Double-clicking on a
.pxr file will open it in an editor. The type of editor it
opens in will depend on the root type (video, audio, gui, etc.). Remember that the
project the file belongs to must have been built so that the root shows up in the
Hub Manager before the file can be edited, otherwise the editor will contain a
message asking you to build the project.
At the top-right of the editor region are four icons. Three of these allow you to switch between open editors. The maximize icon allows you to enlarge the editor area, minimizing all the other windows to the sides and providing more workspace.
All editors have their own toolbar, which contains at least two buttons. The play button toggles whether the root is playing / active. The root properties button opens a window allowing you to set properties of the root component (such as video resolution and frame-rate). Not all root properties can be set while the root is playing.
You can save a
.pxr file at any time when the editor is active. You will also be
prompted to save whenever the hub is restarting or when a root is removed from the hub.
Due to its distributed architecture, PraxisLIVE does not attempt to track all changes
so will always prompt you to save.
