[Qt-interest] QLineEdit press enter key

[Tony Rietwyk]

Hi Ken, 
 
Your subject has nothing to do with your question!  Try 'QTreeWidget does
not update after being cleared'.  
 
We have this problem with all of the item view widgets on Mac OSX 10.5 with
Qt 4.6.0.  I think the problem is the underlying QScrollArea.  
 
Our current workaround is to add: 
 
if (ui.treewidget->viewport() != NULL)
      ui.treewidget->viewport()->update();

after the list/table/tree is updated. 
 
Hope that helps,
 
Tony

    ui->selJobTreeWidget->clear();
    int filterCount=0;
    for(int i=0;i<jobNameList.count();i++)
    {
        if (jobRegExp.exactMatch(jobNameList[i]) &&
dbRegExp.exactMatch(dbList[i]))
        {
            item = new QTreeWidgetItem(ui->selJobTreeWidget);
            item->setText(0,jobNameList[i]);
            item->setText(1,dbList[i]);
            filterCount++;
        }
    }
    QString jobHeader = QString("Job Name(%1)").arg(filterCount);
    ui->selJobTreeWidget->setHeaderLabels(QStringList() << jobHeader <<
"Database");
}
 
void selJobWindow::on_selJobJobName_returnPressed()
{
    filterJob();

}
