d/olu_javaman,
yeah..i got ur concept and is almost same to what i've implemented so far.
see the logic i've done:
1) i parse every line i've inserted to map out the identifier and their data types.
i.e, whenever i wrote any declaration statement (like JList list ; ) i record "list" is and identifer of JList etc
that means, i can accomplish what u've said in ur statement no.3) and 4).
2) i create a JList and load the relevant methods of the identifier(before dot) and inserted in an appropriate JScrollPane and finaally inserted it on JpopupMenu. That accomplish ur statement no. 6) and 7)
3) and finally i inserted relevant Listeners to append the text after the dot on my document.
yeah..it's done but there's one problem
when i insert the selected text from the JList, my caret needs to blink on the last offset.right???
(the caret is visble on the last offset of the line, but it's not blinking)
but it's not blinking. i think i got nervous in transfering the focus to the textArea. just give me some hint on this issue.
And I'm really thankful for ur good suggestion.
regards,
sushil
