Re: TPolygonShape
Thank you Yeray That does work, but only temporarily. If you perform any other change to the TTree, such as turn off the grid etc. then the image reverts back to a rectangle. Additionally it does weird things to other TTreeNodeShapes, such as causing the images not to display within all other shapes...

TPolygonShape
Is it possible, at this time, to apply an image to a TPolygonShape, with imagealignment of iaCenter and have the image fill out just within the boundaries of the polygon, rather than creating a rectangle?

Connection Issues
With regards the connection issue, once I save the TTree to stream and reload it from the stream, the connections are no longer visible. Yet I know the components are there, because in designer if I try to add a connection between the same two nodes, I get an error message that states "A component n...

The Lost Children
Thank you for the insight into the NoOwnerShapes property. I could not find this documented in the help manual. I have moved a little further. A TTree has nodes and child nodes added at runtime. procedure Form1.SaveMyTree(Sender : TObject); begin Tree1.NoOwnerShapes:= false; SaveTreeToStream(Tree1,s...

TTree Save to Stream
This is just getting an exercise in frustration. I see in the help that there is a LoadTreeFromStream procedure. Great. However there is no documented SaveTreeToStream. But it exists. So that is good, now I can save the Tree to a database and then reload it. However when I load it I discover that it...

SaveToStream and Transparency
I can add a TTreeNode Shape TTreeNodeShape.Image.Assign(SomeBitmap); TTreeNodeShape.Image.Transparent:= true; TTreeNodeShape.ImageAlignment:= iaCenter; All is good , the image shows the background. However if I SaveTreeToStream(MyTree,strm) or SaveTreeToFile(MyTree,'C:\mytree') and then reload the f...

Hi Tom Thanks for the reply I am using the TTree components for users to map out farms and overlay building, pens and other features, using TTreeNodeShapes. This is all working very well. The background is an overhead image of the farm from Google Earth that is used as a template. Some features on t...

Draw on Canvas
If on the mouse up event I use
Tree1.Canvas.Draw(X,Y,Bitmap)
this works fine until I do anything else, such as turn on or off the grid, go to add a TreeNodeShape, etc. then the image disappears. How can I save the canvas?

Polyline/Polygon question
I have BDS 2006 running on XP sp 2 . I create a form, drop a TTree on it then double click on the TTree component to open the editor. I select either the polygon or polyline tool. Then I click in the editor field and start laying out my polygon or polyline. How do I tell the mouse I have done with t...

Shadow not showing
Probably a simple answer that I cannot figure out. I cannot get the shadow to appear in an Imageshape. Everything works fine but no shadow. Code as follows: procedure AddShape1 (Bitmap1 : TBitmap , TreeX,TreeY : integer); var V : TImageShape; begin With Tree1 do begin V:= TImageShape.Create(Tree1); ...
