◆ get_control_type()

virtual const std::string& gui2::styled_widget::get_control_type ( ) const

pure virtual

Returns the type of this styled_widget.

This is used as the control_type parameter for get_control.

Do note that each widget also must have a public static type() function; it's use to implement this function. The reason for this system is twofold:

1) Due to an oddity in C++, one technically may not call a virtual function in a derived class's initializer list, which we do liberally. Calling it in the constructor body is fine, but doing so in the initializer list is technically undefined behavior and will give "invalid vptr" errors under UBSanitizer.

2) Having a static type getter allows the type string to be fetched without constructing an instance of the widget. A good example of this usecase is in build_single_widget_instance.

unsigned int gui2::styled_widget::cached_text_font_size_ = 0

mutableprivate

Contains the evaluated text_font_size from the configuration.

We want to allow formulas in the value of text_font_size, since the desired font size can depend on parameters of the screen and window. But we don't want to have to recompute the value of the formula all the time. This member variable is the cache for the evaluated font size.

◆ canvases_

std::vector<canvas> gui2::styled_widget::canvases_

private

Holds all canvas objects for a styled_widget.

A styled_widget can have multiple states, which are defined in the classes inheriting from us. For every state there is a separate canvas, which is stored here. When drawing the state is determined and that canvas is drawn.

Contains the pointer to the configuration.

Every styled_widget has a definition of how it should look, this contains a pointer to the definition. The definition is resolution dependent, where the resolution is the size of the Wesnoth application window. Depending on the resolution widgets can look different, use different fonts. Windows can use extra scrollbars use abbreviations as text etc.

◆ renderer_

font::pango_text gui2::styled_widget::renderer_

mutableprivate

Text renderer object used for size calculations.

Note this is not used to actually render any text, only to get the dimensions of the text for layout purposes. The actual text rendering happens in the canvas. This is kept as a class member since creating a pango_text object is quite expensive.

Todo:: Maybe if still too slow we might also copy this cache to the canvas so it can reuse our results, but for now it seems fast enough. Unfortunately that would make the dependency between the classes bigger as wanted.
