Hai,
I have made some changes in sketch example. I am a beginner in cocoa. Our
desired out put is to display the width of text at the mid point of a
line.
I gave these in the Line.m of sketch
- (NSBezierPath *)bezierPath {
NSBezierPath *path=[NSBezierPath bezierPath];
NSRect bounds = [self bounds];
//if(keyDown)
//{
if ([self startsAtLowerLeft])
{
[path moveToPoint:NSMakePoint(NSMinX(bounds), NSMaxY(bounds))];
x1=NSMinX(bounds);
y1=NSMaxY(bounds);
[path lineToPoint:NSMakePoint(NSMaxX(bounds), NSMinY(bounds))];
x2=NSMaxX(bounds);
y2=NSMinY(bounds);
}
else{
[path moveToPoint:NSMakePoint(NSMinX(bounds), NSMinY(bounds))];
x1=NSMinX(bounds);
- Ignored:
y1=NSMinY(bounds);
[path lineToPoint:NSMakePoint(NSMaxX(bounds), NSMaxY(bounds))];
x2=NSMaxX(bounds);
y2=NSMaxY(bounds);
// [self TextDisplay];
}
//}
NSPoint midPoint;//,locationText;
width=sqrt((x2-x1)*(x2-x1) + (y2-y1)*(y2-y1));
midx = (x1+x2)/2;
midy = (y1+y2)/2;
midPoint.x=midx;
midPoint.y=midx;
NSLog(@"width is:%i \t x1,y1==%i,%i \t x2,y2==%i,%i
",width,x1,y1,x2,y2);
NSLog(@"Middle point is:%i ,%i",midx,midy);
[self drawRect:bounds];
/*
NSPoint midPoint,locationText;
width=sqrt((x2-x1)*(x2-x1) + (y2-y1)*(y2-y1));
midx = (x1+x2)/2;
midy = (y1+y2)/2;
midPoint.x=midx;
midPoint.y=midx;
NSLog(@"width is:%i \t x1,y1==%i,%i \t x2,y2==%i,%i
",width,x1,y1,x2,y2);
NSLog(@"Middle point is:%i ,%i",midx,midy);
*/
return path;
}
-(void)drawRect:(NSRect)rect
{
NSString *message= [NSString stringWithString:@"Hai"];
NSMutableDictionary *attributes = [ NSMutableDictionary dictonary];
NSRect textBounds=NSZeroRect;
NSRect bds = [self bounds];
textBounds.size=[message sizeWithAttributes:attributes];
textBounds.origin=NSMakePoint((bds.size.width-textBounds.size.width)/2.0,(bd
s.size.height - textBounds.size.height) /2.0);
[message drawAtPoint:textBounds.origin withAttributes:attributes];
}
