wx.html2.WebViewEvent¶

A navigation event holds information about events associated with wx.html2.WebView objects.

Events Emitted by this Class¶

Handlers bound for the following event types will receive a wx.html2.WebViewEvent parameter.

EVT_WEBVIEW_CREATED: Process a wxEVT_WEBVIEW_CREATED event, generated when the object is fully initialized. For the backends using asynchronous initialization, such as WebViewChromium , most of this class member functions can be only used once this event is received.
EVT_WEBVIEW_NAVIGATING: Process a wxEVT_WEBVIEW_NAVIGATING event, generated before trying to get a resource. This event may be vetoed to prevent navigating to this resource. Note that if the displayed HTML document has several frames, one such event will be generated per frame.
EVT_WEBVIEW_NAVIGATED: Process a wxEVT_WEBVIEW_NAVIGATED event generated after it was confirmed that a resource would be requested. This event may not be vetoed. Note that if the displayed HTML document has several frames, one such event will be generated per frame.
EVT_WEBVIEW_LOADED: Process a wxEVT_WEBVIEW_LOADED event generated when the document is fully loaded and displayed. Note that if the displayed HTML document has several frames, one such event will be generated per frame.
EVT_WEBVIEW_ERROR: Process a wxEVT_WEBVIEW_ERROR event generated when a navigation error occurs. The integer associated with this event will be a wx.html2.WebViewNavigationError item. The string associated with this event may contain a backend-specific more precise error message/code.
EVT_WEBVIEW_NEWWINDOW: Process a wxEVT_WEBVIEW_NEWWINDOW event, generated when a new window is created. You must handle this event if you want anything to happen, for example to load the page in a new window or tab. For usage details see wx.html2.WebViewWindowFeatures.
EVT_WEBVIEW_NEWWINDOW_FEATURES: Process a wxEVT_WEBVIEW_NEWWINDOW_FEATURES event, generated when window features are available for the new window. For usage details see wx.html2.WebViewWindowFeatures. only available in wxWidgets 3.3.0 or later.
EVT_WEBVIEW_WINDOW_CLOSE_REQUESTED: Process a wxEVT_WEBVIEW_WINDOW_CLOSE_REQUESTED event, generated when a window is requested to be closed. only available in wxWidgets 3.3.0 or later.
EVT_WEBVIEW_TITLE_CHANGED: Process a wxEVT_WEBVIEW_TITLE_CHANGED event, generated when the page title changes. Use GetString to get the title.
EVT_WEBVIEW_FULLSCREEN_CHANGED: Process a wxEVT_WEBVIEW_FULLSCREEN_CHANGED event, generated when the page wants to enter or leave fullscreen. Use GetInt to get the status. Not implemented for the IE backend and is only available in wxWidgets 3.1.5 or later.
EVT_WEBVIEW_SCRIPT_MESSAGE_RECEIVED: Process a wxEVT_WEBVIEW_SCRIPT_MESSAGE_RECEIVED event only available in wxWidgets 3.1.5 or later. For usage details see wx.html2.WebView.AddScriptMessageHandler .
EVT_WEBVIEW_SCRIPT_RESULT: Process a wxEVT_WEBVIEW_SCRIPT_RESULT event only available in wxWidgets 3.1.6 or later. For usage details see wx.html2.WebView.RunScriptAsync .
wxEVT_WEBVIEW_BROWSING_DATA_CLEARED: Process a wxEVT_WEBVIEW_BROWSING_DATA_CLEARED event only available in wxWidgets 3.3.0 or later. For usage details see wx.html2.WebView.ClearBrowsingData .
