Change imageloading in runtime

[thefunkyjoint]

Hi,

I use DCEF3 (https://github.com/hgourvest/dcef3), a component that enable Delphi programmers to use CEF library.

It has an option to enable or disable loading images. It works as it's set on design time. But when i change this in runtime, nothing happens.

Is this a limitation of CEF or a bug on DCEF3 ?

Thanks !

It is good to specify cross-links when you create cross-posts (you already ask this on stackoverflow.) Some active members follow this forum and SO too. http://stackoverflow.com/questions/37265472/delphi-tchromium-how-to-toggle-between-show-and-hide-images-with-options-image

It's good to have a second opinion, no ?

It is just my opinion. All my comments on SO. Without link followers doesn't have chance to find answer, in case if there your question is remains unanswered here. And at same time SO followers can't easily ignore same question.

Firstly always cross link your posts, no room for discussion there!

You can load a webpage with `webkit.webprefs.loads_images_automatically` set to false then later change it to true and the images will load (you cannot unload images once they're loaded).

You'd need a newish branch of `CEF` though, at least `2526`.

Quick test shows I can load google without images, invoke a button that changes the preference and images load.

This method must be called on the browser process UI thread.

For anyone interested in this method, this is very important that SetPreference is run on the correct thread.

Thanks, great point. Actually my workflow has some similarities with topic starter. But i'm ignore not only images, but also any media resources (i.e. also css). May be will try later to optimize logic.
