For the Laszlo developers amongst my readers…
I wrote a little interactive debugging tool that I have found very useful in my own app development. It lets you inspect the view hierachy and see and modify key properties (bgcolor, position, size, visible).
You can try it here. You can change bgcolor and view position. Click on the x/o to toggle visibility. Click on ‘…’ will send the instance to the debugger, where you can click on it for further inspection.
You can download a zip of the source from the mylaszlo forum.
