From: wma on 8 Feb 2010 05:30 Hello, is there a possibility to hide (disable) a jlabel which is created like this: global output global jLabel global hcomponent global hcontainer output = '<html><p>test</p></html>'; jLabel = javaObjectEDT('javax.swing.JLabel',output); [hcomponent,hcontainer] = javacomponent(jLabel,[10,10,610,420],gcf); i already tried jLabel.list but i cannot find anything. I have several menuitems where i have to switch the text inside the label. I need rich-text functions so i have to use something like jlabel right? Does anyone can paste code for jtextea ?

Use the UIInspect utility to understand which methods and properties are available on your object: http://www.mathworks.com/matlabcentral/fileexchange/17935-uiinspect-display-methodspropertiescallbacks-of-an-object . In your specific case, there are separate properties (and accessor methods) for hiding/showing and for enabling/disabling. 2.

In your case, handles.introtext may be an empty or invalid handle - set a breakpoint and check. To completely delete the label, simply do delete(introtext), just like for any other Matlab control. As before, you need a valid handle or else it will not work. Yair Altman http://UndocumentedMatlab.com |
