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()
|
inlinevirtual |
Called when a frame's address has changed.
◆ OnAutoResize()
|
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()
|
inlinevirtual |
Called to display a console message.
Return true to stop the message from being output to the console.
◆ OnCursorChange()
|
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()
|
inlinevirtual |
Called when the page icon changes.
◆ OnFullscreenModeChange()
|
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 the Alloy runtime the client is responsible for triggering the fullscreen transition (for example, by calling CefWindow::SetFullscreen when using Views). With the Chrome runtime the fullscreen transition will be triggered automatically. The CefWindowDelegate::OnWindowFullscreenTransition method will be called during the fullscreen transition for notification purposes.
◆ OnLoadingProgressChange()
|
inlinevirtual |
Called when the overall page loading progress has changed.
|progress| ranges from 0.0 to 1.0.
◆ OnMediaAccessChange()
|
inlinevirtual |
Called when the browser's access to an audio and/or video source has changed.
◆ OnStatusMessage()
|
inlinevirtual |
Called when the browser receives a status message.
|value| contains the text that will be displayed in the status message.
◆ OnTitleChange()
|
inlinevirtual |
Called when the page title changes.
◆ OnTooltip()
|
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.
