The default state in Software Display GS1 - 12 in Software The default state barcode 39 for C#

The default state generate, create none none in none projectsgenerate code 39 c# Widgets the u none for none ser interacts with must have an initial state. That is, before the user does anything with the mouse or keyboard that would cause the widget to change state, it should look normal, as though nothing has happened to it yet. This is the default state.

The default state has a corresponding CSS class within the theming framework that is applied to widgets. You"re probably wondering why we don"t use the ancestor styles from the framework to show the user that the widget is in a default state. Why do we need a another class applied to widgets the user interacts with .

QR Code Safty [ 101 ]. Transforming Interaction States jQuery UI wid gets capable of user interaction need the default state because they may not necessarily inherit theme styles from container widgets such as ui-widget-content. It is a good thing that we want button widgets to look enticing, like they"re supposed to be clicked. If we were to let our clickable widgets inherit container theme styles, they would fade into the background as an afterthought.

The default state is also important from a more elusive design perspective. If widgets change state when a user interacts with them, they get a new state applied to them. If not for the default state, the widget would be going from being a stateless entity to suddenly having a state.

This doesn"t make much sense logically. It is better that widgets with the potential to change state are always in one state or another, never stateless..

Default state selectors In the previo us chapter, we looked at widget container CSS classes. These CSS selectors were fairly straightforward - "any element with this class" or "any input elements nested inside an element with this class". Just like widget containers, the jQuery UI theming framework uses classes for states.

The default state is called ui-state-default. The selectors used by this state are a little more involved than the widget container CSS selectors. Not only do we have nested elements that the default state affects, we also have groups of selectors required to make the default state behave as it"s supposed to.

The default state selector isn"t necessarily difficult to work with because it uses nesting and grouping selectors - it just has more moving parts than selectors in other areas of the CSS framework such as widget containers. In fact, the widget container classes are closely related to the default state class. The default state uses the ui-widget-content and ui-widget-header classes in its CSS selector.
