Qt with vertical scroll

[psarangi]

hello,

I am new to QT and trying my hand in tableview. I have huge data but want to show 1-10 in a table and want to use scroll bar when items will get added up. My question is .. is there any way that i can get to know that from which index to which index i am currently seeing in my table.
Basically I want to know how do i make a view of my table dynamic to fetch and display dynamic data.

Kindly suggest me ..


Thanks ... :)

The easiest way if if you know the amount of items before hand.
In this case you can just implement a table model and let rowCount() return that number. Qt's table view will only retrieve that it needs for displaying.

Thank you !!! :)

It means that we have to maintain a table internally, which will keep the mapping between a view and the data.

Depending on your data it might be possible to further optimize this using canFetchMore() and fetchMore(), but of course also more complex.
