Thanks Andres, You are correct: STATE_SYSTEM_MIXED Indicates that the state of a three-state check box or toolbar button is not determined. The check box is neither checked nor unchecked and is therefore in the third or mixed state.
And visually the checkbox has an inner green box with a white border around the green box and between it and the black border of the check box.
