Some parts of JFrame off screen

**cwbr** · 01-26-2012, 04:36 PM

I have a JFrame with an Image drawn onto it. The JFrame is 400x300, as is the Image. Unfortunately, some of the Image is not being drawn to the screen. I'm pretty sure it's in the right place as far as the JFrame is concerned, but the window border, and the title bar are hiding some of the Image. How do I get the contents of the window to be 400x300, rather than the window itself?
Is it just trial and error, or is there a better way?
Thanks

Can't you just set the size of the component drawing the image?

Or just use a JLabel with an ImageIcon added to the CENTER of the JFrame's default BorderLayout, and call pack()

The component drawing the image? I don't understand. I have JFrame.setSize(400, 300), and then I use Graphics2D.drawImage to draw an image to it, but the border of the window that comes up hides some of the image.

I'm sure there must be a better way of doing it than having to put in a JLabel, but if it comes to that I'll try it.

Here's how it comes out if I make the JFrame 400x300:

The first thing you're doing wrong is performing custom painting in a top level window.

If for whatever crazy reason you're not comfortable with a JLabel/ImageIcon, then learn how to do custom painting correctly:

The JFrame is 400x300, as is the Image.

Well, you can't make the frame the same size as the image because the frame also has a titlebar and borders to worry about.

I'm sure there must be a better way of doing it than having to put in a JLabel,

That IS the better way.

There is no need to reinvent the wheel by doing the custom painting yourself.

I've solved this now...but I'm not sure if you can delete threads once they're done.

Why would you want to delete it? Part of the purpose behind these forums is so that other people with similar problems in the future can learn from the answers you received. With that in mind, you might consider posting what you did to solve your problem.

I'm not sure it's that easy to find a solution by looking through old threads, but in case someone does the solution provided by DarrylBurke (i.e. custom painting) worked nicely.

It is if the original posters provide meaningful titles and detailed questions. Who knows, coming across this thread might make somebody's day a year from now (hi, people of the future!).
