Windev Mobile 17 - 1 Window Multiple Planes

Hallo

I have an Android App. I make use of 1 window with 5 planes.

Question 1

I don't know how to prevent my app from closing when the back/return button is pressed on the phone. If I am on plane 5 and press back my application returns to plane 1, the login plane
.

Question 2

If I am on, let's say plane 5, and tilt the phone sideways it also returns to plane 1.

The initialization code of my window just changes the plane to either 1 or the current plane.

Any ideas will be much appreciated.

In WD (not mobile) you can change the visible planes by windowname..plane = x, where x is number of the plane.

To go back from plane 5: If win..plane = 5 then win..plane = 4 and so on

Thanks Markus

It help a bit but my problem is the back button on the phone. I cannot trap the push event of that button.

If I have a back arrow on my window it works as you explained.

The back button in a mobile window works like the RedX in a window.

To overcome this you need to put a condition in the 'Window Closing' code section

IF MyWindow..Plane > 1 THEN
//Your condition here
END

You will need to know which plane you want the window to return to of course - depends on your app.
If its a simple scroll back the MyWindow..pane -= 1 will do if not you will need to program the sequence required.

Back buttons and App Close buttons are not recommended (allowed) in mobile apps.


Not sure about Q2 - the above may solve it but if not then there is a 'Change of orientation' code section available

Ericus,
on a tablet the Closing-event of the window is fired.
Using returntocapture() prevents the window (and thus your app) from closing.
But I can't say if this is the same on a phone.

Thanks Arie/Derek

Half my problem is solved but not the main one where the application is closed when back is pressed.

I used a returntocapture and it works correctly in Project test but not on the phone where it still closes.

Waiting to see if WinDev support can add anything.
