1.where to find some introduction to Chromium1RenderCompMsg? Thank you!

2. How to rightly operate new window in the Chromium1BeforePopup procedure.
sometimes, only using targetUrl is not enough to open new window using self defined form.

Thank you very much!

That event was added to intercept Windows messages sent to the browser. The MiniBrowser demo uses it to get the mouse coordinates.

2. How to rightly operate new window in the Chromium1BeforePopup procedure.
sometimes, only using targetUrl is not enough to open new window using self defined form.

The PopupBrowser and PopupBrowser2 demos show how to create popup windows using that event in OSR mode and normal mode respectively.
Read the code comments for more details.

Thank you for your help!

Is Chromium1AfterCreated procedure use a different thread?

If I create a tabsheet in this procedure I found that its thread ID is different from form. (use microsoft spy++)

In normal circumstances, most of the TChromium and GlobalCEFApp events are executed in CEF threads, different than the main application thread.

I simplified the code in the demos to make them a little easier to understand but you should never modify, create or destroy any VCL or FMX control inside those events.

Can browser be used as the follows in the Chromium1BeforePopup procedure ?
SendMessage(Handle, MINIBROWSER_DOCKWIN_MESSAGE, 1,Integer(@browser) );
or a record contains browser?
SendMessage(Handle, MINIBROWSER_DOCKWIN_MESSAGE, 1,Integer(@arecord ) );

I've never done that with a browser but I would try to do what Chromium expects us to do to avoid crashes.
