Hello Community,

I am trying to display a Webpage in a WebView inside of my form. This Webview is part of my UI and has the full height and ca. 10% of the width of my form.

Im loading a page thats content is set to have 100vw / 100vh size. But the WebView doesnt seem to be able to interpret the relative sizing style options. If I set absolute px Values, the Websites content is rendered correct but with relative values viewport/%, only a part of the Website is visible.

Is there any workaround for this issue?

Im not using the pixel values because my form is resizable.

Thanks for your help @alwaysbusy, but unfortunately its still not working.

@Erel Most of my layout is created with the designer but the webview is created at runtime based on an .ini file.

But I dont understand why WebView has this issue, WebKit seems to support it. Is this a known issue?

You are the first to report it. B4J WebView is a thin wrapper above JavaFX WebView. You can search Google for JavaFX WebView and this issue. I haven't found anything related.

Most of my layout is created with the designer but the webview is created at runtime based on an .ini file.
Unless it comes directly from a html string then it will be simpler to build the views programmatically.

Thanks @Erel for your help. I was wondering too about the fact that there is nearly nothing to find on goole about this.

But now ive tried a few things and found the solution (its pretty ridiculous)

My WebViews Height was set to have its Parents PrefHeight and this was set to -1. So I think this was setting my WebView to resize to the size of its HTML content.
