absPos() Get the absolute position (top/left) of this box on the page. Note: You can only use this function if the HTML content of the page is fully rendered. |
|
| public |
addClass(cls) Add a CSS class name to the class list of the HTML element associated with the box. |
|
| public |
addListener(type, listener) Add/register a listener function. This way it is possible to register more than one listener function on one target. |
|
| public | SUI.Border |
border(b) Get or set the border definition of the box. |
| public | int |
bottom(b) Get or set the bottom of the box. |
| public |
callListener(type) Call a listener function. Execute the default and additional listener functions. Note: the framework should not execute the default listeners directly but always through this method to ensure the execution of additional listener functions. |
|
| public | int |
Get the client height of the box. The client height is the height of the box minus the top and bottom border and padding width. |
| public | int |
Get the client width of the box. The client width is the width of the box minus the left and right border and padding width. |
| public |
display() Display RGB control. Set the size and position of the bar and crosshair. |

| public |
draw() Draw the box on the screen.

el() Get the HTML element node of the box. |
| public | int |
height(h) Get or set the height of the box. |
| public |
layOut() Lay out the box. Calculate the position of the box and its contents. The layOut function of a simple box does nothing, but it's important for more complex objects extended from SUI.Box. The layOut mechanism will set the size and position of the child boxes of the box based on the on the available space and within the restrictions of the box's minimum and maximum width and height. So the job of the overridden layOut method is to recalculate the size and position of all the child elements of the box when the layout manager sets the size of the box and calls the box's layOut method. |

| public | int |
left(l) Get or set the left of the box. |
| public | int |

| public | SUI.Padding |
padding(p) Get or set the padding definition of the box. |
| public | SUI.Box |
parent(p) Get or set the parent box of the box. When setting the parent the box's element node will be appended to the parent box's HTML element node. |

|
| public | int |

|
| public | int |
