The 1.java Abstract Window Toolkit (AWT) contains a number of classes to support GUI design2.AWT is provided by the Java java.awt package3. For GUI programming, understand: Container Class (Container), Component (component).The 4.button,scrollbar.canvas,list,checkbox,textfield,textarea,label class is a class in the java.awt package and is a subclass of the component (component) in the java.awt package.5.jav

Label:This article discusses if a cache table has the aging policy set, does the deletion of the data in the cached aging result in an impact to the Oracle database? If it is a read-only cache group, it will of course not affect Oracle. If it is an AWT cache group, the answer will not be affected, that is, the data deletion caused by aging is not propagated to Oracle, which is verified by experiment. Previous preparations to set up the cache group wer

Layout ManagerContainers can hold various components, and the location and size of the components are determined by the layout manager within the container. The following 5 layout managers are available for us in AWT:①flowlayout Streaming layout Manager②borderlayout Boundary layout Manager③gridlayout Grid Layout Manager④cradlayout Card Layout Manager⑤gridbaglayout Grid Package Layout ManagerThe layout of components in a container is usually controlled

This program calls the uimanager. getinstalledlookandfeels () method to obtain all the views installed on the local machine, and then creates a corresponding number of buttons to dynamically change the perception.

2. borderlayout Borderlayout is the default layout manager for Windows, frames, and dialog. The borderlayout layout manager divides containers into five areas: north, south, east, west, and center. Only one component can be placed in each area. Shows the location and size of each region: 　　　　 Example 5.5Import java. AWT .*;Public class buttondir {Public static void main (stri

program piece handle a static class (in place of the locally variable Main ()), and then:(2) Call Applet.stop () and Applet.destroy () in windowadapter.windowclosing () before we call System.exit ().Note the last line:Aframe.setvisible (TRUE);This is a change in the Java 1.1 AWT. The show () method is no longer supported, and setvisible (TRUE) replaces the show () method. When we learn Java beans later in this chapter, these seemingly easy to change
