Maximizing Jinternal frame

[fatcodeguy]

hi... I'm trying to maximize a JInternalFrame using

try{setMaximum(true);}
catch(java.beans.PropertyVetoException ee){}

but I get a null pointer exception error at (unknownsources)
javax.swing.DefaultDesktopManager.maximizeFrame
javax.swing.plaf.basic.BasicInternalFrameUI.maximizeFrame
javax.swing.plaf.basic.BasicInternalFrameUI$InternalFramePropertyChangeListener.propertyChange(Unknown Source)

Any ideas?, thanks

are you trying to maximise within the JInternal frame iteself?

in which case you may need to do the following:

try{this.setMaximum(true);}
catch(java.beans.PropertyVetoException ee){}

otherwise, just reference the frame object by its name

try{yourFrame.setMaximum(true);}
catch(java.beans.PropertyVetoException ee){}
