Alrighty, so I made a nice Custom NSWindow in Coca-Java that I could drag around and resize. There's only one catch: after dragging it a around enough, I will eventually get it to crash. Here's my stacktrace in Project Builder's debugger:


So, does anyone see what's going on? Here's my drag code for reference:

<BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>
public void mouseDragged(NSEvent theEvent)
{
NSPoint currentLocation;
NSPoint newOrigin;
NSRect screenFrame = NSScreen.mainScreen().frame();
windowFrame = this.frame();


if(!lowerRightCorner) <font color = brown>//just dragging</font>
{
<font color = brown>//grab the current global mouse location; we could just as easily get the mouse location </font>
<font color = brown>//in the same way as we do in -mouseDown:</font>
currentLocation = this.convertBaseToScreen(this.mouseLocationOutside OfEventStream());
newOrigin = new NSPoint(currentLocation.x() - initialLocation.x(), currentLocation.y() - initialLocation.y());

<font color = brown>// Don't let window get dragged up under the menu bar</font>
if( (newOrigin.y()+windowFrame.size().height()<font color = blue>+22</font>) &gt; (screenFrame.origin().y()+screenFrame.size().heigh t()) )
{
newOrigin = new NSPoint(newOrigin.x(), screenFrame.origin().y() + (screenFrame.size().height()-windowFrame.size().height()<font color = blue>-22</font>));
}

<font color = brown>//go ahead and move the window to the new location</font>
this.setFrameOrigin(newOrigin);
}
}
</font>[/code]

Thanks in advance,
F-bacher

Hmm... that looks like a stack trace of native code, and you probably want a Java stack trace. Have you set your executable target in Project Builder to use the Jav debugger instead of gdb?

Ahhh... no I did not. That could be useful. I'll try that when I get home... in 5 hours.

Thanks,

This must be a very serious problem, cause it even crashes the java debugger! And I just found out that using the QT API's likes to make my interface totally unresponsive. How can two seemingly easy issues (seeing if my NSMovie is done playing, dragging an NSWindow) be holding me up so long.

Grrr...
