length and measure

[Ralph]

Hi Mindset,

you could try something like this:

SizeF mySizeF = graphics.MeasureString(incomingpath ,textFontBold);
Size mySize = Size.Ceiling(mySizeF);
Point myPoint = new Point(ChartControl.Bounds.Left, ChartControl.Bounds.Top);
Rectangle rectangle1 = new Rectangle(myPoint,mySize);
graphics.DrawRectangle(borderPen,rectangle1);

Let me know how that works

Didn't know you could do that

Interesting that Point can take x and y cords together.

However like you I would prefer to work with integers so how do I convert

my take is that I declare 2 points for the X and Y co ords.
Then a height which I shall take off the text.height - but it all comes back to the width which is a SizeF or a Size but not an integer?

I feel a lightbulb moment coming but right now I am in the darkest hole
I feel quite annoyed asking these questions really - most things I have been able to work out but this has just got me.

Hi Mindset,

You can derive the width and heigth integers from the Size struct.
int height = mySize.Height
int width = mysize.Width

Regarding to your rectangle you need to make a decision between a Point() and a Size() or 2 coordinate-points. What you always have is a Size(). Then you either construct a Point() as in my example or you calculate the second coordinate-point like pointx+width and pointy+height.

Many thanks for your patience Ralph.

I believe I have got the rudiments of it now.
Width and height are properties of the Size - Doh! a real Homer moment.

I could have pointed out that earlier, but sometimes it is not easy for me to recognise through the internet what exactly is the core of the issue at the other end of the cable.

Btw, the other way around is also a good looking solution. You could instantiate a Point struct for your class and then you load it with the x nad y coordinate and finaly use the Rectangle(Point, Size):

Point myPoint = new Point();
...
myPoint.X = pointx
myPoint.Y = pointy
Rectangle rectangle1 = new Rectangle(myPoint, mySize)

You are now spoilt for choice, is this expression correct?

[Mindset]

Spoilt

Yes I am now spoilt for choice.
Your command of English is excellent!

Going so well ...

and then thud...
I have spent most of Sunday afternoon trying to solve this riddle.. and I am just not getting it?

How do I get my PointF or even better the Y co ordinate to place my rectangle?

private StringAlignment BoxX = StringAlignment.Near;
private StringAlignment BoxY = StringAlignment.Near;


//			case BoxPosition.BottomLeft:
//	
//			BoxX = StringAlignment.Near;
//			BoxY = StringAlignment.Far;
//			line1locale = 32;
//			line2locale = 16;
//			break;
//		}

line 1 and line 2 are built using StringBuilder and then I use DrawTextAbsolute for the 2 separate lines.

I measure my largest string

	mySizeF =  graphics.MeasureString(str1,textFontBold);	
	mySizeF2 = graphics.MeasureString(str2,textFontBold);

       Size mySize = Size.Ceiling(mySizeF);
       Size mySize2 = Size.Ceiling(mySizeF2);

	int myWidth  = Math.Max(mySize.Width,mySize2.Width);
        int height = (textFontBold.Height * 2) +5;

I am then completely confused about how to get the Y start co ordinate.

Point point1 = new Point(line1locale) doesn't give me the correct value.

I prefer the integer route so
If I manually use ChartControl.CanvasTop +2 - that works
but the bottom is Chartcontrol.CanvasBottom - 289 - I only got this by manually deprecating nos until it looked right.

There has to be a simple way to get this point as the program has already placed the text - but how do I recover this value???

Hi Mindset,

not sure what exactly your problem is, so I try my 2 cents.

Your point-structure consists of 2 coordinates, a X and a Y. I would set that in relation to the Canvas.X and Canvas.Y or Canvas.Top and Canvas.Left respectively. These pairs all describe the upper left corner of an rectangle and you could set these pairs into relationship easily.

That means:
Point.Y = Canvas.Top: Your rectangle is placed at the top edge of your canvas.
Point.Y = Canvas.Bottom - myRectangle.Height: Your rectangle is placed at the bottom edge of your canvas.

Btw, moving shapes around on a canvas is an exciting untertaking
