#New flowlayout null pointer exception update
NET Installation and Configuration Issues Null pointer exception on bulk update but working when I update manually via UI. The exception occurs when I enable newGameButton in the nested class "CardPanel". The JButton "newGameButton" is declared in the class TriPeaksPanel. This returns a null pointer exception - so my question is: how do I create a. Uses a panel with a right-aligned FlowLayout presenting two buttons.Public class TriPeaksPanel extends JPanel Note that I use a nested class. setLayout(new BorderLayout()) JTable table new JTable() JScrollPane. When the FlowLayout object controls a container with a left-to right component orientation (the default), the LEADING value specifies the components to be left-aligned and the TRAILING value specifies the components to be right-aligned.

How to Use Buttons, Check Boxes, and Radio Buttons The alignment argument can be FlowLayout.LEADING, FlowLayout.CENTER, or FlowLayout.TRAILING. If you set the RIGHT_TO_LEFT constant to true and recompile, you can see how FlowLayout handles a container that has a right-to-left component orientation.Ĭenters a component nicely in the top part of a BorderLayout, and puts the component in a JPanel that uses a FlowLayout. Sets up a content pane to use FlowLayout.

The following table lists code examples that use the FlowLayout class and provides links to related sections. The hgap and vgap arguments specify the number of pixels to put between components. When the FlowLayout object controls a container with a left-to right component orientation (the default), the LEADING value specifies the components to be left-aligned and the TRAILING value specifies the components to be right-aligned.įlowLayout (int align, int hgap, int vgap)Ĭreates a new flow layout manager with the indicated alignment and the indicated horizontal and vertical gaps.

Another constructor of the FlowLayout class specifies how much vertical or horizontal padding is put around the components. To specify that the row is to aligned either to the left or right, use a FlowLayout constructor that takes an alignment argument. If the container is wider than necessary for a row of components, the row is, by default, centered horizontally within the container.
If the horizontal space in the container is too small to put all the components in one row, the FlowLayout class uses multiple rows. The FlowLayout class puts components in a row, sized at their preferred size. Alternatively, to compile and run the example yourself, consult the example index.

Java™ Web Start ( download JDK 7 or later). The following figure represents a snapshot of an application that uses the flow layout:Ĭlick the Launch button to run FlowLayoutDemo using If you are interested in using JavaFX to create your GUI, seeįlowLayout class provides a very simple layout manager that is used, by default, by the JPanel objects. final NullPointerException result new NullPointerException(String.format(getLoggingLocale(), nullParamNPEstr(), name)) final StackTraceElement st. Otherwise, if you want to code by hand and do not want to use GroupLayout, then GridBagLayout is recommended as the next most flexible and powerful layout manager. If you are not interested in learning all the details of layout management, you might prefer to use the GroupLayout layout manager combined with a builder tool to lay out your GUI.
It then confirms whether or not the date is legitimate or not. Note: This lesson covers writing layout code by hand, which can be challenging. Homework Statement I am making a very, very simple program that takes in the date (of type string) from the user in the form DD/MM/YYYY.
