Hi, As I know, QAbstractTableModel is abstract So to use it we have to subclass it. When subclassing QAbstractTableModel, you must implement the three pure virtual methods : @ virtual int rowCount ( const QModelIndex & parent = QModelIndex() ) virtual int columnCount ( const QModelIndex & parent = QModelIndex() ) virtual QVariant data ( const QModelIndex & index, int role = Qt::DisplayRole ) @ They are pure virtual (const=0) so they have to be reimplemented !!!

Hi, There are 4 ready-made layouts : QVBoxLayout, QHBoxLayout, QGridLayout and QFormLayout. All of them inherit QLayout. If any of them doesn't fit your application you can subclass QLayout and create a custom layout :)

Hi, i know it is off topic for Qt forum, but try those: "http://sourceforge.net/projects/libcdrip/":http://sourceforge.net/projects/libcdrip/ "http://www.un4seen.com/":http://www.un4seen.com/

I see, it's not a problem if Qt, it's wrong mime data processing on Skype side. Along with "text/uri-list", Qt provides "UniformResourceLocatorW" value with the same data (i cant deny it, it is added a much deeper, than Qt user can get). And Skype processes both values - "text/uri-list" and "UniformResourceLocatorW", causing sending the same file twice.

Super Cool... It works fine. Thanks a lot... :)

Finally it works, I used srand() in Qt qsrand() and using the code: qsrand(time(NULL)); ID=qrand() % 6; qDebug << “ID random: “ << ID; Thanks for the idea srand().

Thank you for exellent links. I got it done. :) http://aijaa.com/cPWcy8

Some points stand out - line 2 shows 'base', whilst line 8 shows 'baseUrl', so you are dealing with different objects. Have you defined 'base' anywhere? .resolved must follow a Qurl object, but you have 'baseUrl', which presuming you mean 'base', is a QString. Try changing line 2 to: Qurl baseUrl("http://qt.digia.com"); Also, line 7 seems pointless. You take a QString, change it to a Qurl, then convert back! The scope of uu and rurl are only within the if statement, so you will not be able to use them later in your code. Since urlForReq is a QString, you will not be able to use it as a Qurl without converting it later. HTH

Be sure and edit your initial post and add [Solved] to the title. Thanks!

I see, thanks! By the way, I just noticed that QSharedMemory::setNativeKey will set the native, platform specific key for this shared memory object, that will also help in Qt code to connect to shared memory created from Windows code.

I found a solution. The problem is, that QTextDocumentLayout::draw takes a parameter QAbstractTextDocumentLayout::PaintContext ctx. This one is defined inside QTextDocument. Now I wrote a new drawContents function which takes an additional parameter QTextDocument. The example from above works with this additional function. @void drawContents(QTextDocument *td, QPainter *p, const QRectF &rect) { p->save(); QAbstractTextDocumentLayout::PaintContext ctx; ctx.palette.setColor(QPalette::Text, p->pen().color()); if (rect.isValid()) { p->setClipRect(rect); ctx.clip = rect; } td->documentLayout()->draw(p, ctx); p->restore(); }@

From the event you get the old size and the new size. You have to write a function f(winsize) which can calculate the size of your dock widgets which can be resized by using their resize method.

[quote author="beemaster" date="1351507667"]Have you tried "updateGeometry":http://doc.qt.digia.com/qt/qwidget.html#updateGeometry ?[/quote] Thanks for the tip, QWindow doesn't have updateGeometry().

Thanks Andre.... :)

Thanks Krzystof. That's exactly what i needed. Adding in the message handler this : @ case QtDebugMsg: std::cout << msg; break; @ gave me the behavior i was looking for.

yes I ran in debugger. After the function called it returned exited with code 1.

Many thank's, finally it works using QTextStream. :)
