QTableView, adding headers and content

SPlatten

@mrjj , did you mean TreeView or are you just trying to confuse me...more ? :)

mrjj

Sorry :)
I meant TableView. (no trees)

@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?

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.

SPlatten

@mrjj , thank you.

@mrjj , A few more tweets, each row has a lot of space and padding top and bottom of each row, including headers, I would like to remove this and also I would like to disable editing of the cells.

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

@SPlatten

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

SPlatten

@mrjj ,the headers I want to resize are the horizontal headers, I tried:

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!

SPlatten

@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.
