Properties Detailed

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.

Type Number

Sample

var form = solutionModel.newForm('mediaForm', 'db:/example_data/parent_table', null, false, 400, 300);
var strechAllDirectionsLabel = form.newLabel('Strech all directions', 10, 10, 380, 280);

stickToTopLeftCornerLabel.background = 'orange';
stickToTopLeftCornerLabel.anchors = SM_ANCHOR.NORTH | SM_ANCHOR.WEST; // This is equivalent to SM_ANCHOR.DEFAULT

// Here it is illustrated only for labels and fields.
var greenLabel = form.newLabel('Green',10,10,100,50);
greenLabel.background = 'green'; // Use generic names for colors.
var redField = form.newField('parent_table_text',JSField.TEXT_FIELD,10,110,100,30);

field.borderType = solutionModel.createLineBorder(1,'#ff0000');

cssPosition

CSS position is a replacement for anchoring system making it more intuitive to place a component. CSS position should be set on form, an absolute position form can either work with anchoring or with css position. This is only working in NGClient.

Type CSSPosition

Sample

var label = form.newLabel('Label', -1);
label.cssPosition.r("10").b("10").w("20%").h("30px")

dataProviderID

Type String

Sample

// Normally the dataprovider is specified when a component is created.
var field = form.newField('parent_table_text', JSField.TEXT_FIELD, 10, 40, 100, 20);
// But it can be modified later if needed.
field.dataProviderID = 'parent_table_id';

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.

Type Boolean

Sample

var label = form.newLabel('You are viewing record no. %%parent_table_id%%. You are running on server %%serverURL%%.', 
					10, 10, 600, 100);
label.displaysTags = true;

enabled

The enable state of the component, default true.

Type Boolean

Sample

var form = solutionModel.newForm('printForm', 'db:/example_data/parent_table', null, false, 400, 300);

Type String

Sample

var label = form.newLabel('Text here', 10, 50, 100, 20);
label.fontType = solutionModel.createFont('Times New Roman',1,14);

foreground

The foreground color of the component.

Type String

Sample

// This property can be used on all types of components.
// Here it is illustrated only for labels and fields.
var labelWithBlueText = form.newLabel('Blue text', 10, 10, 100, 30);
labelWithBlueText.foreground = 'blue'; // Use generic names for colors.
var fieldWithYellowText = form.newField('parent_table_text', JSField.TEXT_FIELD, 10, 50, 100, 20);
fieldWithYellowText.foreground = '#FFFF00'; // Use RGB codes for colors.

formIndex

The Z index of this component. If two components overlap, then the component with higher Z index is displayed above the component with lower Z index.

Type Number

Sample

var labelBelow = form.newLabel('Green', 10, 10, 100, 50);
labelBelow.background = 'green';
labelBelow.formIndex = 10;
var fieldAbove = form.newField('parent_table_text', JSField.TEXT_FIELD, 10, 10, 100, 30);
fieldAbove.background = '#FF0000';
fieldAbove.formIndex = 20;

format

The format that should be applied when displaying data(using dataProviderID) in the label/button. Some examples are "#%", "dd-MM-yyyy", "MM-dd-yyyy", etc.

Type String

Sample

var label = form.newLabel('', 10, 10, 100, 100);
label.format = '$#.00';

groupID

A String representing a group ID for this component. If several components have the same group ID then they belong to the same group of components. Using the group itself, all components can be disabled/enabled or made invisible/visible. The group id should be a javascript compatible identifier to allow access of the group in scripting.

Type String

Sample

var form = solutionModel.newForm('someForm', 'db:/example_data/parent_table', null, false, 400, 300);
var label = form.newLabel('Green', 10, 10, 100, 20);
var field = form.newField('parent_table_text', JSField.TEXT_FIELD, 10, 40, 100, 20);
label.groupID = 'someGroup';
field.groupID = 'someGroup';
forms['someForm'].elements.someGroup.enabled = false;

height

The height in pixels of the component.

Type Number

Sample

var field = form.newField('parent_table_text', JSField.TEXT_FIELD, 10, 10, 100, 20);
application.output('original width: ' + field.width);
application.output('original height: ' + field.height);
field.width = 200;
field.height = 100;
application.output('modified width: ' + field.width);
application.output('modified height: ' + field.height);

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.

Type Number

Sample

var leftAlignedLabel = form.newLabel('LEFT', 10, 10, 300, 20);
leftAlignedLabel.horizontalAlignment = SM_ALIGNMENT.LEFT;
var hCenteredLabel = form.newLabel('CENTER', 10, 40, 300, 20);
hCenteredLabel.horizontalAlignment = SM_ALIGNMENT.CENTER;
var rightAlignedLabel = form.newLabel('RIGHT', 10, 70, 300, 20);
rightAlignedLabel.horizontalAlignment = SM_ALIGNMENT.RIGHT;

imageMedia

The image Media object that should be displayed inside the component.

Type JSMedia

Sample

var ballBytes = plugins.file.readFile('d:/ball.jpg');
var ballImage = solutionModel.newMedia('ball.jpg', ballBytes);
var label = form.newLabel('', 10, 10, 100, 100);
label.imageMedia = ballImage;

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.

Type String

Sample

var labelOne = form.newLabel('Label One', 10, 10, 100, 20);
var fieldOne = form.newField('parent_table_id', JSField.TEXT_FIELD, 120, 10, 100, 20);
fieldOne.name = 'fieldOne';
labelOne.labelFor = 'fieldOne';
labelOne.mnemonic = 'O';

margin

The margins of the component. They are specified in this order, separated by commas: top, left, bottom, right.

Type String

Sample

var label = form.newLabel('Label', 10, 10, 150, 150);
label.background = 'yellow';
label.margin = '10,20,30,40';

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.

Type Number

Sample

// Load two images, a big one and a small one.
var bigBytes = plugins.file.readFile('d:/big.jpg');
var bigImage = solutionModel.newMedia('big.jpg', bigBytes);
var smallBytes = plugins.file.readFile('d:/small.jpg');
var smallImage = solutionModel.newMedia('small.jpg', smallBytes);
// Put the big image in several small labels, with different media options.
var smallLabelWithBigImageReduceKeepAspect = form.newLabel('', 10, 10, 50, 50);
smallLabelWithBigImageReduceKeepAspect.imageMedia = bigImage;
smallLabelWithBigImageReduceKeepAspect.background = 'yellow';	
smallLabelWithBigImageReduceKeepAspect.mediaOptions = SM_MEDIAOPTION.REDUCE | SM_MEDIAOPTION.KEEPASPECT;
var smallLabelWithBigImageReduceNoAspect = form.newLabel('', 70, 10, 50, 50);
smallLabelWithBigImageReduceNoAspect.imageMedia = bigImage;
smallLabelWithBigImageReduceNoAspect.background = 'yellow';	
smallLabelWithBigImageReduceNoAspect.mediaOptions = SM_MEDIAOPTION.REDUCE;
var smallLabelWithBigImageCrop = form.newLabel('', 130, 10, 50, 50);
smallLabelWithBigImageCrop.imageMedia = bigImage;
