Hi,

This will depend on your widgets and what their content. It will also depend on the device that runs your application. But more seriously, unless you are under very high memory constraints you should allocate the widgets commonly used from the start and the ones that are less often used when they are needed.

@Joachim-W Then please mark this topic as solved, thx.

How are you querying the database with Qt ?

No problem, that's an information that might be useful to someone else :)

What was taking so long ?

Since you have it working now, please update the thread title prepending [solved] so that other users may know a solution has been found :)

Ok thanks, I'll look at it.
Cheers
