Properties Detailed

bgcolor

Gets or sets the background color of a field. The color has to be set using the hexadecimal RGB value as used in HTML. It only returns it's correct value if it was explicitly set.

Type String

Sample

//sets the background color of the field
myElement.bgcolor = "#FFFFFF";
//gets the background color of the field
var c = myElement.bgcolor;

border

Gets or sets the border attribute(s) of a specified element.

The border attributes:

borderType - EmptyBorder, EtchedBorder, BevelBorder, LineBorder, TitleBorder, MatteBorder, SpecialMatteBorder. size - (numeric value) for: bottom, left, right, top. color - (hexadecimal value) for: bottom, left, right, top. dash pattern - (numeric value) for selected side(s). rounding radius - (numeric value) for selected side(s).

It only returns it's correct value if it was explicitly set.

NOTE: Use the same value(s) and order of attribute(s) from the element design time property "borderType".

Type String

Sample

//sets the border type to "LineBorder"
//sets a 1 px line width for the bottom and left side of the border
//sets the hexadecimal color of the border to "#ccffcc"
myElement.border = 'LineBorder,1,#ccffcc';

editable

Gets or sets the editable/read-only state of a field; true - editable; false - read-only.

NOTE the "!" operator can be used to invert the editable state.

Type Boolean

Sample

var currentState = myElement.editable;
myElement.editable = !currentState;

enabled

Gets or sets the enabled state of a specified field, also known as "grayed". true - enabled; false - not enabled; ! - the enabled state is inverted (the opposite).

NOTE: A disabled element cannot be selected by clicking the element (or by pressing the TAB key even if this option is supported by the operating system).

NOTE: A label or button element will not disable if the "displayType" design time property for a field is set to HTML_AREA.

NOTE: The disabled "grayed" color is dependent on the LAF set in the Servoy Client Application Preferences. For more information see Preferences: Look And Feel in the Servoy Developer User's Guide.

Type Boolean

Sample

//gets the enabled state of the field
var currState = myElement.enabled;

//sets the enabled state of the field
myElement.enabled = !currentState;

fgcolor

Gets or sets the foreground color of a field. The color has to be set using the hexadecimal RGB value as used in HTML. It only returns it's correct value if it was explicitly set.

Type String

Sample

//sets the foreground color of the field
myElement.fgcolor = "#000000";

//gets the foreground color of the field
var c = myElement.fgcolor;

font

Gets or sets the font name, style, and size of an element.

font name - the name of the font family. style - the type of the font. (plain = 0; bold = 1; italic = 2; bold-italic = 3). size - the size of the font (in points).

It only returns it's correct value if it was explicitly set.

Type String

Sample

myElement.font = 'Tahoma,1,11';

format

Gets or sets the display formatting of an element for number and text values; does not affect the actual value stored in the database column.

There are different options for the different dataprovider types that are assigned to this field. For Integer fields, there is a display and an edit format, using http://docs.oracle.com/javase/7/docs/api/java/text/DecimalFormat.html and the max (string) length can be set. For Text/String fields, there are options to force uppercase,lowercase or only numbers. Or a mask can be set that restrict the input the pattern chars can be found here: http://docs.oracle.com/javase/7/docs/api/javax/swing/text/MaskFormatter.html A mask can have a placehoder (what is shown when there is no data) and if the data must be stored raw (without literals of the mask). A max text length can also be set to force the max text length input, this doesn't work on mask because that max length is controlled with the mask. For Date fields a display and edit format can be set by using a pattern from here: http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html, you can also say this must behave like a mask (the edit format) A mask only works with when the edit format is exactly that mask (1 char is 1 number/char), because for example MM then only 2 numbers are allowed MMM that displays the month as a string is not supported as a mask. Some examples are "dd-MM-yyyy", "MM-dd-yyyy", etc. The format property is also used to set the UI Converter, this means that you can convert the value object to something else before it gets set into the field, this can also result in a type change of the data. So a string in scripting/db is converted to a integer in the ui, then you have to set an integer format. It only returns it's correct value if it was explicitly set, otherwise null.

Type String

Sample

//sets the display formatting of the field
myElement.format = '###';

//gets the display formatting of the field
var format = myElement.format;

readOnly

Gets or sets the editable/read-only state of a field; true - read-only; false - editable; ! - the editable/read-only state is inverted (the opposite).

NOTE: A field set as read-only can be selected by clicking (or pressing the TAB key if this option is supported by the operating system) and the field data can be copied.

Type Boolean

Sample

//gets the editable/read-only state of the field
var currentState = myElement.readOnly;

//sets the editable/read-only state of the field
myElement.readOnly = !currentState;

titleText

Gets or sets the title text.

Type String

Sample

var titleText = myElement.titleText;

toolTipText

Gets or sets the tool tip text of an element; text displays when the mouse cursor hovers over an element.

NOTE: HTML should be used for multi-line tooltips; you can also use any valid HTML tags to format tooltip text.

Type String

Sample

//gets the tooltip text of the element
var toolTip = myElement.toolTipText;

//sets the tooltip text of the element
myElement.toolTipText = "New tip";
myElement.toolTipText = "<html>This includes <b>bolded text</b> and <font color='blue'>BLUE</font> text as well.";

transparent

Gets or sets the transparency of an element; true - transparent; false - not transparent.

NOTE: transparency can be inverted using ! operator: elements.elementName.transparent = !elements.elementName.transparent;

NOTE: transparency will be mostly used for background color, a transparent element will receive the background of the element "beneath" it, a non transparent one will use its own background color

Type Boolean

Sample

//gets the transparency of the element
var currentState = myElement.transparent;

//sets the transparency of the element
myElement.transparent = !currentState;

visible

Gets or sets the visibility of an element; true - visible; false - not visible; ! - the visibility state is inverted (the opposite).

NOTE: The visibility of an element is not persistent; the state of visibility only applies to the current user in his/her current session.

Type Boolean

Sample

//sets the element as visible
forms.company.elements.faxBtn.visible = true;

//gets the visibility of the element
var currentState = forms.company.elements.faxBtn.visible;

//sets the element as not visible when the current state is visible
forms.company.elements.faxBtn.visible = !currentState;

Should receive a dataset parameter, first column is for display values, second column (optional) is for real values.

NOTE: if you modify values for checkbox/radio field, note that having one value in valuelist is a special case, so switching between one value and 0/multiple values after form is created may have side effects

Parameters

• Object value first column is display value, second column is real value

Returns: void

Sample

var dataset = databaseManager.createEmptyDataSet(0,new Array('display_values','optional_real_values'));
