Right! But I would like to scroll vertically instead of horizontally. Moving the drawing everytime it hit the window limits would be a lot of extra logic.

The train track length will be dynamic and rendered based on different map files that are fed to the program, so I can't assume it will fit in the initial window ie.

window with tracks extending outside of it

Window / Using Views for Multiple Levels

« on: May 01, 2020, 05:49:29 pm »

I'm looking to display a train track that extends horizonally out of the window. I would like to display the track as wrapping, and thus be able to scroll up and down to view the full length of the track - instead of including logic that would break the track up as it is rendered.

I would think that I could define a second view which contained the track outside the window, and then set a viewport stacked under the default view:

View view1 = getDefaultView();                             //contains first portion of track
View view2(offscreen  track x, offscreen track y);    //contains second portion of track

view2.setViewport( 0 , offset from view1.y);           //display second portion of track underneath first portion
                                                                          //scroll down to view this portion

I've consulted:

and a few other threads to no avail.

Thanks for any input!
