select point show info

[chrfi]

this is a request for the ability to click on a point in the main window or in the profile window and a pop up box to appear listing all the recorded data. this will allow the user to see the exact values rather than the slightly fuzzier graphically interpretations of these values.

the feature will display the closet point when several fall in the same location (so from the top down view this is the highest point)

Chris, what I need you to do is provide me with a method that will return a string containing the filename of a flightline if I pass it the number assigned to that flightline by the quadtree. You could possibly do it using a vector whose elements are numbered in a way that corresponds with the flightline numbers.

[chrfi]

I've added a method called getfilename to quadtree which takes a uint8_t which is the flight line number and returns a string which is the full path of the file. (needed to add a tiny get method to the loader classes as well to get the filename)

Thanks Chris. The feature now works, after a fashion. It fulfils its main purpose of identifying flightlines reasonably well as long as the lines do not completely overlap (i.e. as long as there is and area where a flightline is not overlapping with another).

Now works when dragging as well.

Have changed the feature (or, more accurately, fixed it slightly) by stopping it from falling back on point "0" of the bucket when it cannot select anything else. It will now correctly result in "0 0 0". This means it now behaves a lot better in overlap areas. There still appear to be problems getting it to select the correct point, however.

DONE! Finally. It now seems to work flawlessly, and does not cause crashes through race conditions any more.
