TAnnotationTool AutoSize

Post by franckgar » Fri Dec 10, 2004 4:00 pm

Hi!

I have a pb when I set the property AutoSize of TAnnotationTool to TRUE .

The values returned by the properties height and width of the TAnnotationTool are always wrong (even TAnnotationTool.Shape.height and TAnnotationTool.Shape.width).

So how can I know the height and width of the TAnnotationTool ?

Thanks in advance.

Hi ,

you can read TAnnotationTool->Shape->ShapeBounds rectangle to
get annotatiton tool bounding rectangle. The rest is easy :

TRect r = AnnotationTool->Shape->ShapeBounds;
Width = r.Right - r.Left;
Height = r.Bottom - r.Top;

I wrote too quickly ... the solution you gave to me is not good because r.Right and r.Bottom are always null !

Any ideas?

Hi,

this depends in which event you place the code, it works fine placing it in the OnAfterDraw event.

Hi Pep,

I tested the value of AnnotationTool->Shape->Right and AnnotationTool->Shape->Bottom in the OnAfterDraw event and I always found 0 (perhaps due to the property AUTOSIZE = TRUE).

The only solution I have found is to recalculate manually the height and width of the AnnotationTool, like the function MultiLineTextWidth() into the unit TeEngine.pas. For the moment this solution is acceptable for me.

Bye
