QModelView update

[bunjee]

Hey there,

I've searched a bit on the forum,

I'm not sure how to update the model from its delegate edit event.

bool ZeChatRoom_delegate::editorEvent(QEvent *event, 
										QAbstractItemModel *model, 
										const QStyleOptionViewItem &option, 
										const QModelIndex &index)
{
	const ZeChatRoom_model* modelData = static_cast<const ZeChatRoom_model*>(index.model());
	ZeChatRoom_data * chatData = index.data().value<ZeChatRoom_data *>();
 
	if (event->type() == QEvent::MouseButtonDblClick)
	{
		//QMouseEvent *mev = (QMouseEvent*)event;
 
		modelData->getService().
			  OpenChat(chatData->getRoomName() + '@' + modelData->getServer());
 
		chatData->setClicked(true);
 
// Hey view could you update your display please ?
 
	}
	else if (event->type() == QEvent::MouseButtonRelease)
	{
		chatData->setClicked(false);
 
// Hey view could you update your display please ?
	}
	return false;
}

bool ZeChatRoom_delegate::editorEvent(QEvent *event, 
										QAbstractItemModel *model, 
										const QStyleOptionViewItem &option, 
										const QModelIndex &index)
{
	const ZeChatRoom_model* modelData = static_cast<const ZeChatRoom_model*>(index.model());
	ZeChatRoom_data * chatData = index.data().value<ZeChatRoom_data *>();

	if (event->type() == QEvent::MouseButtonDblClick)
	{
		//QMouseEvent *mev = (QMouseEvent*)event;

		modelData->getService().
			  OpenChat(chatData->getRoomName() + '@' + modelData->getServer());

		chatData->setClicked(true);

// Hey view could you update your display please ?

	}
	else if (event->type() == QEvent::MouseButtonRelease)
	{
		chatData->setClicked(false);

// Hey view could you update your display please ?
	}
	return false;
}

To copy to clipboard, switch view to plain text mode 

Thanks.

The delegate should use QAbstractItemModel::setData to modify the model (or some other custom method the model provides and that emits dataChanged()). Emition of dataChanged() signal will cause the view to redraw the item.

Will do, thanks.
