classdef BoxPanel < uiextras.CardPanel & uiextras.DecoratedPanel
%BoxPanel Show one element inside a box panel
%
% obj = uiextras.BoxPanel() creates a box-styled panel object with
% automatic management of the contained widget or layout. The
% properties available are largely the same as the builtin UIPANEL
% object. Where more than one child is added, the currently visible
% child is determined using the SelectedChild property.
%
% obj = uiextras.BoxPanel(param,value,...) also sets one or more
% property values.
%
% See the <a href="matlab:doc uiextras.BoxPanel">documentation</a> for more detail and the list of properties.
%
% Examples:
% >> f = figure();
% >> p = uiextras.BoxPanel( 'Parent', f, 'Title', 'A BoxPanel', 'Padding', 5 );
% >> uicontrol( 'Style', 'frame', 'Parent', p, 'Background', 'r' )
%
% >> f = figure();
% >> p = uiextras.BoxPanel( 'Parent', f, 'Title', 'A BoxPanel', 'Padding', 5 );
% >> b = uiextras.HBox( 'Parent', p, 'Spacing', 5 );
% >> uicontrol( 'Style', 'listbox', 'Parent', b, 'String', {'Item 1','Item 2'} );
% >> uicontrol( 'Style', 'frame', 'Parent', b, 'Background', 'b' );
% >> set( b, 'Sizes', [100 -1] );
% >> p.FontSize = 12;
% >> p.FontWeight = 'bold';
% >> p.HelpFcn = @(x,y) disp('Help me!');
