[Jython-users] Again Look and Feel related

[Patrick B. <bi...@st...>]

Hi Guys,
 
This is how it is in java...
 
public void setSystemLookAndFeel() { 
    try { 
        UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());

    } 
    catch (ClassNotFoundException ex) { 
        ex.printStackTrace(); 
    } 
    catch (InstantiationException ex) { 
        ex.printStackTrace(); 
    } 
    catch (IllegalAccessException ex) { 
        ex.printStackTrace(); 
    } 
    catch (UnsupportedLookAndFeelException ex) { 
        ex.printStackTrace(); 
    } 
} 

And this is how it is in my jython-module...

try:
 
swing.UIManager.setLookAndFeel(swing.UIManager.getSystemLookAndFeelClassName
())
except:
    print "set look and feel failed"

But how can you trap the various kinds of errors ???
For example, when it is a ClassNotFoundException, how
do i trap this in the except to print various output
to the console when various errors occour ?

so it it okay to use...

except ClassNotFoundException:
    print "Class not Found"
except InstantiationException:
    print "InstantiationException"
except IllegalAccessException:
    print "Illegal Access to Class"
except UnsupportedLookAndFeelException:
    print "Provided look and feel is not supported"

or is there a better solution ?
    
Strange that this code works anyway in jython, cause java
normally requires you to add all the exceptions in the code.
If avoiding to add one of them results in a compile error
on javac, telling that you need to obtain all the exceptions.
