Detailed Description

Theme based on the Twitter Bootstrap CSS framework.

This theme implements support for building a Wt web application that uses Twitter Bootstrap as a theme for its (layout and) styling. The theme comes with CSS from Bootstrap version 2.2.2 or version 3.1. Only the CSS components of twitter bootstrap are used, but not the JavaScript (i.e. the functional parts), since the functionality is already built-in to the widgets from the library.

Using this theme, various widgets provided by the library are rendered using markup that is compatible with Twitter Bootstrap. 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 resources that are shipped together with the Wt distribution, but since the Twitter Bootstrap CSS API is a popular API for custom themes, you can easily replace the CSS with custom-built CSS (by reimplementing styleSheets()).

Although this theme facilitates the use of Twitter Bootstrap with Wt, it is still important to understand how Bootstrap expects markup to be, especially related to layout using its grid system, for which we refer to the official bootstrap documentation, see http://getbootstrap.com

Member Function Documentation

void Wt::WBootstrapTheme::apply ( WWidget widget,
WWidget child,
int  widgetRole 
) const
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.

void Wt::WBootstrapTheme::apply ( WWidget widget,
DomElement element,
int  elementRole 
) const
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.

std::string Wt::WBootstrapTheme::name ( ) const
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.

bool Wt::WBootstrapTheme::responsive ( ) const

Returns whether responsive features are enabled.

See also
setResponsive()
void Wt::WBootstrapTheme::setFormControlStyleEnabled ( bool  enabled)

Enables form-control on all applicable form widgets.

This is relevant only for bootstrap 3.

By applying "form-control" on form widgets, they will become block level elements that take the size of the parent (which is in bootstrap's philosphy a grid layout).

The default value is true.

void Wt::WBootstrapTheme::setResponsive ( bool  responsive)

Enables responsive features.

Responsive features can be enabled only at application startup. For bootstrap 3, you need to use the progressive bootstrap feature of Wt (see see 10.2 General application settings (wt_config.xml)) as it requires setting HTML meta flags.

Responsive features are disabled by default.

void Wt::WBootstrapTheme::setVersion ( BootstrapVersion  version)

Sets the bootstrap version.

The default bootstrap version is 2 (but this may change in the future and thus we recommend setting the version).

Since Twitter Bootstrap breaks its API with a major version change, the version has a big impact on how how the markup is done for various widgets.

Note that the two Bootstrap versions have a different license: Apache 2.0 for Bootstrap version 2.2.2, and MIT for version 3.1. See these licenses for details.

std::vector< WLinkedCssStyleSheet > Wt::WBootstrapTheme::styleSheets ( ) const
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.

std::string Wt::WBootstrapTheme::utilityCssClass ( int  utilityCssClassRole) const
overridevirtual

Returns a generic CSS class name for the chosen role.

See also
WTheme::utilityCssClassRole

Implements Wt::WTheme.

BootstrapVersion Wt::WBootstrapTheme::version ( ) const

Returns the bootstrap version.
