Thanks Boron and JPN for your useful post .....

But I have an another issue, as I have created a huge number of same type controls, QT Designer will give different names for those controls automatically. Can I make those like an array. I can do the same thing by creating LineEdit (say for examples) array and copy those objects into that array and can use them sequentially, but is there any way to do this in designer by default ???? (It can reduce my code size)

Thanks in advance ......
