[Solved] Help using QStandardItemModel

[dvillalobos]

Hi, I have the following code, taken from SpinBoxDelegate Example, but in my example, the QTableView does not shown the data. Any clue?

Best regards.

David

@
mdiMain = new QMdiArea;
mdiMain->setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded);
mdiMain->setVerticalScrollBarPolicy(Qt::ScrollBarAsNeeded);
setCentralWidget(mdiMain);

QMdiSubWindow *sub = new QMdiSubWindow;
QTableView *table = new QTableView;
QStandardItemModel model(4, 2);
for (int row = 0; row < 4; ++row)
for (int column = 0; column < 2; ++column)
model.setData(model.index(row, column, QModelIndex()), QVariant((row+1) * (column+1)));
table->setModel(&model);
sub->setWidget(table);
sub->show();

setRole for your data. For example Qt::DisplayRole.

@
model.setData(model.index(row, column, QModelIndex()), QVariant((row+1) * (column+1)), Qt::DisplayRole);

Hi stima_ua, thanks for your replay, but it did not work.

How long is your model alive!?!?

Hi Scylla, thanks for your replay.

What do you mean how long is my model alive?

I have noticed that in my example, when I refresh the model contents by filling it, the QTableView seems to be filled but just for about a second.

I don't know where your code is located. If it's not in the main() your model will die on the end of the scope. That's what I mean.

So if i's not your issue, please show more code.

Great!!! Scylla.

You hit it, :-) in my example model has to be declared in the same place mdiMain was decladed.

I really appreciate your help and stima_ua, thanks for your help too.

@
mdiMain = new QMdiArea;
mdiMain->setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded);
mdiMain->setVerticalScrollBarPolicy(Qt::ScrollBarAsNeeded);
setCentralWidget(mdiMain);

QMdiSubWindow *sub = new QMdiSubWindow;
QTableView *table = new QTableView;
model = new QStandardItemModel(4, 2);
for (int row = 0; row < 4; ++row)
for (int column = 0; column < 2; ++column)
model.setData(model.index(row, column, QModelIndex()), QVariant((row+1) * (column+1)));
table->setModel(&model);
sub->setWidget(table);
sub->show();

Now, can I add a QIcon to the vertical o horizontal headers like in QTableWidget? I mean, can I do something like this with QTableView?

@
result->setHorizontalHeaderItem(row, new QTableWidgetItem(QIcon(":/MyIcon.png"), "Header"));
@

[Scylla]

somthing like that:
@m_model->horizontalHeaderItem(0)->setIcon(QIcon(":/ressources/clean.png"));@

[stima_ua]

Read manual.
@
QTableWidgetItem *item = new QTableWidgetItem;
item->setData(QVariant(), Role);
item->setIcon(path);
