QTableView, adding headers and content
-
@mrjj , next related question, when I add the rows I use:
lstRow.append(new QStandardItem(strValue));Later once the list is ready to add:
mpsiModel->appendRow(lstRow);The question is how do I get access to the row list when I want to delete each instance of QStandardItem?
Kind Regards,

Hi
Well the models own the items so you dont need to clean up. It will do.
If you want to empty it, you can call clear() on it. -

I want to make it so when I double click a row it selects that row and then signals my application of this.

hi
selecting row:
table->setSelectionBehavior(QAbstractItemView::SelectRows);for nonediting, you can set that on the item
item->setFlags(item->flags() & ~Qt::ItemIsEditable) // we remove the edit flag. there are others flags so we only clear that one out as not to fux up stuff
for the spaces:
QHeaderView* header=tableView->verticalHeader();
header->setDefaultSectionSize(20); // 20 px height for all -

QHeaderView* phvHorizontal(mptvRecs->horizontalHeader()); phvHoriztonal->setDefaultSectionSize(14);However that effects the header width and not the height.

@SPlatten
Hi
The verticalheader() gives access to the "height" -
@mrjj, checking this out now...also I'm using a lambda connection to connect to:
QObject::connect(mptvRecs, &QTableView::doubleClicked, [this, objJSONdataTypes]() { ... });This works, but is there anyway to get access to the parameter associated with the doubleClicked signal from lambda ?
[Edit]...trying
QObject::connect(mptvRecs, &QTableView::doubleClicked, [this, objJSONdataTypes](const QModelIndex& crIndex) { ... });[Edit2], yes that works!

@mrjj , Is there a way to remove the padding which seems to be present above and below the text regardless of the height setting ?
If I use setFixedHeight there are still several pixels above the text.
[Edit] Yes, by using setStyleSheet on header.
