Problems with the Q_OBJECT-Macro

[spirit]

what the strange code

...
QtExplorer w = new QtExplorer;
w.show();
...

...
QtExplorer w = new QtExplorer;
w.show();
...

To copy to clipboard, switch view to plain text mode 

modify it

...
QtExplorer w;
w.show();
...

...
QtExplorer w;
w.show();
...

To copy to clipboard, switch view to plain text mode

Thanks now it works. But what is the difference? Why I cannot call it by the usual methode?

QtExplorer *w = new QtExplorer();
w->show();
delete w;

QtExplorer *w = new QtExplorer();
w->show();
delete w;

To copy to clipboard, switch view to plain text mode 

or

QtExplorer w;
w.show();

QtExplorer w;
w.show();

To copy to clipboard, switch view to plain text mode 

Once you create the object on the heap, once on the stack.

QtExplorer w = new QtExplorer();

QtExplorer w = new QtExplorer();

To copy to clipboard, switch view to plain text mode 

is just invalid code...

Okay thank you.
The reason why I changed it to a new()-constructor is, that I cannot debug the small program. If I start the debugger (under Eclipse Qt-integration, Linux) I get the message "No symbol "new" in current context." on the eclipse-console. I thought this isn't serious but I tied with a new()-operator.
I start debugging with the main-method (obvious) but if I jump to the construction point ( QtExplorer w; ) the sourcecode-window is closed with a message "No source available for "" " and if I go one step further, the whole execution stops with the message "Cannot find bounds of current function".

What is the meaning of that? (I installed the libqt-dbg!)

Thank you in advance

Ahhh, Im one step further.
But now gdb on eclipse stucks with the message:

Can't find a source file at "widgets/qlineedit.h"
Locate the file or edit the source lookup path to include its location.

So where should this source-code installed? I thought I have it all with the qt4-dev-package of debian?

Thank you

a) did you use #include <QLineEdit>?
b) Look, if under project->properties->C++ Include paths the right directories are set.
