Color state problems

[alexsb]

Hi,

I’m having problems with the color state.

The following code does not do what it’s supposed to do:

	gl.glColor3f(0.5f, 0.5f, 0.5f);
		gl.glLineWidth(3.0f);
		
		// should be grey and is
		gl.glBegin(GL.GL_LINES);
		gl.glVertex3f(-1.0f, 1.0f, 0.0f);
		gl.glVertex3f(0.0f, 1.0f, 0.0f);
		gl.glEnd();
		
		gl.glPushAttrib(GL.GL_COLOR_BUFFER_BIT);
		gl.glColor3f(1.0f, 0.0f, 0.0f);
		
		// should be red and is
		gl.glBegin(GL.GL_LINES);
		gl.glVertex3f(-1.0f, 2.0f, 0.0f);
		gl.glVertex3f(0.0f, 2.0f, 0.0f);
		gl.glEnd();
		
		gl.glPopAttrib();
		
		// should be grey but is red
		gl.glBegin(GL.GL_LINES);
		gl.glVertex3f(-1.0f, 3.0f, 0.0f);
		gl.glVertex3f(0.0f, 3.0f, 0.0f);
		gl.glEnd();

so, the color state is not restored properly.

Any ideas what causes that?

Cheers,

Alex

The symbolic mask constants and their associated GL state
are as follows (the second column lists which attributes are
saved):

  GL_COLOR_BUFFER_BIT	   GL_ALPHA_TEST enable	bit
			   Alpha test function and reference value
			   GL_BLEND enable bit
			   Blending source and destination functions
			   Constant blend color
			   Blending equation
			   GL_DITHER enable bit
			   GL_DRAW_BUFFER setting
			   GL_COLOR_LOGIC_OP enable bit
			   GL_INDEX_LOGIC_OP enable bit
			   Logic op function
			   Color mode and index	mode clear values
			   Color mode and index	mode writemasks
