About Modal Forms Only JDialog in Swing can be set to a Modal form, whose methods can be passed in a constructor (such as "JDialog (Frame owner, Boolean Modal)"), or by using the Setmodal (Boolean) method, which A method is inherited from the Dialog class. In the JFrame class, the Modal form cannot be set through a method such as JDialog, where a friend tries to simulate a windowdeiconified form by Requestfocus () at Modal (), as follows: public

use internal classes to solve this problem. The form of the inner class is as follows: Class Outer { int outer_int; Class Inner { int inner_int; } One advantage of using an inner class is that in an inner class, you can directly use the properties and methods in the external class. We use the following code to try to implement this design task. 3. Code Version1 Import javax.swing.*; Import java.awt.*; Import java.awt.event.*; public class Newtwobuttons {

drawn by drawing in its container window through Java drawing techniques because it is painted. Therefore, it can realize the "transparent" effect of the component, and it can achieve the performance on different platforms, and the cost of component drawing and event processing is much smaller, which improves the efficiency of program running. 4. Because lightweight components must be drawn in their own windows and eventually included in a weight container, several top-level containers in swin

the interface, declare the control, and then start editing the interface. For the interface, the first is a frame frame, for frame, you can set its title settitle (); (the title can also be created when the caption is determined in the constructor.) ), and then the window size, which may be a headache for beginners, in the end to set how much? In fact, it is very simple, in the Java core volume a function, you can get the actual size of the PC window, according to this value to adjust the line.

1. Structural Partitioning There are two types of Swing components, one is the JComponent class and one is the Windows class. Where the Windows class contains components that can be displayed independently, and the JComponent class contains components that cannot be displayed independently . What are components that can be displayed independently, and components that cannot be displayed independently? components that can be displayed independently : When you run a program, components that can b
