 === XButton ===
+XButton is a Push Button with built in Light indicator. Light is mostly used to show a current state of CNC controller input, output pin, CNC global variable register value etc.
+A XButton XML definition example is shown below
+<code XML>
+<gitem where="x-mill"
+ xattr="3;3;16;16;led;red;round"
+ address="outputs" number="#OUTPUT_SPINDLE".
+ position="720;10" width="70" height="70"
+ image="M/button-m03" action="plc-run:M03/#5524"
+ type="xbutton" />
+</code>
+Attributes description
+  * **where** - parent widget name the button placed to
+  * **position** - X and Y position of the button inside a parent widget
+  * **width** - button width in pixels
+  * **height** - button height in pixels
+  * **type** - type definitionof the item (should be type="button")
+  * **image** - a image (icon) file in SVG format for the button
+  * **action** - action for the button (which procedure will be executed if event triggered)
+  * **event** - event type the button is sensitive to. Event can be
+    * **pressed** - action is executed if the button pressed
+    * **released** - action is executed if the button released
+    * **both** - there are separate actions (";" semicolon separated) for **pressed** and **released** events
+  * **skinbase** - besides the Image file for each button there is a common **skin** SVG file for all the buttons. For selected buttons skin file can be redefined with **skinbase** attribute. This SVG file will be used as a bottom layer for the button image.
+  * **xattr** - defines light positionm size and attributes - semicolon separated
+      * X,Y position of the led/light inside the button
+      * width and height of the led
+      * type of light (actually this field is always "led", reserved for future options)
+      * shape of the standard led light. A standard shape can be "round" and "rect"
+  * **address** - defines CNC controller hardware the light attached to
+      * "inputs" - the light attached to input pin
+      * "outputs" - the light attached to output pin
+      * "number" - defines pin number the light attached to. A number can be assigned directly, for example \\ number="0" for pin #0 \\ number="15" for ipn #15 \\ or through pin definition file used in Hardware PLC - "pins.h". In this case sign "#" and the pin name defined in "pins.h" should be instead of pin number. For example \\ **number="#OUTPUT_SPINDLE"** \\ and "pins.h should contain this name definition, for example <code C>#define OUTPUT_SPINDLE 7</code>
