Hi guys,
I already searched in docs and community but only found one likely similar topic.
I want to link from a button to another page in the app and if possible pass a percentage value for the web viewer component. The reason is that a web application is to be loaded that has a higher resolution than the device. Is this possible or do I have to call external browser directly? Can I specify the value for external browser?
Thanks in advance
Daniel

If you add a Web Viewer to a screen and click on it in the Blocks tab, you can see the values you can change using blocks:
To “pass” a value from one screen to another, store it in a variable.

Thanks you for your reply. But this does not really answer my question. Is it generally possible to pass a value for resizing the display from 100% to 75% for example?
I am new to these functions and i am even struggling to find the right function. To pass a value from one screen to another, in my example I have to add the value stored in a variable to the button which links to the new page with the web viewer, right?
How do I add a variable to a button to pass it over? Which block do i have to use?
Sorry, but this is really difficult to me…
Thanks in advance.

I don’t know if it’s possible to zoom the Web Viewer. I don’t think it is. But as I said, if you did have a way, you can reference values set on one screen on another screen using variables.
