Hi All,
I have a modal progress dialog that I present while waiting for a library to
finish a long running operation. The library periodically calls an idle
proc. In my idle proc, I use NSApp runModalSession: to run the progress
dialog.
The problem is that if I move the dialog window by dragging the window title
bar, controls within the progress dialog no longer respond to mouse clicks.
Specifically, I can no longer click in a Cancel button. Interestingly, the
button continues to respond to keyboard events (Command-.).
The dialog window is an NSPanel loaded from a nib file. This happens on
both Panther and Tiger systems. Does anyone have any ideas what I might be
doing wrong?
Here's the code that displays and runs the progress dialog:
- (void) showProgress
{
if (!mVisible)
{
mInterrupted = N;
if (!mStartDate)
mStartDate = [[NSDate alloc] init];
else if (mStartDate && [[NSDate date]
] >= kShowInterval)
{
[mStartDate release];
mStartDate = nil;
[mInterrupt setEnabled:YES];
[mProgress startAnimation:self];
mModalSession = [NSApp ];
[mWindow makeKeyAFront:self];
mVisible = YES;
}
}
}
- (void) runProgress
{
if (mVisible)
{
if (!mLastRun || [mLastRun timeIntervalSinceNow] < -kRunInterval)
{
int r = [NSApp runModalSession:mModalSession];
if (r != NSRunContinuesResponse)
{
#ifdef DEBUG
NSLog(@"progress: %d", r);
#endif
}
[mLastRun release];
mLastRun = [[NSDate date] retain];
}
}
}
- (void) hideProgress
{
if (mVisible)
{
[mProgress stopAnimation:self];
[NSApp endModalSession:mModalSession];
[mWindow :self];
mVisible = N;
}
[mLastRun release];
mLastRun = nil;
[mStartDate release];
mStartDate = nil;
}
Cheers
