Problem with the graphic point navigation #17

Closed miguelmoreto closed 6 years ago

miguelmoreto commented 7 years ago

If the user click on the simulation graphic, this feature adds a circle over the graphic that can be used to view the respective coordinate and navigate throughout all the points using the mouse scroll.

But this feature works only if the user does not use de zoom function.

Using the binary version of Labcontrole, after the user used the zoom for the first time this new feature no longer works afterwards. Only after re-open the program.

@andidevel I appreciate if you can check this. But only if you have time, it is not urgent.

In fact, this function works only while not "zooming" or "panning", but, if you "uncheck" the button you can use the feature again, at least, in my tests, running on Linux. I'll check this, though.

Done! I did a new pull request, #18, fixing the problem.

Actually, it wasn't a "problem". I did that to avoid mouse event conflict with NavigationToolBar super class, since I didn't know very well how this class works. But I agree, it was kind annoying use zoom or pan and lose the navigation until release the buttons (exiting from Zoom/Pan modes) on navigation toolbar.

Thanks a lot @andidevel !

I'm working with porting the LabControle2 to Python 3 and pyQt5. It is almost done.

Best regards,
