JFrame resizable height ONLY

Question

JFrame.setResizable(true) lets the user resize both the width and height of a window. Does a method exist which allows the user to ONLY resize the height?

Answer 1

I do not think there is a method expressly for that purpose. However, you could preset the JFrame's preferred, minimum, and maximum size such that the widths are all equal.

Dimension dimPreferred = frame.getPreferedSize();
Dimension dimMinimum = frame.getMinimumSize();
Dimension dimMaximum = frame.getMaximumSize();
dimPreferred.setWidth( FIXED_WIDTH );
dimMinimum.setWidth( FIXED_WIDTH );
dimMaximum.setWidth( FIXED_WIDTH );
frame.setPreferredSize( dimPreferred );
frame.setMinimumSize( dimMinimum );
frame.setMaximumSize( dimMaximum );

You will probably want to do this after frame.pack() and before frame.setVisible(true).
