hi dj, did you load the Qt documentation from the cd? I couldn't have gote by without it, the online version http://doc.trolltech.com/4.1/index.html
heres to QLabels: http://doc.trolltech.com/4.1/qlabel.html

also when in Qide once you've created your object and you put a . after it , it should show you all the available functions for that object type eg :

usernameLabel = new QLabel(tr("Username:"winking smiley);
usernameEdit = new QLineEdit;
usernameLabel.


now you should get a dropdown with backgroundColor as an available function..( your cursor must be just after the dot, if it isn't remove the dot and type it again then wait)

funny enough i wasn't able to find this function in the class library although its probably a function in one of the inherited classes further up the line

hope that helps . PS sorry i didn't et back to you about the other problem i just haven't had enough time

thanx for the light iva, yes dropdown shows the list of all available members for the QLabel including the setbackgroundColor but it still gives an error : not member function setbackgroundColor exist for class QLabel. or maybe we are not using the paramenters correctly.

Anyway i'll keep on tackling this problem. good luck with your exams.
