public class SectionStackSection
extends RefDataClass

Section descriptor used by a SectionStack to describe a section of items which are shown or hidden together along with their associated header.

A SectionStackSection can't be modified once it's been added to a SectionStack, which creates its section header (by default a SectionHeader, but see SectionStack.sectionHeaderClass). After that, you must call the appropriate SectionStack method to modify a section property, or the section header getter method to get the updated property value. As a convenience, we route several SectionStackSection setter methods to the SectionStack for you after the SectionStackSection has been added to it, but with the exception of items, you'll always get the original property values when calling a getter directly on a SectionStackSection.

Additional SectionHeader properties set on the SectionStackSection not explicitly documented, such as "iconAlign" or "prompt", are supported - use setAttribute().

Layout, LayoutMember overview and related methods

setCanReorder

public void setCanReorder(java.lang.Boolean canReorder)

If set to false, then this sectionHeader will not be able to be dragged to perform a drag reorder, if SectionStack.canReorderSections is true. You can also disable dropping other sections before this one by setting canDropBefore to false.

Parameters:

canReorder - New canReorder value. Default value is null

setCanTabToHeader

public void setCanTabToHeader(java.lang.Boolean canTabToHeader)

If true, the header for this Section will be included in the page's tab order for accessibility. May also be set at the SectionStack level via SectionStack.canTabToHeaders.

See Accessibility.

Parameters:

canTabToHeader - New canTabToHeader value. Default value is null

getCanTabToHeader

public java.lang.Boolean getCanTabToHeader()

If true, the header for this Section will be included in the page's tab order for accessibility. May also be set at the SectionStack level via SectionStack.canTabToHeaders.

See Accessibility.

Returns:

Current canTabToHeader value. Default value is null

setClipTitle

public void setClipTitle(java.lang.Boolean clipTitle)

If the title for this section header is too large for the available space, should the title be clipped?

This feature is supported only in browsers that support the CSS UI text-overflow property (IE6+, Firefox 7+, Safari, Chrome, Opera 9+).

Parameters:

clipTitle - New clipTitle value. Default value is true

getClipTitle

public java.lang.Boolean getClipTitle()

If the title for this section header is too large for the available space, should the title be clipped?

setControls

public void setControls(Canvas... controls)

Custom controls to be shown on top of this section header.

These controls are shown in the SectionHeader.controlsLayout.

Note that this is an init-time property. If you need to dynamically change what controls are displayed to the user, we would recommend embedding the controls in a Layout or similar container. This will allow you to show/hide or add/remove members at runtime by manipulating the existing control(s) set up at init time.

Parameters:

controls - New controls value. Default value is null

See Also:

Custom Controls Example

getControls

public Canvas[] getControls()

setName

public void setName(java.lang.String name)

Identifier for the section. This can be used later in calls to SectionStack APIs such as SectionStack.expandSection() and SectionStack.collapseSection(). Note that if no name is specified for the section, one will be auto-generated when the section is created. This property should be a string which may be used as a valid JavaScript identifier (should start with a letter and not contain space or special characters such as "*").

Parameters:

name - New name value. Default value is null

getName

public java.lang.String getName()

setExpanded

public void setExpanded(java.lang.Boolean expanded)

Sections default to the collapsed state unless showHeader is set to false in which case they default to the expanded state. This attribute allows you to explicitly control the expand/collapse state of the section by overriding the above default behavior.

Parameters:

expanded - expanded Default value is false

setHidden

public void setHidden(java.lang.Boolean hidden)

Sections default to the visible state. This attribute allows you to explicitly control the visible/hidden state of the section by overriding the above default behavior.

Assign a new set of Canvases to this section. These Canvases will be shown and hidden together.

Parameters:

items - list of Canvases that constitute the section

getItems

public Canvas[] getItems()

Return the items in this SectionStackSection

Returns:

the items in this SectionStackSection

addItem

public void addItem(Canvas item)

Adds a new Canvas to this section, at the end.

Parameters:

new - Canvas to add as item

getSectionStack

public SectionStack getSectionStack()

getSectionHeader

public SectionHeader getSectionHeader()

Once a SectionStackSection has been applied to a SectionStack, this method may be used to return a pointer to the SectionHeader for this section

Returns:

the SectionHeader for the section

getID

public java.lang.String getID()

Optional ID for the section. If useGlobalSectionIDs is true, this property will be applied to the generated SectionStackHeader widget as a standard widget ID, meaning it should be unique within a page.

Backcompat Note: Section stack sections may be uniquely identified within a stack via the name attribute (introduced in Jan 2010). Prior to this, the section ID attribute was used in this way (and would not be applied to the section header as a widget ID). For backwards compatibility this is still supported: If section.name is unspecified for a section but section.ID is set, the ID will be used as a default name attribute for the section. For backwards compatibility we also disable the standard behavior of having the section.ID being applied to the generated section header (thereby avoiding the page-level uniqueness requirement) by defaulting useGlobalSectionIDs to false.

Returns:

String

setID

public void setID(java.lang.String ID)

Optional ID for the section. If useGlobalSectionIDs is true, this property will be applied to the generated SectionStackHeader widget as a standard widget ID, meaning it should be unique within a page.
