Hi All, This is related to Phil Aldis's request for some suggestions.
Being no expert, I haven't the courage to reply under that heading :-)
Anyway, I have been implementing DWF's excellent DRAWLINE.pro into an image
processing tool. One drawback, I found was that there was no way to get the
information returned from the program for analysis done somewhere else. I
thought that if a KEYWORD was added, such as
drawline, image,DESTINATION_WIDGET_ID = tlb_of_another_widget
Then this tlb variable could be present in the info structure, then a pseudo
event can be sent to this tlb_of_another_widget. This pseudo event would
contain the coordinates of an ROI, for instance. (I haven't connected this to
CW_ZOOM yet, as someone on this group was trying, but I will be doing it soon)
I like using pre-written programs since they take care of a lot of messy
stuff like colors and sizing. But I like even better to leave them intact,
i.e. not have to change them to suit particular needs.
(Don't know anything about Pseudo-events? Might I recommend David Fanning's
book? )
