JSwing components don't appear until frame is

• Java Layout not showing components (sometimes) 1 answer

bit of an issue. I'm trying to make a JSwing frame with a label, textfield, and two buttons. When the routine first runs, the buttons and the textframe are invisible. When I resize the frame, the buttons and textframe appear, and remain there when I return the frame to its original size. Any ideas why this is happening?

回答1:

You should call setVisible(true) on your frame after you added the components to get them rendered in your frame. See this answer for more information.

After adding the elements, you may want to call revalidate(). Post your code for more help.
