JDK-4038721 - Win32:MouseDrag issues an event incorrectl
Description
On WinNT, if I button-down on one of the navigation buttons, but then decide that I don't want to do that action, even if I move off of the button before letting the button up, the action still happens.  That's not what happens on Solaris.  (I haven't tried Win95.)

------------
Made changes to awt_Component.cpp and awt_Toolkit.cpp. Reviewed by Robert Bruce. Also see BugId 4038721, where the changes fixed that bug as well.

In awt_Component.cpp, removed WM_MOUSEMOVE simulation in SetCursor, and changed MouseMove function to set m_dragged flag and not eat mouse messages.

EVALUATION mike.somlo@eng 1997-10-09 The button does get an extra MOUSE_PRESSED event when the mouse is no longer over the button. Here is code to test this: import java.awt.*; import java.awt.event.*; class Test extends Frame implements MouseListener, WindowListener { Button btn = new Button("Click Me!"); public void windowOpened( WindowEvent e) {} public void windowClosing( WindowEvent e) { System.exit(0); } public void windowClosed( WindowEvent e) {} public void windowIconified( WindowEvent e) {} public void windowDeiconified( WindowEvent e) {} public void windowActivated( WindowEvent e) {} public void windowDeactivated( WindowEvent e) {} public void mousePressed( MouseEvent evt ) { System.out.println("mousePressed"); } public void mouseEntered(MouseEvent e) {} public void mouseExited(MouseEvent e) { System.out.println("mouseExited"); } public void mouseReleased(MouseEvent e) {} public void mouseClicked( MouseEvent e ) { System.out.println("mouseClicked"); } public Test() { addWindowListener(this); setLayout(null); setSize(200,150); addNotify(); btn.setBounds(30, 70, 120, 40); add(btn); btn.addMouseListener(this); show(); } public static void main(String argv[]) { Test t = new Test(); } }
