TitleBar

Since: BlackBerry 10.0.0

#include <bb/cascades/TitleBar>

Defines a title bar on a page.

The title bar consists of a title with optional actions for accepting or declining an action, or an optional set of selectable options, depending on the type of title bar. You can define the type of title bar to display using the kind property. Possible values are Default (allows the action buttons to be displayed), Segmented (allows a SegmentedControl to be displayed), and FreeForm (allows controls to be placed freely on the title bar). The actions will be displayed on the title bar, which is placed at the top of the screen.

Here's an example of a default title bar:

QML:

Page {
    titleBar: TitleBar {
        title : "This is a page title"
    }
}

C++:

TitleBar* tb = new TitleBar();
tb->setTitle("This is a page title");
Page* page = Page::create().titleBar(tb);

Here's a title bar containing options:

Page {
    titleBar: TitleBar {
        kind: TitleBarKind.Segmented
        options: [
            Option {
                text: "Todo"
                value: "todo"
            },
            Option {
                text: "Finished"
                value: "finished"
            },
            Option {
                text: "Chickened out"
                value: "chickened"
            }
        ]
    }
}

And lastly, this is a free-form title bar containing expandable content:

Page {
    titleBar: TitleBar {
        kind: TitleBarKind.FreeForm
        kindProperties: FreeFormTitleBarKindProperties {
            Container {
                layout: StackLayout { orientation: LayoutOrientation.LeftToRight }
                leftPadding: 10
                rightPadding: 10
                Label {
                    text: "Show expandable content"
                    textStyle {
                        color: Color.White
                    }
                    verticalAlignment: VerticalAlignment.Center
                    layoutProperties: StackLayoutProperties { spaceQuota: 1 }
                }
                CheckBox {
                    id: toggleExpanded
                    verticalAlignment: VerticalAlignment.Center
                }
            }
            expandableArea {
                content: RadioGroup {
                    Option { id: option1; text: "option 1"; selected: true }
                    Option { id: option2; text: "option 2" }
                    Option { id: option3; text: "option 3" }
                }
                indicatorVisibility: TitleBarExpandableAreaIndicatorVisibility.Hidden
                expanded: toggleExpanded.checked
                onExpandedChanged: {
                    toggleExpanded.checked = expanded
                }
            }
        }
    }
}

Properties

bb::cascades::ActionItem acceptAction

An action that will be displayed beside the title in the TitleBar.

This action should typically be used to accept or confirm some sort of action.

See also:

ActionItem

Since:

BlackBerry 10.0.0

bb::cascades::TitleBarAppearance::Type appearance

Specifies what appearance the TitleBar should have.

The default value is TitleBarAppearance::Type Default.

See also:

TitleBarAppearance

Since:

BlackBerry 10.0.0

bb::cascades::TriBool::Type branded

Specifies whether the TitleBar should use the colors associated with the current visual brand.

Currently, the only available brand color is blue (the default). In the future, there may be the possibility to choose from different branding options.

When branded is set to True, the title bar assumes the color associated with the current brand. When set to False, the title bar keeps the default color associated with the application's VisualStyle (either Light or Dark).

If the VisualStyle is Light, the branded title bar is used by default. If the VisualStyle is Dark, the branded control is still available, but not used by default.

The default value is TriBool::Type Undefined. Deprecated

do not use, use appearance

Since:

BlackBerry 10.0.0

bb::cascades::ActionItem dismissAction

An action that will be displayed beside the title in the TitleBar.

This action should typically be used to cancel an action or process, or to dismiss or close the current page.

See also:

AbstractActionItem

Since:

BlackBerry 10.0.0

bb::cascades::TitleBarKind::Type kind

The kind of TitleBar to create.

This property can only be set once during the construction of the TitleBar. Possible values for this property are Default, Segmented, and FreeForm.

The Default state displays the title bar with left-aligned title text that can be set using the title property. It is possible to add two action buttons to the Default title bar, one on either side of the title. If one or more action buttons are shown, the title text will be center-aligned.

If kind is set to Segmented, the title, acceptAction, and dismissAction properties are not used, and the title text will not be displayed. The title bar will instead display up to four options. These options can be set using the options property.

Since:

BlackBerry 10.0.0

bb::cascades::AbstractTitleBarKindProperties kindProperties

The properties associated with a certain title bar kind.

Depending on the kind that has been set on the TitleBar, a different set of properties are valid. These different sets properties are bundled in classes inheriting from AbstractTitleBarKindProperties.

Since:

BlackBerry 10.1.0

QDeclarativeListProperty< bb::cascades::Option > options[read-only]

The list of Option controls in the TitleBar.

The list is empty initially if no options have been added.

Since:

BlackBerry 10.0.0

bb::cascades::TitleBarScrollBehavior::Type scrollBehavior

The title bar scroll behavior for the Page.

By default, the scrollBehavior of a Page is TitleBarScrollBehavior::Default.

Note:

: The title bar can't be immersive (ChromeVisibility::Overlay) and have a non sticky scroll behavior (TitleBarScrollBehavior::NonSticky) at the same time. ScrollBehavior will have precedence over the immersive visibility.

Since:

BlackBerry 10.1.0

int selectedIndex

The index of the currently selected option.

The selectedIndexChanged() signal is emitted when the index of the selected option is changed.

The default selectedIndex is SelectedIndexNone, meaning that no option is selected.

Since:

BlackBerry 10.0.0

bb::cascades::Option selectedOption

The currently selected Option.

The selectedOptionChanged() signal is emitted when the selected option is changed.

The default selectedOption is 0, meaning that no option is selected.

Since:

BlackBerry 10.0.0

bool selectedOptionSet[read-only]

Indicates whether any option in the TitleBar is currently selected.

This property is set to true if any option is selected, and is set to false otherwise.

This property can be used to determine if any option is currently selected, in addition to examining the selectedIndex property (typically from QML). Specifically, if the hasSelectedOption property is false, the selectedIndex property will be set to SelectedIndexNone, which is not accessible from QML.

TitleBar {
    onSelectedOptionSetChanged: {
        if (selectedOptionSet) {
            console.log("Selected option with index: " + selectedIndex);
        } else {
            console.log("No selected options");
        }
    }
}

When the value of this property changes, the selectedOptionSetChange() signal is emitted.

Since:

BlackBerry 10.0.0

QVariant selectedValue[read-only]

The value of the currently selected Option.

The selectedValueChanged() signal is emitted when the selected option's value is changed.

The default selectedValue is an invalid QVariant if the selected option has no value set or no option is selected.

See also:

QVariant, QVariant::Invalid

Since:

BlackBerry 10.0.0

QString title

The title text to display on the TitleBar.

The default value is QString::Null, indicating that no title is set.

Since:

BlackBerry 10.0.0

bb::cascades::ChromeVisibility::Type visibility

The visibility mode of the TitleBar.

The default visibility state of a title bar is ChromeVisibility::Default.

Note:

Since:

BlackBerry 10.0.0

QDeclarativeListProperty< QObject > attachedObjects[read-only]

A hierarchical list of the UIObject's attached objects.

This QDeclarativeListProperty can contain any QObject. When a QObject is added to property, the UIObject takes ownership of the attached object.

This feature is typically used from QML to specify business logic object or any other shared objects for the subnodes of this UIObject. In C++ the same functionality can be achived by setting a parent of a QObject to be attached to the QObject which is going to own it.

QML usage example (MyObject is a custom class registered for QML using the qmlRegisterType() function):

Container {
    Label { text: "Title: " + myObject.title } 
    Label { text: "Subject: " + myObject.subject }
    attachedObjects: [
        MyObject { id: myObject
            title: "Hello World"
            subject: "Nice Day"
        }
    ]
}

Since:

BlackBerry 10.0.0

QString objectName

This property is overridden from QObject.

As the objectName property is overridden from the QObject class, this signal will not be emitted if setObjectName() function is called directly on QObject.

The default value of this property is QString::null.

See also:

QObject::objectName().

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

void creationCompleted ()

This signal is emitted only when this object is instantiated as a result of loading a QML document and creating the root node, or when an object is being constructed using its builder class.

This signal is emitted only 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 is emitted to indicate 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.
