ListComboBox: change the fontsize of the listitems

Postby td84 » Wed Dec 06, 2017 6:36 am

Hello,

i would like to change the fontsize of the items in a com.jidesoft.combobox.ListComboBox.
My try was to get the renderer and set the font of the Component returned by the renderer, but i get a nullpointerexception:
Can You help me?

Code: Select all
public class MyListComboBox extends ListComboBox {
   private ListCellRenderer superRenderer;
   private ListCellRenderer myRenderer;
   

   public MyListComboBox(Object[] objects, Class<?> clazz) {
      super(objects, clazz);
      initMyRenderer();
   }
   
   
   public MyListComboBox(ComboBoxModel model) {
      super(model);
      initMyRenderer();
   }
   
   
   public void initMyRenderer() {
      myRenderer = new ListCellRenderer() {
         @Override public Component getListCellRendererComponent(JList list, Object value, int index,
                      boolean isSelected, boolean cellHasFocus) {
            System.out.format("\nmyRenderer() - super: [%s]\n", superRenderer);
            Component comp = superRenderer.getListCellRendererComponent(list, value, index, isSelected, cellHasFocus);
            comp.setFont( new Font("Segoe UI", Font.PLAIN, 14) );
            return comp;
         }
      };
   }
   
   
   @Override public ListCellRenderer getRenderer() {
      superRenderer = super.getRenderer();
      System.out.format("\ngetRenderer() - super: [%s]\n", superRenderer);
      return myRenderer;
   }
}


Thanx in advance,
Daniel

Try ListExComboBox because that's one we will maintain moving forward.

Ok, thanx. Do you mean instead extends ListComboBox i should write extends ListExComboBox and it will work?
Could you please post a small example?

Thank you,
Daniel

You had the code. Just replace ListComboBox with ListExComboBox.

Thanx it worked, but now i have 2 other issues:
1) the Look&Feel of the dropdown changed from the "white box" to the "grey box" (see attachments). I would like to have the "white box" (while using ListExComboBox).
2) if i select something in the dropdown, the text that is sowing in the "gery box" has still the old font shape. (but the text in the dropdown-list has the new font shape)

Can you help me with these?

Thanx again,
Daniel

Thanx, but i set it deliberately noneditable. In the old Version (with ListComboBox) i got the right UI even if i set it to noneditable.
Is it no way to keep it noneditable and have the old L&F?

There is no way to do that. That's how JComboBox looks as well.

Ok, i understand. Do you allow me a last question ?
How can i change the fontsize of the selected text, that is showing in the Textfield not in the Dropdown-list?
I mean: i would like to set the size of "Yes" to 14. Actually it's 12 as you can see on the picture.

Thank you again,
Daniel

That's the renderer. Non-editable combobox doesn't have a text field. It used the same list renderer to render the text on the combobox.

Ok, than maybe i make something wrong, because the "Yes" in the combobox is still is smaller, then in the dropdown-list.
I also set a bold fontface for dropdown-list, but the text in the combobox doesn't appear in bold.
Could you help to fix it?

Thanx,
Daniel

I fixed it. Simpli calling setFont() on a ExComboBox instance did it. The renderer has affect on the items in the Dropdown-list but not on the text in the Combobox.
