    I have already an example QT application which I have modified.
    I have used a label object from the QT C++ Widget Box for which I want to set the text in my program.

    My code snippet:
    backLightStatusLabel->setText((di->backLightOn() ? "On" : "Off"));

    However, the compiler does not recognize the object(backLightStatusLabel - which I have already added on the application UI) and returns error.

    Is there something else that I need to do?

      Hi anobika, what's the compiler error?

      Is backLightStatusLabel in a .ui file?

      Tip: use @ around your code snippets to format it properly
      Tip2: Qt, not QT :-)

        Hi Anselmo,

        the compilation error is: backLightStatusLabel is not defined.
        The label is in a .ui file.

        1. I have updated the .pro file which previously had a different .ui file assigned to FORM parameter.
        2. Did a qmake
        3. built the code using the command make release-armv5

        I don't see a new u_*.h file getting created.

        Is there a separate command to build changes in the .ui file?

        Thanks for the tips :)

          Try calling 'make clean' and then 'qmake, followed by 'make ...' (whichever platform you are building for).

            Have tried it but that has not helped.
            Is there a need to use the uic Tool in this case?
            I am working on the S60 platform as mentioned. Please let me know the steps to compile the changes made in the .ui file.

              Have you tried something like

              ui.setupUi(this);
              ui.backLightStatusLabel->setText((di->backLightOn() ? “On” : “Off”));

                Hi there, sorry about the late answer, I did not have the expected Internet access while traveling. Well, QtK pointed well, you need to access the content of the class generated based on you .ui file - often a ui pointer declared in the header file of the class you're implementing (QtCreator does it automatically for you, I don't know if it is your case)
