Margin-Width
This property allows you to set or retrieve the amount of space between the four borders of the Entry-Field control and the text inside the control. The property is a list of four values that specify the width in pixels of the top, left, bottom and right margin respectively.
Setting the property to -1 resets the margins.
Passing less than four values assumes that the remaining values are the default values in the current Look & Feel.
When the Entry-Field control doesn't have the Multiline style, top and bottom margins are ignored, regardless of the value of the Lines property.
When the Entry-Field control has a bitmap, the left margin is ignored.
When the Entry-Field control has a trailing bitmap, the right margin is ignored.
The margin width set by this property might be influenced by the layout provided by the iscobol.gui.native_style (boolean) * setting for the control.
 
Example - Define an entry-field control with 3 pixels of padding space on the left and on the right of the text
screen section.
