ortho prob

OpenGL OpenGL: Basic Coding

can anyone tell me what is wrong with this code?

  
void selectionChoice(int x, int y)
{
	unsigned int selectBuf[1024];
	int hits;
	int viewport[1024];

	glGetIntegerv(GL_VIEWPORT, viewport);
	
	glSelectBuffer(512, selectBuf);
	
	glRenderMode(GL_SELECT);
	
	glInitNames();
	glPushName(0);

	glMatrixMode(GL_PROJECTION);
	glPushMatrix();
	glLoadIdentity();

	
	gluPickMatrix ((GLdouble)x, (GLdouble)(viewport[3] - y), 2, 2, viewport);
	
	if (x > windowHeight)//windowHeight == windowWidth*.75
		glOrtho(0, windowWidth*.25, windowHeight, 0,  -1, 1); //toolbar
	else if (drawType != 2)
		gluPerspective(80, 1, .1, 200);	
	else if (drawType == 2)
		glOrtho(-viewsWidth, viewsWidth, -viewsWidth, viewsWidth, -1, 1);
	
	glClear(GL_DEPTH_BUFFER_BIT);	
	glMatrixMode(GL_MODELVIEW);

	if (x > windowHeight)	
		drawToolbar(GL_SELECT);
	else if (drawType != 2)
		drawRendered(GL_SELECT);
	else if (drawType == 2)
		drawTextField(GL_SELECT);
	
	hits = glRenderMode(GL_RENDER);
	unsigned int currentName;
	currentName = processHits(hits, selectBuf);
	
	glMatrixMode(GL_PROJECTION);
	glPopMatrix();

	glMatrixMode(GL_MODELVIEW);

}

It does not seem to be able to pick up any polygons in the toolbar which is located at the right fourth of the screen. it notices a click, but does not give any hits. the other ortho, when drawType == 2, works fine. but this does not work correctly when x > windowWidth*.75 .
any help?

<name>,

your code looks ok to me. I suspect the problem is in one of your functions:

// what's going on in these?
if (x > windowHeight)		
drawToolbar(GL_SELECT);	
else if (drawType != 2)		
drawRendered(GL_SELECT);	
else if (drawType == 2)		
drawTextField(GL_SELECT);
		
hits = glRenderMode(GL_RENDER);	

unsigned int currentName;	

// what's going on in here?
currentName = processHits(hits, selectBuf);
