Help rotating graphic created using guictrlcreategraphic()

[ankitstr]

Hi all,

I am working on a 2D graphical simulation program where there is like a compass pointer represented by a line drawn using guictrlcreategraphic() function, but if i try to draw a line again on the same graphic, it draws another line without removing the previous one. I don't want to delete the graphic as it causes the whole GUI form to refresh and since i am updating the pointer several times per second it is not acceptable. I need this working for my final year project at University. Any help would be really appreciated.

Thanks in advance,

Ankit

Hi

Check out the analog clock examples in the examples forum. I think they solve this problem by not deleting the line....just covering it up. If you remove the backgrounds on this clock you will see the innerworkings.

thanks for the reply. But I have tried covering it up, its just that I have a graphic below it with dynamic background, so I actually needed to somehow make the previous line invisible if possible.

I'll still try doing it again, maybe if I somehow match the background with the underlying graphic, it might work.

Have a look at UEZ' meters here. They give a really excellent example of what I think you want.
