[ControlP5] Basics - radioButton (it doesn't work nicely)

dogdogdog

hi,
somebody who know how to make each button from radio to the length from the text-label? (see line 10)

import controlP5.*;
ControlP5   cp5 = new ControlP5(this);

size(300, 200);

RadioButton r;
r = cp5.addRadioButton("radio")
.setNoneSelectedAllowed(false)
.setItemsPerRow(4)
//.setItemWidth(70)  //its to short  or to long
.addItem("sdfsdf ", 1)
.addItem("asdfasdf", 2)
.addItem("sdf", 3)
.addItem("dfsasdfasdf", 4)
;

for (Toggle t : r.getItems ()) {
  t.getCaptionLabel().align(CENTER, CENTER);
    t.getCaptionLabel().setControlFont(new ControlFont(createFont("Arial", 12)));
}

somebody an idea? ~:>

Changing the width of an individual item is easy but you can't set individual spacing!

int maxValue = 0;
  for (Toggle t : r.getItems ()) {
    t.getCaptionLabel().align(CENTER, CENTER);
    t.getCaptionLabel().setControlFont(new ControlFont(createFont("Arial", 12)));
    int w = (int) textWidth(t.getLabel());
    if (w > maxValue) maxValue = w;
    t.setSize((int) (w*1.33), 15);
  }
  r.setSpacingColumn(maxValue);

You will get better results if you don't create a new ControlFont for each Toggle.

thank you colouredmirrorball! :)
now it works.

..ok, but is there any other/better method to change my font from the radioButtons?

colouredmirrorball

ControlFont someFont = new ControlFont(createFont("Arial", 12));

(...)

t.getCaptionLabel().setControlFont(someFont);

In this simple example it would not matter much, but if you were doing this for a large list you'd end up with a large amount of controlFont objects which are all just the same, littering memory.

dogdogdog

alright ;)

but is there a difference between:
t.getCaptionLabel().setControlFont(new ControlFont(createFont("Arial", 12)));
and
t.captionLabel().setFont(createFont("Arial", 12));
?

colouredmirrorball

I don't think so. The Javadoc doesn't even mention the setControlFont() method.

dogdogdog

ok, but it's better to use the first or the second variety?

colouredmirrorball

I don't know for sure but it shouldn't matter much.
