This component is used to create a widget to display an integer value in the GUI, where the value is specified by the data input [In]data . The position, dimensions, colour and transparency of the widget are specified in the widget properties in the GUI Builder, LGB. In addition the data inputs [In]off.x and [In]off.y can be used to change the position of the widget by specifying the offset from its original position in the x and y axis respectively. The data inputs href="#[In]off.wid"> [In]off.wid and [In]off.ht can be used to specify an offset in the width and the height of the widget from the original dimensions and [In]alpha can be used to change the alpha value of the transparency of the widget. Note that if the property Maintain Aspect Ratio is set to TRUE then changes to the widget width using the data input [In]off.wid also change the height to maintain the aspect ratio and changes to height using the data input [In]off.ht are ignored.

The input event [In]create will allocate the memory for the widget and [In]destroy will deallocate the memory. When the input event href="#[In]create"> [In]create is triggered, data is presented to outputs [Out]abs x , [Out]abs y , [Out]wid and [Out]ht , describing the absolute position and dimensions of the widget as created.

The input events [In]show and [In]hide will show and hide the widget. The state of the widget as shown or hidden is persistent, so that if href="#[In]show"> [In]show is asserted before [In]create , the widget will be shown when [In]create is asserted.

When the input event [In]update is asserted, the values presented to the inputs [In]off.x , [In]off.y , [In]off.wid , [In]off.ht and [In]alpha will be used to update the widget properties. Data is presented to outputs [Out]abs x , [Out]abs y , [Out]wid and [Out]ht , describing the updated absolute position and dimensions of the widget. It should be noted that the data inputs [In]off.x and [In]off.y specify the offset in the x and y axis from its original position and the data outputs [Out]abs x and [Out]abs y refer to the absolute x and y coordinates of the widget in reference to the viewport. This allows the data output to be used to detect if widgets are overlapping in the GUI.

name type default min. max. description
Widget Tag String None widget widget tag Name of the widget as displayed in the GUI builder.
Widget-Group Selectable None default widget group Group that the widget belongs to in the GUI builder.
Maintain Aspect Ratio Boolean 0 - - Maintains aspect ratio of widget when width is changed and ignores changes in height if TRUE, allows width and height to be altered independently if FALSE.
Register Click Disregarding Z-Order Boolean 0 - - Allows a widget to register a mouse click event when it is hidden behind another widget if TRUE, the widget only registers mouse clicks if the widget is visible at the coords that the mouse click occurs at if FALSE.
