# Titanium.UI.TableViewSection
A table view section is a container within a table used to organize table view rows.
# Overview
Use the Titanium.UI.createTableViewSection method or <TableViewSection>
Alloy element to
create a TableViewSection
.
Before the table is rendered, the TableViewSection
Titanium.UI.TableViewSection.add
method may be used to add Titanium.UI.TableViewRow objects to a section. After
it is rendered, one of the TableView
Titanium.UI.TableView.insertRowBefore,
Titanium.UI.TableView.insertRowAfter, or
Titanium.UI.TableView.appendRow methods must be used instead.
To remove a row from a section after the table is rendered, use the TableView
Titanium.UI.TableView.deleteRow method.
In order for a section to be visible, either its headerTitle
or headerView
property must be
configured.
Starting in Release 3.0, you can directly manipulate the sections in a table using the
following TableView
APIs:
- To set all sections in a table view at one time, use the
TableView
Titanium.UI.TableView.sections property. - To add an individual section after a table view is rendered, use either the
TableView
Titanium.UI.TableView.insertSectionBefore or Titanium.UI.TableView.insertSectionAfter method. - To add one or more sections to the end of a table view after it is rendered, use the
TableView
Titanium.UI.TableView.appendSection method. - To remove an individual section after a table view is rendered, use the
TableView
Titanium.UI.TableView.deleteSection method.
Prior to Release 3.0, adding or removing sections individually is not supported. Instead, use the
TableView
Titanium.UI.TableView.data property to refresh the whole table with a
new section layout.
See the description and examples sections of Titanium.UI.TableView for more details
about how to use TableViewSection
.
Note: On some platforms, TableViewSection
may be implemented as a type of view
(that is, an object that inherits from Titanium.UI.View). However, this is an
implementation detail. For portability, you should only use the documented APIs on
table view sections.
# Properties
# apiName READONLY
The name of the API that this proxy corresponds to.
The value of this property is the fully qualified name of the API. For example, Titanium.UI.Button
returns Ti.UI.Button
.
# bubbleParent
Indicates if the proxy will bubble an event to its parent.
Some proxies (most commonly views) have a relationship to other proxies, often established by the add() method. For example, for a button added to a window, a click event on the button would bubble up to the window. Other common parents are table sections to their rows, table views to their sections, and scrollable views to their views. Set this property to false to disable the bubbling to the proxy's parent.
Default: true
Title of this section footer.
Using this property and footerView
together is not supported. Use one or the other.
On Android, must be set at creation.
View to use for this section footer.
Using this property and footerTitle
together is not supported. Use one or the other.
On Android, must be set at creation.
# headerTitle
Title of this section header.
Using this property and headerView
together is not supported. Use one or the other.
On Android, must be set at creation.
# headerView
View to use for this section header.
Using this property and headerTitle
together is not supported. Use one or the other.
On Android, must be set at creation.
In Alloy, you can use a <HeaderView>
element inside a <TableViewSection>
element:
<Alloy>
<TableView filterAttribute="title">
<SearchBar platform="android,ios"/>
<TableViewSection>
<HeaderView>
<View backgroundColor="#a00" height="50dp"/>
</HeaderView>
<FooterView>
<View backgroundColor="#0a0" height="50dp"/>
</FooterView>
<TableViewRow title="Row 1"/>
<TableViewRow title="Row 2"/>
<TableViewRow title="Row 3"/>
</TableViewSection>
</TableView>
</Alloy>
# lifecycleContainer
The Window or TabGroup whose Activity lifecycle should be triggered on the proxy.
If this property is set to a Window or TabGroup, then the corresponding Activity lifecycle event callbacks will also be called on the proxy. Proxies that require the activity lifecycle will need this property set to the appropriate containing Window or TabGroup.
# Methods
# add
Adds a table view row to this section.
Should be called before adding the section to a table. Calling add
on a section
that's already been added to a table does not update the table.
To add a row to a section after it's been added to a table, call one of the
TableView
methods, insertRowBefore,
insertRowAfter, or
appendRow.
On Android, it is possible to update a section by adding or removing rows and then
resetting the table view's data
property. However, this approach is not
portable and is not recommended.
Parameters
Name | Type | Description |
---|---|---|
row | Titanium.UI.TableViewRow | Row to add. |
Returns
- Type
- void
# addEventListener
Adds the specified callback as an event listener for the named event.
Parameters
Name | Type | Description |
---|---|---|
name | String | Name of the event. |
callback | Callback<Titanium.Event> | Callback function to invoke when the event is fired. |
Returns
- Type
- void
# applyProperties
Applies the properties to the proxy.
Properties are supplied as a dictionary. Each key-value pair in the object is applied to the proxy such that myproxy[key] = value.
Parameters
Name | Type | Description |
---|---|---|
props | Dictionary | A dictionary of properties to apply. |
Returns
- Type
- void
# fireEvent
Fires a synthesized event to any registered listeners.
Parameters
Name | Type | Description |
---|---|---|
name | String | Name of the event. |
event | Dictionary | A dictionary of keys and values to add to the Titanium.Event object sent to the listeners. |
Returns
- Type
- void
# remove
Removes a table view row from this section.
Should be called before a section is added to a table. Calling remove
on
a section that's already been added to a table may throw an exception.
To delete a row once the section is added to a table, use the TableView
deleteRow method.
On Android, it is possible to update a section by adding or removing rows and then
resetting the table view's data
property. However, this approach is not
portable and is not recommended.
Parameters
Name | Type | Description |
---|---|---|
row | Titanium.UI.TableViewRow | Row to remove. |
Returns
- Type
- void
# removeEventListener
Removes the specified callback as an event listener for the named event.
Multiple listeners can be registered for the same event, so the
callback
parameter is used to determine which listener to remove.
When adding a listener, you must save a reference to the callback function in order to remove the listener later:
var listener = function() { Ti.API.info("Event listener called."); }
window.addEventListener('click', listener);
To remove the listener, pass in a reference to the callback function:
window.removeEventListener('click', listener);
Parameters
Name | Type | Description |
---|---|---|
name | String | Name of the event. |
callback | Callback<Titanium.Event> | Callback function to remove. Must be the same function passed to |
Returns
- Type
- void
# rowAtIndex
Returns a row in this section.
Parameters
Name | Type | Description |
---|---|---|
index | Number | Section index of a row. |
