In some forms of the cash register application, there are buttons for selecting an order and a visit. The appearance of the buttons can be changed using a special editor (called from the Model property of the Buttons with Orders object of the Forms directory), which is described in this chapter.
Button form editor window: 
The button layout is a line of the "Order Button" object. You can add fields and images to the line using the Add Field and Add Image commands of the pop-up menu called from the line area, respectively.
For field-type objects, in the Field Name property, select the object property from the list that will be presented in the field. For picture-type objects, in the Picture property, select the image that will be displayed in this area.
A new field is added to the upper left corner of the line, then it is dragged to the desired location and the dimensions are set by dragging the object's border points or entering values in the Left and Top properties (Position group).
You can select an object using the mouse cursor or selecting a needed line from the list.
The Fields have the following properties:
