Hello List
I'm working on an app where I have a NSTableView with one column
containing strings.
I want this column to automatically resize itself within the
ScrollView to fit the width of the widest string.
In order to do this I came up with the following code:
-(void)calculateCellTextAttribs{
NSFont* font = [[[[myTableView tableColumns] objectAtIndex:0]
dataCell] font];
myCellAttributes = [[NSMutableDictionary alloc] init];
[myCellAttributes setObject:font forKey:NSFontAttributeName];
}
-(float)stringPixelWidth:(NSString*) theString{
NSSize extent = [theString sizeWithAttributes:myCellAttributes];
return 1.1*extent.width;
}
-(void)updateTable{
[myTableView reloadData];
if([records count]){ //records is a NSArray of NSString
float maxWidth = 0;
int i = 0;
for(i = 0; i < [records count]; i++){
float tiw = [self stringPixelWidth:[records
objectAtIndex:i]];
if(tiw > maxWidth){
maxWidth = tiw;
}
}
[[[myTableView tableColumns] objectAtIndex:0]
setWidth:maxWidth];
}
}
The problem is that on very large strings sizeWithAttributes comes up
short [no pun intended]
Hence the 1.1 return multiplier in stringPixelWidth.
Does anyone know why this happens or if there is a simpler way to
achieve my goal?
Any help appreciated!
