Compilation errors with example UI application on S60 platform

[anobika]

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)
