HGTable Example
Uses the "hgtable" functions to display a multi-column list
Contents
Create figure and list box
f = figure('Name','HGTable Example','NumberTitle','off','Visible','off'); b = uicontrol('parent',f,'style','listbox',... 'Units','Normalized','Position',[0.1 0.1 0.8 0.8]); % Create local anonymous functions for callbacks from the list. opencb = @(src,evt) fprintf(1,'Item %d opened\n',evt); selectioncb = @(src,evt) fprintf(1,'Item %d selected\n',evt); % Set the properties of the list box, including font, selection behaviour, % and callbacks. tablesetup(b,selectioncb,opencb);
Create sample data from properties of list box
Each column needs to be a cell array of strings. We'll have columns for: property name, property data type, the size of the value for that property, and lastly the value itself (if it is a string).
p = get(b); propnames = fieldnames(p); datatype = cell(size(propnames)); datasize = cell(size(propnames)); stringdata = cell(size(propnames)); for i=1:numel(propnames) v = get(b,propnames{i}); datatype{i} = class(v); s = size(v); datasize{i} = sprintf('%d*%d',s(1),s(2)); if ischar(v) stringdata{i} = v; else stringdata{i} = '<not a string>'; end end
Display data in list box
The function "formattable" does everything for us. We could, if necessary, format columns individually using "tablecolumn", join them together using "tablestrings", and set that as the string for the list box.
formattable(b,{'Property Name','Data Type','Data Size','Data'},...
propnames,datatype,datasize,stringdata);
set(f,'Visible','on');
