Hello everyone!

I was wondering if there is a way to get the current X,Y pixel values when you press anywhere on the screen. Im running on a MTP2200 unified.

Hi,

It is possible to do it by scripting. Now I can't find the exact example where it is explained.

Hi,

Just a curiosity: what do you intend to do with this information?

 Been looking for this function as well, basically to drag an image to wherever the user would like to. (obtain pressed X, Y and move image to there). 

Hi Pegaia!

I am wondering if I can make a function where I can press on an object and drag it around the screen.

Hi gvatte,

There is a way to get the mouse events indirectly through a dynamic svg, attached is a rough proof of concept. By rough I mean I just knocked it together and it does 'stuff' but it is far from polished or ready for production.

A few comments and issues that I ran into:

• I can't seem to read the ParamProps outside of the control even though they are marked as 'two-way'
• HmiProps works but means you need to use the svg control as a proxy for another control to follow. That has to be done in TIA Portal using a cyclical property script or with a onPropertyChanged script
• There are air space issues with the svg control sitting in front of what ever you want to drag. This can be alleviated I think by using a transparent background and borders and then changing them with the internal MouseHover field. You can also set 'pointer-events' on individual elements of the svg if that helps.

If anyone is interested in how I figured this out, here are some places to start:

• Load the WebRH templates folder into VS Code and search for examples of how events and actions are used:
  • C:\Program Files\Siemens\Automation\WinCCUnified\WebRH\public\templates
    
  • Try
    • 'EventArgs' and 'HmiEventTrigger'
    • 'hmi-event:' and 'hmi:action'
• Open up the WebRTPU debug source code and look at what event types and args are available
  • C:\Program Files\Siemens\Automation\WinCCUnified\WebRH\public\libs\webrtpu.bundle.debug.js
  • Look at:
  • Line 7369 for the 'DefaultEventTransformer' which lists the event args
  • Line 7434 for the 'DefaultEventRegistration' which lists the event types

If anyone wants to take this further or has some ideas on how to turn this into a viable drag and drop solution without using a custom web control, I'd be keen to see the result.

A quick follow up, here is video of it working with a translucent background for debug purposes.

Old thread but just in case you are interested I was able to find a workaround and get the X Y coordinates back to Runtime.

Your MoveArea is the proof that it's possible to influence some attributes at least as it can modify the Top and Left parameters. So we can simply repurpuse the rotation pivot points, and we just have to monitor RotationCenterX and RotationCenterY parameters of the SVG objects.

I modified your MoveArea and attached it. Just drop it to a screen then you can monitor the X Y coordinates with IO fields using
