We have to use the virtual Keyboard in 12 screens in our application.Hence we want to make it as a common component that will be used across the screens.We created the keyboard screen using QT Creator 4.5.3.We are also able to add the keyboard in different projects in our application. But we strucked in the midway, because all the button action events are handled in the particular keyboard file. How we can intimate the keys pressed in the keyboard file to other projects which are using the keyboard?

Example: We are havine Line Edit widget in one screen and in the same screen, we are adding this keyboard component which will be in the another project. While we press the keys in the keyboard, the corresponding data should reflect/display in the Line Edit field of the screen.

Can anybody please help on this issue?
