Description

Helper widget to simplify construction and wiring of a [Notebook] widget.

Gtk::Notebook is quite powerful container foundation to build complex dialog widgets with multiple pages on tabs. However, the construction, wiring and setup is notoriously tedious, due to the repetitiveness and the sheer amount of child widgets spread over various pages.

This design draft is an attempt to mitigate the required boilerplate, without overly much obscuring the structure. The basic idea is to package each page into a locally defined child struct, which is actually heap allocated and managed automatically. This way, each child page gets its own namespace, and wiring to other components is made explicit by passing named ctor arguments – while the overall structure of building and wiring of widgets stays close to the habits of programming with GTKmm.

• define the pages as custom widgets, typically just as locally known struct types
• invoke #buildPage passing the type and tab label for each page
• define the wiring of the components within a page in the page's ctor
• possibly pass external dependencies for wiring into that ctor

  Note

  the page widgets are actually heap allocated and managed automatically
