Bug in NSTextView delegate

Hi,

I thing that NSTextView sends 'NSTextDidChangeNotification' also in
cases, when the text are not changed (for example, when I change color
of text or font of text).
This notification are posted in 'didChangeText'. This notification
should be posted only when I change text (by typeing from keyboard, or
from clipboard).

thank you.

The documentation I have says that this is correct, at least it is
what happens on recent Apple systems ...

Do you have any evidence that it is not correct ?

RE: Bug in NSTextView delegate

Hi, on Openstep for Mach 4.2 this notification is send only when text is
changed.

For example: when user type wrong text (character) I want to change color of
text. When I change color in notification method, this method is invoked
ones more (becouse it is selector of observer of
NSTextDidChangeNotification) and after several calls application crashed.

I thing that changeing of color of NSText is not change of characters in
NSText, so that why the NSTextDidChangeNotification should not be sended.

Problem with NSColor/NSString initialisation

While searching for another problem in NSComboBoxCell I ran into an
initialization problem that I don't quite understand. Perhaps someone on
this list can explain it and even fix it?

When running this small test program, I get a lot of error messages from
NSColor.

#include <Foundation/NSAutoreleasePool.h>
#include <Foundation/NSString.h>
#include <AppKit/NSComboBox.h>
#include <AppKit/NSComboBoxCell.h>

int main (int argc, const char *argv[])
{
  CREATE_AUTORELEASE_POOL(pool);
  NSComboBox *cb;
  int n = 0;
/*
  NSString *str =  <at> "0.000000 0.000000 0.000000";
  const char	*ptr = [str cString];
  float		r, g, b;

  //NSLog( <at> "Found string %s", ptr);
  n = sscanf(ptr, "%f %f %f", &r, &g, &b);
  if (n == 3)
  {
      NSLog( <at> "Resulted in Color %f, %f, %f", r, g, b);
  }
  else
      NSLog( <at> "Only found %d", n);

Fix: NSView, setBoundsOrigin:

Hi,

here is a patch for NSView to renew the gstate after setting a new origin.
I hope it is useful ...

ANNOUNCE: GNUstep LaunchPad Version 1.0.0 Released

ANNOUNCE: GNUstep LaunchPad Version 1.0.0 Released

GNUstep Developers are happy to announce the first user release of
GNUstep LaunchPad. GNUstep LaunchPad is a collection of libraries for
creating non-graphical tools and applications using an API based on
OpenStep and the MacOS X API.  As with its godfather, the OpenStep
system developed by NeXT, developers have noted that GNUstep allows
faster development time and more flexibility than with other common
application development libraries.

GNUstep Launchpad consists of the following packages:

GNUstep Make - A collection of make scripts that make configuration,
building and packaging of projects almost trivial.

GNUstep Base - A collection of Objective-C classes that provide all
the fundamental objects required in most applications, such as
dictionaries, unicode strings, distributed objects, timers, and more.

GNUstep Guile - A package that allows one to use the Guile scripting
language within GNUstep projects

JIGS - An interface to Java, that allows one to use GNUstep objects in
Java code and Java objects in GNUstep code.

This entire suite of tools and libraries, collectively called GNUstep
LaunchPad should allow developers to rapidly develop cross-platform
applications using a set of object-oriented tools and a well developed
API. Developers should be able to port applications from the
well-known MacOS X development system to GNUstep with almost no

RE: Bug in NSTextView delegate

Hi, thanks - I'm confused then - can someone check and report how does it
work on Apple Mac OS X ?

Is the notification sent only when text is changed there as well ?

Re: Problem with NSColor/NSString initialisation

I just tried your sample program and got the expected output (No
errors). This is with all the latest CVS code installed.
