Showing One of My Open Windows as Full Screen

Would this solution work for you?

East Docked Slide-Out - How to?

Create a floating window, and “dock” it to wherever you want it Make it not opaque. Remove all mouse listeners from the window. Create your menu, either in a group or template, place on this non opaque window Use system.gui.transform to move in and out

East Docked Slide-Out - How to?

Looks like I didn’t do my research; system.gui.transform() requires that the component to be manipulated is an Ignition component, which prevents you from modifying more basic Java objects like the window/root container. You can call setSize explicitly - what you’d have to do is shrink the ‘main’ window, and ‘grow’ the docked window to compensate.
