This methods sets the PyOS_InputHook for GLUT, which allows | ||||
the GLUT to integrate with terminal based applications like | ||||
IPython. | ||||
Nicolas Rougier
|
r4808 | GLUT is quite an old library and it is difficult to ensure proper | ||
Nicolas Rougier
|
r4806 | integration within IPython since original GLUT does not allow to handle | ||
events one by one. Instead, it requires for the mainloop to be entered | ||||
Nicolas Rougier
|
r4809 | and never returned (there is not even a function to exit he | ||
Nicolas Rougier
|
r4806 | mainloop). Fortunately, there are alternatives such as freeglut | ||
Nicolas Rougier
|
r4808 | (available for linux and windows) and the OSX implementation gives | ||
Nicolas Rougier
|
r4806 | access to a glutCheckLoop() function that blocks itself until a new | ||
event is received. This means we have to setup a default timer to | ||||
Nicolas Rougier
|
r4808 | ensure we got at least one event that will unblock the function. We set | ||
a default timer of 60fps. | ||||
Nicolas Rougier
|
r4806 | |||
Nicolas Rougier
|
r4808 | Furthermore, it is not possible to install these handlers without a | ||
window being first created. We choose to make this window invisible and | ||||
Nicolas Rougier
|
r4809 | the user is supposed to make it visible when needed (see gui-glut.py in | ||
Nicolas Rougier
|
r4808 | the docs/examples/lib directory). This means that display mode options | ||
Nicolas Rougier

r4809 | are set at this level and user won't be able to change them later | ||
