Detailed Description

Implement this interface to handle events related to browser display state.

The methods of this class will be called on the UI thread.

Member Function Documentation

◆ OnAddressChange()

virtual void CefDisplayHandler::OnAddressChange ( CefRefPtr< CefBrowser browser,
CefRefPtr< CefFrame frame,
const CefString url 
)
inlinevirtual

Called when a frame's address has changed.

◆ OnAutoResize()

virtual bool CefDisplayHandler::OnAutoResize ( CefRefPtr< CefBrowser browser,
const CefSize new_size 
)
inlinevirtual

Called when auto-resize is enabled via CefBrowserHost::SetAutoResizeEnabled and the contents have auto-resized.

|new_size| will be the desired size in view coordinates. Return true if the resize was handled or false for default handling.

◆ OnConsoleMessage()

virtual bool CefDisplayHandler::OnConsoleMessage ( CefRefPtr< CefBrowser browser,
cef_log_severity_t  level,
const CefString message,
const CefString source,
int  line 
)
inlinevirtual

Called to display a console message.

Return true to stop the message from being output to the console.

◆ OnCursorChange()

virtual bool CefDisplayHandler::OnCursorChange ( CefRefPtr< CefBrowser browser,
CefCursorHandle  cursor,
cef_cursor_type_t  type,
const CefCursorInfo custom_cursor_info 
)
inlinevirtual

Called when the browser's cursor has changed.

If |type| is CT_CUSTOM then |custom_cursor_info| will be populated with the custom cursor information. Return true if the cursor change was handled or false for default handling.

◆ OnFaviconURLChange()

virtual void CefDisplayHandler::OnFaviconURLChange ( CefRefPtr< CefBrowser browser,
const std::vector< CefString > &  icon_urls 
)
inlinevirtual

Called when the page icon changes.

◆ OnFullscreenModeChange()

virtual void CefDisplayHandler::OnFullscreenModeChange ( CefRefPtr< CefBrowser browser,
bool  fullscreen 
)
inlinevirtual

Called when web content in the page has toggled fullscreen mode.

If |fullscreen| is true the content will automatically be sized to fill the browser content area. If |fullscreen| is false the content will automatically return to its original size and position. With Alloy style the client is responsible for triggering the fullscreen transition (for example, by calling CefWindow::SetFullscreen when using Views). With Chrome style the fullscreen transition will be triggered automatically. The CefWindowDelegate::OnWindowFullscreenTransition method will be called during the fullscreen transition for notification purposes.

◆ OnLoadingProgressChange()

virtual void CefDisplayHandler::OnLoadingProgressChange ( CefRefPtr< CefBrowser browser,
double  progress 
)
inlinevirtual

Called when the overall page loading progress has changed.

|progress| ranges from 0.0 to 1.0.

◆ OnMediaAccessChange()

virtual void CefDisplayHandler::OnMediaAccessChange ( CefRefPtr< CefBrowser browser,
bool  has_video_access,
bool  has_audio_access 
)
inlinevirtual

Called when the browser's access to an audio and/or video source has changed.

◆ OnStatusMessage()

virtual void CefDisplayHandler::OnStatusMessage ( CefRefPtr< CefBrowser browser,
const CefString value 
)
inlinevirtual

Called when the browser receives a status message.

|value| contains the text that will be displayed in the status message.

◆ OnTitleChange()

virtual void CefDisplayHandler::OnTitleChange ( CefRefPtr< CefBrowser browser,
const CefString title 
)
inlinevirtual

Called when the page title changes.

◆ OnTooltip()

virtual bool CefDisplayHandler::OnTooltip ( CefRefPtr< CefBrowser browser,
CefString text 
)
inlinevirtual

Called when the browser is about to display a tooltip.

|text| contains the text that will be displayed in the tooltip. To handle the display of the tooltip yourself return true. Otherwise, you can optionally modify |text| and then return false to allow the browser to display the tooltip. When window rendering is disabled the application is responsible for drawing tooltips and the return value is ignored.
