Webview: adding links to other graphics screens

[controls.02]

Hi All,
I’m trying out the Webview inside the T3000 software. However, I’m having some trouble with the changing graphics screen function. My current setup is I have two graphics screen, 1 and 2. In the first screen, I have an arrow icon that is linked to the second screen.

However, when I click on the arrow, the screen is not change to the 2nd graphics, and the T3000 software display an error message “Panel is invalid or index is invalid”. The T3-TB device panel number is set to 1.

I have updated the app to the latest version of Jul 15, 2025.
If you need anymore information, please tell me.
Because this is an important feature, please help me resolve this problem as soon as possible. Thank you.

Hi, good day.

Could you please share all the files under the \T3000\ResourceFile\webview folder? We want to perform a simulation in your environment.

And its also directly available here:

Hi, any updates on this topic? Using the compiled T3000 software or building from source still result in “Panel is invalid” error. Can you reproduce this error on your side?

A valid panel number should be between 1 and 254. Could you provide more details? What device did you select? Which object did you link? More detailed operation steps will make it easier to find the root cause of the problem.

Thank you for replying.
What I’m doing is very simple. To summarize:

• I have 2 graphics:
  
  
• In Graphic 2, I have a picture
  
  
• In Graphic 1, I put an arrow icon. Then link the icon to Graphic 2.
  
  
  
  
  
• Press the lock icon in Graphic 1, then click the arrow icon. I get the message “Panel is invalid or index is invalid”, and it doesn’t move to Graphic 2.
  
• Device panel number is set to 1
  
  
• I’m using T3-TB.
  If you need any other details, please let me know.
