Can we draw a gantt chart in a detail band

rbuser

I need to draw a gantt chart bar for each record in the detail band.
The gantt chart bar's start and end length depends on a field's value.

I cannot find any canvas property in any RB control nor detail band. Does
that mean it is not possible to custom draw a control in RB?

Thanks a lot in advance.

Dennis,
throw a TppImage in the detail band
and put the gantt chart into that

One option is to draw to the canvas of a TImage object on the form in the
detail band's OnPrint event. Then transfer the picture of the TImage into a
TppImage in the detail band, i.e. ppImage1.Picture.Assign(Image1.Picture).
Use Image1.Canvas for rendering. Also make sure to either size the TppImage
properly in advance or enable it's Strech property.

I have partial success with the method you mentioned.
When I try to write (i.e.g Canvas.TextOut), the font looks ok on the screen
but then when assigned to the TppImage, it looks rough. I believe it's
because the resolution on screen is lower than that of the printer.
If I try to scale it, I will have to scale the Font size as well. I am
afriad that will have different scaling effect from other line/rectangles I
draw on the canvas.

The best way is to directly draw on the targeted TppImage. Is that possible?

There is a Paintbox component which you can drop in the report. See our
