TabbedPane

Since: BlackBerry 10.0.0

#include <bb/cascades/TabbedPane>

A navigation control that allows the user to switch between tabs.

The tabs can be used to either completely replace displayed content by setting new panes or to filter existing content in a single pane based on which tab is currently selected.

The Tab objects in the TabbedPane are added to the Action bar, which is a horizontal bar displayed at the bottom of the screen. The tabs on the Action bar can be pressed to switch to display their content. The Tab objects take an AbstractPane as their content. If the content is not 0, it will be displayed in the TabbedPane when the corresponding tab is selected.

If the TabbedPane has only one Tab and the content of that Tab has no actions, the Action bar is not displayed since there aren't any additional tabs or actions to be displayed.

The first added Tab becomes the active one.

If the content of the Tab that is being displayed has any ActionItem objects associated with it, these actions take priority and are placed on the Action bar, while the other tabs are pushed to the side bar. This behavior can be changed by setting the showTabsOnActionBar property to true. If showTabsOnActionBar is true, tabs will be placed on the Action bar and actions will be placed in the Action menu.

A TabbedPane with three tabs and an action

The user can access tabs or actions that are not present on the Action bar by pressing the overflow tab, which is automatically added to the Action bar when it is needed.

If a tab is selected that is not currently present on the Action bar, the side bar will then change to the active-tab state and show the title and image of that tab along with an overflow symbol.

It is possible for the application to programmatically change the appearance of the sidebar by setting the property sidebarState.

A tab can display a visual notification image if there is new content available. If any tab that is only shown in the side bar contains such a visual notification, the overflow tab will also display such a visual notification. This visual notification will remain on the overflow tab until the corresponding tab(s) have been displayed (e.g. by opening the side bar) or the visual notification is removed from all tabs that are only visible in the side bar and that had new content.

Here's an example of a TabbedPane with three tabs, each with its own page and set of actions. The tabs are set to show on the Action bar so that the actions get pushed to the Action menu.

QML implementation:

 TabbedPane {
     showTabsOnActionBar: true
     Tab {
         title: "Home"
         Page {
             id: page1
             actions: [
                 ActionItem {
                     title: "New"
                 },
                 ActionItem {
                     title: "Delete"
                 }
             ]
         }
     }
     Tab {
         title: "Options"
         Page {
             id: page2
             actions: [
                 ActionItem {
                     title: "Edit"
                 },
                 ActionItem {
                     title: "Save"
                 }
             ]
         }
     }
     Tab {
         title: "Help"
         Page {
             id: page3
             actions: [
                 ActionItem {
                     title: "Search"
                 },
                 ActionItem {
                     title: "Browse"
                 }
             ]
         }
     }
 }

C++ implementation:

 TabbedPane* tabbedPane = TabbedPane::create()
     .showTabsOnActionBar(true)
     .add(Tab::create()
         .title("Home")
         .content(Page::create()
             .addAction(ActionItem::create().title("New"))
             .addAction(ActionItem::create().title("Delete"))))
     .add(Tab::create()
         .title("Options")
         .content(Page::create()
             .addAction(ActionItem::create().title("Edit"))
             .addAction(ActionItem::create().title("Save"))))
     .add(Tab::create()
         .title("Help")
         .content(Page::create()
             .addAction(ActionItem::create().title("Search"))
             .addAction(ActionItem::create().title("Browse"))));

To get the actions displayed on the Action bar and the tabs in the Tab menu, the showTabsOnActionBar property must be set to false and the ActionBar.placement property for each action must be set to ActionBarPlacement.OnBar. Here's how a TabbedPane looks with the actions on the Action bar and the tabs in the Tab menu:

In addition to switching between pages, tabs can also be used for filtering content that appears on the screen. Here's an example that shows how to change the text for a label by using tabs.

 TabbedPane {
     showTabsOnActionBar: true
     activePane:
         Page {
             Label {
                 id: label
                 text: "What do you like more, kittens or puppies?"
             }
         }
 
     Tab { 
         title: "Puppies"
         onTriggered: label.text = "I love puppies!"
     }
 
     Tab {
         title: "Kittens"
         onTriggered: label.text = "I love kittens!"
     }
 }

Properties

bb::cascades::AbstractPane activePane

The AbstractPane which is currently being shown by the TabbedPane.

Since:

BlackBerry 10.0.0

bb::cascades::Tab activeTab

The Tab that is currently active in the TabbedPane.

The active tab is 0 if the TabbedPane doesn't have any children.

The activeTabChanged() signal is emitted when this property changes.

Since:

BlackBerry 10.0.0

QDeclarativeListProperty tabs[read-only]

A set of Tab objects added to the TabbedPane.

For each Tab in the TabbedPane, a tab is added to the Action bar, which can be pressed to switch to its corresponding content. If the active Tab has actions added to it, they will be displayed in the Action bar.

See also:

Tab, Page, NavigationPane

Since:

BlackBerry 10.0.0

bool peekEnabled

Indicates whether peeking from within the current Page should be enabled.

When enabled, dragging or swiping to the right inside the content of the Page will reveal the Tab menu.

This property only controls whether or not peeking is enabled within the content area of the Page. Peeking is always enabled on the Action bar, even if this property is disabled.

The default value is true (enabled).

Since:

BlackBerry 10.0.0

bool showTabsOnActionBar

Specifies whether tabs should take priority in the Action bar instead of action items.

If the content of the Tab that is being displayed has any ActionItem objects associated with it, these actions take priority and are placed on the Action bar, while the other tabs are pushed to the side bar. This behavior can be changed by setting the showTabsOnActionBar property to true. If showTabsOnActionBar is true, tabs for will be placed on the Action bar and actions will be placed in the side bar.

The default value is false.

Since:

BlackBerry 10.0.0

bb::cascades::SidebarState::Type sidebarState

The current visibility state of the sidebar.

The default state is Hidden. The other available visibility states are VisibleCompact, and VisibleFull.

Since:

BlackBerry 10.0.0

bb::cascades::SidebarVisualState::Type sidebarVisualState[read-only]

The current visual state of the sidebar.

Since:

BlackBerry 10.0.0

bb::cascades::AbstractA11yObject accessibility[read-only]

Defines this pane's accessibility object.

See also:

Control::accessibility

Since:

BlackBerry 10.2.0

QDeclarativeListProperty< QObject > attachedObjects[read-only]

A hierarchical list of the UIObject's attached objects.

Since:

BlackBerry 10.0.0

bool builtInShortcutsEnabled

Enables or disables all AbstractPane's core shortcuts.

This property is used when all AbstractPane's core shortcuts should be enabled or disabled.

Since:

BlackBerry 10.2.0

QString objectName

This property is overridden from QObject.

See also:

QObject::objectName().

Since:

BlackBerry 10.0.0

bb::cascades::PaneProperties paneProperties

The pane properties for this AbstractPane.

The paneProperties property specifies data that the parent AbstractPane may use. The type of pane properties of the child must match up with parent. For example, if you add a Page to a NavigationPane, you must use NavigationPaneProperties.

By default, the paneProperties of an AbstractPane is 0.

Since:

BlackBerry 10.0.0

QObject parent[read-only]

A read-only property that represents this object's parent.

The parent of an object is specified using QObject::setParent(QObject*). The purpose of the property is to expose the object's parent to QML.

This property is read-only to prevent modifications from QML, where typically the parent is declaratively set. In C++ code, the parent can be explicitly set using QObject::setParent(QObject*), or implicitly set by adding it to a visual container.

The default value of this property is 0.

Since:

BlackBerry 10.0.0

bool peekedAt[read-only]

Indicates whether this AbstractPane is being "peeked" at.

If true, the pane is currently being revealed by peeking from a Sheet or a Page within a NavigationPane. By default, the value is false, indicating that the pane is not currently being peeked at.

If a NavigationPane is being peeked at, both the NavigationPane and its currently visible page will return true for the peekedAt property.

As a convenience, there are two signals available called peekStarted and peekEnded, which are emitted when a peek on the AbstractPane starts or ends.

The peekedAtChanged() signal is emitted when peekedAt changes.

Since:

BlackBerry 10.0.0

bb::cascades::UIConfig ui[read-only]

An object that gives access to unit conversion routines.

QML use:

        // Size using design units
        Container {
            preferredWidth: ui.du(12)
            preferredHeight: ui.du(5)
        }

        // Size using design units, snap to whole pixels
        Container {
            preferredWidth: ui.sdu(13.5)
            preferredHeight: ui.sdu(7.5)
        }

        // Size using absolute pixel values
        Container {
            preferredWidth: ui.px(150)
            preferredHeight: ui.px(50)
        }

C++ use:

Container *container1 = Container::create().background(Color::Red);
UIConfig *ui = container1->ui();
container1->setPreferredWidth(ui->du(12));
container1->setPreferredHeight(ui->du(5));

Container *container2 = Container::create().background(Color::Green);
container2->setPreferredWidth(ui->sdu(13.5));
container2->setPreferredHeight(ui->sdu(7.5));

Container *container3 = Container::create().background(Color::Blue);
container3->setPreferredWidth(ui->px(150));
container3->setPreferredHeight(ui->sdu(50));

void sidebarStateChanged (
bb::cascades::SidebarState::TypenewSidebarState)

Emitted when sidebarState property changed.

Note:

Due to a work around for a Qt Core issue with accessing enums from QML the argument of this signal doesn't follow naming convention for signals in which the signal arguments are typically named to match the associated property's name. Use the object's property to access current property value instead of the signal argument to avoid runtime errors (i.e. use sidebarState instead of newSidebarState).

Parameters
newSidebarState	The new value of the sidebarState property.

Since:

BlackBerry 10.0.0

void sidebarVisualStateChanged (
bb::cascades::SidebarVisualState::TypenewSidebarVisualState)

void creationCompleted ()

Emitted when this object is instantiated as a result of loading a QML document and creating the root node (only after the root component that caused this instantiation has completed construction), or when the object is being constructed from its builder class.

This signal indicates that the construction and initialization of the object has been completed, the properties are initialized, and any QML binding values have been assigned to the object.

This signal is not emitted when the object is constructed from C++ using the constructor. If the object is constructed using its builder class, the signal is emitted when the the builder class returns the fully constructed object.

This signal can be used when there is an activity that needs to be performed, such as a property state integrity verification after the object is instantiated from a QML document or a builder, but before control is returned to the application.
