Dock widgets reusage about kddockwidgets

[iamsergio]

Simply dockWidget->setWidget(newWidget) should work
If it doesn't then it's a bug I need to fix, can you check if it works ?

[arietto]

Simple setWidget calls abort: Q_ASSERT(w && !d->widget);

Would you like to delete previous widget in setWidget?
At the moment I have to delete the whole dock instead of resetting new child widget.
if (m_dock)
{
m_dock->forceClose();
delete m_dock;
m_dock = nullptr;
}

does simply removing the assert work ?
I'll have a look on monday

[arietto]

Simple removing the assert will lead to memory leak, because old instance won't be deleted.
void DockWidgetBase::setWidget(QWidgetOrQuick *w)
{
Q_ASSERT(w && !d->widget);
qCDebug(addwidget) << Q_FUNC_INFO << w;

d->widget = w;
setSizePolicy(w->sizePolicy());

Q_EMIT widgetChanged(w);
setWindowTitle(uniqueName());

}
