How to use AdditionalBrowserArguments correctly

[sane-git]

Hello dear WebView2-Team and community.

I'm trying to apply the RTL reading mode for my WebView2 MFC application.
Of course I could add dir=rtl attribute to the html tag.

But I'd rather go with some chromium flags specifically added for this purpose. These flags are:

• force-ui-direction=rtl and
• force-text-direction=rtl

I tried to add these as additional browser arguments like so (C++ code)

CComPtr<ICoreWebView2EnvironmentOptions> pOptions;
CCoTaskMemString AdditionalArguments;

pOptions->get_AdditionalBrowserArguments(AdditionalArguments);

if (AdditionalArguments.Length() > 0)
	AdditionalArguments += OLESTR(" "); // Separate existing arguments by <VK_SPACE>

AdditionalArguments += OLESTR("--force-ui-direction=rtl --force-text-direction=rtl");

pOptions->put_AdditionalBrowserArguments(AdditionalArguments);

Unfortunatly this is doesn't change a thing. Using colon instand of equal sign doesn't help either.
Is this approach (Options.AdditionalBrowserArguments) the correct way to achive RTL direction?
Or am I doing something wrong?

Many thanks for looking into this.

Best regards,
Sascha

Hello dear WebView2-Team and community.

I'm still wondering on how to pass the chromium flags

• force-ui-direction=rtl and
• force-text-direction=rtl

as additional browser arguments to the WebView2 control.

Any idea?

Best regards,
Sascha
