How to let column's width fit to the window's width in QTableView?

pico

Hi, Sir:
I apply QTableView and QStandardItemModel to setup a data viewer.
However, I failed to let the width perfect.
Could you teach me what I do wrong??

The codes are below:
@
TableViewTest::TableViewTest(QWidget *parent) :
QWidget(parent),
ui(new Ui::TableViewTest)
{
ui->setupUi(this);
mQStandardItemModel = new QStandardItemModel(this);
QString a[10] = { "aaa","bbb", "afa","bfb","ada","bdb","aea","beb","aga","bgb",};
QStringList * mStrList = new QStringList[100];

QTime time = QTime::currentTime();
qsrand((uint)time.msec());
int ch;
for(int i = 0; i < 100; i++){
    mStrList[i] << QString("%1").arg((qrand() % 987)%4);
    for(int j = 0; j < 10; j++){
        ch = (qrand() % 10);
        mStrList[i] << QString("%1-%2").arg(a[ch]).arg('a' + j + 1);//a[j];
    }
}

setParsedData(mStrList,100);

}@

========================================================
@
int TableViewTest::setParsedData(const QStringList *a, const int b)
{
QList <QStandardItem *> col;
for (int i = 0; i < b; i++){//i+=30){
QStandardItem * row = new QStandardItem(QIcon(icon), a[i].at(1));
col.append(new QStandardItem(a[i].at(2)));
mQStandardItemModel->appendRow(row);
}
}
mQStandardItemModel->appendColumn(col);
ui->tableView->setModel(mQStandardItemModel);
return 0;
}
@

In ui file,
@
void setupUi(QWidget *TableViewTest)
{
TableViewTest->resize(400, 300);
horizontalLayout = new QHBoxLayout(TableViewTest);
horizontalLayout->setSpacing(6);
horizontalLayout->setContentsMargins(11, 11, 11, 11);
horizontalLayout->setObjectName(QString::fromUtf8("horizontalLayout"));
tableView = new QTableView(TableViewTest);
tableView->setObjectName(QString::fromUtf8("tableView"));
tableView->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
tableView->setEditTriggers(QAbstractItemView::NoEditTriggers);
tableView->setShowGrid(false);
tableView->setGridStyle(Qt::NoPen);
tableView->setWordWrap(false);
tableView->setCornerButtonEnabled(false);
tableView->horizontalHeader()->setHighlightSections(false);
tableView->verticalHeader()->setVisible(false);
tableView->verticalHeader()->setHighlightSections(false);

    horizontalLayout->addWidget(tableView);

did you try to call

@
ui->TableViewTest->resizeRowToContents();
ui->TableViewTest->resizeColumnsToContents();
@

after filling in the data?

giesbert

additionally, you can automate this:

@
ui->TableViewTest->horizontalHeader()->setResizeMode(QHeaderView::ResizeToContents);
@

see

"QTableView":http://doc.qt.nokia.com/4.7/qtableview.html#resizeColumnsToContents

Hi, Gerolf:
Yes, I did try that already. But, it doesn't work as what I want.
There are two columns in my window.
And, the contents in each column are too long to apply your way.
(If I use that, the column one will fill all window)
So, could you please share me another possibility?

Thanks a lot.

Hi, Gerolf:
The problem is solved!!
I try another way, and I use
@
ui->tableView->horizontalHeader()->setResizeMode(QHeaderView::Stretch);@
Then, it works...

So, thanks for your reminding. I check QHeaderView and get the idea.

Thanks a lot.
