How can I always show the horizontalHeader, even if the qtableview is empty?

[Zuchao Wang]

Currently when the tableview is empty, the horizontalheader will be automatically hidden. But I want it always shown. Is there anyway to do that?

[high_flyer]

did you try:
pMyTable->horizontalHeader()->setVisible(true); ?

[Zuchao Wang]

yeah, but it has no effect.

Can you show your code?
Is the table generated in code, or designer?

[Zuchao Wang]

Sorry, I cannot show my code.
The table is generated by code, and it's totally following the model/view architecture. Basically it looks lke this:

class A: public QAbstractTableModel{...};
class B: pulbic QSortFilterProxyModel{...};
class C: public QTableView{...};

A a;
B b;
C c;

b.setModel(&a);
c.setModel(&b);

Here c is the table. Everything just works fine, except that the horizontalHeader of c automatically disappears when I hide all columns in c. I just want the horizontalHeader always shown.

when I hide all columns in c

This is not the same as:

Currently when the tableview is empty

Hidden is not same as empty.

You probably will have to manually call showSection() on the hidden columns,when you hide you columns.
