Table users can also use a mouse to navigate around a table, perform selection, and initiate the editing of a cell.
If a user is editing or entering text in a cell and uses the mouse to move the focus out of the table, the current edit is completed. If an integer or float cell was being edited and the user entered an illegal value, the table will beep and leave the original value unchanged. Then the focus is moved to the new location.
When the user double-clicks on a cell, ESL generates a response. Your application can decide the proper behavior. For example, the following code will cause a table to switch to edit mode in response to a double-click:
response to table on button1 double click
if (xcoord != 0 and ycoord != 0) then
make object edit
else
# Did not double click in a cell.
end if
See Adding Double-Click Behavior for a complete example.
