Regions

Header Region In OAF

by

In oracle application framework page we create an OAF Header region to give separate title of the page to give the information of the page functionality to the user.
By using Header region, page content and the header region gets seperated/partitioned for more clear information display.

Header region is also used for some important message display on the Oracle application framework page like Error, Warnig, Information, etc at the top of the page.

By use of Header region, the page level action buttons/links will be displayed both at the top of the page and the bottom of the OAF page.

Note: Header element does not support styleClass attribute.

HGrid Region In OA Framework

by

As from the name hgrid itself, it suggests hirarchy grid.

In an oracle application page OAF Hgrid region is used when the data needs to be represented in a hirarchical/tree struture.

You can use the Tree region to represent the tree structure but tree region in OAF emphasis on the relationship of the objects of the hierarchy.

You can use Hgrid to display the hirarchical structure along with the detail information of each row/node. It gives the priveledge of modifing the hierarchy by performing the action as add, delete, update, etc.

Hgrid has 2 special columns:

1. Focus Column.
2. Object Hierarchy Column.

1. Focus Column: In the Focus column we have focus icon, by using focus icon we can set the particular node as the new root of the tree.
2. Object Hierarchy Column: In object hierarchy column, it specifies the current tree node of the tree and gives the priveledge to expand/collapse the node.
When we expand the node, then we will be able to see the children of that respective node also known as zoom in and when we collapse the node, then we hide the children of that respective node also known as zoom out.

At the top of the Hgrid we also have the links to expand/collapse the complete structure of the current focus root node.

Whenever we choose expand functionality, if the number of children exceeds the record limit Navigation link appears and then the excess records are handled by using the navigation buttons i.e. Next or Previous.

Hide Show Region In OAF

by

In oracle application framework page, to provide the functionality to hide and show the items and (or) regions we use HideShow region, i.e. all the items or region, which should be displayed or hidden, should be a child of a region which will have a hide/show control.

By using hode/show control we can hide or show a part of the section of information or the entire section.

Suppose you want to hide or show details of a particular object in an OA framework page, hide/show region can be used.
You can use hide/show region when you want to hide or show the graph, which is present in an OAF page.
You can use this even when a row of a table needs to hide and shown on some action on OAF page.

Hide/show region can only provide its functionality on a single page at multiple parts.
Nesting can also be done.

Hide Show Header Region In OAF

by

In oracle application framework page, to provide the functionality to hide and show the items under a header we use HideShowHeader region.

In both the case of toggling i.e. hidden or shown header text will remain as it is.

In HideShowHeader region we can add items as we add in Header region.

Please refer Header region for more information on the properties of Header region.

Labeled Field Layout In OAF

by

The labeledFieldLayout region lays out its children in columns; one column is for the “labels” and the other for the “fields“, with a gap in between.

The children are laid out across and down, the first child in each row takes the “label” position and the second child takes the “field” position. The contents of each row are centered in the available space.
The “labels” are always right aligned, and the “fields” left aligned.
With multiple columns, the children continue to be layed out across and down. For example, with two columns, the third child will be used as the label for the first row and second column.

It also has support for the inline messaging beans where each inline messaging bean will automatically occupy both a “label” and “field” position.

Corresponding web bean: OALabeledFieldLayoutBean

Note: The labeledFieldLayout component has been deprecated; use the messageComponentLayout component instead. Please refer to the messageComponentLayout section for information about messageComponentLayout.
