Swing製作類似QQ的自動隱藏界面

這個程序實現了類似QQ的自動隱藏界面和網上其它的實現方式不同這種實現方式是以事件驅動的，不會佔用過多的系統資源.實現了界面四個方向上的靠邊隱藏。關鍵代碼如下：

private class DockRunnable implements ActionListener { public void actionPerformed(ActionEvent e) { if(status == PENDING) { Point loc = frame.getLocationOnScreen(); if(frame.getBounds().contains(loc)) (new Timer(1000, this)).start(); else dockShell(frame, dockSide); } } } private void dockShell(JFrame shell, int side) { Rectangle shellBound = shell.getBounds(); Rectangle displayBound = translucencyCapableGC.getBounds(); if(shellBound.x != 0 && shellBound.y != 0 && shellBound.x + shellBound.width != displayBound.width && shellBound.y + shellBound.height != displayBound.height) return; status = DOCKING; dockSide = side; switch(side) { case RIGHT: shellBound.x = displayBound.width - 2; shellBound.y = 0; shellBound.height = lastBound.height; shell.setBounds(shellBound); break; case LEFT: shellBound.x = 2 - shellBound.width; shellBound.y = 0; shellBound.height = lastBound.height; shell.setBounds(shellBound); break; case TOP: shellBound.y = 2 - shellBound.height; shell.setBounds(shellBound); break; case BOTTOM: shellBound.y = displayBound.height - 1; shell.setBounds(shellBound); break; } } /** * 暫時取消dock，如果鼠標移出主窗口則回覆dock */ public void pend() { Rectangle shellBound = frame.getBounds(); Rectangle displayBound = translucencyCapableGC.getBounds(); status = PRE_PENDING; switch(dockSide) { case RIGHT: frame.setLocation(displayBound.width - shellBound.width, 0); break; case LEFT: frame.setLocation(0, 0); break; case TOP: frame.setLocation(shellBound.x, 0); break; case BOTTOM: frame.setLocation(shellBound.x, displayBound.height - shellBound.height); break; } status = PENDING; (new Timer(1000, new DockRunnable())).start(); } private void dockShell(JFrame shell) { Rectangle shellBound = frame.getBounds(); Rectangle displayBound = translucencyCapableGC.getBounds(); if(status == DOCKING) { switch(dockSide) { case RIGHT: frame.setLocation(displayBound.width - 2, 0); break; case LEFT: frame.setLocation(2 - shellBound.width, 0); break; case TOP: frame.setLocation(shellBound.x, 2 - shellBound.height); break; case BOTTOM: frame.setLocation(shellBound.x, displayBound.height - 1); break; } } else if(status == PENDING) { //恢復大小 if(dockSide == RIGHT || dockSide == LEFT) frame.setSize(shellBound.width, lastBound.height); status = OFF; } else if(shellBound.x + shellBound.width > displayBound.width) { // 右邊 shellBound.x = displayBound.width - 2; shellBound.y = 0; shellBound.height = lastBound.height; frame.setBounds(shellBound); status = DOCKING; dockSide = RIGHT; } else if(shellBound.x < 0) { // 左邊 shellBound.x = 2 - shellBound.width; shellBound.y = 0; shellBound.height = lastBound.height; frame.setBounds(shellBound); status = DOCKING; dockSide = LEFT; } else if(shellBound.y < 0) { // 上邊 shellBound.y = 2 - shellBound.height; System.out.println("TOP"+shellBound.height); frame.setBounds(shellBound); status = DOCKING; dockSide = TOP; } else if(shellBound.y + shellBound.height > displayBound.height) { // 下邊 shellBound.y = displayBound.height - 1; frame.setBounds(shellBound); status = DOCKING; dockSide = BOTTOM; } } public void mouseClicked(MouseEvent e) { } public void mouseEntered(MouseEvent e) { if(status == DOCKING) pend(); } public void mouseExited(MouseEvent e) { dockShell(frame,dockSide); } public void mousePressed(MouseEvent e) { isDraging = true; xx = e.getX(); yy = e.getY(); } public void mouseReleased(MouseEvent e) { isDraging = false; dockShell(frame); } public void mouseDragged(MouseEvent e) { if (isDraging) { int left = frame.getLocation().x; int top = frame.getLocation().y; frame.setLocation(left + e.getX() - xx, top + e.getY() - yy); frame.repaint(); lastBound = frame.getBounds(); } } public void mouseMoved(MouseEvent e) { if(status == PENDING) dockShell(frame); }
