Window Manager

The wmWindowManager struct can be considered the parent of all user interaction. At its simplest you could think of it as the list of all the Windows, but in reality it contains much data about the current running state of the user interface. This includes which window is active and which is drawable, operators list, reports, jobs, key configs, undo stack, and much more.

Getting the Window Manager

It is a simple call to get the current Window Manager. In most cases you need it for a user-interactive purpose, so you can often avoid having to test the return for NULL. The exception to be aware of is when Blender is run headless from the command-line. You get the current window manager from the Context like this:

wmWindowManager *wm = CTX_wm_manager(C);
