GetImageForCheckBox is an overridden TBitmap function used to get the bitmap displayed for a Checkbox at the specified location in the grid control. GetImageForCheckBox calls the inherited GetImageForCheckBox method using the passed arguments to get the return value. GetImageForCheckBox signals the OnUserCheckboxBitmap event handler when it has been assigned in the control to allow overriding the TBitmap used for the desired TCheckboxState.
