Hi,

I have already build table view (by customizing QAbstractItemModel & QTableView).
My table view looks as below


Qt Code: 
  1. Level	         Name	Rank   Sec
  2. 0	   	 Rajesh	1        A
  3. 1	   	 Krish	2        A
  4. 2	         Ram	3        B
  5. 1	         Krish 	4        C
  6. 0	         Krish	5        B
  7. 1	   	 Krish	6        a
  8. 1	   	 Krish	7	  A 
  9. 0	   	 Rajesh	1        A
  10. 1	   	 Krish	2        A
  11. 2	         Ram	3        B
  12. 0	   	 Rajesh	1        A
  13. 1	   	 Krish	2        A
  14. 2	         Ram	3        B
To copy to clipboard, switch view to plain text mode 


Now based on the level column I need to build the tree, Is it possible to re use the same model(from table view) and create tree view based on level column ?
or do I need to create separate new model for tree again. If it is possible please let me know what i need to implement for this.

Tree view : all the Level 0's are parents, followed by 1's are childs of 0's and 2's are childs of 1's.

Thanks in Advance :-)
