QCcompleter , colum probelm

[wysota]

I can reproduce this error on my installation. It seems that setCompletionColumn() doesn't set a proper model column on the popup. A solution is to call:

((QListView*)cc->popup())->setModelColumn(2);

((QListView*)cc->popup())->setModelColumn(2);

To copy to clipboard, switch view to plain text mode 

The funny thing is, that it should work without it just fine...

This is the code that gets called:

void QCompleter::setCompletionColumn(int column)
{
    Q_D(QCompleter);
    if (d->column == column)
        return;
#ifndef QT_NO_LISTVIEW
    if (QListView *listView = qobject_cast<QListView *>(d->popup))
        listView->setModelColumn(column);
#endif
    d->column = column;
    d->proxy->invalidate();
}

void QCompleter::setCompletionColumn(int column)
{
    Q_D(QCompleter);
    if (d->column == column)
        return;
#ifndef QT_NO_LISTVIEW
    if (QListView *listView = qobject_cast<QListView *>(d->popup))
        listView->setModelColumn(column);
#endif
    d->column = column;
    d->proxy->invalidate();
}

To copy to clipboard, switch view to plain text mode 

So there are three explanations:
1. popup is not a QListView
2. d->column == column
3. QT_NO_LISTVIEW is defined

First two assumptions are false (popup is a list view and d->column != column) and the third seems very unlikely. So there has to be a fourth explanation - something overrides or doesn't allow to change the model column for the listview.

well thanks alot .
it now works , the colum i want appear , but something starnge is happening..
when the list popup , it don't handle keyboard evens well..
for example when i write the first letter , and the list is poped up , i try to move by the keyboard down , it just moves to one item then refuse to go down anymore..
the same happens when i try to go upwards , the pagedown and pageup don't work at all ?
