Hi
I am using GEF to draw so chart sort of display. The chart is expected to
accept the values which are quite long and on those values a "Figure" is
expected to be drawn. For example, at the "x" position equals to
'971997000' I want to draw a RectangleFigure. I am doing this by calling
the method:
"figure.setLocation(new Point(x,y));"
The Point constructor doesn't accept a value other than int. And the int
value is going out of range in my case and the figure object is not
getting displayed.
Can anyone please tell me a solution for this ? What should I do to get
the objects withing the limit ?
Thanks!
Krayon

Hi Pratik,
I tried to perform some similiar action with the "Shapes" example in GEF.
Here is what I did:
I created a '.shapes' file and drew a Rectangle from the drawing palette.
Then from the Properties View, I set the following properties for the
Rectangle:
Height: 40
Width: 50
X: 1000000000
Y: 100
After setting these properties I started reducing the 'Width' of the
rectangle. When I went further below the value "33" the rectangle seems
to be disappear. It is not even getting highlighted when selected from
the Outline View. Is there something that I am doing wrong?
[ I have just replicated the steps that were posted in one of the earlier
query on this newsgroup. ]
If such a large value is not supported and there is a need for such a
large value, what should be an ideal way to do this? Scaling the graph
will lead to certain other problems. Please provide some suggesstion.
Thanks,
Krayon

You'll have to store your large data in some model and show the user a
scaled down version of it that fits within the limitations of a Canvas.
