string) on the client after changing between pages. Initialize (or set) this property to 1 (on the server) or true (on the client) to avoid having the value reset on the client. Under normal operation the property is cleared after each page change occurs.
• property tempPortalNode as %ZEN.Datatype.string;
This is the temp global used for cancelling search

Methods

• method %OnAfterCreatePage() as %Status
Show/hide the toggle buttons

Get the (localized) title string for the page. This should be implemented in a subclass.
• method DrawDetailsContent(pID As %String) as %Status
Write out details for the given item. This should be overridden within the subclass.
• method GetColumnsAndFrom(timeFormat As %String) as %String
For tablePanes which require a constructed SQL query when paging, this callback supplies the columns and FROM portions of the query.
• method GetRemoteSearchJob(pRemoveTempData As %Boolean = 0) as %String [ ZenMethod ]
• method OnGetRibbonInfo(Output pDisplay As %Boolean, Output pViewIcons As %List, Output pSortOptions As %List, Output pSearchBox As %Boolean, Output pRibbonTitle As %String) as %Status
