[GUI programming] - setFont() in JFrame

[loris]

Good day,

I'm pretty new in the endless programming world of Java and my question might sound stupid but as I haven't found any answer by myself...

So, I've created a JFrame composed of several JPanel objects. Each of these latter JPanel contains one or several elements such as buttons or labels. I'd like to use a font (e.g. plain Tahoma 11) being different from the defaulted one for every text being displayed in my JFrame WITHOUT having to apply such a definiton to every element contained in there. In other words, I'd like to get rid of the following code (i.e. loads of redundancy) by replacing it by only 1 line of code that would apply to all components:

btnOpen.setFont(new Font("Tahoma", 0, 11)); 
btnForward.setFont(new Font("Tahoma", 0, 11)); 
btnClose.setFont(new Font("Tahoma", 0, 11)); 
lblName.setFont(new Font("Tahoma", 0, 11)); 
lblSurame.setFont(new Font("Tahoma", 0, 11));

Is it possible and, if yes, how could I proceed? Thanks very much in advance for a potential answer!

hi everyone,


try this,

Font f = new Font("Tahoma", 0, 11)

btnOpen.setFont(f);
btnForward.setFont(f);
btnClose.setFont(f);
lblName.setFont(f);
lblSurame.setFont(f);

ps: There is no such thing as a stupid question

Hi,

Cheers for the reply. Unfortunately, the proposed code doesn't really achieve what I want to do. I might have explained my problem quite badly and I'll try to improve that hereafter: I'd like to avoid having to define the font for every component and replace the 5 (or more) following lines of code by only one line that would define the font for every component displaying text in the JFrame.

btnOpen.setFont(new Font("Tahoma", 0, 11)); 
btnForward.setFont(new Font("Tahoma", 0, 11)); 
btnClose.setFont(new Font("Tahoma", 0, 11)); 
lblName.setFont(new Font("Tahoma", 0, 11)); 
lblSurame.setFont(new Font("Tahoma", 0, 11)); 
// ... (the list continues and can be quite long)

While writing this, I've got an idea I'll try out asap: identify all the components and, where appropriate, set the font by applying a loop at the end of the class defining the JFrame.

More on this later...!

Hi everyone,

You can write a function which has the font instance as an argumen and you can add the components as you usually do to the frame and then call the function at the end. I am assuming that you want the same font for all the jcomponents

example

void init (Font f)
{

JComponent [ ] comp = Frame.getComponents();

for(i=0;i<comp.length;i++)
{
comp[i].setFont(f);
}

}

I hope this helps you

Yours Sincerely

JFrame has only a JContentPane as a component,

so, it must be

JComponent [ ] comps = frame.getContentPane().getComponents();

hi everyone,

Yes, floaty is right about the getContentPane() method. I missed that out because i sometimes use awt and got very used it. I apologize.

The rest of the method remains the same.
