QT 4 qlabel how to work them

Ok last time I programmed was with Delphi 3 visual pascal.

I do know some C, C++

now I am using QT 4.72 QT GUI widget. Since I cannot get a GUI working in designer.

Still new, very knew.

here is the problem.

I added a qlabel called it "LStr" means Stregth.

Now I made a button call Roll AGain. and made a goto on it for the click.

I want to change the LStr test to say "18" or what ever I roll for it.

I tried LStr.SetText("18");
and
LStr->SetText("18");

but the program does not know what LStr is. ]

Should the editor (QT) know what your labels are and there names.

It was easy in Delphi but bit more confusion here.

Once I see how this is done, should be easier for me to get into the swing of things.

I hope

Thanks for all the help in advanced.

Tried to find a book but no lock here in small town of Cornwall, Ontario.

You can show some code, and i didn't understood if you used the designer or not, so if you created LStr in Designer, then in C++ code you will access it through ui, something like: ui.LStr->setText(...) (in case ui is an object) or ui->LStr->setText(...) (in case ui is a pointer)

the ui-> worked

Sorry I tried to use a QT console application but had to use a QT GUI widget because I could get get a frame/panel gui interface to setup in QT console application.

like I said just learning and can not find any good tutorials on basic programing in this environment.

The official tutorials look good, take a look here

Also this page deserves be bookmarked, since it contains articles on some Qt topics, like signals and slots, model view, etc.

Also the Qt documentation website is very good.
