Hi All,
This week I worked at preview function. I am trying to add the display from which user is supposed to select the point that is the centre of the smaller region of preview. Actually I used a customized class inheriting from GMFrame class (wxgui.py) and wx.Frame, and tried to draw the DEM map with a MapLayer class (render.py). This solution doesn’t work properly, because it raises a new Layer Manager + Map Display, but doesn’t draw the DEM in the canvas. (The code has been committed if someone is willing to test).
Anyway i figured out that it’s not the best solution, because it raises a new Layer Manager + Map Display, and I wanted just a Map Display instead. So I am currently trying to use the classes in mapdisp_window.py. This is not a piece of cake, as I am failing all my tentatives, and got fairly stuck at the moment. My problem is essentially that I get no errors but no Display raises. I didn’t find any answer reading the documentation [0].
Thanks,
madi
