connectCreateContext
fun connectCreateContext(connectFlags: <Error class: unknown class> = ConnectFlags(0u), handler: () -> <Error class: unknown class>): <Error class: unknown class>
Emitted when the widget is being realized.
This allows you to override how the GL context is created. This is useful when you want to reuse an existing GL context, or if you want to try creating different kinds of GL options.
If context creation fails then the signal handler can use method@Gtk.GLArea.set_error to register a more detailed error of how the construction failed.
Parameters
connectFlags
A combination of ConnectFlags
handler
the Callback to connect. Returns a newly created GdkGLContext; the GtkGLArea widget will take ownership of the returned value.
