# Titanium.UI.TableViewRow
A table view row is an individual item in a table, organized into table view sections.
# Overview
Use the Titanium.UI.createTableViewRow method or <TableViewRow>
Alloy element to create
a table view row.
These may be explicitly added to Titanium.UI.TableViewSection objects, which are applied to a Titanium.UI.TableView. If a table section is not specified, one will be automatically created.
A row's contents can be as simple as a single line of text, or comprised of a completely customized layout of child views.
# Creating Table View Rows
Rows may be created using the properties directly available on the TableViewRow
object, to
achieve the following:
- Row title to display the text content in the row.
- Background color and background image.
- Images on the left and right sides of the row.
- System decorations, such as checkboxes.
Alternatively, custom layouts of multiple lines of text, different fonts, and additional
images or controls can be created by adding child views to the row. In this case, the row's
title
property should not be set.
As events automatically bubble/propogate to parent views, a listener may be placed on the table view to detect events fired from the rows. The benefit is that it is not necessary to explicitly create a listener for every individual row.
See the Titanium.UI.TableView description and examples section for more information about creating table rows.
# Platform Implementation Notes
The top
, left
and other positional parameters are not used for their usual purposes, because
the table view row is automatically positioned by its parent.
On Android, these properties are used to position the content (title) inside the row. For example,
setting top
to 20 moves the title down from the top of the row.
On iOS, these values have no effect.
Also, note that the selected text color, selectedColor
, can only be set on iOS.
On Android, the text color does not change when the row is selected.
# Row Swipe Gestures (Android and iOS)
A common requirement is to enable the user to interact with table rows using swipe gestures.
As this event is not available for the TableViewRow
object, it will not "bubble up" to the
TableView
, where a Titanium.UI.TableView.swipe is recognized.
A typical solution is to use a standard view as a container, or wrapper, for all each row's child views, because it recognizes Titanium.UI.View.swipe events and allows them to pass to the table. Each child view should have touch events disabled, so that the container view provides a reliable source for these events. Refer to the "Row Swipe Gestures" example for a demonstration.
For iOS, read the Titanium.UI.TableView regarding the interactions between edit modes and swipes.
# Examples
# Simple Table View Row example
Create a table view row containing a red square view.
var row = Titanium.UI.createTableViewRow();
var view = Titanium.UI.createView({
backgroundColor:'red',
width: 20, height: 20
});
row.add(view);
# Row Swipe Gestures
Create a table of rows. When a row is swiped, output its ID to the log.
var tableData = [];
var win = Ti.UI.createWindow({ backgroundColor: 'white' });
var table = Ti.UI.createTableView({ objName: 'table' });
for (var i = 0; i <= 20; i++){
var row = Ti.UI.createTableViewRow({
className: 'row',
objName: 'row',
touchEnabled: true,
height: 100
});
var enabledWrapperView = Ti.UI.createView({
backgroundColor:'#008FD5',
objName: 'enabledWrapperView',
rowID: i,
width: Ti.UI.FILL, height: '100%'
});
var disabledWrapperView = Ti.UI.createView({
backgroundColor:'#A2E0FF',
objName: 'disabledWrapperView',
touchEnabled: false,
width: 300, height: '80%'
});
enabledWrapperView.add(disabledWrapperView);
var label = Ti.UI.createLabel({
backgroundColor:'#313F48',
color: 'white',
objName: 'label',
text: i,
touchEnabled: false,
left: 0,
width: 200
});
disabledWrapperView.add(label);
row.add(enabledWrapperView);
tableData.push(row);
}
table.data = tableData;
table.addEventListener('swipe', function(e){
if (e.source && e.source.objName !== 'table'){
Ti.API.info('Row swiped: ' + e.source);
Ti.API.info('Row swiped: ' + e.source.objName);
Ti.API.info('Row ID : ' + e.source.rowID);
}
});
win.add(table);
win.open();
# Alloy XML Markup
Previous simple table view row example as an Alloy view.
<Alloy>
<TableViewRow id="row">
<View id="view" backgroundColor="red" width="20" height="20"/>
</TableViewRow>
</Alloy>
# Properties
# accessibilityLabel
A succint label associated with the table row for the device's accessibility service.
See accessibilityLabel description.
# backgroundSelectedColor
Background color to render when the row is selected, as a color name or hex triplet.
For information about color values, see the "Colors" section of Titanium.UI.
# backgroundSelectedImage
Background image to render when the row is selected.
For normal views, the selected background is only used if focusable
is true
.
If backgroundSelectedImage
is undefined, and the normal background image backgroundImage
is set
the normal image is used when this view is selected.
# className
Class name for the row.
A class name represents a unique row layout.
A table view row must have a unique class name if the row layout is unique. However, use the same name for rows that have the same structural layout (even if the content is different) to provide maximum rendering performance.
For example, if some rows include images and some rows do not, you would have two class names, one for image rows and one for plain rows.
This property exists on iOS, but is ignored.
# color
Default text color of the row when not selected, as a color name or hex triplet.
For information about color values, see the "Colors" section of Titanium.UI.
On Android, the default text color is black if the background color is closer to white
otherwise the default text color is white also selectedColor
is not supported
so the text is always displayed in this color.
# deleteButtonTitle
Text to display on the delete button when editable is enabled
When editable is enabled on the TableViewRow, use this property to change the title of the delete button.
# editable
Determines the rows' editable behavior, which allows them to be deleted by the user when the
table is in editing
or moving
mode.
If this property is not explicitly set, it will return undefined
and the row's editable
behavior will be determined by its parent table's editable
property.
See the Titanium.UI.TableView description section for a full explanation of the TableView's
row editing
and moving
modes.
If you want to change the title of the delete button, use the [deleteButtonTitle](Titanium.UI.TableViewRow.deleteButtonTitle] property
Default: undefined
# footer DEPRECATED
DEPRECATED SINCE 10.0.0
Use the footerTitle property instead.
The footer title of the row.
The footer
property is used to assign a footer title to a row. It has the same effect as setting
the footerTitle
property of a Titanium.UI.TableViewSection.
# footerTitle
The footer title of the row.
The footerTitle
property is used to assign a footer title to a row. It has the same effect as setting
the footerTitle
property of a Titanium.UI.TableViewSection.
# hasCheck
Determines whether a system-provided checkmark is displayed on the right-hand side of the row.
Default: false
# hasChild
Determines whether a system-provided arrow is displayed on the right-hand side of the row.
The hasChild
flag is used to indicate to the user that clicking on the row displays more
detailed information.
On iOS, this is specifically used when clicking on the row navigates to the next table view in a heirarchy of table views.
Default: false
# hasDetail
Determines whether a system-provided detail disclosure button is displayed on the right-hand side of the row.
The hasDetail
flag is used to indicate to the user that more details are
available on the row.
Specifically on iOS the detail disclosure button indicates that clicking on the row results in a detail view of that item.
The detail
property in the click event is set to true
if the click occurred on
the detail button itself, false
if the click occurs anywhere else in the row.
For rows that have hasDetail
set to false, the detail
flag is always false
.
Default: false
# header DEPRECATED
DEPRECATED SINCE 10.0.0
Use the headerTitle property instead.
The header title of the row.
The header
property is used to assign a header title to a row. It has the same effect as setting
the headerTitle
property of a Titanium.UI.TableViewSection.
# headerTitle
The header title of the row.
The headerTitle
property is used to assign a header title to a row. It has the same effect as setting
the headerTitle
property of a Titanium.UI.TableViewSection.
# indentionLevel
Indention level for the row.
Indentation values greater than 0 indent the row text.
Default: 0
# leftImage
Image to render in the left image area of the row, specified as a local path or URL.
# moveable
Determines the rows' moveable behavior, which allows them to be re-ordered by the user when
the table is in editing
or moving
mode.
If this property is not explicitly set, it will return undefined
and the row's moveable
behavior will be determined by its parent table's moveable
property.
See the Titanium.UI.TableView description section for a full explanation of the TableView's
row editing
and moving
modes.
Default: undefined
# opacity
Opacity of this view, from 0.0 (transparent) to 1.0 (opaque). Defaults to 1.0 (opaque).
To set the opacity of a row on iOS, specify an aRGB value with the <Titanium.UI.TableViewRow.backgroundColor> property.
# rightImage
Image to render in the right image area of the row, specified as a local path or URL.
# selectedBackgroundColor DEPRECATED
DEPRECATED SINCE 10.0.0
This property has been deprecated in favor of backgroundSelectedColor.
Background color to render when the row is selected, as a color name or hex triplet.
For information about color values, see the "Colors" section of Titanium.UI.
# selectedBackgroundImage DEPRECATED
DEPRECATED SINCE 10.0.0
This property has been deprecated in favor of backgroundSelectedImage.
Background image to render when the row is selected.
# selectedColor
Color of the row text when the row is selected, as a color name or hex triplet.
For information about color values, see the "Colors" section of Titanium.UI.
# selectionStyle
Selection style constant to control the selection color.
Specify one of the constants from <Titanium.UI.SELECTION_STYLE_*>.
# title
Text to display on the row.
Do not specify if using views as children of the row.
# Events
# click
Fired when a table row is clicked by the user.
There is a subtle difference between singletap and click events.
A singletap event is generated when the user taps the screen briefly without moving their finger. This gesture will also generate a click event.
However, a click event can also be generated when the user touches, moves their finger, and then removes it from the screen.
On Android, a click event can also be generated by a trackball click.
