Regions

Query Region In OA Framework

by

A query region is basically an extension of the stackLayout region.
A query region can contain the following:
1. Simple search panel
2. advanced search panel
3. a results table
4. Other elements as indexed children

Simple search panel can contain any of the following regions
a) defaultSingleColumn
b) defaultDoubleColumn
c) defaultStack
d) defaultFormStack elements.

The advanced search panel can contain
a) advancedSearch element.

The results of a query are rendered using either a HGrid or a table. The table or HGrid elements are added as indexed children of the query region.

A query region can have three types of search panels as listed below.
Simple
Advanced
Customize

Also the query region runs in three modes:
1. Default mode
2. Results Based Search (RBS) mode
3. Auto Customization Criteria (ACC) mode.

Default mode: Developer is responsible for defining the search panels and binding the results of the search to the results table/HGrid.

Results Based Search (RBS) mode: Search panel is created dynamically using the queryable property of the region items inside the nested table or HGrid indexed children

Auto Customization Criteria (ACC) mode: You have the flexibility of defining your own UI for the search panels, but the binding is powered by the framework as long as items on the panels are mapped to items in the results table/HGrid.

Set the User Personalization property of the table/hgrid region (under the query region) to True if you want to support user-personalizable searches which are surfaced in a Views panel.

Row Layout Region In OAF

by

In oracle application framework page the OAF RowLayout region is used which will hold CelFormat inside i.e. as a child to it.

RowLayout region can be defined as an independent region or it can be a child of a tableLayout/ advanceTable region to create a row of a table/advanceTable.

RowLayout provides horizontal alignment of items or regions as these items or regions will be under cellFormat and rowLayout holds cellFormat in a horizontal line.
Hence row contains cell and cell in-turn contains items to it.

We use rowLayout only when other layouts are not supporting the requirement in a standard way i.e. not following the Oracle BLAF UI guidelines.

How to create rowLayout Region in OAF page?
Creating a rowLayout region on an Oracle Apps Framework page is simple. Just follow the steps given below.
1. Create a region on an OAF page using JDeveloper
2. Set the style property to rowLayout.
3. Set the properties of the newly created rowLayout region according to the requirement and the standards of Oracle Apps Framework.
4. Create cellFormat region as a child of rowLayout.
5. Create items or regions of any style as children in cellFormat region.

Sub Tab Layout In OAF

by

The subTabLayout region has a child called “subTabs” that takes a subTabBar bean.
subTabBar bean contains link elements as its indexed children. subTabBar is rendered once on top.

The number of indexed children of subTabBar, which are the link elements, should be equal to the number of indexed children of the parent subTabLayout.
The link elements are used to switch between the indexed children of the subTabLayout.
