Delphi TChromium : how to toggle between show and hide images with Options.ImageLoading

Question

I'm using TChromium to navigate to pages. It has the property Options.ImageLoading , where you can specify if you want to show website's images or not.

Problem is it works only with the option is set in design time. If i change this property in runtime, it has no effect. Here is an example code ; what i wanted to achieve in this example was open test1.com showing images and open test2.com hiding images. Unfortunately both sites are loaded with images, ignoring the option i set.

Any ideas how to fix this ? I want to be able to show images only for certain websites.

procedure tform1.button1click(Sender : TObject);
begin
chromium1.options.ImageLoading = STATE_ENABLED;
chromium1.load('www.test1.com');
end;

procedure tform1.button2click(Sender: TObject);
begin
chromium1.options.ImageLoading = STATE_DISABLED;
chromium1.load('www.test2.com');
end;

Answer 1

Because @delphirules actually ask about deffered image loading, and next answer is greatest (and applicable to any chromium-based solution) i'm re-post part of this answer here:

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

Thanks to user amaitland for great findings. :)

Answer 2

Try this:

• Create two instances of TChromium, one with options.ImageLoading := STATE_ENABLED and the other with options.ImageLoading := STATE_DISABLED

• Then, when you want a page to be loaded, make the first one visible and the other one not visible and vice versa.

Obviously, there may be a bit more to do than that, but at least it would avoid having to recreate the browser each time you want to change.
