I noticed a strange behaviour in TPrintPreview, but I'm not sure if this is a bug.
I use the TPrintPreview as a preview for a TSimpleGraph component. To create the graphic for TPrintPreview I took the following line:
- Code: Select all
Mainform.SimpleGraph.Print(PrintPreview1.Canvas, Rect(0, 0, Mainform.SimpleGraph.GraphBounds.Right, (Mainform.SimpleGraph.GraphBounds.Bottom)));
Here's the problem: I insert about 20 nodes (in line) in TSimpleGraph; each one containing a metafile. From a certain position TPrintPreview only displays the border of the nodes but not the metafiles. If I insert a bitmap instead the problem doesn't occur.
Does anyone have an idea concerning this effect?
