General and Desktop

I compiled the Qt4.8 from sources with dbus disabled and now it's working....well, not 100% yet. but I'll open another topic because it's other problem.

Hi, I need a little help with my code. I am trying to put scrollbars on my code. It is a form that i would like to be in a groupbox and the groupbox in a qvboxlayout. @ QVBoxLayout* _layout3; QFormLayout* layout; QScrollArea *scrollArea = new QScrollArea(this); scrollArea->setWidgetResizable(true); QGroupBox *groupBox = new QGroupBox(scrollArea); QWidget *baseArea = new QWidget(); baseArea->setLayout(_layout3); scrollArea->setWidget(baseArea); while(!patients3.isEmpty()) { QMap<QString,QString> patient = patients3.takeFirst(); if (patient["id"]==itemId) { QLineEdit *MyLineEdit = new QLineEdit(patient["id"]); layout->addRow("ID",MyLineEdit); layout->addRow("Surname", new QLineEdit(patient["surname"])); layout->addRow("Name", new QLineEdit(patient["name"])); } groupBox->setLayout(layout); scrollArea->widget()->setLayout(_layout3); this->_layout3->addWidget(groupBox); }@

[quote author="Tobias Hunger" date="1328605587"]qt_metacall just shows that it was triggered via a signal/slot connection. You will need to dig deeper.[/quote] OK ... this is call stack: !http://s2.picofile.com/file/7285959886/snapshot12.png(Call stack)!

yes: [quote author="Franzk" date="1328548005"]The sanest way to work around this I think is to wrap the C++ dll in a C interface dll (using msvc express). Then you can use gcc to (dynamically) link against that. C linkage is defined, unlike C++. It's usually the easiest if the vendor doesn't supply mingw builds (like Qt does).[/quote] this was my first solution, then I got enough budget to re-implement the stuff, so everything now is MSVC... because of the difference between GCC and MSVC, there is no other way then to warp the DLL (many tutorials on the web on this). or go MSVC/GCC all the way.

This is, what I expected. Thank you. As the program shall be used by other people, I cannot force them, to use SSD. But this shall be their problem :-p

Thanks, that worked

999 returns the Intermediate state, you still can make that number acceptable by inserting a decimal point somewhere.

Thanks Paul! Although, excuse my ignorance, but I have to ask, is this something Wacom should implement on their drivers, or is it something users can apply somewhere?

Hello If the forum I saw many problems using QSqlTableModel in queries, using setFilter () sql limiting, a comparison of the method QsqlQueryModel setQuery () solve this problem, but not well integrated QSqlQueryModel to sort data in QTableView sortingEnabled to order the sql query (producModel-> QSqlQueryModel :: setQuery (QString ("Select * From product where (product.id =% 1) limit 200"). arg (id)) ;) vanishes, well this is just some , what would be the best option Management System For Cars (desktop). -With a large amount of data (200000 users). -DB-Connection (Postgres). -Ease of use.

Marked as resolved. See here: http://developer.qt.nokia.com/forums/viewthread/6725

Do not use C++11 with MinGW 4.4. It just doesn't work in most cases. Get an up to date version of MinGW or get MSVC2010 - both at no cost.

What file not found is Empty

Got it: wrote a make function makro and added it to the .pro file Write this in your .pro file: @ #without this variable qmake generats "" in the makefile e.g.: ..patsubst\ ./... MY_VARIABLE = patsubst LIBS += $($$MY_VARIABLE %.so,%,$(subst /path/to/libsfolder/lib, -l, $(wildcard /path/to/libsfolder/*.so))) @

I merged the separate topics as both contained the same question, and moved it from the Qt Quick to General and Desktop as it was unrelated to QML/Quick.

Now it works. I tried something like that earlier and it didn't work, but now I know what I made wrong. Thank you.
