General and Desktop

You're welcome. I typed one "k" to much. but it all stays in the same family ;)

If you declare a function in header & not implemented in source file, that can produce such similar error. you can check the "Compile Output" Tab to see what is needed...

You are welcome! Sorry again for my first proposition - I rushed to answer without having read the question carefully :)

But that's only needed on windows for MSVC compiler, mingw does it in another way, so I suggest using Q_DECL_EXPORT / Q_DECL_IMPORT. They map to the correct, compiler specific code.

as Tobias said, use "QString::number":http://doc.qt.nokia.com/4.7/qstring.html#number

@loladiro Just once ;) Man you're fast!

Use QWidget::open() for window modal behavior.

Okeh, thanks!

Found easy solution by using signals and slots. This system rocks! @// Populate the group ComboBox groupModel = new QSqlRelationalTableModel(this, QSqlDatabase::database("******")); groupModel->setTable(""TB_Groupe""); groupModel->setSort(groupModel->fieldIndex("GR_Nom"), Qt::AscendingOrder); groupModel->select(); ui->MW_groupComboBox->setModel(groupModel); ui->MW_groupComboBox->setModelColumn(groupModel->fieldIndex("GR_Nom")); // Populate category ComboBox according to Group ComboBox catModel = new QSqlRelationalTableModel(this, QSqlDatabase::database("*******")); catModel->setTable("\"TB_Categorie\""); catModel->setFilter("\"CAT_IndexGroupe\" = " % QString::number(ui->MW_groupComboBox->currentIndex()+1)); catModel->setSort(catModel->fieldIndex("CAT_Nom"), Qt::AscendingOrder); catModel->select(); ui->MW_catComboBox->setModel(catModel); ui->MW_catComboBox->setModelColumn(catModel->fieldIndex("CAT_Nom")); connect(ui->MW_groupComboBox, SIGNAL(currentIndexChanged(int)), this, SLOT(RefreshCategory(int))); } void MainWindow::RefreshCategory(int choice) { catModel->setFilter(""CAT_IndexGroupe" = " % QString::number(choice+1)); catModel->select(); ui->MW_catComboBox->setModel(catModel); ui->MW_catComboBox->setModelColumn(catModel->fieldIndex("CAT_Nom")); }@

Here are the results of the checks with Microsoft's Office Excel: one has to rename the file from .xlsx to .xml to be able to import it using a literal newline character ('\n') in the strings does not work replacing the literal newline with '
' (aka entity) does work one must put a suitable cell format into the xml to enable line breaks So, the conclusion is, that the XML parser that is used by Excel to handle the file is definitely broken and does not follow the standards! You can easily test this by using xmllint: Save a file from excel in XML format, have xmllint parse it and save the result (this replaces all '
' with literal newlines) and try to open the file in Excel. It will fail. Unfortunately I see no chance in getting some easy support for this case into Qt. You would have to patch method "static QString encodeText()" in qdom.cpp to escape newlines.

well, I solved it by using the painter: @ void MyTypeDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const { int value = index.model()->data(index, Qt::DisplayRole).toInt(); QString text; switch(value){ case MyTypes::Type_A: text = "type A"; break; //.... and so on }; QRect r = option.rect.adjusted(2, 2, -2, -2); painter->drawText(r.left(), r.top(), r.width(), r.height(), Qt::AlignVCenter|Qt::AlignLeft|Qt::TextWordWrap, text, &r); @ it is a quick and dirty solution but will do for the time table I have for this, a proxy model might be a better solution, but, the delegate also handles the editing part of the cell, so, it's a good 'all in one' solution

hello everyone i got success. thanks volker and andre , you really helped me.

I knew what you meant jim and now my problem seems to be fixed. I did the following: @node->setPos( (node->getXMax() - node->getXMin()) / 2.0 + node->getXMin(), (node->getYMax() - node->getYMin()) / 2.0 + node->getYMin() ); scene()->addItem( node );@ so the the item's center is half between xmin and xmax and half between ymin and ymax. The bounding rect is now implemented as follows: @QRectF MyGraphicsItem::boundingRect() const { QPointF pt1 = mapFromScene(QPointF(xmin,ymin)); QPointF pt2 = mapFromScene(QPointF(xmax,ymax)); return QRectF(pt1,pt2); }@ So the boundingRect() lies correctly around the center. The item's are now drawn correctly, even if only partly visible. Many thanks to everyone who helped me out of this! :)

Cheers Jim.

I doubt it can be done, at least in a straightforward way.

Thanks, it worked
