Macro rendering in main window
I'm a beginner of KLayout and would like to start some post-processing some GDS files.
Would it be possible to render in the mainwindow all cells, layers and polygons creation using a macro?
Using this code I can create a layer, a cell, but the layer and the box are not showing up, though they get created when opening the saved gds file.
module MyMacro
include RBA
mw = RBA::Application::instance.main_window
ly = mw.create_layout(0).layout
layout_view=mw.current_view
dbu = 1.0/ly.dbu
puts "Database Unit:" + dbu.to_s
tc = ly.create_cell("TOP")
#modify layer index
li = ly.insert_layer(RBA::LayerInfo::new(1,0))
#adding a box
tc.shapes(li).insert(RBA::Box::new(0, 0, 1000, 1000))
layout_view.zoom_fit
ly.write("c:/Users/mb_000/Klayout/1.gds")
end
Why don't the layer and the polygon show on the main window output?

Add this near the end:
This is equivalent to right-clicking on the layer list and choosing "Add other layer entries" (try it, with your current script).
Why do you need to do this? The layers list does not (indeed, cannot as far as I know) update when you add or remove or modify layers programmatically. See Matthias's explanation here, scroll to the last post.
But there is a second problem: "TOP" is not showing as the top cell. For a short-term workaround, run your script and then center-click on the "TOP" cell in the cell list on the left of the main window. Or, equivalently, right click and "Show as new top". Now you can see your cell also.
I searched but couldn't find a way to do that "show as new top" function programmatically. Probably Matthias has a way..

Also check out E4K, which, funnily enough, has an example to draw a box on a new layer.
Feel free to contribute your own example scripts to E4K as you learn scripting -- E4K is a bit sparse right now... I just haven't had the time to add a huge number of examples to it.
Hi David,
thanks at lot again for your support!
Best regards,
Matthias
