Hi all,
I am creating a user interface that should display several table views, and for some of them, the headers tend to disappear at some point.
I have several classes, say class1 and class2.
One table view shows information on class1 (1 instance per row)
One table view shows information on class2 (1 instance per row)
A last table view displays a coefficient for each couple (class1, class2). So if I have m objects of class1 and n objects of class2, this last table has m rows and n columns.
Problem is, when I add or remove objects of class1 or class2, the dimension changes. When I add an object, I send signals to execute the functions "beginInsertRows" and "endInsertRows" to the model associated to the "joint table". It works fine, except that the headers disappear when I do that (not always, but most of the time).
Does any one have an idea why this happens? I use Qt 4.0.
Thanks,
xavier
