qlistview

I have QListView and QTabWidget inside QSplitter. QListView is using custom model and custom delegates. In delegate I reimplemented paint and sizeHint methods. But when I resize view - height of elements doesn't recalculated. How can I fix it? Sample images: In google I found that it is possible to emit layoutChanged from the model, but I want only current view to be updated, because content of model doesn't change. Delegate code: void ChatItemDelegate::paint( QPainter *painter, const QStyleOptionViewItem& option, const QModelIndex& index ) const { painter->save(); ChatItem *item = static_cast

I'm writing a PyQt application and am having some trouble creating a custom list view. I'd like the list to contain arbitrary widgets (one custom widget in particular). How would I go about this? It seems that the alternative would be to create a table or grid view wrapped in a scrollbar. However, I'd like to be able to take advantage of the model/view approach as well as the nesting (tree-view) support the built-ins handle. To clarify, the custom widgets are interactive (contain buttons), so the solution requires more than painting a widget. Idan K I think you need to subclass QItemDelegate .

Suppose my model has items with the following string for Qt::DisplayRole <span>blah-blah <b>some text</b> other blah</span> I want QTreeView (actually, any item view) to render it like a rich text. Instead, item views render it like a pure text by default. How to achieve the desired rendering? Actually, this is a search results model. User enters a text, some document is searched against that text and the user is presented with search results, where the words being searched should be bolder than surrounding text. serge_gubenko I guess you can use setItemDelegate method of the treeview to setup
