Properties 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

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);

Returns String

Sample

// This property can be used on all types of components.
// 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.

Returns CSSPosition

Sample

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

dataProviderID

The dataprovider of the component.

Returns 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.

Returns 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

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.

Returns 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);

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

Sample

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.

Returns 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.

Returns 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);

labelOne.mnemonic = 'O';

margin

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

Returns 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.

Returns 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.background = 'yellow';	
smallLabelWithBigImageCrop.mediaOptions = SM_MEDIAOPTION.CROP;
// Put the small image in several big labels, with different media options.
var bigLabelWithSmallImageEnlargeKeepAspect = form.newLabel('', 10, 70, 200, 100);
bigLabelWithSmallImageEnlargeKeepAspect.imageMedia = smallImage;
bigLabelWithSmallImageEnlargeKeepAspect.background = 'yellow';

var bigLabelWithSmallImageEnlargeNoAspect = form.newLabel('', 10, 180, 200, 100);
bigLabelWithSmallImageEnlargeNoAspect.imageMedia = smallImage;
bigLabelWithSmallImageEnlargeNoAspect.background = 'yellow';
bigLabelWithSmallImageEnlargeNoAspect.mediaOptions = SM_MEDIAOPTION.ENLARGE;

bigLabelWithSmallImageCrop.imageMedia = smallImage;
bigLabelWithSmallImageCrop.background = 'yellow';
bigLabelWithSmallImageCrop.mediaOptions = SM_MEDIAOPTION.CROP; // This does not do any cropping actually if the label is larger than the image.

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

Sample

var m = form.newMethod('function onClick() { application.output("I was clicked."); }');
var btn = form.newButton('I am a button', 10, 40, 200, 20, m);
btn.mnemonic = 'B'; // When ALT-B is pressed the mouse will respond as if clicked.
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'; // When ALT-O is pressed the focus will move to fieldOne.

name

var label = form.newLabel('Label', 10, 10, 150, 150);
label.name = 'myLabel'; // Give a name to the component.
forms['someForm'].controller.show()
// Now use the name to access the component.
forms['someForm'].elements['myLabel'].text = 'Updated text';
