Description Mick Curtis 2006-07-12 14:23:48 UTC
Hello, I wrote some notes which make sense to me at least. They describe how to build a small basic flowchart......
It might 'bring together' many of the basic ideas of the documentation.
You do show a small flowchart diagram already in your Help but this explanation explores the most basic steps for doing something like that. Maybe it could be edited into a Help article.


Making a simple Flowchart

Note: If at any time, an object disappears or partially disappears then try View..Redraw . Otherwise, if you have removed an object, use Edit..Undo  to bring it back.

I want to have an ellipse and I want to contain text inside it.
So I put an ellipse on the canvas and then I put a text object on the canvas and start typing a caption;
then I drag the text into the centre of the ellipse. I turn off 'snap to grid' so that the text will align 
just where I want it.

Now, I want the ability to drag the ellipse and the text as if they are one 
object; but at the moment, if I drag one, the other object does not drag as well.
So, I select both objects and, at the menu, do Objects..Group. Now they will drag together as if they are one single item.
[Side Note: 'Ungroup' would undo the grouping of selected items.]

I create another ellipse and caption in a similar way.
I put a line object between them (its properties make it looks like an arrow). 
Now I drag the first ellipse but the arrow does not travel with it:
the arrow is not glued to the ellipse and so the arrow relationship breaks.
So I need to connect each end of the arrow to each of my ellipses.
I do this by right-clicking the line and clicking 'Add Connection Point'.
Now, if I drag the arrow as far as ellipse 1, a red color indicates that they have glued together;
and if I drag the other end of the arrow to ellipse 2, again, a red color shows that they have glued together;
so now I can move an ellipse and its arrow line travels with it.
Note: All of this assumes that all of these objects occur in the same layer.
Note: You can also use image objects and browse to a bitmap that suits your theme; then you can use images as well as basic box/ellipse shapes. In fact, I saved some clipart as a bitmap and then I was able to use it within a diagram that I was making.

Regards,

A group does not have connection points, so you cannot get the line to attach.  This is part of a larger problem with the current group system that I'm working on fixing (basically, grouped objects are removed from the diagram and held by the group object, so a number of things that assume objects being in the diagram don't work).  For your particular example, you may have more luck with the flowchart ellipse object.
