OS X Lion 10.7.5, Xcode 4.6.3, Document based app for OS X. The title states my
problem.
NOTE: IB is not used for anything other than a default empty nib. Views etc are
all done programmatically.
The 3 x 3 matrix is displayed with the attributed titles and alternates but
left aligned.
I am unable to change this behaviour
However if I use the setTitle and setAlternateTitle methods (using strings
instead of attributed strings) everything works.
I had hoped to use italic AlternateTitles hence the code below but which does
not centre align the title in the Cell.
I'd appreciate any help in telling me where I've misunderstood or coded badly.
Thanks. Peter
My Cell sub-class of NSButtonCell init method does the following:
- (id)init {
self = [super init];
if (self) {
// Set the cell attributes
,,,,,
[self setAlignment:NSCenterTextAlignment]; // <=== NOTE
// Set the Cell title & alternate title
NSFont *font = [NSFont fontWithName:@"Helvetica Neue" size:64.0];
NSDictionary *attr = [NSDictionary dictionaryWithObject:font
forKey:NSFontAttributeName];
NSAttributedString *aTitle = [[NSAttributedString
alloc]initWithString:@"XY"attributes:attr];
[self setAttributedTitle:aTitle];
NSFont *iFont = [NSFont fontWithName:@"Helvetica Neue Italic"
size:64.0];
NSDictionary *iAttr = [NSDictionary dictionaryWithObject:iFont
forKey:NSFontAttributeName];
NSAttributedString * iAtitle = [[NSAttributedString
alloc]initWithString:@"AB"attributes:iAttr];
[self setAttributedAlternateTitle:iAtitle];
}
return self;
}
The initialized Cell is used as the prototype for initializing my Matrix
sub-class of NSMatrix:
This is done in the Document.m method windowControllerDidLoadNib
// Other prep stuff
----
// Create the Matrix and set it's attributes
Cell *protoCell = [Cell new]; // temp for initing the matrix
_theMatrix = [[Matrix alloc]initWithFrame:theMatrixFrame
mode:NSListModeMatrix prototype:protoCell
numberOfRows:3 numberOfColumns:3];
// Set various attributes
-----
[_theMatrix setAlignment:NSCenterTextAlignment];
[theContentView addSubview:_theMatrix];
