## 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](https://docs.servoy.com/reference/servoycore/dev-api/js-lib/number)

**Sample**

```js
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);
strechAllDirectionsLabel.background = 'red';
strechAllDirectionsLabel.anchors = SM_ANCHOR.ALL;
var strechVerticallyLabel = form.newLabel('Strech vertically', 10, 10, 190, 280);
strechVerticallyLabel.background = 'green';
strechVerticallyLabel.anchors = SM_ANCHOR.WEST | SM_ANCHOR.NORTH | SM_ANCHOR.SOUTH;
var strechHorizontallyLabel = form.newLabel('Strech horizontally', 10, 10, 380, 140);
strechHorizontallyLabel.background = 'blue';
strechHorizontallyLabel.anchors = SM_ANCHOR.NORTH | SM_ANCHOR.WEST | SM_ANCHOR.EAST;
var stickToTopLeftCornerLabel = form.newLabel('Stick to top-left corner', 10, 10, 200, 100);
stickToTopLeftCornerLabel.background = 'orange';
stickToTopLeftCornerLabel.anchors = SM_ANCHOR.NORTH | SM_ANCHOR.WEST; // This is equivalent to SM_ANCHOR.DEFAULT
var stickToBottomRightCornerLabel = form.newLabel('Stick to bottom-right corner', 190, 190, 200, 100);
stickToBottomRightCornerLabel.background = 'pink';
stickToBottomRightCornerLabel.anchors = SM_ANCHOR.SOUTH | SM_ANCHOR.EAST;
```

### background

The background color of the component.

**Type**\
[String](https://docs.servoy.com/reference/servoycore/dev-api/js-lib/string)

**Sample**

```js
// 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);
redField.background = '#FF0000'; // Use RGB codes for colors.
```

### borderType

The type, color and style of border of the component.

**Type**\
[String](https://docs.servoy.com/reference/servoycore/dev-api/js-lib/string)

**Sample**

```js
//HINT: To know exactly the notation of this property set it in the designer and then read it once out through the solution model.
var field = form.newField('my_table_text', JSField.TEXT_FIELD, 10, 10, 100, 20);
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](https://docs.servoy.com/reference/servoycore/dev-api/application/cssposition)

**Sample**

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

### dataProviderID

The dataprovider of the component.

**Type**\
[String](https://docs.servoy.com/reference/servoycore/dev-api/js-lib/string)

**Sample**

```js
// 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](https://docs.servoy.com/reference/servoycore/dev-api/js-lib/boolean)

**Sample**

```js

```

### 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](https://docs.servoy.com/reference/servoycore/dev-api/js-lib/string)

**Sample**

```js
var labelOne = form.newLabel('Label One', 10, 10, 100, 20);

### 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.

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';
bigLabelWithSmallImageEnlargeKeepAspect.mediaOptions = SM_MEDIAOPTION.ENLARGE | SM_MEDIAOPTION.KEEPASPECT;

// By default the label does not visually react to clicks, but we can enable this.
// Basically the label will now behave as a button does.
label.showClick = true;
// Create a button with the same method attached to its onClick event.
var btn = form.newButton('And I am a button', 10, 40, 200, 20, m);

### 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.

// Create three fields. Based on how they are placed, by default they will come one
// after another in the tab sequence.
var fieldOne = form.newField('parent_table_id', JSField.TEXT_FIELD, 10, 10, 100, 20);
var fieldTwo = form.newField('parent_table_text', JSField.TEXT_FIELD, 10, 40, 100, 20);
