One of the screenshots in your gallery page apparently shows a gantt chart. Is that really done with the flowchart control?  If so, how can I create a header which stays immovable on the screen while the rest of the chart is scrolled up or down?

Thanks

I don't know whether that's a Gantt chart, but I can think of couple ways to draw immovable headers.

1) with a custom drawing. I.e. put a helper Box in the foreground by calling ZTop. Make it custom drawn by setting its CustomDraw property to cdFull. Handle the CustomDraw event and draw the headers starting from the flowchart's ScrollX and ScrollY coordinates. Thus the headers will always be drawn from the top-left point of the flowchart. You might want to set Locked = true to prevent users to select the 'headers' box.

- or -

2) Use several helper boxes to represent the header. Handle the Scroll event and move those boxes relative to the new ScrollX/ScrollY position, so they won't change their position visually.

They might be more ways to implement that, I'll ask the devs around whether they could think of something easier.

Thank you for the suggestions gentlemen.

Custom drawing with GDI+ in VB is impossible task for me So now I use a table to draw the header, there is just one row, and each cell in that row represents a week. In addition I set the caption height to 0.

I found that ClientToDocPt function and use it to calculate the Y position where the table is moved in response to flowChart_Scroll. Now my gantt works very much as required.

This control of yours is great!
