Building Tree view from Table view which is already build.

[DURGAPRASAD NEELAM]

Hi,

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

Level	         Name	Rank   Sec
0	   	 Rajesh	1        A
1	   	 Krish	2        A
2	         Ram	3        B
1	         Krish 	4        C
0	         Krish	5        B
1	   	 Krish	6        a
1	   	 Krish	7	  A 
0	   	 Rajesh	1        A
1	   	 Krish	2        A
2	         Ram	3        B
0	   	 Rajesh	1        A
1	   	 Krish	2        A
2	         Ram	3        B

Level	         Name	Rank   Sec
0	   	 Rajesh	1        A
1	   	 Krish	2        A
2	         Ram	3        B
1	         Krish 	4        C
0	         Krish	5        B
1	   	 Krish	6        a
1	   	 Krish	7	  A 
0	   	 Rajesh	1        A
1	   	 Krish	2        A
2	         Ram	3        B
0	   	 Rajesh	1        A
1	   	 Krish	2        A
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 :-)
