Gl.IsEnabled (gb.opengl)
Static Function IsEnabled ( Capacity As Integer ) As Boolean
Parameters
- cap
-
Specifies a symbolic constant indicating a GL capability.
- index
-
Specifies the index of the capability.
Description
Gl.IsEnabled returns Gl.TRUE if
cap is an enabled capability
and returns Gl.FALSE otherwise.
Boolean states that are indexed may be tested with
Gl.IsEnabledi.
For
Gl.IsEnabledi,
index specifies the index of the capability to test.
index
must be between zero and the count of indexed capabilities for
cap.
Initially all capabilities except Gl.DITHER are disabled;
Gl.DITHER is initially enabled.
The following capabilities are accepted for
cap:
