[Java swing tycoon] is implemented under swing using the JPanel simulation button.

button click Need to let JPanel implement mouse click event. Follow the effect of the switch, you can achieve the effect of the button.

As an example:

There is a "buy" button, images as follows

Normal

MouseOver:

Disabled

Pressed

The code is as follows:

 Public classShopbuttonextendsJPanelImplementsMouseListener {PrivateShop Shopui; Privateimage[] img; PrivateImage Normalimage; PrivateImage Rolloverimage; PrivateImage Pressedimage; PrivateImage Disabledimage; PrivateImage Currentimage; Private BooleanEnabled =true; PrivateString name =NULL; Privatecontrol control;  PublicShopbutton (Shop shopui,string name,intXintY,control Control) {         This. Shopui =Shopui;  This. name = name;//Set name         This. Control =control;  This. IMG = This. shopui.createcardimg (name);//This is the use of the Factory mode to get IMG Resources         This. Normalimage = This. img[0];  This. Rolloverimage = This. img[1];  This. Pressedimage = This. img[2];  This. Disabledimage = This. img[3];  This. Currentimage =Normalimage;  This. setbounds (x, Y, This. Img[0].getwidth (NULL), This. Img[0].getheight (NULL));  This. Addmouselistener ( This); }         Public Booleanisenabled () {returnenabled; }     Public voidSetEnabled (Booleanenabled) {         This. Enabled =enabled; }     Public voidPaint (Graphics g) { This. Setopaque (false);//Transparent Background        if(enabled) {G.drawimage (Currentimage, This. GetX (), This. GetY (), This. GetWidth (), This. GetHeight (), This); } Else if(! (Name.equals ("buy") | | name.equals ("Cancel")) {g.drawimage (disabledimage, This. GetX (), This. GetY (), This. GetWidth (), This. GetHeight (), This); }} @Override Public voidmouseclicked (MouseEvent e) {} @Override Public voidmousepressed (MouseEvent e) {currentimage=Pressedimage; if(enabled) {if( This. Name.equals ("close")) {//exit the store                     This. Shopui.movetoback ();  This. Control.exitshop (); } Else if( This. Name.equals ("Cancel")) {//Cancel Current selection                     This. Shopui.setchoosecard (NULL); } Else if( This. Name.equals ("buy")) {//Buy Current selection                     This. Control.buycard ( This. Shopui.getshop ()); } Else {                     This. Shopui.setchoosecard ( This); } }} @Override Public voidmousereleased (MouseEvent e) {currentimage=Rolloverimage; } @Override Public voidmouseentered (MouseEvent e) {currentimage=Rolloverimage; } @Override Public voidmouseexited (MouseEvent e) {currentimage=Normalimage; }}

An appropriate extension can be made into a generic class that simulates a variety of button classes.

The following is the store interface within the mini monopoly: the red box is the extension implementation
