Qt Model-View update view?

Question

I have a model which is updated dynamically not related to the view. Which method should be called on the view to show the current models data?

Example:

Answer 1

Model must emit signals to notify views when its data changed. Choose appropriate signals depending on how exactly data is changed:

• dataChanged signal forces view to update specific cells, but not to create or remove cells.
• layoutAboutToBeChanged and layoutChanged signals forces view to update everything.
• signals about adding or removing rows and columns forces view to update accordingly.
