|
329 | GLUT is a quite old library and it is difficult to ensure proper | |
|
330 | integration within IPython since original GLUT does not allow to handle | |
|
331 | events one by one. Instead, it requires for the mainloop to be entered | |
|
332 | and never returned (there is not event a function to exit he | |
|
333 | mainloop). Fortunately, there are alternatives such as freeglut | |
|
334 | (avaialble for linux and windows) and the OSX implementation gives | |
|
335 | access to a glutCheckLoop() function that blocks itself until a new | |
|
336 | event is received. This means we have to setup a default timer to | |
|
337 | ensure we got at least one event that will unblock the function. | |
