Java Forum / GUI / October 2005Why is show() prevailing?
This is largely off-topic but might be educational on some aspect. A major percentage of beginners' Swing code use show() method for JFrame visibility. Of course it gets compiler warning. Why on earth youngest generation keep using an old deprecated API in such a prevailing way? >From some point of time, Swing designers have surrendered to the JavaBeans convention of class structure and member naming. We have torrent of get/is/set methods today. Why so many of beginners could be immune to the trend? > This is largely off-topic but might be educational on some aspect. > [quoted text clipped - 8 lines] > torrent of get/is/set methods today. Why so many of beginners could > be immune to the trend? show() conveys the intent much more readily than setVisible(true)? Honestly, bean conventions be damned, show() is much more sensible. I use setVisible(true), but only because I don't want to see the warnings.

You are not just setting a visibility property. You are causing work to be done to actually show the component.

Does that work get done on second and subsequent calls to setVisible(true)? If not 'constructAndShow()' would be more accurate for the first invocation, while 'setVisible(true)' better represents the subsequent calls. Of course, it is better to use one or the other consistently. I prefer setVisible(true) simply for the consistency with set/get. On the matter of why there is still so much of it.. - I agree with Monique 'show() conveys the intent much more readily than setVisible(true)' - show() was only deprecated in 1.5. >Why on earth youngest generation keep using an old deprecated API >in such a prevailing way?

The vast majority of Sun example codes, as one (significant) example.. Oh all the good people on the bench try to show() something. Well i think all of you are right. The major reason behind using show() method is read from some older books just as i do before coming on this forum but it runs fine under jdk1.4.1. I read from dietel and dietel 3rd edition. I only know it from Andrew that it can be replaced with setVisible(). I only need to know is it alright to use setSize(x,y) before setVisible(). Or any other api will do this. >I only need to know is it alright to use setSize(x,y) before >setVisible(). see http://mindprod.com/jgloss/layout.html Most of the time you let the layout manager do the setSize for you. For JFrames you do the setSize, then validate() then setVisible(true).
