The grid provides convenient GUI framework for working with data in tabular form. The main design purpose was to present RDBMS records in rows. You can edit in place, add, or delete records. An instance of the ygrid class can be included into any CAPI interface window as an ordinary pane. It requires Ystok-Library and Ystok-Widgets.

Basic Features

Text display, text input, and check button columns.
Enabled or read-only columns.
Ghost columns, i.e. calculated from the values of other columns.
Callbacks on interactive user actions.
Selecting rows with various styles of choice-interaction via a row header.
The width of any column is adjustable separately via a mouse gesture or programmatically.
The height of all rows is the same and adjustable via a mouse gesture or programmatically.
Assigning graphics args (foreground or background color, font etc.) to every cell differentially.
Sorting and filtering rows.
Searching a single column via of a kind of "Find what" dialog.
Standard records menu and toolbar.
Undo changes performed on cell or entire record.
