Realtime Swipe and Press Gestures and Dual-state buttons

[marcelerkel]

Great work on the gesture detection!

When using dual-state buttons, the Nextion firmware immediately changes the state of the button on touch. So if you start a gesture on a dual-state button then the button has an incorrect state after the gesture is detected. I fixed this by adding the following code to invert the state of the button again when a gesture is detected:

    if(b[tc0.val].type==53) // Swipe triggered, restore dual-state button state
    {
      b[tc0.val].val=b[tc0.val].val^1
    }

These few lines of code are added to the Timer Event code in the following location:

  //
  // Movement > 100px => SWIPE
  if(dsq>10000)
  {
    if(b[tc0.val].type==53) // Swipe triggered, restore dual state button state
    {
      b[tc0.val].val=b[tc0.val].val^1
    }
    if(dx>100)
    {
      //>>
      gest_type=1 // right
      //page 0  // <- CUSTOM*** live action here
      //      t1.txt=">>" // ***DEGBUG/DEMO
    }else if(dx<-100)

Normally I would have created a PR, but unfortunately HMI files are binary files. Instead of updating the Tips_and_Tricks.HMI file I thought it would be better to just create an issue with the solution.

Thanks for the tip. I'll test this out and look at adding it when I next get a chance to update the project.
