How can i destroy the browser after create ?

Code: Select all

chromium:=Tchromium.Create(nil);
chromium.DefaultUrl:=url;
if not chromium.Initialized then Chromium.CreateBrowser(nil, '');
while True do begin
if (chromium.Initialized) then Break;
Application.ProcessMessages();
end;
chromium.LoadURL(url);

Code: Select all

chromium.Destroy //NOT WORK
chomium.free //NOT WORK
chromium.CloseBrowser(true); //NOT WORK
Freeandnil(chromium); //NOT WORK
chrom.CloseAllBrowsers; //NOT WORK

And all together does not work either

Use the code in one of the demos as a template for your application.
CEF and Chromium require creating and destroying the browsers following certain steps that are described and implemented in the demos.

Read this document :

Use the code in the SimpleBrowser2 demo in case your application uses VCL.

Avoid using Application.ProcessMessages and waiting loops because they only cause problems with CEF.

Well, how is the result? *

[Uefi1]

Ok from the example

Code: Select all

PostMessage(Handle, CEF_DESTROY, 0, 0); // NOT WORK 

How can I destroy this ebon browser?

Make sure your application has all the code from the demo that you decided to use as a template.
If CEF_DESTROY doesn't work it means that some code wasn't copied to your app.

NOW i am using code this, Destruction doesn't work help what's wrong then ??????

Code: Select all

var
chrom:Tchromium;
aAction : TCefCloseBrowserAction;
begin
chrom:=Tchromium.Create(nil);
chrom.OnBeforeResourceLoad:=Chromium1BeforeResourceLoad;
chrom.OnLoadingStateChange:=Chromium1LoadingStateChange;
chrom.DefaultUrl:=url;
if not chrom.Initialized then Chrom.CreateBrowser(nil,'');
while True do begin
if (chrom.Initialized) then Break;
Application.ProcessMessages();
end;
chrom.Browser.MainFrame.GetSourceProc(StringVisitor);
end;
aAction := cbaDelay;
PostMessage(Handle, WM_CLOSE, 0, 0);
PostMessage(handle, CEF_DESTROY, 0, 0);

That's not the destruction sequence described in the demos. Please, read my previous comments in this thread.

Ok, I still don't know how to close and release the dynamically created browser.
I'm waiting for a decision from you

My previous answer is still the right one :

Use the code in the SimpleBrowser2 demo in case your application uses VCL.

Avoid using Application.ProcessMessages and waiting loops because they only cause problems with CEF.

If you need to create and destroy multiple browsers in your application you should use the code TabbedBrowser2, ToolBoxBrowser or MDIBrowser demos.

Use any of those demos as the foundation for your application and build the rest on top of that code.
