Background
The background lays the visual foundation of Panel and the application. For this background you can specify the appearance of the edge and the interior. The edge can be raised, lowered or flat, its width configurable. The interior can be transparent, filled with one or two colours. There are many different properties that determine how the two colours in a faded background combine.
Border
A panel can have a raised, lowered or flat border, its width configurable.
Client area
The client area, which is that area contained within the border, can also be filled with one or two colours. Once again there are many different properties that determine how the two colours in a faded background combine. The transparency of the client area can be adjusted so that the panel and client backgrounds combine to produce the final appearance. You can also combine Panels to produce interesting and attractive affects.
Corners
It is possible to specify the radius of the panel corners. The radius of each corner can be specified individually.
Images
Panel can display a foreground image, watermark and animated gif. The size and position of these images can be specified. The opacity of the watermark and animated gif may also be specified. Panel includes predefined images; you can also use your own.
Title
A title can be drawn on the panel border. The size, location, text and background of the title are configurable.
Some tips for colouring: Don't use too many colours, a handful is usually good enough. The colours should be easily distinguishable but also harmonious. Don't choose colours scattered all over the colour circle, rather select a few areas and use variations within those areas. Use the cool colours (blues and greens) for background and status; the warm colours (reds and yellows) for actions and operations.
Some tips for layout: Avoid sparse or cluttered layouts. Place important information or operations first or draw emphasis toward them. Minimise eye and cursor movement. Consider general use, the layout should be geared toward it. Use white space to show grouping. Try to maintain balance; the layout should not be skew or lopsided.
