README

        
GX is an API built on top of the XCB API which isn't so raw, is object orientated and is a tiny bit more liberal about utility code; just not libX11 liberal.

Like XCB, GX is all auto generated based on the XCB XML protocol specs.

Brief comparison with XCB:

Object orientated:

- Connection

- Screen

- Drawable

  - Window

  - Pixmaps

- GContext

- Cookie

Signal based event delivery.

Get notification signals from cookies when replies/errors have been received from the server.

Less emphasis on multi threading support, mor on on single threaded mainloop based event dispatching.

GErrors for all X protocol errors.

The recommended way to use GX is to take advantage of the cookie reply notifications so your programs dont need to block waiting for responses, but GX also provides a very convenient synchronous API too. This should be easier to port xlib code too than directly to XCB, and is useful for writting easy to read utilities where performance is a non-issue.

The GX API passes struct types by-ref instead of by-value.

GXMaskValueItem provides some safeguards for setting up value-mask and value-list data which is fairly error prone when using raw XCB.

- Though it might be worth going further and generating well typed structs if possible.
