QLayoutPrivate issue

[gimel]

I resolved this issue by

#include <QtGui/private/qlayout_p.h>

#include <QtGui/private/qlayout_p.h>

To copy to clipboard, switch view to plain text mode 

If this will not work, I'll try your solution.

it is bad idea to use Qt's internal code.

Indeed! Thank you.

I'm trying to do the exact same thing. This thread is rather old, but I would be very happy to know how you solved this. I'm struggling with getting the suggestion from "spirit" to work.

You also need to store the widget using addChildWidget(). So the additional functions should look like the following:

void FlowLayout::insertItem(int index, QLayoutItem *item)
{
    itemList.insert(index, item);
}
 
void FlowLayout::insertWidget(int index, QWidget *widget)
{
    addChildWidget(widget);
    QWidgetItem *item = new QWidgetItem(widget);
    insertItem(index, item);
}

void FlowLayout::insertItem(int index, QLayoutItem *item)
{
    itemList.insert(index, item);
}

void FlowLayout::insertWidget(int index, QWidget *widget)
{
    addChildWidget(widget);
    QWidgetItem *item = new QWidgetItem(widget);
    insertItem(index, item);
}

To copy to clipboard, switch view to plain text mode 

P.S. this works for me.
