I have a NSTextFieldCell that I wish to display with middle vertical alignment. Thanks to an older question here and a blog entry I have two working solutions.
However, both solutions seem to squash my ability to set the cell as right aligned. Can anyone help me make either of these solutions support both forms of alignment?
Here is the code for one solution:
@implementation MiddleAlignedTextFieldCell
- (NSRect)titleRectForBounds:(NSRect)theRect {
NSRect titleFrame = [super titleRectForBounds:theRect];
NSSize titleSize = [[self attributedStringValue] size];
titleFrame.origin.y = theRect.origin.y - .5 + (theRect.size.height - titleSize.height) / 2.0;
return titleFrame;
}
- (void)drawInteriorWithFrame:(NSRect)cellFrame inView:(NSView *)controlView {
NSRect titleRect = [self titleRectForBounds:cellFrame];
[[self attributedStringValue] drawInRect:titleRect];
}
@end
The alternative solution is (obtained from this blog):
@implementation RSVerticallyCenteredTextFieldCell
- (NSRect)drawingRectForBounds:(NSRect)theRect
{
NSRect newRect = [super drawingRectForBounds:theRect];
if (mIsEditingOrSelecting == NO)
{
// Get our ideal size for current text
NSSize textSize = [self cellSizeForBounds:theRect];
// Center that in the proposed rect
float heightDelta = newRect.size.height - textSize.height;
if (heightDelta > 0)
{
newRect.size.height -= heightDelta;
newRect.origin.y += (heightDelta / 2);
}
}
return newRect;
}
- (void)selectWithFrame:(NSRect)aRect inView:(NSView *)controlView editor:(NSText *)textObj delegate:(id)anObject start:(int)selStart length:(int)selLength
{
aRect = [self drawingRectForBounds:aRect];
mIsEditingOrSelecting = YES;
[super selectWithFrame:aRect inView:controlView editor:textObj delegate:anObject start:selStart length:selLength];
mIsEditingOrSelecting = NO;
}
- (void)editWithFrame:(NSRect)aRect inView:(NSView *)controlView editor:(NSText *)textObj delegate:(id)anObject event:(NSEvent *)theEvent
{
aRect = [self drawingRectForBounds:aRect];
mIsEditingOrSelecting = YES;
[super editWithFrame:aRect inView:controlView editor:textObj delegate:anObject event:theEvent];
mIsEditingOrSelecting = NO;
}
@end
