Body
I have a <code>QGridLayout</code> where I add my custom <code>QWidgets</code>. When I try to delete all of them they are supposedly removed from the layout (as the function <code>layout.count()</code> returns 0) but they are still shown in the interface and I can interact with them. Here you have the way I add widgets: <pre><code>void MyClass::addCustomWidget(CustomWidget *_widget, int r, int c) { layout->addWidget(_widget, r, c); _widget->show(); } </code></pre> And here the way I delete them: <pre><code>void MyClass::clearLayout() { qDebug() << "Layout count before clearing it: " << layout->count(); int count = layout->count(); int colums = layout->columnCount(); int rows = layout->rowCount(); int i=0; for(int j=0; j<rows; j++) { for(int k=0; k<colums && i<count; k++) { i++; qDebug() << "Removing item at: " << j << "," << k; QLayoutItem* item = layout->itemAtPosition(j, k); if (!item) continue; if (item->widget()) { layout->removeWidget(item->widget()); } else { layout->removeItem(item); } qDebug() << "Removed!"; } } qDebug() << "Layout count after clearing it: " << layout->count(); } </code></pre> Any kind of help or tip to delete items/widgets correctly from a QGridLayout? P.D. : I have seen on the internet that a lot of people deletes the widget directly (delete _widget) after removing them from the layout. In my case it is not possible as I need to mantain that widgets in memory.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
