Content Area

The content area contains everything else to be shown in the main window of your application - usually this simply means the document view, but if necessary, non-standard controls for the document may also appear. Your content area may also employ some of the advanced UI elements such as tree lists.

Tile the widgets for the content area in vertically and horizontally running groups. There should be no unfilled corners or blank areas. The dominant central part of the content area should be reserved for the document view. Non-standard controls should be arranged around this and may be hidden through menu entries and the panner widget.

The border between the document view and surrounding widgets should be set to zero. A frame for the document view is optional. The spacing of non-standard control widgets should be zero in most cases and have a standard margin where a clear division is required. Raised non-standard controls should use a one pixel width raised panel frame like the KDE toolbar and menubar widgets.

Implementation Note

The actual size of the standard margin depends on the style used on the desktop. You can obtain the standard margin by calling the KDialog::marginHint() method.
