I am creating a table using WIDGET_TABLE(). All I want to know is which cell the user selected.
WIDGET_TABLE() has several keywords specifying which events will be captured.
/ALL_EVENTS
/CONTEXT_EVENTS
/KBRD_FOCUS_EVENTS
/TRACKING_EVENTS
The documentation for /ALL_EVENTS says "Set this keyword to cause the table widget to generate events whenever the user changes the contents of a table cell."
Here are my quibbles:
1. The name of the /ALL_EVENTS keyword is misleading since it doesn't include all events -- i.e. it doesn't include context events or keyboard focus events or tracking events.
2. The documentation is misleading because I need to use /ALL_EVENTS just to learn which cell the user selected -- even though I don't want the user to be able to change the content of a table cell.
So right now I use /ALL_EVENTS and ignore any event unless the TYPE keyword in the returned event structure has a value of 4 (indicating cell selection) and I ignore all eight other possible values of TYPE. This works but is there any way to specify that I don't want the user to be able to modify the cell contents? Thanks, --Wayne
