[Qt-interest] How to handle error

[Malyushytsky, Alex]

connect  retuns a value which you can check.
I usually do it for debug only:

bool ok = connect(......); Q_ASSERT( ok);

Subject: [Qt-interest] How to handle error

Hi all,

I don't think any class in Qt which tell the reason why error is appeared.

Some time we do mistake in  writing the programmes, some programme run with error only, it's pretty tough to identify the cause for error in Debugging the code.

For example in connecting the SIGNAL of one class to SLOT of another  need to have many conditions like, class object should be meta object,
parameters should be same. even if we do small mistake also programme will compile, but signal slot will not work.

Like this there may be verity of problems.

Is there any class which popup error number, using that we can identify easily the cause for problem. Is there any such mechanism in Qt?
