Hi All,
I'm the author of this thread. Because I didn't receive the confirmation
mail using 126.com mailbox, I changed to gmail mailbox.
Seems the ::MessageBox comfused us, ok, forget it please.
I found the issue when a destructor of a local static object wasn't called
when my first Qt program exiting after calling QMessageBox::warning(). If I
didn't called QMessageBox::warning(), the destructor was called normally.
I modified the demo program. explain it here.
1. Create a “Qt Application” project (named QtTest) in VS2010 by Qt
Add-in with default settings.
2. Add an action, and call QMessageBox::warning() in its slots.
3. Create another DLL project (named MyDll) in VS2010, with a single
export function (named foo).
class MyObj
{
public:
~MyObj() {
printf("destructor called.\n");
}
void test() {
printf("test() called\n");
}
};
void foo()
{
static MyObj obj;
obj.test();
}
4. Call the exported function “foo()” in QtTest project.
QtTest::QtTest(QWidget *parent, Qt::WFlags flags)
: QMainWindow(parent, flags)
{
ui.setupUi(this);
// foo is exported in MyDll.dll, to make sure MyDll.dll is loaded
foo();
}
5.
