Nebula XViewer Widget

Advanced TreeViewer Widget

The purpose of the XViewer is to give the application developer a more advanced and dynamic TreeViewer that has the filtering and sorting the capabilities of a spreadsheet while providing the users the ability to customize their table to suit their current needs and save/restore these customizations for future use by individual or group.

Getting Started

XViewer Main

Table Customizations

Provides table customization dialog to allow customization of visible columns, widths and renaming of columns
Easily reorder columns through drag/drop or table customization
Provides mechanism to save and load table customizations so users can easily switch between customizations
Provides mechanism to mark table customizations as individual or global to provide sharing of customizations by users and teams (needs to be backed with shared file system or database)
Provides mechanism to mark table customization as default customization to display whenever this table is shown
Provides ability for multiple XViewer tables to be used within the same application, but provide their own columns and customiztions

Sorting

Sort individual columns (forward or reverse) using data-specific configured sorter for that columns data type
Perform unlimited multi-column sorting by holding Ctrl key down and selecting other columns. Re-selecting a column while Ctrl is held down will reverse the sort for that column

Filtering

Alt-left click on column header (or right-click menu) allows for filtering by column. As many column filters can be added and work together.
Provides simple metrics (bottom status label) to show number of objects loaded, number shown and number selected.
Status label shows filters and sorters that are currently applied to viewer (bottom status label)

Other Capabilities

Provides ability to copy rows, columns or individual cells into buffer for pasting into other applications
Allows for multi-column editing of selected rows/columns
Provides html rendering of currently visible table data
Provides comma separated value export to csv file that can be opened in any spreadsheet application
All the normal capabilities of the existing SWT Tree/TreeViewer have been retained as XViewer is an extension to TreeViewer
