Theme based on the Bootstrap 5 CSS framework.
This theme implements support for building a Wt web application that uses Bootstrap 5 as a theme for its (layout and) styling.
Using this theme, various widgets provided by the library are rendered using markup that is compatible with Bootstrap 5. The bootstrap theme is also extended with a proper (compatible) styling of widgets for which bootstrap does not provide styling (table views, tree views, sliders, etc...).
By default, the theme will use CSS and JavaScript resources that are shipped together with the Wt distribution, but you can replace the CSS with custom-built CSS by reimplementing styleSheets().
Although this theme styles individual widgets correctly, for your web application's layout you are recommended to use WTemplate in conjunction with Bootstrap's CSS classes. For this we refer to Bootstrap's documentation at https://getbootstrap.com.

overridevirtual |
Applies the theme to a child of a composite widget.
The widgetRole
indicates the role that child
has within the implementation of the widget
.
Implements Wt::WTheme.
|
overridevirtual |
Applies the theme to a DOM element that renders a widget.
The element
is a rendered representation of the widget
, and may be further customized to reflect the theme.
Implements Wt::WTheme.
|
overridevirtual |
Called when the theme is assigned to a WApplication.
This allows the theme to do things like load resource bundles when it is added to an application using WApplication::setTheme().
The default implementation does nothing.
Reimplemented from Wt::WTheme.
|
overridevirtual |
Returns a theme name.
Returns a unique name for the theme. This name is used by the default implementation of resourcesUrl() to compute a location for the theme's resources.
Implements Wt::WTheme.
|
overridevirtual |
Returns the URL where theme-related resources are stored.
The default implementation considers a folder within Wt's resource directory, based on the theme name().
Reimplemented from Wt::WTheme.
|
overridevirtual |
Sets the data target for a widget.
The widget
is a bootstrap element that requires a data-bs-target attribute to function (with Bootstrap JS). The target
is the element that is targeted by the widget
.
Reimplemented from Wt::WTheme.
|
overridevirtual |
Returns a vector with stylesheets for the theme.
This should return a vector with stylesheets that implement the theme. This list may be tailored to the current user agent, which is read from the application environment.
Implements Wt::WTheme.
|
overridevirtual |
Returns a generic CSS class name for the chosen role.
Implements Wt::WTheme.
