I have a few JSpinner(s) and I'm trying to change the button sizes.
I know how to change the font of the SpinnerModel(s),
but not the button sizes.
Can someone please point me in the right direction?
TIA!

@hfx642 good question +1

but SpinnerModel has nothing to do with JSpinner' View, there you have to change Font, its size ...

to the JButton size(s) that's depend of JSpinner size, or are you meaning triagle JButtons Icon ???

anyway there are two way

1/ extract all JComponents from JSpinner (JFormattedTextField + two JButtons)

a/ by DefaultSpinnerUI but overide that for all Native OS
b/ MetalSpinnerUI for reduced usage of ..

2/ create own/custom JComponents

Edited 5 Years Ago by mKorbel: n/a

I understand that the SpinnerModel has nothing to do with sizing.
I was just trying to say that I can change the font of the JTextField contained within the JSpinner.
I realize that I would have to isolate the two JButtons,
(as I have already isolated the JTextField to change the font),
but how do I change the size of the JButtons?
TIA!

Font in JTextField ???

o.k. please edit my code with your question, beacuse/maybe there is/are small mistake(s), just with intention to avoid that :-)

1/ how you are extract JTextField, because there is JFormattedTextField

2/ and override preffered size for Two JButtons (hint change Icon)

EDIT: why reinvent the wheel, because there are lots of Custom Java Look & Feel, with non-bugged setting for majorities of JComponents and with correct output to the GUI

Altering the code presented, as follows...

JSpinner s3 = new JSpinner();

// This will alter the Size of the entire JSpinner... but so does a font change
s3.setPreferredSize(new Dimension(100, 100));

// As long as the dimensions fit within the JSpinner size,
// this will enlarge the X Size of the button (but not the Y Size),
s3.getComponent (0).setPreferredSize (new Dimension (75, 75));
// which IS what I was looking for.

...does the trick.
Thank-You!!!

HI,

I too have the same problem. I have followed the example.I am using windows 7 if I look and feel as "com.sun.java.swing.plaf.windows.WindowsLookAndFeel" it works fine if not it does not works. Any idea to solve this isssue?

Regards,
Selva.

Even though I was able to make the example work,
I still haven't been able to make MY application work.
(I'll get back to it some time next month. I have other stuff to do for now.)
