[Openev-discuss] Legends

[Frank W. <war...@ho...>]

Folks, 

I have modified the legends dialog so that it will start a new column when
it gets to the bottom of the current window.  Resizing the window will cause
the legend to be reorganized again.  I do not currently try to make the legend
window wider if needed, as I am a bit worried about possible ramifications.

Note that my code for computing the width of columns is based on an approximate
width of 14pt characters, but in really the width varies depending on the
characters.  If you have a label of lots of capital `A's you will get a bit 
of overlap, and if you have a label of all '.''s you will get lots of extra
white space. 

The legend title isn't currently centered. 

We really need a way of finding out how big a given text object will be when
drawn in OpenEV, but it isn't critical for CIET. 

Let me know of any other problems. 

Best regards,
