Do you have anykind of sample that is like a movie maker time line? Basically the functionality is you have several rows and you can drag and drop an object on the row and manipulate the object to cover some duration. Just a question.
Thanks,
Courtney

The grid control is good because it already has many ready-to-use grid cell classes. But real time-line or history board can be long and should be scale-able. We have coded an interesting scrollable control a few years ago:

TestGraph2.zip

It displays dots and lines looking like chart but this is not the main feature. It uses float or double values instead of int or long values for specifying scrolling ranges and positions. You can see slider controls near each scroll bar and they allow you to scale scrollable ranges or magnify viewed data. We believe this is what really should be present in timeline. Our CExtFloatScrollWnd class uses OpenGL like normalized floating point values in range 0.0 ... 1.0. It’s possible to re-format text labels on each axis, remove chart lines, disable point drag-n-dropping and add everything else what make this window looking like timeline. Of course, we can help you to do this but it looks like we need more details about this task. What will be represented in X and Y axes? We need some more detailed data type descriptions, their ranges etc.

If the time line is not unlimited, then it can be reproduced using a grid window with or without custom painted cells or grid areas. But generally this task is very specific to a particular project and requires a very detailed discussion on the time line control’s behavior and data shown on it. Unfortunately we have no stand alone time line control.

Yea i figured it would be very customizable. Do you have something like a story board? I know I can use a grid cell. I was looking for something that had a linear direction basically so they couldn’t drag and drop to any cell but left to right or only top to bottom?
