How to change to the previous screen

[Hwoo-]

Hi,

I want to do something like this:

1) receive button input from touchGFX

2) execute operations to be processed

3) switch to the previous screen or a specific screen.

​​

I run it as below, but the same screen appears.

void bookScreenOperView::operOKFunction()

{

  //report to presenter and update text

  presenter->userSetOperOK();

  bookScreenOperView::tearDownScreen();

}

​

How can I solve this problem ?

​

Best regards,​

Hi,

You can use touchgfx designer.Add a button,and then select "Change screen" for your expected screen.

If you want to do something between click button and change screen ,you should add new interaction which choose to execute C++ code.Remember to tick the box.And then add new interaction which use another interaction is done trigger to change screen.
