Your English is good enough to communicate. Just a little hint among non-native English-speakers: the first letter of each sentence, the word "I" and the first letter of names (including the names of languages and countries) needs to be upper case -- this is not important to understand you, but it shows that you care about the one you ask. > i just want to a favor , and i haven't thouht it could cause your > worries. sorry every one. Exactly here lies the problem. We are all in the same situation as you are: we are just users of Qt and we all have problems that need to be solved fast. We are here to help each other out a bit. We are not here to patiently wait until someone comes with a little problem to be solved so we finally have something to break our boredom. And we are definitely not here to find out what the problem is in the first place. We do not just do favors, we expect you to make them as small favors as possible, because we have time for small ones, but not for big ones. Since this is a free day in Germany I'll do you a big favor by telling you how to get us to help you. So how do you get us to help you? Very easy. 1) Describe in a few short and precise sentences what exactly your problem is. -> Your mail did not meet this criteria because you did not describe what you expected and what we should look at. We had to guess. 2) Help yourself. Compile your own code, use your own code, check what it does on your own computer. Then describe it: what did you expect, what did you see instead, what do you want changed, and what do you not understand about this. 3) Use other tools to help yourself first: Trolltech has a list archive. Many questions have been asked before and can be answered by just looking into the archive. There are other forums out there and most are indexed by Google, Yahoo, and all the other search engines. Use those engines. Document that you have searched (eg. "I fed '+Qt widget problem' into Google, but did not get a useful answer"). 4) If possible provide minimal compilable examples. This means: a very short (max. 100 lines) piece of code that can be compiled without modification. -> Your code did not meet the second criteria: it was not compilable. 5) Use meaningful subject lines. "need your help" is not meaningful. It forces every one of us to read the mail first before we can decide whether we can help you. Use a line like "problem with layouts and widgets". There is more in the link I sent you, but I hope you get the point: we do not yet know what your exact problem is, you did not show that you tried to solve it yourself, we still do not have a compilable example that would actually help us to help you.
