Package reahl.web.bootstrap.tabbedpanel

New in version 3.2.

TabbedPanels are used to save space by stacking different panels on top of one another. While each panel has its own contents only the top panel is visible, thus taking up visual space of only one such panel.

TabbedPanel

class reahl.web.bootstrap.tabbedpanel.TabbedPanel(view, nav_layout=None)

A Widget that appears as having multiple panels of content stacked on top of one another – with only one panel visible at a time.

Each content panel appears to have a label sticking out (its “tab”). When the user clicks on a different Tab, its panel is raised to the top and thus made visible. This is done without refreshing the entire page, provided that JavaScript is available on the user agent.

Parameters:
query_fields

Used to declare the arguments of this Widget on its class.

Override this class attribute to declare arguments this Widget, each described by a Field.

When constructed, the Widget uses the names and validation details of each Field to parse values for its arguments from the current query string. The resultant argument values are set as attributes on this Widget (with names matching the argument names).

To declare arguments on your own Widget class, assign a ExposedNames instance to query_fields and then assign a single-argument callable for each Widget argument to it. This callable will be called with the Widget instance as argument, and should return a Field describing it:

class MyWidget(Widget):
    query_fields = ExposedNames()
    query_fields.my_argument = lambda i: Field()

Changed in version 6.1: This used to be set up using a method using an exposed decorator.

add_tab(tab)
