Need to access CurrentScreen

[oliverb]

I've just translated a project from Basic to C.
In the process I've lost access to the "CurrentScreen" variable. I've fixed it for now using an "extern", but I think this variable should be "exported" by default.

Hi Oliver,

Could you please provide us with more details about this issue?
Where have you defined the CurrentScreen structure? It should be defined in driver.c file.

Kind regards,

It should be defined in driver.c file.

That's the point, in a mikrobasic project it is in the "interface" part of driver.mbas, so it is available.
In a mikroC project it is in the "c" file, so effectively it is private to that file unless exported by a header.
The exports appear to be in <project>_objects.h

Hi Oliver,

There is an objects.h file in the mikroC VTFT project. There you can declare this object with an extern specifier to be able to use it in other source files.

Code: Select all

extern TScreen* CurrentScreen;

Kind regards,
