    <p>Always pick a title that draws in a programmer.</p> <p>Anyway I'm using linux and I compiled the qt4.7.1 libs using ./configure -static -nomake demos -nomake examples -nomake tools -prefix /local/qt/qtstatic</p> <p>the build and install all went fine, and I set it up in qt creator so I can build with it. Building any application works fine, however when I run the application it gives me an error.</p> <p>QWidget: Must construct a QApplication before a QPaintDevice Aborted</p> <p>I understand that this means a static object is trying to use a class (QPaintDevice) that needs QApplication to be called first, and since static objects are all processed before the actual application this is obviously going to fail, The first line after my main() is the QAplication, however I know that doesn’t make a difference, My .pro does contain CONFIGURE +=static, and I have defined static in the main program, Qt4 just doesn't like me.</p> <p>How can I fix it so the static objects don't all go insane like this.</p> <pre><code>#include &lt;QtGui/QApplication&gt; #include "microbrowse.h" int main(int argc, char *argv[]) { QApplication a(argc, argv); microbrowse w; w.show(); return a.exec(); } </code></pre> <p>is the main, but that's probably not important, the main is pretty much the same for all QT apps made by qt creator, except microbrowse is the name of whatever widget your working on. The widget microbrowse is the entire program, all this does is create the QApplication, and dimension microbrowse. </p>

    1. COCould you post your main(), it could be helpful.

    2. COAren't you suppose to declare microbrowse on stack? `microbrowse *w = new microbrowse(); w->show();`

    3. CO@Evan: Your code creates microbrowse on the heap, not the stack. But it shouldn't matter here -- the same constructor gets called, at the same time. The important thing is that microbrowse not be static. OP's code looks fine to me. I suspect the problem is in the _implementation_ of microbrowse.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
