WTableView + VirtualModel + database

Added by Vasiliy Vasiliy almost 11 years ago

Hi, everyone.

I want to make virtual scrolling in WTableView.

Data for this I will get from a database.

I use VirtualModel.cpp example. The "data" function return some data whith specified row and col index.

But I don't want to make query to the database for a single cell. I will make a transitional table in memory for loading data to the WTableView.

How can I call my function for filling my transitional table before "data" function will be called, and how can I get the indexes for needed rows and cells?

Hello Vasiliy,

Dbo's Querymodel solves this through caching. You can take a look at the source of DboQueryModel.

Best regards,

Wim.
