How to control this page when opening a new page window
TChromium has a OnBeforePopup event where you can block or allow popups.
That event is now called in the UI thread and it should be easier to add your own form with a TChromium instead of letting CEF3 create a new window for you.
The /include/capi/cef_life_span_handler_capi.h file in the CEF3 sources have these comments about that event :
Code: Select all
///
// Called on the UI thread before a new popup browser is created. The
// |browser| and |frame| values represent the source of the popup request. The
// |target_url| and |target_frame_name| values indicate where the popup
// browser should navigate and may be NULL if not specified with the request.
// The |target_disposition| value indicates where the user intended to open
// the popup (e.g. current tab, new tab, etc). The |user_gesture| value will
// be true (1) if the popup was opened via explicit user gesture (e.g.
// clicking a link) or false (0) if the popup opened automatically (e.g. via
// the DomContentLoaded event). The |popupFeatures| structure contains
// additional information about the requested popup window. To allow creation
// of the popup browser optionally modify |windowInfo|, |client|, |settings|
// and |no_javascript_access| and return false (0). To cancel creation of the
// popup browser return true (1). The |client| and |settings| values will
// default to the source browser's values. If the |no_javascript_access| value
// is set to false (0) the new browser will not be scriptable and may not be
// hosted in the same renderer process as the source browser. Any
// modifications to |windowInfo| will be ignored if the parent browser is
// wrapped in a cef_browser_view_t. Popup browser creation will be canceled if
// the parent browser is destroyed before the popup browser creation completes
// (indicated by a call to OnAfterCreated for the popup browser).
