NavigationPane error crash on Q10 Simulator

Hi every body, I have a problem with NavigationPane on Q10 simulator.

 

This is my code:

 

        fprintf(stderr,"1-----------------------------------\n");


        Page* topPage = (Page*)navigationPane->top();


        fprintf(stderr,"2-----------------------------------\n");

 

navigationPane is not NULL Pointer and hold some page. It crash on 2nd line code.

On Z10 Simulator it is OK, but on Q10 Simulator it crash? Did I make some mistake or is it a bug?

 

Thanks for any reply!!!

Are you entirely sure that navigationPane is initialized? You might be running a section of code for the Z10 but most likely it's not running for the Q10.

 

Also, you don't need to cast the return value of top() to (Page*) because it's already returning a Page*...

 

--Edit--

For example, you might be running code which initializes navigationPane to something if the hardware doesn't have a physical keyboard..
