Wt::WBoxLayout - Another layout manager option illustrated in the example. WAnchor - Used for navigation by referencing internal paths and reacting to path changes. Wt::Auth - The authentication module used for user login via username/password or Google OAuth 2.0. Wt::Dbo - Used for database access and persistence of user information, as demonstrated in the Hangman game's ranking system. ``` -------------------------------- ### Mail Composer Example Overview Source: https://www.webtoolkit.eu/wt/documentation/examples/mail-composer Details the Wt Mail Composer example, highlighting asynchronous file uploads, progress bars, and advanced widget interactions. It mentions specific Wt classes like WSuggestionPopup, WFileUpload, and WProgressBar. ```en This example implements a GMail-like mail composer and shows among other things how to upload files asynchronously, showing a cross-browser upload progress bar and with support for multiple files. * The *ContactSuggestions* class provides auto-completion of the addressees in the To: Cc: and Bcc: fields. The widget derives from [WSuggestionPopup](//www.webtoolkit.eu/wt/doc/reference/html/classWt_1_1WSuggestionPopup.html). * The *AttachmentEdit* widget uses a [WFileUpload](//www.webtoolkit.eu/wt/doc/reference/html/classWt_1_1WFileUpload.html) to asynchronously upload files. The upload [progress bar](//www.webtoolkit.eu/wt/doc/reference/html/classWt_1_1WProgressBar.html) will work even in IE6. * The *Option* and *OptionList* classes show how stateless slots, a trick to handle events client-side but implement them still in C++, may be used even when the behaviour is not entirely stateless. In this case, the hiding of an Option affects neighboring visible options: an option needs a separator only if there is a neighbouring option. By **invalidating the stateless slot implementations** when state has changed, we can still use a stateless slot implementation and enjoy client-side event handling performance! ``` -------------------------------- ### Wt Treeview Drag and Drop Example Source: https://www.webtoolkit.eu/wt/documentation/examples/treeview An example demonstrating MVC functionality using Wt widgets, specifically focusing on drag and drop capabilities within tree and table views. It showcases the use of WTreeView, WTableView, and WSortFilterProxyModel. ```cpp // Example demonstrating Wt's MVC functionality with drag and drop // Uses WTreeView, WTableView, WSortFilterProxyModel // For full source code, refer to the Wt examples directory. ``` -------------------------------- ### Wt Library Documentation Links Source: https://www.webtoolkit.eu/wt/documentation/examples/mail-composer Provides links to essential Wt library documentation resources, including the main reference manual, specific tutorials, and the widget gallery for practical examples. ```en [Wt library overview](https://www.webtoolkit.eu/wt/doc/reference/html/overview.html) [Introduction to Wt](https://www.webtoolkit.eu/wt/doc/tutorial/wt.html) [Introduction to Wt::Dbo](https://www.webtoolkit.eu/wt/doc/tutorial/dbo.html) [Introduction to Wt::Auth](https://www.webtoolkit.eu/wt/doc/tutorial/auth.html) [Wt 4 reference](https://www.webtoolkit.eu/wt/doc/reference/html/) [Wt 3 reference](https://www.webtoolkit.eu/wt/wt3/doc/reference/html/) [Widget gallery](https://www.webtoolkit.eu/widgets) ``` -------------------------------- ### Wt Community and Support Resources Source: https://www.webtoolkit.eu/wt/documentation/examples/mail-composer Lists key community and support resources for Wt users, including forums, issue tracking, wiki, and the project's GitHub repository. ```en [Redmine](http://redmine.webtoolkit.eu/projects/wt) [forums](http://redmine.webtoolkit.eu/projects/wt/boards) [issues](http://redmine.webtoolkit.eu/projects/wt/issues) [wiki](http://redmine.webtoolkit.eu/projects/wt/wiki) [GitHub](https://github.com/emweb/wt) ``` -------------------------------- ### Wt MVC Views and Models Documentation Source: https://www.webtoolkit.eu/wt/documentation/examples/treeview Details on Wt's Model-View-Controller (MVC) components, including tree and table views, proxy models for sorting/filtering, and layout management. These components facilitate data rendering and interaction within Wt applications. ```APIDOC Wt MVC Views and Models: - WTreeView: - Description: Widget for rendering a Model's data in a tree structure. - Usage: Displays hierarchical data. - Related: WTableView, WSortFilterProxyModel. - WTableView: - Description: Widget for rendering a Model's data in a table structure. - Usage: Displays tabular data. - Related: WTreeView, WSortFilterProxyModel. - WSortFilterProxyModel: - Description: Implements sorting and filtering for another model. - Usage: Enhances data models with sorting and filtering capabilities. - Related: WTreeView, WTableView. - WBoxLayout: - Description: Nested layout managers (horizontal and vertical) for automatic window-filling layout with optional resize handles. - Usage: Manages widget positioning and resizing within layouts. - Related: Other layout managers. - WDialog: - Description: Supports modal and non-modal dialogs for prompting user input. - Usage: Creates pop-up windows for user interaction. - Related: WPopupMenu. - WPopupMenu: - Description: Displays a context-sensitive menu. - Usage: Provides options based on user context. - Related: WDialog. ``` -------------------------------- ### Wt Charting Widgets and Painting API Source: https://www.webtoolkit.eu/wt/documentation/examples/charts Demonstrates Wt's charting widgets built on its cross-browser painting API. This API uses browser features like VML, SVG, HTML5 canvas, or PNG for rendering within WPaintedWidget. It also shows how to share Models across multiple Views, like a table view and a chart, which both act as Views on the same item model. ```APIDOC Wt Charting Widgets and Painting API: Purpose: Showcase charting widgets and cross-browser painting API. Dependencies: Wt charting widgets, Wt painting API, WPaintedWidget, WTableView, WAbstractItemModel. Features: - Implements charting widgets on Wt's cross-browser painting API. - Painting API uses VML, SVG, HTML5 canvas, or PNG based on browser support. - Renders painted contents in WPaintedWidget. - Demonstrates Model-View architecture: sharing a Model between multiple Views (e.g., table and chart). Related Classes: - Wt::WPaintedWidget - Wt::WTableView - Wt::WAbstractItemModel Example Usage: - Run example: //www.webtoolkit.eu/wt/examples/charts/charts.wt - Browse source code: ../../../wt/src/charts ``` -------------------------------- ### Embed Simple Chat Widget in HTML Source: https://www.webtoolkit.eu/wt/documentation/examples/chat This snippet shows how to embed the SimpleChat Wt widget into an existing HTML page. It uses a script tag to load the chat functionality, which communicates with the server via Cross-Origin Ajax/WebSocket requests. The 'div' parameter specifies the target HTML element for the widget. ```HTML
