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.

### removeTabAt(index)
Removes a specified tab in a tabpanel; can be based on a relation or relationless.
NOTE: In Servoy 4.x (and higher), the addTab function applies to relationless or related tabs in a tabpanel.
**Parameters**
* [Object](https://docs.servoy.com/reference/servoycore/dev-api/js-lib/object) **index** The index of the tab to remove.
**Returns:** [Boolean](https://docs.servoy.com/reference/servoycore/dev-api/js-lib/boolean) a boolean value indicating if tab was successfully removed

### setLocation(x, y)
Sets the location of an element. It takes as input the X (horizontal) and Y (vertical) coordinates - starting from the TOP LEFT side of the screen.\
Please note that location should not be altered at runtime when an element is anchored. Use the solutionModel in such a situation.
NOTE: getLocationX() can be used with getLocationY() to return the current location of an element; then use the X and Y coordinates with the setLocation function to set a new location. For Example:
//returns the X and Y coordinates\
var x = forms.company.elements.faxBtn.getLocationX();\
var y = forms.company.elements.faxBtn.getLocationY();
//sets the new location 10 px to the right; 10 px down from the current location\
forms.company.elements.faxBtn.setLocation(x+10,y+10);
**Parameters**
* [Number](https://docs.servoy.com/reference/servoycore/dev-api/js-lib/number) **x** the X coordinate of the element in pixels.
* [Number](https://docs.servoy.com/reference/servoycore/dev-api/js-lib/number) **y** the Y coordinate of the element in pixels.
**Returns:** void
**Sample**
```js
myElement.setLocation(200,200);

//sets the new size\
forms.company.elements.faxBtn.setSize(w,h);
