I'm using the Font Panel via NSFont Manager to change text attributes
through a modal panel (in fact a sheet).
I can change the font OK, as using -setTarget: I can set the target of
the font manager to my modal panel. However, I never get the call to -
changeAttributes:, so all the stuff such as colour and shadow that the
Font Panel has doesn't function.
Is this a bug, or am I doing something wrong? If it is a bug, can
anyone suggest a workaround?
My code is pretty simple:
When my modal sheet is initialized, I set up the font manager thusly:
// establish the connection to the font panel and update it to match
the current font/text attributes
NSDictionary* textAttributes = [settings
objectForKey:kDKOMapGridHorizontalAnnotationTextAttributes];
NSFont* font = [textAttributes
objectForKey:NSFontAttributeName];
[[NSFontManager sharedFontManager] setTarget:self];
[[NSFontManager sharedFontManager]
setSelectedAttributes:textAttributes isMultiple:NO];
[[NSFontManager sharedFontManager] setSelectedFont:font isMultiple:NO];
(where 'settings' is a dictionary of a whole raft of things, including
the text attributes of the text I want to change via the font panel)
and my -changeFont: and -changeAttributes: methods look like:
- (IBAction) changeFont:(id) sender
{
// received changeFont message from font panel
NSFont* newFont, *oldFont;
NSMutableDictionary* textAttributes = [[mSettings
objectForKey:kDKOMapGridHorizontalAnnotationTextAttributes]
mutableCopy];
oldFont = [textAttributes objectForKey:NSFontAttributeName];
newFont = [sender convertFont:oldFont];
[textAttributes setObject:newFont forKey:NSFontAttributeName];
[mSettings setObject:textAttributes
forKey:kDKOMapGridHorizontalAnnotationTextAttributes];
[mSettings setObject:textAttributes
forKey:kDKOMapGridVerticalAnnotationTextAttributes];
[textAttributes release];
[self conditionallyPreview];
}
- (IBAction) changeAttributes:(id) sender
{
NSLog(@"received -changeAttributes: from <%@>", sender );
NSDictionary* textAttributes = [mSettings
objectForKey:kDKOMapGridHorizontalAnnotationTextAttributes];
NSDictionary* newAttributes = [sender
convertAttributes:textAttributes];
[mSettings setObject:newAttributes
forKey:kDKOMapGridHorizontalAnnotationTextAttributes];
[mSettings setObject:newAttributes
forKey:kDKOMapGridVerticalAnnotationTextAttributes];
[self conditionallyPreview];
}
The call to changeAttributes is never logged.
It seems as if [NSFontManager setTarget] applies only to the
changeFont: message and not to changeAttributes:. This appears to be a
bug, but there may be some good reason for it. Workaround?
