Set row highlighted when application start in QTableWidget

[maxmotor]

Hello devs!

I am currently trying to develop an application where I have a QTableWidget.
This tableWidget has 2 columns (containing text).
The selection behaviour is set to "QAbstractItemView::SelectRows" - which selects the entire row instead of the single cell.
Now I'm trying to set the first row as highlighted when my application is launched. I have had no luck so far though.

Can anyone help me out?

Thank you for your time.

You can use "void QTableWidget::setCurrentCell ( int row, int column )":http://doc.qt.nokia.com/latest/qtablewidget.html#setCurrentCell with selection mode set to QAbstractItemView::SingleSelection or QAbstractItemView::ExtendedSelection

That doesn't work for me. Guess it has something to do with me selecting an entire row?

When do you call this method?
If you do it in the constructor, it will not work, as the input focus has not moved there...

Yes, I call my QTableWidget setup method from the constructer.

Here is some of my code:
@
Setup::Setup(QWidget *parent) :
Parent_ui(parent) {

ui.setupUi(this);
populateList();
}

void Setup::populateList() {

ui.tableWidget->setColumnCount(2);
ui.tableWidget->setColumnWidth(0,(ui.tableWidget->width() - 152));
ui.tableWidget->setColumnWidth(1,150);
ui.tableWidget->setShowGrid(false);
ui.tableWidget->verticalHeader()->hide();
ui.tableWidget->horizontalHeader()->hide();
ui.tableWidget->setSelectionBehavior(QAbstractItemView::SelectRows);

... //items are added to the QTableWidget
}
@

So I cant call setCurrentCell from my populateList method?

How do I handle this problem?

Thank you for your time!

No, you can not. The problem is, that at that time, your form is not even showing yet.
What you might do, is something like this:

@
Setup::Setup(QWidget *parent) :
Parent_ui(parent) {

ui.setupUi(this);
populateList();
//trigger 2nd phase of initialization when the eventloop is running
QTimer::singleShot(0, this, SLOT(initializePhase2()));
}

void Setup::initializePhase2()
{
//set which row to highlight.
}
@

Don't forget to mark initializePhase2 as a (private) slot in your header, and include the Q_OBJECT macro in your class definition, of course. Sorry for the inconvenience...

bq. Sorry for the inconvenience…

I am grateful for your help - that goes to all of you. :)

The cell row is now highlighted grey - what method could set the row as... hmm.. is it called focus? You know like when you click a cell and it turns blue.

Again - thank you for your time!

Make the table widget have the focus. See QWidget::setFocus().

BTW: note that there is a difference between the active cell and selected cells. They may be rendered differently.

Oh god... I'm sorry for my ignorance.
I answer my own question in my previous post. Sorry.
