Popup with return value

[CHech.1]

Hi,

I'd like to have a popup in my app, in which the user can press "Confirm" or "Cancel".

I'm looking for a way to have my code written like this:

popup_res = show_popup();
if(popup_res == true){
    /* user clicked on 'confirm'. do something */
}
else{
    /* user clicked on 'cancel'. do something else*/
}

Is there a way to do it?

I know that touchgfx is single threaded, so I think that I have to finish the function to refresh the screen.

But on the other hand, I know that GUI frameworks such as JavaFX are also single threaded, yet support this behaviour.

Thank you

Hello CHech.1,

The easiest way to have something like this would be to add some widgets to your screen (for a popup it would be like a box, 2 buttons, and a textArea), and play with them with the setVisible() function. If you want to use it in multiples screens, the best way would be to create a custom container that you'd call "popup" and use it in your screens. You can follow this tutorial if you begin with custom containers.

We did a something similar, with the addition of the option to provide callbacks when ok/cancel are clicked.

Ok cool if you have succeeded on it 🙂

By the way, just remembered, we actually have a example in TouchGFX Designer about popup, it's called "ModalWindow Example".
