Normally you should not be using setSize() but instead use pack() to all a frame to display at its preferred size.įor a more flexible layout that will calculate a proper preferred size of a panel check out the Wrap Layout. However the above solution will only work when components are added to the CENTER of the BorderLayout. Now the components will be able to wrap in the space available because by default the panel will be added to the BorderLayout.CENTER which takes up all the space available in the frame. de la biblioteca y no tiene que crear los componentes desde cero. You are overriding the default layout manager of the frame, so now the frame will respect the preferred size of the panel added to the frame, which means all the components will be displayed on a single line. Puede utilizar los componentes de la GUI de Java como el botón, el cuadro de texto, etc. setLayout(new FlowLayout(FlowLayout.LEFT)) The FlowLayout also respects the preferred size of components. You should note that the default layout manger for frames and applets is BorderLayout and the default for panels is FlowLayout. I have also tried to set width of the panel but it doesn't work!įlowLayout is designed to calculate its preferred size based on all components being displayed on a single line. SetLayout(new FlowLayout(FlowLayout.LEFT)) BorderLayout is the default layout manager for a frame one component per region FlowLayout A FlowLayout manager acts kind of like a word processor. SetDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) FlowLayout:, FlowLayout(FlowLayout.LEFT, 10, 20) //, 10, 20 - BorderLayout:, 5. TitledBorder titled = new TitledBorder("Name") The BorderLayout class defines five constants to identify each of the five areas. When you add a component to a container with a BorderLayout, you need to specify which of the five areas you want to add the component.
I am adding components in JPanel which is set as FlowLayout, they are not moving on next line even there is no space in left in that line. The BorderLayout divides a container’s space into five areas: north, south, east, west, and center.
