Property Details
anchors

Enables a component to stick to a specific side of form and/or to
grow or shrink when a window is resized.

If opposite anchors are activated then the component with grow or
shrink with the window. For example if Top and Bottom are activated,
then the component will grow/shrink when the window is vertically
resized. If Left and Right are activated then the component
will grow/shrink when the window is horizontally resized.

If opposite anchors are not activated, then the component will
keep a constant distance from the sides of the window which
correspond to the activated anchors.
Returns
Number
background
The background color of the component.
Returns
String
borderType
The type, color and style of border of the component.
Returns
String
dataProvider
The dataprovider of the component.
Returns
String
displaysTags

Flag that enables or disables merging of data inside components using tags (placeholders).
Tags (or placeholders) are words surrounded by %%on each side. There are data tags and
standard tags. Data tags consist in names of dataproviders surrounded by%%. Standard tags
are a set of predefined tags that are made available by the system.

See the "Merging data" section for more details about tags.

The default value of this flag is "false", that is merging of data is disabled by default.
Returns
Boolean
fontType
The font type of the component.
Returns
String
foreground
The foreground color of the component.
Returns
String
horizontalAlignment

Horizontal alignment of the text inside the component. Can be one of
LEFT, CENTER or RIGHT.

Note that this property does not refer to the horizontal alignment
of the component inside the form.
Returns
Number
imageMedia
The image Media object that should be displayed inside the component.
Returns
Number
labelFor
Some components can be set to be labels of other components. This is useful in
two situations. In table view mode it is used for constructing the header of the
table. In record view mode, by setting mnemonics on the label, keyboard shortcuts
can be used to set the focus to fields.
Returns
String
location
The x and y position of the component, in pixels, separated by a comma.
Returns
String
margin
The margins of the component. They are specified in this order,
separated by commas: top, right, bottom, left.
Returns
String
mediaOptions

Options to scale the image Media object that is displayed inside the component.
Can be set to one or a combination of CROP, REDUCE, ENLARGE and KEEPASPECT.

REDUCE will scale down the image if the component is smaller than the image.
REDUCE combined with KEEPASPECT will reduce the image, but keep its aspect ratio.
This is useful when the component has other proportions than the image.

ENLARGE will scale up the image if the component is larger than the image.
ENLARGE combined with KEEPASPECT will scale up the image while keeping its aspect ratio.

CROP will leave the image at its original size. If the component is smaller than
the image this will result in only a part of the image showing up.
Returns
Number
mnemonic

The keyboard shortcut that activates this component. A letter must be specified,
and the actual shortcut will be combination of ALT + the specified letter.

This property can be used in two ways. Normally the keyboard shortcut activates
the onClick event of the component. But if the "labelFor" property is set for the
component, then the keyboard shortcut will move the focus to the component whose
label this component is.
Returns
String
name
The name of the component. Through this name it can also accessed in methods.
Returns
String
printSliding
Enables an element to resize based on its content and/or move when printing.
The component can move horizontally or vertically and can grow or shrink in
height and width, based on its content and the content of neighboring
components.
Returns
Number
printable

Flag that tells if the component should be printed or not when the form is printed.

By default components are printable.
Returns
Boolean
rolloverCursor
The cursor that is shown as the mouse is rolled over the component.
Possible options are DEFAULT and HAND.
Returns
Number
rolloverImageMedia
The roll over image Media object used. When the mouse is moved over the component,
this image Media will be displayed. When the mouse is moved out of the component,
whatever text or image was being initially displayed will be restored.
Returns
Number
rotation
The rotation of the element. You can choose 0, 90, 180, or 270 and the label is rotated accordingly.
This property also applies to buttons and images.
Returns
Number
showClick
When set, the element will show the clicked state when selected.
Applies to labels and buttons and images only.
Returns
Boolean
showFocus

When set the text of an element will showfocus when selected.
Applies to labels and buttons only.
The text property for the element MUST be filled in first.

on the operating system being used and the selected LAF.
Returns
Boolean
size
The width and height (in pixels), separated by a comma.
Returns
String
styleClass

The name of the style class that should be applied to this component.

When defining style classes for specific component types, their names
must be prefixed according to the type of the component. For example
in order to define a class names 'fancy' for fields, in the style
definition the class must be named 'field.fancy'. If it would be
intended for labels, then it would be named 'label.fancy'. When specifying
the class name for a component, the prefix is dropped however. Thus the
field or the label will have its styleClass property set to 'fancy' only.
Returns
String
tabSeq
An index that specifies the position of the component in the tab sequence. The components
are put into the tab sequence in increasing order of this property. A value of 0 means
to use the default mechanism of building the tab sequence (based on their location on the form).
A value of -2 means to remove the component from the tab sequence.
Returns
Number
