Hello,

I am trying to handle Keyboard and Mouse events of GLUT in my program. It seems however that these are not handled at all. My program runs well on a Windows machine. But none of the events of keyboard or mouse are handled.

I am using Xcode, have included Opegnl framework and glut framework (and glut works I guess, since a window is created using glut and initialization etc. also works).

Following is a sample code that am trying to run:

Code:
#include <stdio.h>
#include <GLUT/glut.h>

GLdouble X = 0.0, Y = 0.0;
GLdouble thetaX = 10.0, thetaY = 10.0;

void mouseFunc(int button, int state, int x, int y)
{
	if (button== GLUT_LEFT_BUTTON) {
		X+=0.2;
		Y+=0.2;
		printf("Moving up...\n");
	}
	if (button == GLUT_RIGHT_BUTTON) {
		X-=0.2;
		Y-=0.2;
		printf("Moving Down...\n");
	}
	glutPostRedisplay();
}

void normalKeys(unsigned char key, int x, int y)
{
	switch (key) {
		case 'u':
			X+=0.2;
			Y+=0.2;
			printf("Moving Up...\n");
			break;
		case 'd':
			X-=0.2;
			Y-=0.2;
			printf("Moving Down...\n");
			break;
		case 27:
			printf("Exiting");
			exit(1);
			break;
		default:
			printf("Key pressed does not have a meaning....");
			break;
			
	}
	glutPostRedisplay();
}

void idle()
{
	
	glutPostRedisplay();
}

void renderScene(void) {
	glClear(GL_COLOR_BUFFER_BIT);
	glColor3f(1.0f, 0.5f, 0.5f);
	
	
	glMatrixMode(GL_MODELVIEW);
	glLoadIdentity();
	glTranslatef(X, Y, 0);
	glRotatef(thetaX, 1.0f,  0.0f, 0.0f);
	glRotatef(thetaY, 0.0f, 1.0f, 0.0f);
	glutSolidSphere(1.0, 20.0, 20.0);
	glFlush();
}


int main(int argc, char* argv[]) {
	glutInit(&argc, argv);
	glutInitDisplayMode(GLUT_DEPTH | GLUT_SINGLE | GLUT_RGBA);
	glutInitWindowPosition(100,100);
	glutInitWindowSize(320,320);

	glutIdleFunc(idle);
	glutMouseFunc(mouseFunc);
	glutKeyboardFunc(normalKeys);
	glutCreateWindow("Glut try");
	glutDisplayFunc(renderScene);

	
	glutMainLoop();
	
	return 0;
}

What can be wrong or am I missing something?
Would appreciate any help!
Thanks!
