I want to know the X and Y coordinates when the button is pressed

[Ebun.1]

Thank you for helping.

At the event of pressing the button of the view class

Is there a way to find out the touched X, Y coordinates?

Thank you.

Hello Ebun.1,

You simply need to implement the handleClickEvent() function in your view to receive the click events.

void Screen1View::handleClickEvent(const ClickEvent& evt)
{
    touchgfx_printf("Cooordinates of the click event : x = %d/ y = %d\n", evt.getX(), evt.getY());
    Screen1ViewBase::handleClickEvent(evt);
}

Hi Alexandre RENOUX

Thank you for helping.

I have an interaction when the button is pressed.

How can I get x and y in this?

Screen1View :: pushedButton ()

{

 // get x, y

}

Hi Ebun.1,

You cannot do that simply like this.

I would highly recommend you to use handleClickEvent() function and do something like :

void Screen1View::handleClickEvent(const ClickEvent& evt)
{
    if(button1.getAbsoluteRect().intersect(evt.getX(), evt.getY()))
    {
        if(evt.getType() == ClickEvent::PRESSED)
        {
            //retrieve x, y with evt.getX()/evt.getY()
            //Do whatever you want, you can even call other functions
        }
    }
    Screen1ViewBase::handleClickEvent(evt);
}

Hi Alexandre RENOUX

I am always grateful for your help.

It's not easy, isn't it?

Thank you for your answer.

Could you please explain your solution a little more clearly? I am having the same problem.

Hello.

I wanted to know the raw value before the coordinate transformation, so

I decided to save the coordinates in a global variable in BSP_TS_GetState () and use it.

The example looks to be pulling the X and Y coordinates at the event, then determining if those are within the boundaries of the button image on the screen, and then allowing you to take a specific action. If you want to remember the X,Y coordinates save them in a variable or class where you can get at them later, or pass them to a processing function.

Hey,

you can try this one too, hope it may works for you.

OnTouchListener mOnTouch = new OnTouchListener()

{
 
 @Override
 
 public boolean onTouch(View v, MotionEvent event)
 
 { 
 
 final int action = ev.getAction();
 
 switch (action & MotionEvent.ACTION_MASK) {
 
 case MotionEvent.ACTION_DOWN: {
 
 final int x = (int) ev.getX();
 
 final int y = (int) ev.getY();
 
 break;
 
 }
 
};
 

And if its works and you already got one please mention it too. Thanks.
