Hello I have an odd question.

I want to know if and how to go about making universal settings for my Jlabels ,TextAreas and basically any text that can go on a panel. I have been writing the font sizes on every label to make it consistent. However the panels are growing and I don’t want to hard code the font size on every label.

Here are the sizes I am using and would like to use on all my labels, and textarea’s.

titlelb.getFont().deriveFont( Font.BOLD, (float) 20.); 
lb1.getFont().deriveFont( Font.PLAIN, (float) 11.);
lb2.getFont().deriveFont( Font.BOLD, (float) 11.);
textArea.setFont( Font.decode( "Arial-PLAIN-11"));

I am just wondering is there a way to set it universally where every Panel would inherit these specific sizes if that is at all possible, I don’t really know how to go about it for the sizes of the labels which is why I am here asking. Thank you in advance.

    You can change the font properties in the UIManager for every component you need by calling UIManager.put("nameOfFontProperty", new Font(Font.DIALOG, FONT.PLAIN, sizeInPixel));. You can find a list with the default properties here.

    One example to make the font of all labels a size of 20px do:

    UIManager.put("Label.font", UIManager.getFont("Label.font").deriveFont(20.0));
SwingUtilities.updateComponentTreeUI(yourJFrame);
