HiGrid Examples

Examples that come with JClass HiGrid. Examples are organized by major feature categories, shown in the leftmost column of the table.
Notes:

This version of JClass currently does not work in some browsers because of a lack of native Java 2 support. Try using the Java 2 plug-in instead.

Some demos require that files are loaded, which requires a special browser file access permission. You need to grant this permission in your browser in order to see the demo run properly.

Category	Example	Description
Base Examples that are the basis for the remaining examples.	Base	The primordial example. Many of the remaining examples subclass this example. It shows how to set up a simple connection to the DataSource.
	Base Button	Another primordial example that subclasses Base Example. It adds a button to the layout to provide user interaction for some of the remaining examples.
Data How to handle display of exceptions encountered by HiGrid.	Foreign Key Editor	This example shows how to add combobox drop-downs for fields which are foreign keys to other tables.
Exception How to handle display of exceptions encountered by HiGrid.	Exception Message	This example contains a list of the events thrown by the data model and the grid, and it presents two ways of handling exceptions. By default, HiGrid presents exception messages in a dialog window. You can provide your own mechanism by implementing the HiGridListener interface and providing code there to deal with the exception.
Format Cell/Grid Formating examples.	Auto Traverse	This example shows various options available as to how many and which levels the grid will automatically expose.
	Dynamic Format	Usually, the formatted colors, etc. of the grid are set at design time. This example shows how to change the background colors of a table from their defaults to either a) alternating colors, b) colors based on the data within the row, or c) random colors.
	FormatNode Event	This example shows how to catch the FormatNode creation event. This allows various dynamic, run-time formatting effects.
	Node Renderer	This example shows how to modify the rendering of the nodes that expand and collapse grid levels. It also shows how to change the indent level to minimize the amount of horizontal space used by the grid.
Menu Customize HiGrid's popup menu.	Popup Menu	HiGrid provides a built-in popup menu to allow the user to access many standard features, such as insert/delete/update/print etc. This example shows how to select among the standard menu schemes, and even how to replace portions of the standard menu with your own menu items.
Sort Customizing the way sorting is done and displayed within HiGrid.	Custom Sortable	This example shows how to replace the default sorting behavior for a data type. In this case, the default sorting for Dates is changed from Day, Month, Year to Month, Year, Day. This new sorting behavior can be applied to all columns of this data type, or to a specific column only.
	Sort Icon	This example shows how to replace the default sort icon displayed by HiGrid.
Summary Using HiGrid's aggregation support to display summary information.	Summary	This example shows how to add summary data to the grid. Summary data can consist of footers, before details and after details. In this example, footer and before detail information is added when the button is clicked.
	Summary Unbound Data	This example extends the Summary Example by adding computed summary information that does not exist in the DataSource. This type of information is called unbound data.
Validation Customizing HiGrid's data validation.	Cell Validation	This example shows how to do cell level validation. It does two types of validations: it won't accept an empty field and it validates the PurchaseOrderNumber column of the top grid level to prevent any modifications when the first character changes.
Validation Customizing HiGrid's data validation.	Row Validation	Often, the value of one field within a row needs to be validated with respect to another in the same row. This example shows how to do row level validation. It will reject changes where the RequiredDate comes before the OrderDate.
Visual Examples that show off some neat visual effects.	EditorRenderer	This example shows how to override the default editor/renderer associations with data types.
	Fly Over	Tooltips are a much requested feature in many applications. This example shows how to implement fly-over tooltips, where the tip displays information that describes the row the mouse is over.
	Folder Icon	To add a little pizazz to your application, you can change the look of the "+/-" symbols that indicate whether a table is expanded or collapsed. This example shows how to select one of the many preset folder icon styles, and even how to construct a brand new one.
	List Mode	This example shows how to simulate a list mode for HiGrid, (i.e.), to make it behave somewhat like a list box. The cell editor is always hidden, and a single click selects a row.
	Row Tip	The default colors or position of the rowtip that appears on the vertical scrollbar sometimes needs to be customized. This example shows how to change the attributes of the popup rowtip, how to position it, size it and set its text.
	ScrollBar Position	When placing a component within a web page, one must predetermine the maximum size of the component. Since HiGrid can display a dynamic amount of data, the scrollbars may often be placed beyond the borders of the component. This example shows how to place the scrollbars on the left and top sides of the grid to handle this issue.
	Single Selection	This example shows how to allow at most one row to be selected by the user.
