Type, Code and Description

Refer Common Controls.

Line

The Line controls consists of a pen style list, a pair of icon buttons labelled "Outlined or Not", On/Off respectively, control whether a line is drawn around the object at all and a colour select button.

Trans/Opaq

The transparency controls are only available when the selected 'Line style' has gaps in it e.g. a dashed line or a crosshatch fill pattern.

When one of these patterns is used you can set the transparency option to either Transparent or Opaque respectively. When transparent is selected, anything behind the object shows through the gaps. Otherwise, with opaque, everything behind the object is obscured and the object's background colour is drawn in the gaps instead.

Bk Color

You can only set the background colour of an object when the Transparency controls are enabled and set to Opaque. Clicking the coloured preview box opens the Color Select dialog where you can pick a preset colour or define your own. The background colour is then used to fill in the gaps of the line or fill pattern, instead of drawing whatever is behind the object.
